When using Red Hat built openssh-server-3.9p1-8.RHEL4.17.1,
X forwarding is breaking when "X11UseLocalhost no" is added
to configuration file /etc/ssh/sshd_config.  Following is an
example.

  thishost$ ssh -Y thathost.pppl.gov
  thathost$ xclock
  Error: Can't open display: thathost.pppl.gov:13.0

Command xauth -list does show the above display name. 


Does "thathost.pppl.gov" resolve to the correct IP address?  Are there
any iptables rules that would apply to that connection?  If you try to
connect to the port with telnet (ie "telnet thathost.pppl.gov 6013" in
this example) what error does it give?

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
