-pppoe: a PPP-over-Ethernet redirector for pppd
-Copyright (C) 2001 Roaring Penguin Software Inc.
-
-Much inspiration from an earlier client by Luke Stras.
-
-The MSS clamping was inspired by mssclampfw by Marc Boucher <marc@mbsi.ca>
-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
-ADSL 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. I have access only
- to FreeBSD. In general, I can't answer questions about the *BSD's
- as well as I can about Linux.
-
-
-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
-ADSL 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

-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. This should make it independent of locale, I hope!
-
-- Added "-k" and "-d" options to pppoe.
-
-Changes from Version 1.9 to 2.0:
-
-- Addition of pppoe-server
-
-- Massive internal code restructuring
-
-- Zealous bounds-checking everywhere.
-
-- adsl-setup now quotes user name and password in /etc/ppp/pap-secrets.
-
-- Ported to OpenBSD, FreeBSD and NetBSD, courtesy of Geoff Mottram
- and Yannis Sismanis.
-
-- Rearranged adsl-* shell scripts, courtesy of Heiko Schlittermann.
-
-- Fixed bug in which Host-Uniq did not work if access concentrator sent
- a cookie.
-
-- Addition of SuSE-specific "init" script, courtesy of Gary Cameron.
-
-Changes from Version 1.8 to 1.9:
-
-- Added some more documentation to HOW-TO-CONNECT
-
-- Demand-dialling option now works correctly
-
-- SIGHUP terminates pppoe after sending a PADT to the access concentrator
-
-- Minor cleanups to connection shell scripts
-
-Changes from Version 1.7 to 1.8:
-
-- Added demand-dialling option
-
-- Clarified HOW-TO-CONNECT
-
-- Added adsl-status script
-
-- Added "restart" and "status" options to Red Hat /etc/rc.d/init.d/adsl script
-
-- Made adsl-setup check for existence of pppd
-
-- Wildcarded external interface in firewall rules
-
-- Made pppoe send a PADT frame if connection is terminated

-This package lets you connect a Linux machine to Sympatico HSE or Magma's
-high-speed service using a Nortel 1-meg modem.
-
-Follow these steps and you should have your high-speed 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:
-
- adsl-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
-ADSL 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 ADSL 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/adsl. To bring up the connection
-at boot time, just type this command as root:
-
- chkconfig --add adsl
-
-On non-Red-Hat systems, add this line to the end
-of /etc/rc.d/rc.local:
-
- /usr/sbin/adsl-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 ADSL link
-------------------------------------
-
-As root, bring up the link by typing: adsl-start
-As root, bring down the link by typing: adsl-stop
-
-That's it!

-
-PROBLEMS! DAVE, 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
-
-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.
-

-If you are completely unable to connect, run the adsl-start script in
-debugging mode. If you are using bash as your shell (if you don't
-know what your shell is, it's probably bash), type this:
-
- DEBUG=1 adsl-start
-
-In tcsh or csh, use:
-
- setenv DEBUG 1; adsl-start
-
-Then follow the instructions to mail the debugging file to me. PLEASE
-DON'T DO THIS until you have exhausted all other avenues; rp-pppoe is
-free software and it costs me time and money to help people with
-problems. While I don't mind doing this, I do mind it if you don't
-make an effort to fix the problem yourself first.
-
-WARNING: If you run adsl-start in debugging mode and you manage to
-connect, your connection will be extremely slow and huge amounts of
-data will quickly fill your /tmp directory. Do not use debugging mode
-unless you really cannot get your connection to work.
-
-Be aware that debugging mode produces hex dumps which potentially reveal
-your user name and password. If the debugging output includes packets
-labeled "PPPOE Session", you may wish to remove these packets from the
-dump before mailing it to me.

