Interesting DNS problem:
hout0101@monitoring:~$ getent hosts
hout0101@monitoring:~$ telnet 80
telnet: Name or service not known Unknown host
Found out after serious searching that this was caused by the /etc/resolv.conf line:
options rotate
Of the 3 available nameservers, numbers 2 and 3 decided to negatively cache for good reasons earlier. Options rotate counts per program which means the impact isn't that big for short-lived programs. I guess telnet does a query before querying the nameserver for the needed address to connect to.
