I have Xubuntu 14.04 installed on my server.
network-manager is not installed. It seems to have lost its ability to resolve domains, and I'm not sure where to begin diagnosing the issue.
ping 220.127.116.11 pings normally.
ping google.com returns
ping: unknown host google.com.
I tried adding a DNS server to
/etc/network/interfaces/. Now it contains:
# interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.0.100 gateway 192.168.0.1 netmask 255.255.255.0 dns-nameservers 18.104.22.168 22.214.171.124
This didn't fix the problem, so I tried running:
hesse@galois:~$ sudo service networking restart stop: Job failed while stopping start: Job is already running: networking
reload but they didn't seem to do anything.
How do I diagnose the problem?
Note: It is a lot of work for me to restart the machine (I need to connect a keyboard and monitor to it), so please suggest solutions that don't require restarting if possible.
