Does your resolv.conf file really contain those x characters?

It shouldn't; it should contain valid IP#s of two nameservers your upstream provider has given you for recursive DNS lookups.

If it doesn't, but you've shown the x characters because you don't want us to see the real nameserver IP#s, well then, if you can't help me help you by giving me real nameservers to test, then I can't possibly help you.

here they are..


nameserver 127.0.0.1
nameserver 202.172.248.46
nameserver 202.172.248.4

 

[nobaloney]

nameserver 127.0.0.1
nameserver 202.172.248.46
nameserver 202.172.248.4

127.0.0.1 is your system. Is the bind daemon running on your server?

To check run (as any user, while logged in as shell) the following command (note the $ sign means you can be logged in as any user; you do NOT type the $ sign nor the space after it):

$ ps waux | grep named

and let us know the output.

Are those two other IP#s, 202.172.248.46 and 202.172.248.4, running on your server, or on some other server?

I can't reach either of those two IP#s, and it looks as if they're not live at all.

With none of the IP#s in resolv.conf able to resolve your DNS queuries, your system can't contact the outside world.

Make sure your DNS servers are *not* listed in your DA 'IP Management' section.
