Some inspiration from an earlier client by Luke Stras. The MSS clamping was inspired by mssclampfw by Marc Boucher with acknowledgements to Rebel.com (http://www.rebel.com). However, the actual MSS clamping code is original and is licensed under the GPL, unlike the original mssclampfw. Introduction ============ pppoe is a user-space redirector which permits the use of PPPoE (Point-to-Point Over Ethernet) with Linux. PPPoE is used by many DSL service providers. Installation ============ Requirements ------------ 1) Linux 2.2.9 or later on Intel, Sparc or PowerPC. It may work on Alpha, too -- anyone care to let me know? OR Linux 2.0.36 or later. OR FreeBSD, NetBSD or OpenBSD with BPF support, though this is old, unmaintained, and may no longer work. 2) pppd 2.3.10 or later. Versions 2.3.7 and later work unless you use demand-dialling. For demand dialling, you *must* use 2.3.10 or later. QUICKSTART ---------- If you're lucky, the "quickstart" method will work. After unpacking the archive, become root and type: ./go This should configure, compile and install the software and set up your DSL connection. You'll have to answer a few questions along the way. If you want the GUI wrapper, type: ./go-gui If ./go and ./go-gui didn't work, read the rest of this README. Compiling --------- Compile and install pppd if you don't already have it. Then: 1) Unpack: $ tar xzvf rp-pppoe-xxx.tar.gz 2) Change to source directory: $ cd src 3) Configure: $ ./configure 4) Compile: $ make 4) Install (this step must be done as root) # make install 5) Now read doc/HOW-TO-CONNECT -- Dianne Skoll | Roaring Penguin Software Inc. http://www.roaringpenguin.com rp-pppoe-3.12/doc/0000755000076400007640000000000012620655110012066 5ustar dfsdfsrp-pppoe-3.12/doc/PROBLEMS0000644000076400007640000000007712620655110013240 0ustar dfsdfs# LIC: GPL Problems?

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. rp-pppoe-3.12/doc/CHANGES0000644000076400007640000002725412620655110013073 0ustar dfsdfs# LIC: GPL Changes from version 3.11 to 3.12: - Update author's name to "Dianne Skoll" - Add "-W" option to pppoe executable to explicitly set a Host-Unique value - Fix a few compiler warnings and configure script bugs. - Removed dead code Changes from Version 3.10 to 3.11: - Make the rp-pppoe.so plugin avoid calling exit() if the "persist" pppd option was given. - Permit both PPPoE server and client to specify an MTU/MRU of 1500 assuming the underlying Ethernet interface has an MTU of at least 1508. The larger MTU is negotiated per RFC 4638. NOTE: Only available with kernel-mode plugin, not user-mode pty redirector. - Get rid of hard-coded nobsdcomp, nodeflate, novj and novjccomp options in pppoe-server. - Apply patch from Philip Prindeville to allow cross-compiling. - Handle UNIT=xxx directive in pppoe-connect. (Keith Waters) - Add "-i" flag to pppoe-server to ignore PADIs if there are no free sessions. Change suggested by Miroslav Lednicky. - Ignore PADTs not destined for our ethernet address. - Add "-X " option to pppoe-server. - Cleanup Makefile.in. (Philip Prindeville) - In plugin, don't set devnam if it's already set. (Mike Ireton) - Eliminate race condition in signal handling. - pppoe-server: Add -q and -Q options to allow specification of path to pppd and pppoe programs respectively. - Add a few more sanity checks to pppoe-server packet handling. - Use -fno-strict-aliasing when compiling with gcc to avoid possible problems from -O2 optimization level. Changes from Version 3.9 to 3.10: (30 June 2008) - Fixed compilation problems on various platforms. - The Makefiles now use (standard) DESTDIR instead of (non-standard) RPM_INSTALL_ROOT to relocate installed files. - Spec file has been updated (it had languished since 3.6.) Changes from Version 3.8 to 3.9: (21 June 2008) - pppoe-server has new "-x" option to limit the number of sessions per MAC address. - Added proper timeout handling while waiting for PADO/PADS. - Fix race condition with some access concentrators that move very quickly into session mode (problem noted by Luigi Sgro) - Fixed compilation problem on BSD. - Fixed compilation problems with old versions of gcc - Remove superfluous options in scripts/pppoe-connect.in Changes from Version 3.7 to 3.8: (2 April 2006) - Adjusted code and made it possible to disable debugging code to shrink size of pppoe executable. - Fixed bug in MD5 code that caused pppoe-server to segfault on 64-bit machines. - Made various functions and variables static that didn't need to be visible outside their source files. Changes from Version 3.6 to 3.7: - Fixed typo in the firewall-standalone sample firewall script. Fix courtesy of Robert Vogelgesang - Added -O option to pppoe-server to let you specify a different default options file for pppd instead of /etc/ppp/pppoe-server-options Feature courtesy of Robert Vogelgesang - Fixed some silliness and incorrectness in configure.in. Feature courtesy of Robert Vogelgesang - Fixed a typo in pppoe-connect.in that made it fail if used with the kernel-mode plugin. - Make pppoe-server prepend "nic-" to interface name if used with kernel-mode plugin. This lets you use interfaces that don't start with "eth" more easily. Changes from Version 3.5 to 3.6: - Changed the names of commands from adsl-* to pppoe-* to more logically name the scripts. NOTE INCOMPATIBILITY: OLD NAME NEW NAME adsl-start pppoe-start adsl-stop pppoe-stop adsl-status pppoe-status adsl-connect pppoe-connect adsl-setup pppoe-setup - Changed sample firewall scripts to use iptables instead of the old ipchains command. - Updated KERNEL-MODE-PPPOE instructions to reflect more modern pppd that is commonly distributed. - Make the userland pppoe daemon run as "nobody" if possible, once session has started. - Make userland pppoe program somewhat safe if it is installed SUID or SGID. Note that I still do *NOT* recommend a SUID/SGID pppoe. - Fix long-standing bug in pppoe-server that passed arguments to pppd in the wrong order. - Fix kernel-mode plugin. It was broken by changes to pppd. The pppd maintainers fixed their version of the plugin, but neglected to inform me. Thanks a lot, guys! - Make plugin accept argument of the form "nix-XXXX" to force it to use device "XXXX" as the Ethernet interface. This allows the use of devices whose names do not start with "eth" Changes from Version 3.4 to 3.5: - Fixes for compilation on Solaris. Changes from Version 3.3 to 3.4: - INCOMPATIBILITY WITH EARLIER VERSIONS: Kernel-mode plugin now is built against latest CVS ppp source rather than Michal Ostrowski's patched version. If you use kernel-mode PPPoE, you MUST use the CVS version of the ppp source code with rp-pppoe 3.4. - Print PPPoE session number when connection terminates. Thanks to Alexander Dalloz for suggesting this. - Fixed a bug in MSS clamping -- it now works with protocol-field compression. Thanks to Gerd v. Egidy for the patch. - Ignore SIGINT and SIGTERM so LCP termination packets make it out. Changes from Version 3.2 to 3.3: - Client works on Solaris again. It was broken in 3.2. - Added DEFAULTROUTE=yes|no option to configuration file. - Server parses address pool file better. - Server address pool allows ranges of addresses on a line: a.b.c.d-e - Added "-d" (=debug) and "-P" (=check pool file syntax) options to pppoe-server. Changes from Version 3.1 to 3.2: - Client now ignores PADT's if they are from the wrong source MAC address or to the wrong destination MAC address. - Minor fixes to Makefile.in for Turbolinux. Changes from Version 3.0 to 3.1: - Improved KERNEL-MODE-PPPOE instructions - Works with patched pppd 2.4.1 - Many improvements to server: Added "-u" and "-r" options; server can now respond to request on multiple Ethernet interfaces. - SECURITY BUG FIX: Server now ignores PADT's if they are from the wrong source MAC address. You are STRONGLY RECOMMENDED to upgrade to 3.1 if you use pppoe-server in production. Changes from Version 2.8 to 3.0: - Many small improvements to server. Server now only makes one discovery socket, systemwide, with addition of "-n" option to pppoe. - Fixes for compilation problems on BSD, Solaris and some Linux platforms. - Added "-p" option to pppoe-server to allow you to specify a pool of IP addresses to assign to clients. - Added GUI system (tkpppoe). This work was funded by Iospan Wireless, Inc. The GUI includes a Set-UID wrapper (pppoe-wrapper) which allows ordinary users to control a link (if so authorized.) I believe the wrapper script is secure, but please audit the source code (gui/wrapper.c) if you have any concerns. - Changes to scripts and pppoe.conf. DNS setup is now dynamic (happens each time adsl-connect runs.) - Made relay.c check packet lengths rigorously; made it throw out Ethernet frame padding on session packets as well as discovery packets. Changes from Version 2.7 to 2.8: - Added init scripts for TurboLinux, courtesy of Yasuhiro Sumi. - Made relay.c check packet lengths rigorously; made it throw out Ethernet frame padding on discovery packets. *** NOTE: 2.7 was not released publicly Changes from Version 2.6 to 2.7: - Completely restructured source file tree. - Much internal restructuring to eliminate a bunch of global variables. - adsl-connect now executes /etc/ppp/adsl-lost whenever connection is dropped or cannot be established. - Split pppoe.c into pppoe.c and discovery.c. - Added relay agent (pppoe-relay). - Made adsl-connect script use the "-U" (host-unique) option to better support multiple PPPoE links. - Added support for kernel-mode PPPoE (EXPERIMENTAL, UNSUPPORTED!) - Added "-o" option to PPPoE server; encoded server PID in pppoe-server cookie. Changes from Version 2.5 to 2.6: - Code should now compile cleanly on Caldera and Slackware Linux - Fixed rp-pppoe.spec file to work on Mandrake and Red Hat. - Deleted some obsolete files - Fixed bug in Solaris/x86 port (thanks to Philippe Levan) - Made shell scripts nicer under Solaris (again, Philippe Levan) - Made adsl-status look under /var/run and /etc/ppp for PID files. Should fix problems with NetBSD. - Added PPPD_EXTRA to pppoe.conf; made the PID file depend on the config file name. This makes it easier to run multiple PPPoE sessions. Changes from Version 2.4 to 2.5: - Tested for zero-length TCP option-length field, and for reverse-packing of type/code bitfields. Thanks to Robert Schlabbach for pointing out these problems. - Set umask to 077 in adsl-setup.in to protect created files like /etc/ppp/pap-secrets. Changes from Version 2.3 to 2.4: - Fixed spec file to automatically add .gz extension to man files as required - Tightened firewall rules. - Better check for /var/run in adsl-status; minor shell script fixes and cleanups for NetBSD and Solaris. - Added FAQ to HOW-TO-CONNECT regarding running a script each time a connection is made. Changes from Version 2.2 to 2.3: - Fixed the init script to create/remove /var/lock/subsys/adsl (patch courtesy of Charley Carter.) - Added support (under Linux) for N_HDLC line discipline which should greatly reduce CPU usage. My tests show it cuts CPU usage in half. My 486 DX2/66 gets 800 kb/s at 22% CPU usage. - adsl-connect uses "setsid" (if available) so that adsl-stop doesn't kill its caller. There is (IMO) a bug in pppd which kills all processes in its process group if the "pty" option is used. The setsid program gets around this bug, on Linux at least. - Port to Solaris, courtesy of David Holland. - Renamed spec file from "spec" to "rp-pppoe.spec" and made some cleanups. NOTE: Red Hat, in their infinite wisdom, decided to make the new RPM compress man pages automatically. You may have problems building RPM's from source unless you get the latest rpm package and make sure it compresses man pages. Changes from Version 2.1 to 2.2: - Added "-f" option to pppoe to allow use of any Ethernet frame type for PPPoE. USE WITH CAUTION -- this is a workaround for broken DSL providers, not something you should monkey with freely! - Added pppoe-sniff program to help expose non-standard PPPoE implementations. Changes from Version 2.0 to 2.1: - Fixed minor bugs in bounds-checking - Modified adsl-status to use output of "netstat -r -n" to determine whether or not link is up.

