traceroute

[john gennard <joney@clara.co.uk>]

I still have problems trying to configure a home network. Thinking 
traceroute might shed some light on this, I ran the program and got 
the following error messages:-

a. From box 4 to 5 where ping works but not telnet

traceroute: warning: findsaddr: cannot open netlink socket:
	address family not supported by protocol

traceroute: warning: ip checksums disabled

b. From box 5 to 4 where both ping and telnet works

traceroute: warning: findsaddr: error sending netlink message:
	connection refused

traceroute: warning: ip checksums disabled


These messages don't help me at all - I don't understand them.
Would someone kindly explain what they mean and what if anything I 
can do to rectify matters.

grateful for assistance,

john.
