It complain "Cannot connect to X > server ....." What else does it say? Exact error messages help. From the limited information you did supply, the only thing I can think of would be to make sure that the remote host can establish connections to the local host. In other words, make sure the local host isn't subject to any address translation (NAT). The approach you described, however, is suboptimal at best. First, you're using telnet--that can't be good. Second, "xhost +" effectively allows *any* host to display *anything* on your screen. That might be okay if you're on an isolated network, but is generally unacceptable on today's Internet. A better solution would be to use SSH and its TCP/X forwarding capabilities. A typical session would look like: localhost% ssh -X remotehost xterm If both the local and remote hosts are configured to do X forwarding, and the DISPLAY environment variable is set when you run ssh, it will set up a corresponding entry on the remote host. This allows for an encrypted tunnel to run your X clients through. My description of the ssh X forwarding method is overly simplistic. It is meant to give you a general idea of what can be done. If you want to use it, please read the ssh(1) and sshd(8) manual pages.