PPPoE is used by many DSL providers and some wireless providers. Follow these steps and you should have your PPPoE service up and running. 0. Install the rp-pppoe-software -------------------------------- You should have already done this by the time you're reading this. If not, go back and read README. 1. Set up your Ethernet hardware -------------------------------- First, make sure the Ethernet card you intend to use with the modem is visible to the Linux kernel. Just how to do this is beyond the scope of this document. However, if the card is the only Ethernet card in the system, executing: ifconfig eth0 should display something like this: eth0 Link encap:Ethernet HWaddr 00:60:67:62:31:D4 plust some more lines. Your HWaddr will be different. As long as you see the HWaddr line, your card should be working. DO NOT assign an IP address to the Ethernet card. DO NOT configure the card to come up at boot time. 2. Configure various files -------------------------- Several files need editing. The easiest way to do this is to run the following command as root: pppoe-setup Answer the questions and you should be all set. If you want to know what goes on behind the scenes, continue reading this document. If you don't care and your connection works, stop reading. :-) 3. Edit pap-secrets ------------------- Edit the "pap-secrets" file, inserting your proper user-ID and password. Install the file (or copy the relevant lines) to /etc/ppp/pap-secrets. Your ISP may use CHAP authentication. In this case, add the line to /etc/ppp/chap-secrets. 4. Edit /etc/ppp/pppoe.conf ----------------------------- The file /etc/ppp/pppoe.conf contains configuration information for the DSL connection. You need to edit the following items: - Change ETH=eth1 to the correct Ethernet device for your modem. - Change USER=bxxxnxnx@sympatico.ca to your proper DSL user-ID. Don't edit any of the other settings unless you're an expert. 5. Set up DNS ------------- If you are using DNS servers supplied by your ISP, edit the file /etc/resolv.conf to contain these lines: nameserver ip_addr_of_first_dns_server nameserver ip_addr_of_second_dns_server For example: nameserver 204.101.251.1 nameserver 204.101.251.2 6. Firewall your machine ------------------------ MAKE SURE YOU FIREWALL YOUR MACHINE. A sample firewall script is given in the shell script "firewall" To install the script: a) Copy it to /etc/rc.d/init.d/firewall b) Type: chkconfig firewall on c) Start the firewall: sh /etc/rc.d/init.d/firewall start (The above procedure works ONLY on Red Hat-like systems.) You may want to tweak the script somewhat. 7. Bring up the connection at boot time --------------------------------------- On a Red Hat system, the installation procedure should have installed a script called /etc/rc.d/init.d/pppoe. To bring up the connection at boot time, just type this command as root: chkconfig --add pppoe On non-Red-Hat systems, add this line to the end of /etc/rc.d/rc.local: /usr/sbin/pppoe-start 8. Configure LAN Hosts ---------------------- If you have a LAN behind the firewall, you have to lower the TCP maximum segment size from the normal 1460 to 1452 (or better, 1412.) You have two options: Either set the MTU of all the interfaces on other hosts on the LAN to 1452, or use the "-m 1412" option to pppoe. The "-m" option for pppoe is far simpler and makes it easier to add hosts to the LAN, but consumes some extra CPU time. If you want to manually configure the LAN hosts, here's how: In Linux, use: "ifconfig eth0 mtu 1452". For best results, put this in an /etc/rc.d/rc.local script. For Windows, machines, see http://lan.cns.ksu.edu/OS/WIN95/slip95.htm. Set the MaxMTU to 1452. 9. Commands to control the PPPoE link ------------------------------------- As root, bring up the link by typing: pppoe-start As root, bring down the link by typing: pppoe-stop That's it! -- Dianne Skoll | Roaring Penguin Software Inc. http://www.roaringpenguin.com | PROBLEMS! DIANNE, IT DOESN'T WORK! --------------------------------- Here are some problems PPPoE users have encountered. ----------------------------------------------------------------------------- A) Can't see the Ethernet interface Well, I can't really help you here. To use these instructions, you must have Linux working to the point where it recognizes your Ethernet card. If you type "ifconfig ethx" and you get back a HWAddr value, your Ethernet card is probably OK. But I really can't help with hardware configuration issues. ----------------------------------------------------------------------------- B) Connection seems to come up, but I can't browse the web or ping anything You probably don't have DNS set up. See step 6. ----------------------------------------------------------------------------- C) Can't compile PPPoE Make sure you have "make", the C compiler and all development header files installed. I only test rp-pppoe on Linux. It might not work on *BSD and probably won't work on any other version of UNIX. ----------------------------------------------------------------------------- D) pppd complains about (i) "unknown option pty" or (ii) "pty option precludes specifying device name" (i) Your pppd is too old. You need at least 2.3.7. (ii) Your /etc/ppp/options file is not empty. Empty it! ----------------------------------------------------------------------------- E) pppoe dies with the log message "Message too long" You set the MTU of the Ethernet interface connected to the DSL modem to less than 1500. Don't do that. ----------------------------------------------------------------------------- F) Internal hosts can't see the Internet Do you have masquerading set up? I can't help you in great detail, but see the IPCHAINS-HOWTO and the IP-Masquerade mini-HOWTO. ----------------------------------------------------------------------------- G) Authentication fails Make sure you have the right secret in /etc/ppp/pap-secrets. Your ISP may be using CHAP; it won't hurt to copy the line to /etc/ppp/chap-secrets. Also, MAKE SURE that /etc/ppp/options is EMPTY. The "pppoe-connect" script supplies all required options on the command line; additional options in /etc/ppp/options may mess things up. ----------------------------------------------------------------------------- H) VPN software does not work If you are using VPN software on a Windows or Linux machine with another Linux machine running PPPoE as the gateway, you MUST NOT use the "-m" option to pppoe. This alters IP packets, which will break any VPN which uses IPSec. In /etc/ppp/pppoe.conf, set CLAMPMSS to "no". You'll also have to reduce the MTU on the hosts behind the gateway to 1452. ----------------------------------------------------------------------------- I) I can browse some web sites just fine, but others stall forever. There is probably a buggy router or firewall between you and the Web server. One possible workaround: In /etc/ppp/pppoe.conf, find the line which reads: CLAMPMSS=1412 Try lowering the 1412 until it works (go down in steps of 100 or so.) Each time you lower the value, you have to restart your connection like this: pppoe-stop; pppoe-start This should work around buggy routers which do not support Path MTU discovery. ----------------------------------------------------------------------------- J) Whenever I connect using DSL, my internal LAN no longer sees the gateway You are more than likely running a 2.0.X Linux kernel. To solve this problem, give the Ethernet card connected to the DSL modem a fake IP address. For example, if eth0 is your internal LAN card and eth1 goes to the DSL modem, do something like this: ifconfig eth1 10.0.0.1 netmask 255.255.255.0 (You may have to choose a different IP address; experiment.) ----------------------------------------------------------------------------- K) How can I run a script every time I connect and get a new IP address? Put the script in /etc/ppp/ip-up. See the pppd(8) man page. ----------------------------------------------------------------------------- L) Nothing works! You may need to put your Ethernet card in half-duplex, 10Mb/s mode to work with the DSL modem. You may have to run a DOS program to do this, or pass special parameters to the Linux driver. Some providers object to attempts to set the MRU or MTU. Try removing "mtu 1492 mru 1492" from PPP_STD_OPTIONS in the pppoe-connect script. This problem has been seen with an ISP in Hong Kong. Your DSL provider may be using non-standard PPPoE frames or require something special in the Service-Name field. If you have two computers, you can try sniffing out these values with the "pppoe-sniff" program. Type "man pppoe-sniff" for details. If you don't have two computers, you'll have to ask your DSL provider if it uses non-standard PPPoE frames or special Service-Name fields. Good luck getting an answer... If pppoe-sniff indicates that nothing is amiss, make sure the Ethernet card associated with the DSL modem does NOT have a valid IP address. (NOTE: For 2.0 kernels, you may have to give it a fake IP address which is not on your internal subnet. Something like 192.168.42.42 might work if you are not using 192.168.42.*) If you are using synchronous PPP on a slow machine, try switching to asynchronous PPP. Make sure no entries in the routing table go through the Ethernet card connected to the DSL modem. You might want to add these lines in pppoe-connect: ifconfig ethx down ifconfig ethx up mtu 1500 which should reset things to sane values. rp-pppoe-3.12/doc/KERNEL-MODE-PPPOE0000644000076400007640000000662412620655110014404 0ustar dfsdfs# LIC: GPL RP-PPPoE now supports kernel-mode PPPoE on Linux kernels 2.4 or newer. However, the default "./go" build procedure does not make kernel-mode support. Here's what you need to do: 0) Make sure you are running kernel 2.4 or newer on the machine you will build rp-pppoe on. You must have the following kernel configuration settings: CONFIG_PPP=m or CONFIG_PPP=y CONFIG_PPP_ASYNC=m or CONFIG_PPP_ASYNC=y CONFIG_PPP_SYNC_TTY=m or CONFIG_PPP_SYNC_TTY=y CONFIG_PPP_DEFLATE=m or CONFIG_PPP_DEFLATE=y CONFIG_PPP_BSDCOMP=m or CONFIG_PPP_BSDCOMP=y CONFIG_PPPOE=m or CONFIG_PPPOE=y CONFIG_N_HDLC=m or CONFIG_N_HDLC=y CONFIG_UNIX98_PTYS=y You also need a /dev/ppp file: mknod --mode=664 /dev/ppp c 108 0 You might want to add these lines to /etc/modules.conf: alias char-major-108 ppp_generic alias tty-ldisc-3 ppp_async alias tty-ldisc-13 n_hdlc alias tty-ldisc-14 ppp_synctty alias net-pf-24 pppoe 1) If you are running pppd older than 2.4.0, check out the latest version of the PPP software from the CVS repository at cvs.samba.org. Here's how to do this: cvs -d :pserver:cvs@pserver.samba.org:/cvsroot login # When prompted for a password, type "cvs" # Change to the directory in which you want to store the PPP source # code. cd /path/to/checked/out/sources # Check out the source cvs -z5 -d :pserver:cvs@pserver.samba.org:/cvsroot co ppp If you are running pppd 2.4.0 or newer, and have the pppd development headers installed, you can skip steps 1 and 2. 