evidently, there is no host '0' on your network - thus you have gotten
the only reasonable response possible.

if you are attempting to telnet to localhost port '0', you would
probably want to tell it 'telnet localhost 0' 

'man telnet'

though I am unaware of any service on port 0 that would respond

you might want to 'cat /etc/services' for a list of well known ports
