was able to use ssh -x to call up a xterm from one server to the other. This is not correcting the problem that I'm having.

1) From a RHEL 5.0 server (192.168.222.51) I set the following:
export DISPLAY 192.168.222.50:0.0
2) Execute "xterm" and I get the following error:
xterm Xt error: Can't open display: 192.168.222.50:0.0
3) On the 192.168.222.50 server running Knoppix, I set the following:
xhost + <Enter>
access control disabled, clients can connect from any host
4) Execute "xterm" again from the RHEL server (192.168.222.51) and get the following error:
xterm Xt error: Can't open display: 192.168.222.50:0.0

It seems that I've got some type of firewall or something on the Knoppix system thats stopping these remote displays? Once again ssh is working between the two servers and I'm able to remote a display "xterm window" from the Knoppix server to the RedHat server.

I can't find how this was setup on Knoppix and this problem is also stopping me from not just remoting displays but using telnet.

Thanks,
John
