Description Gerald Teschl 2000-10-19 14:59:15 UTC
Summary says it all. VERY anoying!

Comment 1 Leigh L. Klotz, Jr. 2000-10-20 01:09:47 UTC
Is it broken or is it just off by default (contrary to what the man pages says).
For the client, see /etc/ssh/ssh_config and note that "ForwardX11 yes" is 
commented out. For the server, note that /etc/ssh/sshd_config is similar.

Users can turn it on for the ssh client themselves in their ~/.ssh/config file, 
but the the sshd server it must be set by root in /etc/sshd/sshd_config

Comment 2 Nalin Dahyabhai 2000-10-20 20:34:06 UTC
I'm not able to reproduce this.  Are the machines on the client and server ends
of the connection both running the openssh-2.2.0 package, or is the server
running a different version?

Comment 3 Gerald Teschl 2000-10-23 11:37:07 UTC
Server/client are both RH7.0+updates.
Just found some time to investigate the problem further:

X11 forwarding is only broken if "UseLogin" is set to "yes"!
