Running Win2k and get error when I try to connect to host

This is the error message I get:

"Can't open display"

I've read all the help material, but I'm still a little stuck. I am running Xmanager inside a LAN and my internal LAN IP# is I'm confused about when to use XDM and when not to as well. I'm trying to connect to a Sun Ultra 60s machine. When running XStart w/ some config changes, it brings up the messages box, logs me in correctly, gets to the command prompt, and then stalls after this command:

"glsn23> /usr/bin/X11/xterm -ls -display"

and eventually (after several minutes) gives this error message:

"Error: Can't open display:"

I have also tried starting Xmanager, telnetting into the machine and running the command, but this is what the remote command prompt says:

glsn23> xterm -ls -display
Error: Can't open display: alpha:0
Error: Can't open display:
[1] + Exit 1 xterm -ls -display alpha:0

Thanks in advance for all your help and support! I love your product and hope to use it quite frequently in the future.

Re: Running Win2k and get error when I try to connect to host

It seems that your Sun is not located in your private local LAN.
In this case, xterm can't reach at your PC to connect to the Xmanager.
You can try "ping" program at the Sun server.

1. login on the Sun using telnet program.
2. run ping program as following.
# ping

If the ping can't reach at your PC, there is a firewall between your PC and Sun server.

To cope with a firewall environment, you can try SSH (Secure Shell) connection supported by Xstart or configure your firewall to remap some ports used by Xmanager. Please read FAQ page for firewall settings at:
