Network: PPP: Connecting with PPPoE
(last edit: 2001-04-12)
                   There is a realy good document op daemon news about PPPoe

Introduction
PPPoE means Point to Point Protocol Over Ethernet and is used by e.g. ADSL providers and
in my case by my cable provider Casame/Wanadoo . PPPoE has been part of PPP for a long time
and is therefor configured via '/etc/ppp.conf'. If you want to know more: click the above
link if you just want it to work read below:

Configuration
Make sure your kernel supports 'NETGRAPH' and the pseudo device tun:

options         NETGRAPH
options         NETGRAPH_PPP
options         NETGRAPH_PPPOE

pseudo-device   tun

If you don't know how to compile a kernel click here

Furthermore: make sure your networkcard to which the modem is connected is in your kernel
and is working.

If all the above works you can edit the '/etc/ppp/ppp.conf' file and make sure it looks 
something like this:

---
default:
 set device PPPoE:ed0
 set log Phase Chat LCP IPCP command
 set speed sync
 set ctsrts off
 set mru 1492
 set mtu 1492
 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0

 enable lqr
 add default HISADDR
 enable dns
 nat enable yes

wanadoo:
 set authname [your username here]@wanadoo
 set authkey [your password here]
---

You can start ppp via the command line as follows:

root@host:/#ppp -ddial wanadoo
Working in ddial mode
Using interface: tun0
root@host:/# ifconfig tun0
tun0: flags=8051 mtu 1492
        inet 213.17.84.237 --> 213.17.84.1 netmask 0xffffff00 
        Opened by PID 1159
 
The first ip address is your ip address the second of the first router/gateway.

The '-ddial' option means this:

man ppp

      -ddial
             This mode is equivalent to -auto mode except that ppp will bring
             the link back up any time it's dropped for any reason.
      -auto
             ppp opens the tun interface, configures it then goes into the
             background.  The link isn't brought up until outgoing data is de-
             tected on the tun interface at which point ppp attempts to bring
             up the link.  Packets received (including the first one) while
             ppp is trying to bring the link up will remain queued for a de-
             fault of 2 minutes.

rc.conf
Offcourse you want ppp to start when your machine starts, put these lines in your 
'/etc/rc.conf':

ppp_enable="YES"
ppp_mode="ddial"
ppp_profile="wanadoo"
