    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
    root@media's password:
    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
    Trying 127.0.0.1...
    Connected to localhost.
    Escape character is '^]'.
    ^]
    telnet> quit
    Connection closed.
    [root@media root]#

    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.