-RP-PPPoE now supports kernel-mode PPPoE on Linux kernels 2.4.x. However,
-the default "./go" build procedure does not make kernel-mode support.
-
-Here's what you need to do:
-
-1) Download Michal Ostrowski's patched version of pppd which supports
-a PPPoE plugin. The latest version as of this writing is
-at http://www.math.uwaterloo.ca/~mostrows/ in

-3) In the rp-pppoe directory, change to src/ and type:
-
- ./configure --enable-plugin=/path/to/ppp-tree
-
-Here, /path/to/ppp-tree is where you unpacked the pppd software. It

-4) Type make; make install
-
-5) Edit /etc/ppp/pppoe.conf to include this line:
-
- LINUX_PLUGIN=/etc/ppp/plugins/rp-pppoe.so

- GNU GENERAL PUBLIC LICENSE
- Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.
- 675 Mass Ave, Cambridge, MA 02139, USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- 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.
-
- <one line to give the program's name and a brief idea of what it does.>

-<h1>tkpppoe - A GUI for managing PPPoE Connections</h1>
-</center>
-
-<h1>Introduction</h1>
-
-TkPPPoE is a graphical user interface for managing PPPoE connections. It
-performs two different functions:
-<ul>
-<li>TkPPPoE lets you <em>define</em> connection properties. This step must
-be done as root.
-<li>TkPPPoE lets you <em>start and stop</em> PPPoE connections. This step
-may be done as a normal user, depending on how you configured the connection.
-</ul>
-
-<h1>Defining Connections</h1>
-
-To define connections, start TkPPPoE as root. You can do this from
-a terminal by typing <code>tkpppoe</code>, or from the KDE or GNOME menus
-by selecting <b>Internet : TkPPPoE</b>. The following window pops up:
-
-<p>
-<center><img src="mainwin.png" width="361" height="73" alt="Main Window">
-</center>
-
-<p>
-Because you have not yet defined any connections, the connection property
-window also pops up:
-
-<p>
-<center><img src="props-basic.png" width="440" height="259" alt="Connection Properties - Basic">
-</center>
-
-You can pop up the connection property window at any time by clicking
-<b>New Connection...</b> You can edit the properties of an existing
-connection by selecting the connection's name and clicking
-<b>Properties...</b>
-<h4>Basic Information</h4>
-
-Let's fill in the basic information:
-<ul>
-<li>For <b>Connection Name</b>, 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 <b>Default</b>.
-<li>For <b>User Name</b>, enter the user name supplied by your ISP. Enter
-only the user name; do not enter an "@isp.com" part.
-<li>For <b>Network</b>, you may have to enter your ISP's domain name.
-(For example, <b>isp.com</b>.) 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.
-<li>For <b>Password</b>, enter the password your ISP provided you with.
-</ul>
-
-<h4>NIC and DNS</h4>
-Click on the <b>NIC and DNS</b> tab:
-
-<p>
-<center><img src="props-nic.png" width="440" height="259" alt="Connection Properties - NIC and DNS"></center>
-<p>
-<ul>
-<li>For <b>Ethernet Interface</b>, enter the Ethernet interface connected
-to the DSL modem. It is something like <b>eth0</b> or <b>eth1</b>. Click
-on <b>...</b> to browse a list of detected Ethernet interfaces.
-<li>For <b>DNS Setup</b>, you have three options:
-<ol>
-<li><b>From Server</b> means that the system will obtain DNS information from
-the PPPoE server. This is the correct choice for most ISPs.
-<li><b>Specify</b> means that you will enter the IP addresses of your DNS
-servers manually. In this case, enter the addresses in the <b>Primary DNS</b>
-and <b>Secondary DNS</b> entries.
-<li><b>Do not Adjust</b> 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.
-</ol>
-</ul>
-
-<h4>Options</h4>
-Click on the <b>Options</b> tab:
-
-<p>
-<center><img src="props-options.png" width="440" height="259" alt="Connection Properties - Options"></center>
-<p>
-<ul>
-<li>If you want ordinary users to be able to start and stop this connection,
-enable <b>Allow use by non-root users</b>. If you do not enable this,
-non-root users will be able to monitor the connection, but not control it.
-<li>If you want to use synchronous PPP, enable <b>Use synchronous PPP</b>.
-This is recommended as it conserves CPU usage, but may not work on some
-(misconfigured) Linux kernels.
-<li>For <b>Firewalling</b>, you have three options:
-<ol>
-<li><b>Stand-Alone</b> installs a simple firewall ruleset for stand-alone
-machines. Use this if you have only a single computer connected to the DSL
-modem.
-<li><b>Masquerading</b> 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.
-<li><b>None</b>. If you already have your own firewall rules, or you wish
-to run servers on your machine, select None. This is <em>not recommended</em>
-unless you take steps to secure your machine, and know what you are doing.
-</ol>
-</ul>
-
-<h4>Advanced</h4>
-Click on the <b>Advanced</b> tab:
-
-<p>
-<center><img src="props-advanced.png" width="440" height="259" alt="Connection Properties - Advanced"></center>
-<p>
-
-In most cases, you can leave <b>AC-Name</b> and <b>Service-Name</b> blank.
-In some cases, your ISP may require you to enter information in these fields;
-contact your ISP for more information.
-
-<h1>Controlling Connections</h1>
-For these examples, run <code>tkpppoe</code> as a normal user (not root).
-The main window appears like this:
-
-<p>
-<center><img src="mainwin-nonroot.png" width="206" height="73" alt="Main Window - Non-root">
-</center>
-<p>
-<ul>
-<li>To start a connection, press <b>Start</b>. The two LEDs flash red
-and grey. If the connection is established, they turn green.
-<li>To stop a connection, press <b>Stop</b>.
-</ul>
-
-<p>The two rectangles to the right of the connection name are the
-<em>status LEDs</em>. The top LED corresponds to transmitted data and
-the bottom to received. The LEDs are colored as follows:
-<ul>
-<li>Grey -- connection is not established.
-<li>Flashing red/grey -- connection is being started.
-<li>Green -- connection is up, but idle.
-<li>Yellow -- connection is up and data is being sent or received.
-<li>Red -- connection has been lost, but the system is trying to reestablish it.
-</ul>
-
-<p>
-When a connection is established, two graphs appear:
-
-<p>
-<center><img src="mainwin-busy.png" width="206" height="73" alt="Main Window - Established Connection">
-</center>
-<p>
-
-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.
-
-<h1>Miscellaneous Information</h1>
-<ul>
-<li>The connection menu has an entry called <b>User's Manual</b> which
-will pop up this user manual (if you have Netscape installed.)
-<li>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.
-<li>If you exit from TkPPPoE, connections which are up remain up. You
-have to explicitly stop connections if you want them terminated.
-</ul>

