On of the most useful Feisty Fawn improvements is the integration of avahi. Using MDNS, you may address systems on the same network segment using a hostname instead of IP addresses. It’s dead simple: hostname.local:
shuerlimann@leni:~/cyt.ch/projects$ ping otherhost.local
PING otherhost.local (192.168.200.225) 56(84) bytes of data.
64 bytes from anon-client225.intern.example.com (192.168.200.225): icmp_seq=1 ttl=64 time=36.5 ms
Just make sure you allow incoming connections on UDP port 5353.
It looks like systems updated from Edgy Eft don’t get this feature by default. Please give me some hints how to do that if you know how to do it:-)
