From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (WinNT; U)

Description of problem:
When a remote SSH client logs into the host, the DISPLAY variable should be set to  

where display is some number greater than 10.
 client_ip_address is not properly set.  Instead, $DISPLAY is set to
where localhost is the word "localhost".

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. set ssh on the client to display remote X applications on local server
2. connect to server using ssh
3. echo $DISPLAY

Actual Results:  localhost:14.0

(14 may be some other number)

Expected Results:

where is the ip address of the remote machine
and 14 is the "display"

Additional info:

This is relvant if the remote machine is tunneling to the linux server, e.g. through some NAT. 

A simple work-around is to let the .cshrc replace localhost with the correct ip address, but this should not be necessary.

Comment 1 Tomas Mraz 2005-02-03 13:01:10 UTC
I don't understand why it should be a problem? The localhost on the
remote machine is the remote machine and the forwarding to the X
server is done through the ssh encrypted connection.
