run this on the host:<br>

strace host <a href="http://www.google.com" target="_blank">www.google.com</a><br>

and scan the output.<br>

more efficient then guessing.<br>

Hi,<br>
<br>
I run an Ubuntu based VPS on Linode.<br>
I few hours ago the machine stopped resolving hostnames.<br>
I think it was after an "aptitude safe-upgrade" and a reboot, but I am<br>
not sure. Maybe was like this earlier.<br>
<br>
It takes ages to ssh to it, once I got to the machine I can ping IP<br>
addresses from it, but I cannot ping anything with a hostname.<br>
<br>
this is what I have in resolv.conf<br>
<br>
# cat /etc/resolv.conf<br>
<br></span>
domain <a href="http://members.linode.com" target="_blank">members.linode.com</a> <<a href="http://members.linode.com" target="_blank">http://members.linode.com</a>><br>
<br>
search <a href="http://members.linode.com" target="_blank">members.linode.com</a> <<a href="http://members.linode.com" target="_blank">http://members.linode.com</a>><span class=""><br>

nameserver 72.14.179.5<br>
<br>
nameserver 72.14.188.5<br>
<br>
options rotate<br>
<br>
<br>
I tried to replace the nameservers with others that are listed in<br>
another of my servers, but that did not make a change.<br>
<br>
How can I track down what has the server stopped resolving hostnames?<br>
<br>
Accessing the server via HTTP work as expected.<br>