2) The source gets checked out into a subdirectory called ppp. If the source ends up in /path/to/checked/out/sources/ppp, then call that path $PPPDIR. Build and install the checked-out ppp code according to its instructions. 3) Unpack rp-pppoe. 4) In the rp-pppoe directory, change to src/ and type: ./configure --enable-plugin=$PPPDIR where $PPPDIR, of course, refers to the checked-out "ppp" directory from cvs.samba.org. If you didn't check out the PPP software from cvs.samba.org, use: ./configure --enable-plugin This will work if the header pppd/pppd.h is located in /usr/include or /usr/local/include. 4) Type make; make install 5) Edit /etc/ppp/pppoe.conf to include this line: LINUX_PLUGIN=/etc/ppp/plugins/rp-pppoe.so After that, pppoe-start should use kernel-mode PPPoE. The rp-pppoe.so plugin adds the following command-line options to pppd: ethXXX -- Use interface ethXXX as Ethernet interface brXXX -- Use interface brXXX as Ethernet interface nic-XXXX -- Use interface XXXX as the Ethernet interface rp_pppoe_service SERVICE_NAME -- Specify desired service name rp_pppoe_ac NAME -- Specify desired access concentrator name rp_pppoe_verbose 0|1 -- Print names of access concentrators rp_pppoe_sess nnnn:aa:bb:cc:dd:ee:ff -- Attach to existing session 'nnnn' on AC with Ethernet address aa:bb:cc:dd:ee:ff This skips the discovery phase. rp_pppoe_mac aa:bb:cc:dd:ee:ff -- only accept PADOs from specified MAC address The kernel-mode PPPoE plugin permits an MTU of up to 1500 on the PPP interface providing that the MTU on the underlying Ethernet interface is at least 1508. In /etc/ppp/pppoe.conf, set MTU=1500 and MRU=1500 to enable the larger PPP MTU. The larger PPP MTU is negotiated according to RFC 4638. -- Dianne Skoll rp-pppoe-3.12/man/0000755000076400007640000000000012620655112012076 5ustar dfsdfsrp-pppoe-3.12/man/pppoe.80000644000076400007640000002265612620655111013324 0ustar dfsdfs.\" LIC: GPL .TH PPPOE 8 "5 October 2015" .UC 4 .SH NAME pppoe \- user-space PPPoE client. .SH SYNOPSIS .B pppd pty 'pppoe \fR[\fIpppoe_options\fR]\fB' \fR[\fIpppd_options\fR] .P .B pppoe -A \fR[\fIpppoe_options\fR] .SH DESCRIPTION \fBpppoe\fR is a user-space client for PPPoE (Point-to-Point Protocol over Ethernet) for Linux and other UNIX systems. \fBpppoe\fR works in concert with the \fBpppd\fR PPP daemon to provide a PPP connection over Ethernet, as is used by many DSL service providers. .SH OPTIONS .TP .B \-I \fIinterface\fR The \fB\-I\fR option specifies the Ethernet interface to use. Under Linux, it is typically \fIeth0\fR or \fIeth1\fR. The interface should be "up" before you start \fBpppoe\fR, but should \fInot\fR be configured to have an IP address. .TP .B \-T \fItimeout\fR The \fB\-T\fR option causes \fBpppoe\fR to exit if no session traffic is detected for \fItimeout\fR seconds. I recommend that you use this option as an extra safety measure, but if you do, you should make sure that PPP generates enough traffic so the timeout will normally not be triggered. The best way to do this is to use the \fIlcp-echo-interval\fR option to \fBpppd\fR. You should set the PPPoE timeout to be about four times the LCP echo interval. .TP .B \-D \fIfile_name\fR The \fB\-D\fR option causes every packet to be dumped to the specified \fIfile_name\fR. This is intended for debugging only; it produces huge amounts of output and greatly reduces performance. .TP .B \-V The \fB\-V\fR option causes \fBpppoe\fR to print its version number and exit. .TP .B \-A The \fB\-A\fR option causes \fBpppoe\fR to send a PADI packet and then print the names of access concentrators in each PADO packet it receives. Do not use this option in conjunction with \fBpppd\fR; the \fB\-A\fR option is meant to be used interactively to give interesting information about the access concentrator. .TP .B \-S \fIservice_name\fR Specifies the desired service name. \fBpppoe\fR will only initiate sessions with access concentrators which can provide the specified service. In most cases, you should \fInot\fR specify this option. Use it only if you know that there are multiple access concentrators or know that you need a specific service name. .TP .B \-C \fIac_name\fR Specifies the desired access concentrator name. \fBpppoe\fR will only initiate sessions with the specified access concentrator. In most cases, you should \fInot\fR specify this option. Use it only if you know that there are multiple access concentrators. If both the \fB\-S\fR and \fB\-C\fR options are specified, they must \fIboth\fR match for \fBpppoe\fR to initiate a session. .TP .B \-U Causes \fBpppoe\fR to use the Host-Uniq tag in its discovery packets. This lets you run multiple \fBpppoe\fR daemons without having their discovery packets interfere with one another. You must supply this option to \fIall\fR \fBpppoe\fR daemons if you intend to run multiple daemons simultaneously. The specific Host-Uniq value used is the hexadecimal representation of the \fBpppoe\fR process's PID. .TP .B \-W value Causes \fBpppoe\fR to use the Host-Uniq tag in its discovery packets, and furthermore to set the value of Host-Uniq to \fIvalue\fR. Use with caution. Note that \fB\-W\fR and \fB\-U\fR are mutually-incompatible. .TP .B \-s Causes \fBpppoe\fR to use \fIsynchronous\fR PPP encapsulation. If you use this option, then you \fImust\fR use the \fBsync\fR option with \fBpppd\fR. You are encouraged to use this option if it works, because it greatly reduces the CPU overhead of \fBpppoe\fR. However, it MAY be unreliable on slow machines -- there is a race condition between pppd writing data and pppoe reading it. For this reason, the default setting is asynchronous. If you encounter bugs or crashes with Synchronous PPP, turn it off -- don't e-mail me for support! .TP .B \-m \fIMSS\fR Causes \fBpppoe\fR to \fIclamp\fR the TCP maximum segment size at the specified value. Because of PPPoE overhead, the maximum segment size for PPPoE is smaller than for normal Ethernet encapsulation. This could cause problems for machines on a LAN behind a gateway using PPPoE. If you have a LAN behind a gateway, and the gateway connects to the Internet using PPPoE, you are strongly recommended to use a \fB\-m 1412\fR option. This avoids having to set the MTU on all the hosts on the LAN. .TP .B \-p \fIfile\fR Causes \fBpppoe\fR to write its process-ID to the specified file. This can be used to locate and kill \fBpppoe\fR processes. .TP .B \-e \fIsess:mac\fR Causes \fBpppoe\fR to skip the discovery phase and move directly to the session phase. The session is given by \fIsess\fR and the MAC address of the peer by \fImac\fR. This mode is \fInot\fR meant for normal use; it is designed only for \fBpppoe-server\fR(8). .TP .B \-n Causes \fBpppoe\fR not to open a discovery socket. This mode is \fInot\fR meant for normal use; it is designed only for \fBpppoe-server\fR(8). .TP .B \-k Causes \fBpppoe\fR to terminate an existing session by sending a PADT frame, and then exit. You must use the \fB\-e\fR option in conjunction with this option to specify the session to kill. This may be useful for killing sessions when a buggy peer does not realize the session has ended. .TP .B \-d Causes \fBpppoe\fR to perform discovery and then exit, after printing session information to standard output. The session information is printed in exactly the format expected by the \fB\-e\fR option. This option lets you initiate a PPPoE discovery, perform some other work, and then start the actual PPP session. \fIBe careful\fR; if you use this option in a loop, you can create many sessions, which may annoy your peer. .TP .B \-f disc:sess The \fB\-f\fR option sets the Ethernet frame types for PPPoE discovery and session frames. The types are specified as hexadecimal numbers separated by a colon. Standard PPPoE uses frame types 8863:8864. \fIYou should not use this option\fR unless you are absolutely sure the peer you are dealing with uses non-standard frame types. If your ISP uses non-standard frame types, complain! .TP .B \-h The \fB\-h\fR option causes \fBpppoe\fR to print usage information and exit. .SH PPPOE BACKGROUND PPPoE (Point-to-Point Protocol over Ethernet) is described in RFC 2516 and is a protocol which allows the session abstraction to be maintained over bridged Ethernet networks. PPPoE works by encapsulating PPP frames in Ethernet frames. The protocol has two distinct stages: The \fIdiscovery\fR and the \fIsession\fR stage. In the discovery stage, the host broadcasts a special PADI (PPPoE Active Discovery Initiation) frame to discover any \fIaccess concentrators\fR. The access concentrators (typically, only one access concentrator) reply with PADO (PPPoE Active Discovery Offer) packets, announcing their presence and the services they offer. The host picks one of the access concentrators and transmits a PADR (PPPoE Active Discovery Request) packet, asking for a session. The access concentrator replies with a PADS (PPPoE Active Discovery Session-Confirmation) packet. The protocol then moves to the session stage. In the session stage, the host and access concentrator exchange PPP frames embedded in Ethernet frames. The normal Ethernet MTU is 1500 bytes, but the PPPoE overhead plus two bytes of overhead for the encapsulated PPP frame mean that the MTU of the PPP interface is at most 1492 bytes. This causes \fIall kinds of problems\fR if you are using a Linux machine as a firewall and interfaces behind the firewall have an MTU greater than 1492. In fact, to be safe, I recommend setting the MTU of machines behind the firewall to 1412, to allow for worst-case TCP and IP options in their respective headers. Normally, PPP uses the Link Control Protocol (LCP) to shut down a PPP link. However, the PPPoE specification allows the link to be shut down with a special PADT (PPPoE Active Discovery Terminate) packet. This client recognizes this packet and will correctly terminate if a terminate request is received for the PPP session. .SH DESIGN GOALS My design goals for this PPPoE client were as follows, in descending order of importance: .TP .B o It must work. .TP .B o It must be a user-space program and not a kernel patch. .TP .B o The code must be easy to read and maintain. .TP .B o It must be fully compliant with RFC 2516, the proposed PPPoE standard. .TP .B o It must never hang up forever -- if the connection is broken, it must detect this and exit, allowing a wrapper script to restart the connection. .TP .B o It must be fairly efficient. .P I believe I have achieved all of these goals, but (of course) am open to suggestions, patches and ideas. See my home page, http://www.roaringpenguin.com, for contact information. .SH NOTES For best results, you must give \fBpppd\fR an mtu option of 1492. I have observed problems with excessively-large frames unless I set this option. Also, if \fBpppoe\fR is running on a firewall machine, all machines behind the firewall should have MTU's of 1412. If you have problems, check your system logs. \fBpppoe\fR logs interesting things to syslog. You may have to turn on logging of \fIdebug\fR-level messages for complete diagnosis. .SH AUTHORS \fBpppoe\fR was written by Dianne Skoll , with much inspiration from an earlier version by Luke Stras.

