The offser here is 10 (just that I had two X running on the workstation), now
I have only one X running and I tried what you told me:
$ ssh root@media
Last login: Mon Aug 25 18:45:46 2003 from lab.pupeno.com
[root@media root]# xeyes
_X11TransSocketOpen: socket() failed for tcp
_X11TransSocketOpenCOTSClient: Unable to open socket for tcp
_X11TransOpen: transport open failed for tcp/localhost:10
Error: Can't open display: localhost:10.0
[root@media root]# telnet localhost 6010
Connected to localhost.
Escape character is '^]'.
so, the problem is not here...
One question, the port 6010 is open in B only to localhost, right ? because
nmap only shows port 6010 if I nmap localhost on B.

That didn't work either :(
Thank you very much.
