I'm having problems with ssh.com and X11 forwarding
ssh: SSH Secure Shell 3.2.0 (non-commercial version) on i686-pc-linux-gnu
I am in the process of testing some of my machines with CentOS 5
x86/x86_64 and have run into a bit of a snag. X11 Forwarding is not
working.
Any hints? I've checked the ssh config files and they seem to be
identical to the config files on our existing SuSE 10.0 machines which
are working. This is troubling indeed.
ssh -v and see what the ssh client complains about.
