I have a small network with different boxes. The network connects to the INTERNET by a vigor 2200E router that acts as DHCP.

There are some boxes with win (98/me/xp) some boxes with linux Suse 9.2- Ubuntu- Debian - FC3.

While Suse, Ubuntu(debian) have no trouble to make the right internet connection, FC3 and Debian(kanotix) can't.

The trouble is in the file /etc/resolv.conf

There should be a search entry YOURPROVIDER.com
and
nameserver [ipadres]
nameserver [ipadres]

If you change the entry's all is well.

Obviously FC3 and Debian take as nameserver, the ipadres of the ROUTER.

In that way you never get an Internet connection......................

The strange thing is that the live-cd's from Ubuntu (the install also) and Kanotix and Knoppix (all debian) make the right connection.

Is this a script issue somewhere in the install, or just an installation error?

firstly i'd wonder why your router isn't providing DNS directly. if it can dish out DHCP, then it's not exactly much more to expect it to do DNS relaying for you. if that's not possible though, you should be able to prevent your dhcp client from replacing the contents of resolv.conf. if you are using dhcpcd then add a -R to the dhcpcd options. normally this is controlled via an option like DHCPARGS = "-R" in /etc/sysconfig/network-scripts/ifcfg-eth0 but to be honest it changes a lot, and i'm normally wrong!

Thanks for your reply.

The strange thing for me is the different behavior by different distro's.

When I look in the setup for the router, DNS addresses are set correct.

For now I have changed the attribute from the resolve.conf file.

I keep however wondering that one distro connects without problems and the other does not.
Even if they are from the same 'root' say Debian, they seem to have different approaches to connect to the router.

I'll carefully study the routers instructions if I did change something, but I doubt, since the last installs where within a period of 3 weeks and there where no troubles with the router, so I had no reason to change anything.......


Thanks anyway, I'll follow your suggestion and a view other things.

live cds will look for dhcp, make sure you have dhcp client running on your distros. If one distro gets the settings, then dhcp and dns are being given out. Check what services are running.

I think I'have found it.

In one of the configurations of the router are the following entries :

For NAT Usage
1 st ip address [ ip adres of the router]
1 st subnet mask 255.255.255.0

For Ip Routing Usage [ DISABLED/enabled]
2nd ip address [192.168.2.1]
2nd subnet mask 255.255.255.0

RIP Protocol [DISABLED/ 1 st Subnet/2nd Subnet]

I think RIP should give 1ST SUBNET
