AFAIK tcpwrappers refuse too.
but I somehow missed the no route to.. :)
and you're right! it needs some investigation:

1. ping to the host
2. traceroute to the host.

if you sporadically get the no route problem, it means you have ... a routing 
problem :)

after you finished up with it, you can continue and trouble shoot.
routing problem can be cause by your university/enterprise firewall too.


you can also investigate with tcpdump, which is a great sniffer.

Good luck!
