Hi,

I encountered some problems loging from a SUSE Linux pc onto a HP-UX server
and redirecting the DISPLAY to the Suse pc. Here is what I am doing (suse
and hpux stand for the names of the two boxes):

[suse]$ xhost + hpux
[suse]$ rlogin hpux
[hpux]$ export DISPLAY=suse:0.0
[hpux]$ xclock
Error: Can't open display: suse:0.0

- Networking works fine, both "ping suse" and "ping hpux" work.
- The Xserver listens to tcp port 6000, "ps -edaf | grep xdm" gives
root 6123 6113 2 11:41 tty7 00:00:07 /usr/X11R6/bin/X -br :0 vt7
-auth /var/lib/xdm/authdir/authfiles/A:0-N9wgXF - "netstat -ln" confirms
that:
tcp 0 0 0.0.0.0:6000 0.0.0.0:* LISTEN
tcp 0 0 :::6000 :::* LISTEN
- "ssh -X" is no alternatice as there is no reliable ssh available for the
(very old) HP-UX server.

I could not find any other configurations that should hinder the DISPLAY or
any advice what else to do.
Do you have any ideas what else I could try?

You have
DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="yes"
in /etc/sysconfig/displaymanager
right?

You could try logging in to another SUSE Linux machine and try to export the
DISPLAY to your own box to see how that goes. I tried and it worked for me.

Also, check the firewall stuff. From hpux, try "telnet susebox 6000"; you
should get a "Connected" response.

And use just "xhost +", while you test, to rule out DNS problems. You can
restrict aftewards.
