The first question I have is did you set xhost to allow the other server in? Normally setting "xhost +" is not a good idea, it's a security hole, so I usually do "xhost servername" to allow it in, and when done I "xhost -servername" to remove it.

Barnard Subject: Some servers do not forward X11, but I do not know why. I do not have newsgroup access, so I cannot pose this question on comp.security.ssh. The mailing list archives do not appear to have a solution. Hopefully you can help me. I have two identical Sun Solaris 9 servers. Both are running OpenSsh version 4.2p1. Both have identical ssh_config and sshd_config files. One allows me to run X programs and they are displayed back on my desktop. The other one reports Error: Can't open display: What am I missing to force this server to set the DISPLAY variable so that X11 will be forwarded? As I say the ssh_config and sshd_config files are identical with a server that works, and in particular ssh_config: ForwardX11 yes and sshd_config: X11Forwarding yes X11UseLocalhost no +----------------------------------------------------------------------- + | Christopher L.
