I can't get X11 forwarding to work between Redhat 9 and Mac OS X.
The Mac box is my desktop box. The Redhat box is on a KVM switch in the
server room. SSH versions are:
On Rehat: OpenSSH_3.5p1, SSH protocols 1.5/2.0, OpenSSL 0x0090701f
On Mac OS X: OpenSSH_3.6.1p1+CAN-2004-0175, SSH protocols 1.5/2.0,
OpenSSL 0x0090707f
Connection transcript is as follows:
[jamesc@marvin jamesc]$ ssh -vv faap2@grumpy
