Very odd partial networking issue with Ubuntu 8.10 guest OS

I've got an Ubuntu 8.10 server running with the Enhanced vmxnet nic.

The VMware tools are installed and am able to ping internal and external IPs (it's got a NAT), however.....I cannot resolve IPs at all.

The DNS server I'm using is working - have proven that. I've even tried changing to the google public dns server (8.8.8.8) which I can ping fine but they won't work either.

I have Apache and Sshd running - I can get to the ports but Apache won't serve pages and ssh won't prompt me for a login.

I've removed the original nic and added a new one - redone the static config for the new nic and get exactly the same. I've even recompiled and re-installed the VMware tools but no joy. Am running out of ideas now....

Does anyone have any suggestions as to what I can try next please as I'm running out of ideas....?

Maybe it is dns cache?

Flush DNS Cache in Ubuntu Using the following command

sudo /etc/init.d/nscd restart

how does your /etc/hosts file look like....

ncsd isn't installed.

hosts looks like:

127.0.0.1 localhost

10.x.x.1 servername.domain.tld servername

#194.169.254.10 gb.archive.ubuntu.com

#91.189.88.37 security.ubuntu.com

::1 localhost ip6-localhost ip6-loopback

fe00::0 ip6-localnet

ff00::0 ip6-mcastprefix

ff02::1 ip6-allnodes

ff02::2 ip6-allrouters

ff02::3 ip6-allhosts

I'd added the ubuntu references earlier to test if it was name resolution but then trying apt-get update it wouldn't pull down the headers....

Have sorted this now - kind of.

Ended up rolling the server back to a backup before the issue occured.