If you omit \fIconfig_file\fR, the default file \fB/etc/ppp/pppoe.conf\fR is used. If you supply \fIinterface\fR and \fIuser\fR, then they override the Ethernet interface and user-name settings in the configuration file. .P Note that normally, you should \fInot\fR invoke \fBpppoe-connect\fR directly. Instead, use \fBpppoe-start\fR to bring up the PPPoE connection. .P \fBpppoe-connect\fR first reads a configuration file. It then brings up a PPPoE connection. If the connection ever drops, a message is logged to syslog, and \fBpppoe-connect\fR re-establishes the connection. In addition, each time the connection is dropped or cannot be established, \fBpppoe-connect\fR executes the script \fB/etc/ppp/pppoe-lost\fR if it exists and is executable. .P The shell script \fBpppoe-stop\fR causes \fBpppoe-connect\fR to break out of its loop, bring the connection down, and exit. .SH TECHNICAL DETAILS \fBpppoe-connect\fR uses the following shell variables from the configuration file: .TP .B ETH The Ethernet interface connected to the DSL modem (for example, eth0). .TP .B USER The PPPoE user-id (for example, b1xxnxnx@sympatico.ca). .TP .B PIDFILE A file in which to write the process-ID of the pppoe-connect process (for example, \fB/var/run/pppoe.pid\fR). Two additional files ($PIDFILE.pppd and $PIDFILE.pppoe) hold the process-ID's of the \fBpppd\fR and \fBpppoe\fR processes, respectively. .P By using different configuration files with different PIDFILE settings, you can manage multiple PPPoE connections.

