PPPoE, Point-to-Point Protocol over Ethernet, is a network protocol for encapsulating Point-to-Point Protocol (["PPP"]) frames inside Ethernet frames. It is used mainly with ADSL services where individual users connect to the ADSL transceiver (modem) over Ethernet and in plain Metro Ethernet networks. (more on [wiki:Point-to-Point_Protocol_over_Ethernet Wikipedia]).
Installing Debian from the start a PPPoE enabled system
Debian Installer, starting with February 2007 supports installing a system via PPPoE and will configure the system accordingly. At the regular Debian Installer boot line just append modules=ppp-udeb (e.g.: type installgui modules=ppp-udeb to start a graphical installation via PPPoE).
More information in the Installation Guide, chapter [http://www.debian.org/releases/stable/i386/apds05.html Installing Debian GNU/Linux using PPP over Ethernet (PPPoE)].
How to enable PPPoE for an already installed system
In order to make PPPoE run on a Debian station you should follow the following steps:
- install a Linux kernel which has:
- ppp and pppoe support enabled (module or built-in). Kernels compiled by Debian have them.
- Ethernet driver for the interface on which you expect to connect using PPPoE
Run pppoeconf to generate and/or modifie /etc/ppp/peers/dsl-provider, /etc/ppp/*ap-secrets files and /etc/network/interfaces. ?BR It is best, in most cases, to keep the suggested answers
auto eth0 iface eth0 inet manual auto dsl-provider iface dsl-provider inet ppp pre-up /sbin/ifconfig eth0 up provider dsl-provider
PPPoE with kernelspace pppoe driver
pppoeconf try to load pppoe kernel module (modprobe -q pppoe). If there is a file /proc/net/pppoe, configuration will be in "kernel_mode". It's the case for a large majority of users because standard Debian installation have a kernel with pppoe compiled in module.
plugin rp-pppoe.so eth0
Documentation on how to use the kernel module without rp-pppoe can be found at [http://sysinf0.klabs.be/usr/share/doc/ppp/examples/peers-pppoe?dist=etch /usr/share/doc/ppp/examples/peers-pppoe].
PPPoE with userspace pppoe driver
Alternatively, user-space agent pppoe can be used.
pty "pppoe -I eth0 -T 80 -m 1452"
- If the name server information is not taken from the pppoe data, you will have to insert yourself that data in /etc/resolv.conf
