Summary says it all. VERY anoying!
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
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?
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"! ------------------------------------------ [gerald@dopefish gerald]$ ssh localhost Last login: Mon Oct 23 13:20:10 from localhost.localdomain You have mail.

Works now.