The default is to fork and become a daemon. .TP .B \-I \fIinterface\fR The \fB\-I\fR option specifies the Ethernet interface to use. Under Linux, it is typically \fIeth0\fR or \fIeth1\fR. The interface should be "up" before you start \fBpppoe-server\fR, but need not have an IP address. You can supply multiple \fB\-I\fR options if you want the server to respond on more than one interface. .TP .B \-X \fIpidfile\fR This option causes \fBpppoe-server\fR to write its process ID to \fIpidfile\fR. Additionally, it keeps the file locked so that only a single process may be started for a given \fIpidfile\fR. .TP .B \-q \fI/path/to/pppd\fR Specifies the full path to the \fBpppd\fR program. The default is determined at compile time. One use of this option is to supply a wrapper program that modifies the arguments passed to pppd. This lets you do things not directly supported by the server (for example, specify IPv6 addresses.) .TP .B \-Q \fI/path/to/pppoe\fR Specifies the full path to the \fBpppoe\fR program. The default is determined at compile time. This option is only relevant if you are \fInot\fR using kernel-mode PPPoE. .TP .B \-T \fItimeout\fR This option is passed directly to \fBpppoe\fR; see \fBpppoe\fR(8) for details. If you are using kernel-mode PPPoE, this option has \fIno effect\fR. .TP .B \-C \fIac_name\fR Specifies which name to report as the access concentrator name. If not supplied, the host name is used. .TP .B \-S \fIname\fR Offer a service named \fIname\fR. Multiple \fB\-S\fR options may be specified; each one causes the named service to be advertised in a Service-Name tag in the PADO frame. The first \fB\-S\fR option specifies the default service, and is used if the PPPoE client requests a Service-Name of length zero. .TP .B \-m \fIMSS\fR This option is passed directly to \fBpppoe\fR; see \fBpppoe\fR(8) for details. If you are using kernel-mode PPPoE, this option has \fIno effect\fR. .TP .B \-x \fIn\fR Limit the number of sessions per peer MAC address to \fIn\fR. If a given MAC address attempts to create more than \fIn\fR sessions, then its PADI and PADR packets are ignored. If you set \fIn\fR to 0 (the default), then no limit is imposed on the number of sessions per peer MAC address. .TP .B \-s This option is passed directly to \fBpppoe\fR; see \fBpppoe\fR(8) for details. In addition, it causes \fBpppd\fR to be invoked with the \fIsync\fR option. .TP .B \-L \fIip\fR Sets the local IP address. This is passed to spawned \fBpppd\fR processes. If not specified, the default is 10.0.0.1. .TP .B \-R \fIip\fR Sets the starting remote IP address. As sessions are established, IP addresses are assigned starting from \fIip\fR. \fBpppoe-server\fR automatically keeps track of the pool of addresses and passes a valid remote IP address to \fBpppd\fR. If not specified, a starting address of 10.67.15.1 is used. .TP .B \-N \fInum\fR Allows at most \fInum\fR concurrent PPPoE sessions. If not specified, the default is 64. .TP .B \-O \fIfname\fR This option causes \fBpppoe-server\fR to tell \fBpppd\fR to use the option file \fIfname\fR instead of the default \fI/etc/ppp/pppoe-server-options\fR. .TP .B \-p \fIfname\fR Reads the specified file \fIfname\fR which is a text file consisting of one IP address per line. These IP addresses will be assigned to clients. The number of sessions allowed will equal the number of addresses found in the file. The \fB\-p\fR option overrides both \fB\-R\fR and \fB\-N\fR. In addition to containing IP addresses, the pool file can contain lines of the form: .nf a.b.c.d-e .fi which includes all IP addresses from a.b.c.d to a.b.c.e. For example, the line: .nf 1.2.3.4-7 .fi is equivalent to: .nf 1.2.3.4 1.2.3.5 1.2.3.6 1.2.3.7 .fi .TP .B \-r Tells the PPPoE server to randomly permute session numbers. Instead of handing out sessions in order, the session numbers are assigned in an unpredictable order. .TP .B \-u Tells the server to invoke \fBpppd\fR with the \fIunit\fR option. Note that this option only works for \fBpppd\fR version 2.4.0 or newer. .TP .B \-o \fIoffset\fR Instead of numbering PPPoE sessions starting at 1, they will be numbered starting at \fIoffset\fR+1. This allows you to run multiple servers on a given machine; just make sure that their session numbers do not overlap. .TP .B \-f disc:sess The \fB\-f\fR option sets the Ethernet frame types for PPPoE discovery and session frames. The types are specified as hexadecimal numbers separated by a colon. Standard PPPoE uses frame types 8863:8864. \fIYou should not use this option\fR unless you are absolutely sure the peer you are dealing with uses non-standard frame types. .TP .B \-k The \fB\-k\fR option tells the server to use kernel-mode PPPoE on Linux. This option is available only on Linux kernels 2.4.0 and later, and only if the server was built with kernel-mode support. .TP .B \-i The \fB\-i\fR option tells the server to completely ignore PADI frames if there are no free session slots. .TP .B \-h The \fB\-h\fR option prints a brief usage message and exits. .SH OPERATION \fBpppoe-server\fR listens for incoming PPPoE discovery packets. When a session is established, it spawns a \fBpppd\fR process. The following options are passed to \fBpppd\fR: .nf nodetach noaccomp nobsdcom nodeflate nopcomp novj novjccomp default-asyncmap .fi In addition, the local and remote IP address are set based on the \fB\-L\fR and \fB\-R\fR options. The \fBpty\fR option is supplied along with a \fBpppoe\fR command to initiate the PPPoE session. Finally, additional \fBpppd\fR options can be placed in the file \fB/etc/ppp/pppoe-server-options\fR (which must exist, even if it is just empty!) Note that \fBpppoe-server\fR is meant mainly for testing PPPoE clients.

