ping / nslookup / host not working


Hi,

On a vBulletin forum that I use, the email notifications have been broken for some weeks. The tech guy has gone awol, and so I've volunteered to have a look. I'm not experienced in server administration, but I'm trusted by the site owners as I've been an admin to the forum before.

Domain: britishchineseonline.com
IP: 66.111.36.90

ping google.com returns unknown host.
nslookup google.com returns can't find google.com: No answer.
host google.com has no output.

I'm thinking the problem must be related to this. Please help!

> more /etc/resolv.conf

domain britishchineseonline.com
nameserver 212.67.202.2
nameserver 92.51.159.40

Thanks in advance.

j.

What do you see when you type:

netstat -nr

See if your routing looks normal. You should see your gateway IP with a "UG" flag.

Welcome to LQ

The dns server doesn't respond
Quote:
repo@cannabis:~$ nslookup

Default server: 212.67.202.2
Address: 212.67.202.2#53
> www.google.com
Server: 212.67.202.2

repo@cannabis:~$
I would suggest to use open dns
208.67.222.222 and 208.67.220.220

I think there's another site running on the box
Code:

66.111.36.90    britishchineseonline.co.uk britishchineseonline.co.uk
66.111.36.90    britishchineseonline.com britishchineseonline.com

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