-.SH NAME
-adsl-connect \- Shell script to manage a PPPoE link
-
-.SH SYNOPSIS
-.B adsl-connect \fR[\fIconfig_file\fR]
-.P
-.B adsl-connect \fR\fIinterface user\fR [\fIconfig_file\fR]
-
-
-.SH DESCRIPTION
-\fBadsl-connect\fR is a shell script which manages an ADSL connection
-using the Roaring Penguin user-space PPPoE client. 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 \fBadsl-connect\fR
-directly. Instead, use \fBadsl-start\fR to bring up the ADSL connection.
-.P
-\fBadsl-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 \fBadsl-connect\fR re-establishes the connection. In addition,
-each time the connection is dropped or cannot be established,
-\fBadsl-connect\fR executes the script \fB/etc/ppp/adsl-lost\fR if it
-exists and is executable.
-
-.P
-The shell script \fBadsl-stop\fR causes \fBadsl-connect\fR to break out
-of its loop, bring the connection down, and exit.
-
-.SH TECHNICAL DETAILS
-\fBadsl-connect\fR uses the following shell variables from the
-configuration file:
-
-.TP
-.B ETH
-The Ethernet interface connected to the ADSL modem (for example, eth0).
-
-.TP
-.B USER
-The ADSL user-id (for example, b1xxnxnx@sympatico.ca).
-
-.TP
-.B PIDFILE
-A file in which to write the process-ID of the adsl-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. Just specify the
-configuration file as an argument to \fBadsl-start\fR and
-\fBadsl-stop\fR.

