Loose connection when i get a new IP from DHCP

Hi NG,

i'm client of Cablecom (a internet Provider in Switzerland). The Modem
through which I connect to the Internet implements a DHCP Server, from
which i also get the default gateway.
When I get a new IP on my linux box the network connection
disconnects. When I do a "rcnetwork restart" i get the new IP adress
and new gateway, but my connection to the Internet still doesn't work.
When i reboot my machine it reworks.
Does anyone have a idee which service has to be restartet, to get the
internet work?

Kind regards

Päng

Please read

It always helps if you provide some basic system information.

That info helps us to provide better examples/responses.

There are several "linuxes", about 190+ according to
http://www.distrowatch.com/stats.php

Always provide what distro and release level you are using
when you post questions (Pink Tie 10, Suse 9.0, Mandrake 9.2,...).

Different distros have different commands, files, and links to files,
pacakges and package/software managers.
Even happens between release levels of the same distribution.

If dhcp, which client (pump, dhcpcd, dhclient,...)

Oh sorry, I really forgotten to say which distribution i use:
I'm using SuSE Linux 8.1!

My dhcp client uses the following parameters (ps -ef):
/sbin/dhcpcd -D -N -Y -t 999999 -h <hostname> eth0

Hope this information helps!

If you do a man dhcpcd it will indicate that you can create an
exe script which executes when the ip address changes.
That file goes in /etc/dhcpc and has the name of the the nic. Example
/etc/dhcpc/dhcpcd-eth0.exe

Sorry, I have not used Suse, so I have no idea of what all to change where.

The script would get the new hostinfo with
. /etc/dhcpc/dhcpcd-eth0.info
then modify /etc/hosts, firewall rules, /etc/resolv.conf,
/etc/named.conf depending on if you use them or not.

I read in the man and i know that there is a possibility to attach a
script to dhcpc. My problem is, that I don't know what to do in this
script.
With my knowledge (that's not a lot), i think that if I got a new
gateway ip, this one should be used. But i seems not to work in the
way i'm thinking of :-(

What exactly do I have to do in this script?
