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! - --- -David F. Skoll <dfs@roaringpenguin.com> | Roaring Penguin Software Inc. -http://www.roaringpenguin.com | Linux and UNIX Specialists - -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. - -####################################################################### -# WHEN ALL ELSE FAILS: # -####################################################################### - -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. |
