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 - -I have only tested compilation on 2.2-kernel machines. Make sure you have -"make", the C compiler and all development header files installed. - ------------------------------------------------------------------------------ -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 ADSL 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 "adsl-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: - - adsl-stop; adsl-start - -This should work around buggy routers which do not support Path MTU discovery. - ------------------------------------------------------------------------------ -J) Whenever I connect using ADSL, 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 adsl-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 ADSL 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 ADSL modem. You might want to add these lines in -adsl-connect: - - ifconfig ethx down - ifconfig ethx up mtu 1500 - -which should reset things to sane values. - -####################################################################### -# WHEN ALL ELSE FAILS: # -####################################################################### - -If you are completely unable to connect, run the adsl-start script in -debugging mode.

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. - - <one line to give the program's name and a brief idea of what it does.> - Copyright (C) 19yy <name of author> - - 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. - - <signature of Ty Coon>, 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs.

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.

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.