See the OPERATION section later in this manual for details on how \fBpppoe-relay\fR works. .SH OPTIONS .TP .B \-S \fIinterface\fR Adds the Ethernet interface \fIinterface\fR to the list of interfaces managed by \fBpppoe-relay\fR. Only PPPoE servers may be connected to this interface. .TP .B \-C \fIinterface\fR Adds the Ethernet interface \fIinterface\fR to the list of interfaces managed by \fBpppoe-relay\fR. Only PPPoE clients may be connected to this interface. .TP .B \-B \fIinterface\fR Adds the Ethernet interface \fIinterface\fR to the list of interfaces managed by \fBpppoe-relay\fR. Both PPPoE clients and servers may be connected to this interface. .TP .B \-n \fInum\fR Allows at most \fInum\fR concurrent PPPoE sessions. If not specified, the default is 5000. \fInum\fR can range from 1 to 65534. .TP .B \-i \fItimeout\fR Specifies the session idle timeout. If both peers in a session are idle for more than \fItimeout\fR seconds, the session is terminated. If \fItimeout\fR is specified as zero, sessions will never be terminated because of idleness. Note that the idle-session expiry routine is never run more frequently than every 30 seconds, so the timeout is approximate. The default value for \fItimeout\fR is 600 seconds (10 minutes.) .TP .B \-F The \fB\-F\fR option causes \fBpppoe-relay\fR \fInot\fR to fork into the background; instead, it remains in the foreground. .TP .B \-h The \fB\-h\fR option prints a brief usage message and exits. .SH OPERATION \fBpppoe-relay\fR listens for incoming PPPoE PADI frames on all interfaces specified with \fB-B\fR or \fB-C\fR options. When a PADI frame appears, \fBpppoe-relay\fR adds a Relay-Session-ID tag and broadcasts the PADI on all interfaces specified with \fB-B\fR or \fB-S\fR options (except the interface on which the frame arrived.) Any PADO frames received are relayed back to the client which sent the PADI (assuming they contain valid Relay-Session-ID tags.) Likewise, PADR frames from clients are relayed back to the matching access concentrator. When a PADS frame is received, \fBpppoe-relay\fR enters the two peers' MAC addresses and session-ID's into a hash table. (The session-ID seen by the access concentrator may be different from that seen by the client; \fBpppoe-relay\fR must renumber sessions to avoid the possibility of duplicate session-ID's.) Whenever either peer sends a session frame, \fBpppoe-relay\fR looks up the session entry in the hash table and relays the frame to the correct peer. When a PADT frame is received, \fBpppoe-relay\fR relays it to the peer and deletes the session entry from its hash table. If a client and server crash (or frames are lost), PADT frames may never be sent, and \fBpppoe-relay\fR's hash table can fill up with stale sessions. Therefore, a session-cleaning routine runs periodically, and removes old sessions from the hash table. A session is considered "old" if no traffic has been seen within \fItimeout\fR seconds. When a session is deleted because of a timeout, a PADT frame is sent to each peer to make certain that they are aware the session has been killed. .SH EXAMPLE INVOCATIONS .nf pppoe-relay -C eth0 -S eth1 .fi The example above relays frames between PPPoE clients on the eth0 network and PPPoE servers on the eth1 network. .nf pppoe-relay -B eth0 -B eth1 .fi This example is a transparent relay -- frames are relayed between any mix of clients and servers on the eth0 and eth1 networks. .nf pppoe-relay -S eth0 -C eth1 -C eth2 -C eth3 .fi This example relays frames between servers on the eth0 network and clients on the eth1, eth2 and eth3 networks. .SH AUTHORS \fBpppoe-relay\fR was written by Dianne Skoll .