-.UC 4
-.SH NAME
-pppoe-relay \- user-space PPPoE relay agent.
-.SH SYNOPSIS
-.B pppoe-relay \fR[\fIoptions\fR]
-
-.SH DESCRIPTION
-\fBpppoe-relay\fR is a user-space relay agent for PPPoE
-(Point-to-Point Protocol over Ethernet) for Linux. \fBpppoe-relay\fR
-works in concert with the \fBpppoe\fR client and \fBpppoe-server\fR
-server. 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.

-
-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

-.SH SYNOPSIS
-.B pppoe-server \fR[\fIoptions\fR]
-
-.SH DESCRIPTION
-\fBpppoe-server\fR is a user-space server for PPPoE (Point-to-Point Protocol
-over Ethernet) for Linux and other UNIX systems. \fBpppoe-server\fR works in
-concert with the \fBpppoe\fR client to respond to PPPoE discovery packets
-and set up PPPoE sessions.
-
-.SH OPTIONS
-.TP
-.B \-F
-The \fB\-F\fR option causes \fBpppoe-server\fR not to fork and become a
-daemon. 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 should \fInot\fR be configured to have
-an IP address.
-
-.TP
-.B \-T \fItimeout\fR
-This option is passed directly to \fBpppoe\fR; see \fBpppoe\fR(8) for
-details.
-
-.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 \-m \fIMSS\fR
-This option is passed directly to \fBpppoe\fR; see \fBpppoe\fR(8) for
-details.
-
-.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 \-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.
-
-.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 \-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.
-It is \fInot\fR a high-performance server meant for production use.

-.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. Under Linux,
-it is typically \fIeth0\fR or \fIeth1\fR. The interface should be "up"
-and in promiscuous mode before you start \fBpppoe-sniff\fR.
-
-.TP
-.B \-V
-The \fB\-V\fR option causes \fBpppoe-sniff\fR to print its version number and
-exit.
-
-.SH BUGS
-\fBpppoe-sniff\fR only works on Linux.

-.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 ADSL 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.
-
-.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.

-.TH PPPOE.CONF 5 "21 February 2000"
-.UC 4
-.SH NAME
-pppoe.conf \- Configuration file used by \fBadsl-start\fR(8),
-\fBadsl-stop\fR(8), \fBadsl-status(8)\fR and \fBadsl-connect\fR(8).
-
-.SH DESCRIPTION
-\fB/etc/ppp/pppoe.conf\fR is a shell script which contains configuration
-information for Roaring Penguin's ADSL scripts. Note that \fBpppoe.conf\fR
-is used only by the various adsl-* 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 ADSL modem (for example, eth0).
-
-.TP
-.B USER
-The ADSL 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, \fBadsl-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 \fBadsl-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,
-\fBadsl-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) \fBadsl-start\fR should check to see if a new PPP
-interface has come up. If this is set to 0, the \fBadsl-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) \fBadsl-start\fR should wait for a new PPP interface
-to come up before concluding that \fBadsl-connect\fR has failed and killing
-the session.
-
-.TP
-.B PING
-A character which is echoed every \fBCONNECT_POLL\fR seconds while
-\fBadsl-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
-\fBadsl-start\fR is waiting for the PPP interface to come up. Similar
-to \fBPING\fR, but the character is echoed even if \fBadsl-start\fR's
-standard output is not a tty.
-
-.TP
-.B PIDFILE
-A file in which to write the process-ID of the adsl-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 \fBadsl-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
-\fBadsl-connect\fR to use kernel-mode PPPoE on Linux 2.4.x systems.
-This code is experimental and unsupported. Use of the plugin causes
-\fBadsl-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 \fBadsl-start\fR and \fBadsl-stop\fR.

-PPPoE (Point-to-Point Protocol over Ethernet) is a protocol used by
-many ADSL Internet Service Providers. Roaring Penguin has a free
-client for Linux systems to connect to PPPoE service providers.
-
-The client is a user-mode program and does not require any kernel
-modifications. It is fully compliant with RFC 2516, the official PPPoE
-specification.
