no Xauth data

[gaf-mNDKBlG2WHs at public.gmane.org (Jerry Feldman)]

I am using Fedora 9 on an IA64 workstation. When I ssh -X to any host=20
including localhost I receive the following message:
Warning: No xauth data; using fake authentication data for X11 forwarding=
=2E

I have looked at some of the blogs on this. I have changed my DIPLAY=20
environment variable from ":0.0" to "localhost:0.0" and to=20
<hostname>:0.0" with no change in the message.  Additionally, ssh takes=20
about 20 seconds from this host. When I ssh -X from our other servers=20
(RHEL 4.6 X86-64) the login takes about a second, including ssh from one =

of the others hosts to the IA64.
The public key authentication takes under 1 second, so all the delay=20
occurs after a successful login. Once logged in,X forwarding works fine. =

I have "ForwardX11Trusted yes" set in /etc/ssh_config.