Note that \fBpppoe.conf\fR is used only by the various pppoe-* shell scripts, not by \fBpppoe\fR itself. \fBpppoe.conf\fR consists of a sequence of shell variable assignments. The variables and their meanings are: .TP .B ETH The Ethernet interface connected to the DSL modem (for example, eth0). .TP .B USER The PPPoE user-id (for example, b1xxnxnx@sympatico.ca). .TP .B SERVICENAME If this is not blank, then it is passed with the \fB\-S\fR option to \fBpppoe\fR. It specifies a service name to ask for. Usually, you should leave it blank. .TP .B ACNAME If this is not blank, then it is passed with the \fB\-C\fR option to \fBpppoe\fR. It specifies the name of the access concentrator to connect to. Usually, you should leave it blank. .TP .B DEMAND If set to a number, the link is activated on demand and brought down after after \fBDEMAND\fR seconds. If set to \fBno\fR, the link is kept up all the time rather than being activated on demand. .TP .B DNSTYPE One of \fBNOCHANGE\fR, \fBSPECIFY\fR or \fBSERVER\fR. If set to NOCHANGE, \fBpppoe-connect\fR will not adjust the DNS setup in any way. If set to SPECIFY, it will re-write /etc/resolv.conf with the values of DNS1 and DNS2. If set to \fBSERVER\fR, it will supply the \fIusepeerdns\fR option to \fBpppd\fR, and make a symlink from /etc/resolv.conf to /etc/ppp/resolv.conf. .TP .B DNS1, DNS2 IP addresses of DNS servers if you use DNSTYPE=SPECIFY. .TP .B NONROOT If the line \fBNONROOT=OK\fR (exactly like that; no whitespace or comments) appears in the configuration file, then \fBpppoe-wrapper\fR will allow non-root users to bring the conneciton up or down. The wrapper is installed only if you installed the rp-pppoe-gui package. .TP .B USEPEERDNS If set to "yes", then \fBpppoe-connect\fR will supply the \fIusepeerdns\fR option to \fBpppd\fR, which causes it to obtain DNS server addresses from the peer and create a new \fB/etc/resolv.conf\fR file. Otherwise, \fBpppoe-connect\fR will not supply this option, and \fBpppd\fR will not modify \fB/etc/resolv.conf\fR. .TP .B CONNECT_POLL How often (in seconds) \fBpppoe-start\fR should check to see if a new PPP interface has come up. If this is set to 0, the \fBpppoe-start\fR simply initiates the PPP session, but does not wait to see if it comes up successfully. .TP .B CONNECT_TIMEOUT How long (in seconds) \fBpppoe-start\fR should wait for a new PPP interface to come up before concluding that \fBpppoe-connect\fR has failed and killing the session. .TP .B PING A character which is echoed every \fBCONNECT_POLL\fR seconds while \fBpppoe-start\fR is waiting for the PPP interface to come up. .TP .B FORCEPING A character which is echoed every \fBCONNECT_POLL\fR seconds while \fBpppoe-start\fR is waiting for the PPP interface to come up. Similar to \fBPING\fR, but the character is echoed even if \fBpppoe-start\fR's standard output is not a tty. .TP .B PIDFILE A file in which to write the process-ID of the pppoe-connect process (for example, \fB/var/run/pppoe.pid\fR). Two additional files ($PIDFILE.pppd and $PIDFILE.pppoe) hold the process-ID's of the \fBpppd\fR and \fBpppoe\fR processes, respectively. .TP .B SYNCHRONOUS An indication of whether or not to use synchronous PPP (\fByes\fR or \fBno\fR). Synchronous PPP is safe on Linux machines with the n_hdlc line discipline. (If you have a file called "n_hdlc.o" in your modules directory, you have the line discipline.) It is \fInot recommended\fR on other machines or on Linux machines without the n_hdlc line discipline due to some known and unsolveable race conditions in a user-mode client. .TP .B CLAMPMSS The value at which to "clamp" the advertised MSS for TCP sessions. The default of 1412 should be fine. .TP .B LCP_INTERVAL How often (in seconds) \fBpppd\fR sends out LCP echo-request packets. .TP .B LCP_FAILURE How many unanswered LCP echo-requests must occur before \fBpppd\fR concludes the link is dead. .TP .B PPPOE_TIMEOUT If this many seconds elapse without any activity seen by \fBpppoe\fR, then \fBpppoe\fR exits. .TP .B FIREWALL One of NONE, STANDALONE or MASQUERADE. If NONE, then \fBpppoe-connect\fR does not add any firewall rules. If STANDALONE, then it clears existing firewall rules and sets up basic rules for a standalone machine. If MASQUERADE, then it clears existing firewall rules and sets up basic rules for an Internet gateway. If you run services on your machine, these simple firewall scripts are inadequate; you'll have to make your own firewall rules and set FIREWALL to NONE. .TP .B PPPOE_EXTRA Any extra arguments to pass to \fBpppoe\fR .TP .B PPPD_EXTRA Any extra arguments to pass to \fBpppd\fR .TP .B LINUX_PLUGIN If non-blank, the full path of the Linux kernel-mode PPPoE plugin (typically \fB/etc/ppp/plugins/rp-pppoe.so\fR.) This forces \fBpppoe-connect\fR to use kernel-mode PPPoE on Linux 2.4.x systems. This code is experimental and unsupported. Use of the plugin causes \fBpppoe-connect\fR to ignore CLAMPMSS, PPPOE_EXTRA, SYNCHRONOUS and PPPOE_TIMEOUT. .P By using different configuration files with different PIDFILE settings, you can manage multiple PPPoE connections. Just specify the configuration file as an argument to \fBpppoe-start\fR and \fBpppoe-stop\fR. .SH SEE ALSO pppoe(8), pppoe-connect(8), pppoe-start(8), pppoe-stop(8), pppd(8), pppoe-setup(8), pppoe-wrapper(8) rp-pppoe-3.12/man/pppoe-sniff.80000644000076400007640000000522612620655111014421 0ustar dfsdfs.\" LIC: GPL .TH PPPOE-SNIFF 8 "3 July 2000" .\"" .UC 4 .SH NAME pppoe-sniff \- examine network for non-standard PPPoE frames .SH SYNOPSIS .B pppoe-sniff \fR[\fIoptions\fR] .SH DESCRIPTION \fBpppoe-sniff\fR listens for likely-looking PPPoE PADR and session frames and deduces extra options required for \fBpppoe(8)\fR to work. Some DSL providers seem to use non-standard frame types for PPPoE frames, and/or require a certain value in the Service-Name field. It is often easier to sniff those values from a machine which can successfully connect rather than try to pry them out of the DSL provider. To use \fBpppoe-sniff\fR, you need two computers, a DSL modem and an Ethernet hub (\fInot\fR an Ethernet switch.) If the DSL modem normally connects directly to your computer's Ethernet card, connect it to the "uplink" port on the Ethernet hub. Plug two computers into normal ports on the hub. On one computer, run whatever software the DSL provider gave you on whatever operating system the DSL provider supports. On the other computer, run Linux and log in as root. On the Linux machine, put the Ethernet interface into promiscuous mode and start \fBpppoe-sniff\fR. If the ethernet interface is \fIeth0\fR, for example, type these commands: .nf ifconfig eth0 promisc pppoe-sniff -I eth0 .fi On the other machine, start your DSL connection as usual. After a short time, \fBpppoe-sniff\fR should print recommendations for the value of \fBPPPOE_EXTRA\fR. Set this value in \fB/etc/ppp/pppoe.conf\fR. If \fBpppoe-sniff\fR indicates that something special is required in \fBPPPOE_EXTRA\fR, please e-mail this to \fBpppoe@roaringpenguin.com\fR along with the name of your ISP and the manufacturer and model number of your DSL modem. This information will be collated and provided on the PPPoE web page for users who do not have two computers. After \fBpppoe-sniff\fR finishes (or you stop it if it seems hung), remember to turn off promiscuous mode: .nf ifconfig eth0 -promisc .fi .SH OPTIONS .TP .B \-I \fIinterface\fR The \fB\-I\fR option specifies the Ethernet interface to use.

