This is the wrong venue for this but you can do one of 2 things:
- If you want to use user1's dot files as user2 you can set HOME=~user1. X
programs will look for authentication info in $HOME/.Xauthority or whatever
file is defined in with the XAUTHORITY environment variable. user2 will need
to have read access to the file whether setting HOME or XAUTHORITY.
- You can export the key and import it for the other user.
As user1 before su: xauth list $DISPLAY
As user2 after su: xauth add __cut_paste_of_last_command__
set DISPLAY to proper value for ssh tunnel,
such as setenv DISPLAY localhost:10
I would recommend going to www.openssh.com. Under resources on the main page
you can sign up for the OpenSSH mail lists, or search the mail list archives.

Subject: Re: which port is used when one sets DISPLAY=clienthost:0 ?
Thanks again Stuart. You are responsible of a greate improvement
of my understanding on that. Just a last question :-)
If i SSH from [EMAIL PROTECTED] to [EMAIL PROTECTED], and then `su user2`
inside B, the X forwarding is broken, even if i
setenv DISPLAY localhost:10 or wharever number.
This is the message:
X11 connection rejected because of wrong authentication.
X connection to localhost:10.0 broken (explicit kill or server shutdown).
Is it possible to be fixed? Like if user2 is root, i cannot
log in directy to it from SSH. All the best ...
