In attempting to set up a VoIP server, I came across some interesting behavior from Ubuntu.

My VoIP account was assigned a unique hostname that I am to connect to, however, Ubuntu is unable to resolve it via any non-dns tools (asterisk and ping). If I plug the hostname into nslookup or dig, it resolves fine and if I ping the hostname on any windows server I have available, it also resolves fine.

The hostname in question is a public domain with a guid prepended to it as a subdomain.

My nsswitch.conf file has hosts: files dns (removing files didn't help)

resolv.conf has nameserver 8.8.8.8

hosts has (censored the ip and domain)

127.0.0.1       localhost
198.144.xxx.xxx *****.*****.me      *****

# 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
ff02::2 ip6-allrouters

None of the other similar issues had this happening with public domains so I am lost on what is going wrong here.

Any advice or help would be appreciated.

"None of the other similar issues had this happening with public domains..." So if you enter another public hostname, like example.com into your hosts file, it works? –  Mathias R. Jessen Dec 17 '12 at 7:31
    
I'm not quite sure what you mean. When I said that, I was referring to the fact that many other similar symptoms have appeared with other issues but they were all resulting from local domains within a network. But yes, I can ping example.com without entering it into my hosts file. –  Josh Mackey Dec 17 '12 at 8:13
    
Can you post the output of an nslookup command so we can see it is using the correct DNS servers. –  Lipongo Dec 26 '12 at 4:05
