installed the system and rebooted. now there is no network connection. during install everythinig went fine, but after reboot i can't connect to the ftp servers, but I can ping the other machines on the network via IP but not via dns name.
So I guess it has something to do with the dns?

Are you using a static ip or dhcp?

ip's for DNS-servers are stored in /etc/resolv.conf

Other machines in your own network have to be added in /etc/hosts.

If /etc/resolv.conf doesn't exist, then open a new file using nano and add something like

Tried to ping 212.162.48.146 and go t a msg saying "network is unreachable" so I guess something isn't working

Although, I can ping my gateway.

you can ping your gateway, but is it added to your routing table?

Found the problem in the routing table, the gateway is set to 0.0.0.0.
How do I change this?

hehehe,
I was having a problem with the same thing on my small LAN at home, but quickly realized that you have to add the 'domain' quantifier to /etc/resolv.conf

syntax:
domain yourdomain.net
nameserver your.first.DNS.ip
nameserver your.second.DNS.ip

:wink:

'domain' isn't a required options

correct,

domain isn't a required parameter, however if you're running an ipmasqued router / gateway/ firewall / nameserver, it helps if you're trying to resolve an internal host w/o them all listed in /etc/hosts.

I suppose i was generalizing when i shouldn't have been :roll:
