You don't need to do anything with xhost _at_all_ on a properly setup box. I will call xauth for you. If the DISPLAY variable is not set, it is because the client/server is not setting it, and something want to use it on the server side. Make sure that you're client is asking for X-Forwarding. You can do this manually using -X to enable it, or doing it in /etc/ssh/ssh_config. This is best done on a server-by-server basis, since it can lessen your security to allow all servers to interact with your X server is not a good idea on untrusted hosts. You also need to make sure that X Forwarding is set on the server, by editing /etc/ssh/sshd_config, and setting these lines as so X11Forwarding yes X11DisplayOffset 10 Also note that if you're using private/public keys to authenticate, then features such as X-Forwarding can be disabled for various keys. To test it (if by now it doesn't work), start ssh with the -v flag. This will print out verbose messages (debugging really, however, there is a more detailed mode called debugging also). On the server, if you '/etc/init.d/ssh stop' the server, then run the server as 'sshd -Dd', you will get a one-time debugging run of the server. This will very likely give you the information you need to solve the problem. I suggest having a read of 'SSH: The Definitive Guide', published by O'Rielly. I found it very enlightening reading.
