I hate SSH/Xwindows, I always seem to have trouble with it too.
Besides the kill -HUP of the SSHD and "xhost +" do you have a
ls -log .X*
-rw------- 1 52 24 Jul 08:51 .Xauthority
file?
what's the output of the "set" command look like ?
besides the DISPLAY variable being set by "ssh -X" there should be
SSH_CLIENT='10.130.17.192 4904 22'
SSH_CONNECTION='10.130.17.192 4904 172.16.40.70 22'

here's the uncommented rows in my sshd (which is working ok)
egrep -v "^$|^#" /etc/ssh/sshd_config
Protocol 2
PermitRootLogin no
X11Forwarding yes
Subsystem sftp /usr/sbin/sftp-server

I assume you're got other XWindows clients working ok ?
I wonder what this line (above) means ?
debug1: Requesting X11 forwarding with authentication spoofing.

Are you running ssh server that comes with AIX?
I had problems with it, and I compiled OpenSSH on my system.

Try using "ssh -Y" instead of "ssh -X".

On my 5.3 box the /etc/ssh/sshd_config has:

XAuthLocation /usr/bin/X11/xauth
X11Forwarding yes

on the clients /etc/ssh/ssh_config has:

ForwardX11 yes
ForwardX11Trusted yes

With this setup I can tunnel X11 windows from
AIX 5.3 => AIX 5.2 => firewall => ISP/DSL => Mac OS X @ home
with a simple "ssh ". The DISPLAY variable
should not be set explicitly, but should look like "localhost:11.0" or so.

I use only standard OpenSSH/SSL from the IBM delivered media.

This looks to be the problem. You probably didn't install the file set
that contains xauth.

I thought so too, but xauth seems to be around;

$ which xauth
/usr/bin/X11/xauth
$

Under later Service Packs, we have found that the system loses 'xauth'.
I have had to explicitly point the sshd daemons at it via the line:

XAuthLocation /usr/bin/X11/xauth

in the /etc/ssh/sshd_config file. Once that is done and sshd is
restarted, then I can do XForwarding again.

Hmm, I just tried that and this time also restarted sshd by doing /etc/
rc.d/rc2.d/Ssshd stop/start (just to see if that makes a difference
compared to "stopsrc -s sshd" and "startsrc -s sshd"). Still no dice.

Another interesting update: I have no problems forwarding Xwindows
applications from my AIX 5.1 box.

Sorry for the double (or is it triple now?) but we are running openssh
(old version though but I did not install it):

[aixblade:/etc/ssh] ssh -V
OpenSSH_4.3p2, OpenSSL 0.9.7g 11 Apr 2005
[aixblade:/etc/ssh]

openssh is also being run in my 5.1 box, though even older:

$ ssh -V
OpenSSH_2.9.9p2, SSH protocols 1.5/2.0, OpenSSL 0x0090602f
$

4.3p2 is the version we run under 5.3, TL5, SP6.

When you cycle ssh, make explicitly sure it comes down 100%. For
example, I cannot run 'refresh -s sshd'. I have to explicitly 'stopsrc -
s sshd' and 'startsrc -s sshd'.

Also, if the problem persists, connect from the client with 'ssh -vvv'.
It is mostly gibberish, but sometimes it gives you an important clue as
to what the problem is.

I had the problem with just ONE customer. I simply reinstalled SSH not
using sshd included in the Linux Toolbox. I downloaded a new copy from
