Leonid,
Can you please do ssh -X to the machine, and then:
echo $DISPLAY
will give you something along the lines of "localhost:10.0"
[EMAIL PROTECTED] leonid $ echo $DISPLAY localhost:10.0 [EMAIL PROTECTED] leonid $
[EMAIL PROTECTED] leonid $ su -
Then take the number after the ':' (10 in this example) and add 6000 to it, and run telnet:
telnet localhost 6010

Replace the 6010 with the number you got (if it's different than 10). Let us all know what that gives you - the exact error message.
Can you also do
iptables -L -v -n
and mail the result? I'm assuming that the machine has iptables. The ipchains command is very similar.

My usual configuration of iptables allows all connections from localhost, but i removed all rules nevertheless for the testing, and no good.
My current guess is that you have ipchains/iptables rules on computer "A" that prevent local users from connecting to port 6010 from localhost, but that needs to be confirmed. What's baffeling to me is that the error message mentions the socket() function rather than the connect() function as I would expect in the case that my assumption is correct.
