establish connection
I establish the connection with a t-dsl excample. I suppose the network works properly like it is descriped in section network configuration.
For dns we use the same address for the client as we do for the router itself. The dns-address depends on you provider. But you can also use this one.
vi /etc/resolv.conf
nameserver 194.25.2.129
the address of the dns.

We check, if pppoe is installed :
rpm -qa rp-pppoe
rp-pppoe-3.2-3
If you get no answer, you have to install the package
( rpm -ivh rp-pppoe-3.2-3.rpm )
from your distribution-cd.
First we test the connection between the network interface card and the modem.
pppoe -I eth0 -A

If you get no answer, change the cable-position.
pppoe -T5 -I eth0 -D pppoe.log > /dev/null
makes an entry in actual folder in the file pppoe.log like this :

Update (23.07.02):
persist keeps connection alive, and holdoff 60 reconnects after 60 seconds of automatical disconnection. idle must be deactivated !

very important!
pppd pty "/usr/sbin/pppoe -I eth0"
establishes the connection to the internet.
./ifconfig
should deliver a connection named ppp0. This means, that the connection is established.
ping -c5 194.25.2.129
confirms the route to the dns
ping web.de
confirms functionality of the dns-connection.
for killing the connection just use
killall pppd
In new linux-Distribution you configure your internet-connection with adsl-setup. It is highly recommended, that you use such a configurationtool, if it is offered.
The following connection-script is only for old Distributions, which don't ship with a dsl-configuration-tool.
===> connection-skript (normaly not needed)
===> Masquerading - normally you go here !!!!
