I've run into the following issue recently following an intrusion in to my VPS:
Although resolv.conf is properly configured with the correct DNS servers the VPS can not resolve hosts.
- Ping the DNS Servers just fine
- I can ping based on IP
I can not:
- Resolve hostnames
- ping the hostname of the actual localhost / server.
I've tried looking into where the problem may lie but I see no rules, for instance, blocking outgoing DNS traffic.
hostname:/etc/network# nslookup google.com
;; connection timed out; no servers could be reached
I'm slowly running out of ideas on where to look.
Any ideas ?
Thanks in advance,
