Odd network problem
This is my first post so please be gentle.
I have a Debian server on the internet and its an odd problem since a reboot.
First it wasn't reachable at all. Problem was there was no driver installed for the nics.
insmod e1000.ko did the trick
now i can ping it, ssh to it, and the websites are available again.
but when i want to ping a website (google) or another server, i get "ping: unknown host ***"
also "apt-get update" fails ("Could not resolve .....")
It's not behind a firewall at the moment, because it wasn't reachable behind it. While other server, which use the same firewall rule, were reachable. This is very strange imho.
Does somebody know anything i could check. Maybe a setting or driver.
I'm actually a noob when linux is involved.