It operates as follows: .TP .B o First, \fIlinkname\fR is sanity-checked. Too-long names and names containing illegal characters are rejected. .TP .B o Second, \fBpppoe-wrapper\fR opens the file \fB/etc/ppp/rp-pppoe-gui/conf.\fR\fIlinkname\fR for reading. If that file does not contain the line: .nf NONROOT=OK .fi then \fBpppoe-wrapper\fR fails. .TP .B o Otherwise, \fBpppoe-wrapper\fR runs \fBpppoe-start\fR, \fBpppoe-stop\fR or \fBpppoe-status\fR with the above filename as its single argument. .SH AUTHOR \fBpppoe-wrapper\fR was written by Dianne Skoll .

tkpppoe - A GUI for managing PPPoE Connections

Introduction

TkPPPoE is a graphical user interface for managing PPPoE connections. It performs two different functions:
  • TkPPPoE lets you define connection properties. This step must be done as root.
  • TkPPPoE lets you start and stop PPPoE connections. This step may be done as a normal user, depending on how you configured the connection.

Defining Connections

To define connections, start TkPPPoE as root. You can do this from a terminal by typing tkpppoe, or from the KDE or GNOME menus by selecting Internet : TkPPPoE. The following window pops up:

Main Window

Because you have not yet defined any connections, the connection property window also pops up:

Connection Properties - Basic
You can pop up the connection property window at any time by clicking New Connection... You can edit the properties of an existing connection by selecting the connection's name and clicking Properties...

Basic Information

Let's fill in the basic information:
  • For Connection Name, enter a unique name for this connection. It can be anything you like, but must contain only letters, numbers, underscores or dashes. In particular, it can't contain spaces. If you have only one PPPoE connection, a good name is Default.
  • For User Name, enter the user name supplied by your ISP. Enter only the user name; do not enter an "@isp.com" part.
  • For Network, you may have to enter your ISP's domain name. (For example, isp.com.) Some DSL providers add this to your user name; others do not. You may have to experiment a bit. The two most likely choices are your ISP's domain name, or blank. Try both.
  • For Password, enter the password your ISP provided you with.

NIC and DNS

Click on the NIC and DNS tab:

Connection Properties - NIC and DNS

  • For Ethernet Interface, enter the Ethernet interface connected to the DSL modem. It is something like eth0 or eth1. Click on ... to browse a list of detected Ethernet interfaces.
  • For DNS Setup, you have three options:
    1. From Server means that the system will obtain DNS information from the PPPoE server. This is the correct choice for most ISPs.
    2. Specify means that you will enter the IP addresses of your DNS servers manually. In this case, enter the addresses in the Primary DNS and Secondary DNS entries.
    3. Do not Adjust means that you want RP-PPPoE to leave your DNS setup alone. Use this if you are running your own caching DNS server or know that you don't want the DNS setup touched.

Options

Click on the Options tab:

Connection Properties - Options

  • If you want ordinary users to be able to start and stop this connection, enable Allow use by non-root users. If you do not enable this, non-root users will be able to monitor the connection, but not control it.
  • If you want to use synchronous PPP, enable Use synchronous PPP. This is recommended as it conserves CPU usage, but may not work on some (misconfigured) Linux kernels.
  • For Firewalling, you have three options:
    1. Stand-Alone installs a simple firewall ruleset for stand-alone machines. Use this if you have only a single computer connected to the DSL modem.
    2. Masquerading installs a simple firewall ruleset for using your Linux computer as an Internet sharing device. If you have two Ethernet cards, you can connect one card to the DSL modem and the other to an internal LAN. The masquerading firewall ruleset lets internal machines share the DSL connection.
    3. None. If you already have your own firewall rules, or you wish to run servers on your machine, select None. This is not recommended unless you take steps to secure your machine, and know what you are doing.

Advanced

Click on the Advanced tab:

Connection Properties - Advanced

In most cases, you can leave AC-Name and Service-Name blank. In some cases, your ISP may require you to enter information in these fields; contact your ISP for more information.

Controlling Connections

For these examples, run tkpppoe as a normal user (not root). The main window appears like this:

Main Window - Non-root

  • To start a connection, press Start. The two LEDs flash red and grey. If the connection is established, they turn green.
  • To stop a connection, press Stop.

The two rectangles to the right of the connection name are the status LEDs. The top LED corresponds to transmitted data and the bottom to received. The LEDs are colored as follows:

  • Grey -- connection is not established.
  • Flashing red/grey -- connection is being started.
  • Green -- connection is up, but idle.
  • Yellow -- connection is up and data is being sent or received.
  • Red -- connection has been lost, but the system is trying to reestablish it.

When a connection is established, two graphs appear:

Main Window - Established Connection

The left (red) graph shows transmitted packets and the average transmission speed (in bits per second) over the sample time. The right (green) graph shows received packets.

Miscellaneous Information

  • The connection menu has an entry called User's Manual which will pop up this user manual (if you have Netscape installed.)
  • You can define multiple PPPoE connections, but you should not use more than one simultaneuously unless you feel comfortable editing scripts and setting up routing tables. By default, TkPPPoE tries to add a default route for connections. This does not work well with multiple simultaneous connections.
  • If you exit from TkPPPoE, connections which are up remain up. You have to explicitly stop connections if you want them terminated.
