Can some please help me restore my networking? I have a VPS CentOS 6.3. Few minutes ago it was working well, Except I couldn't connect to the Yum repository. So I thought I could change some settings in Hostname and DNS Client under webmins network configuration. I changed the nameserver IP order (8.8.8.8, 0.0.0.0, 66.215.210.17) and also I have removed routing and gateways IP (* more later). Now I can't connect from terminal.
Few minutes back (from terminal using putty):
# host 66.215.210.17
17.210.215.66.in-addr.arpa domain name pointer unknown.hostforweb.net.
Now (only from hosting VPS Java client console)
# host 66.215.210.17
Host 17.210.215.66.in-addr.arpa not found: 5(REFUSED)
I have removed routing and gateways IP, because the IP there was 17.210.215.66. I remember changing by myself from 0.0.0.0, earlier. Instead of putting back 0.0.0.0 I left it empty and applied the change. My Bad!
How can I reset it back?
