Thank you for reply.
It is NOT doing good. Let me tell you little history. I had a shared hosting plan earlier with my hosting company. Than I purchased a VPS for me and wanted to bring my domain to this virtual server. That's where the problem is.
I am unable to update my nameservers to point it to towards my server. I am handling my domain from that shared hosting so far, that's why everything is fine apparently but i've received several emails since I setup my VPS with the following content:
Your hostname (vps.pakistanexaminer.com) could not be resolved to
an IP address. This means that /etc/hosts is not set up correctly,
and/or there is no dns entry for vps.pakistanexaminer.com. Please
be sure that the contents of /etc/hosts are configured correctly,
and also that there is a correct 'A' entry for the domain in the
Some or all of these problems can be caused by /etc/resolv.conf
being setup incorrectly. Please check that file if you believe
everything else is correct.
You may be able to automatically correct this problem by using the
'Add an A entry for your hostname' option under 'Dns Functions' in
your Web Host Manager.
