hi there,

beat me for it but do help, please, this problem is about a RedHat
machine... and yet, i *have* to solve it... :)

we cannot SSH XForward between a specific pair of hosts. The client
can XForward with other sshd's, but noone can XForward with that one
particular sshd in this configuration. I thus conclude: it must be
a server problem. smart me!

the configuration in /etc/ssh/sshd_config is correct. X11Forward is
set to Yes and X11DisplayOffset to 10, just like all my Debian
machines. it's got OpenSSH 2.5.2p2 running.

looking at the debug output from any client, i see the following
relevant info:

  debug1: channel 0: new [client-session]
  debug1: channel_new: 0
  debug1: send channel open 0
  debug1: Entering interactive session.
  debug1: client_init id 0 arg 0
  debug1: Requesting X11 forwarding with authentication spoofing.
  debug1: channel request 0: shell
  debug1: channel 0: open confirm rwindow 0 rmax 16384

so it looks like it's working, but then starting an X client in that
ssh session yields:

  Error: Can't open display: fluffy:12.0

(but after taking about 2 minutes...)

does anyone have any clues?

thanks!
