Question xterm -display remote:0.0 Can't open display - xterm from tru64 to debian 3.1


Hi,

I am trying to initiate a remote xterm from a Tru64 Digital Unix 5.0 machine to a HP thin client running debian 3.1 and are getting 'Can't Open display'.

I have rsh and rlogin setup and logging in without passwords with the same user and password on both machines (Had to add hosts to /etc/hosts.equiv to allow this).

I have a hostname for the thin client on the digital unix box called 'HPTC' which pings and is correct.

I have added the Tru64 box in xhost on the HP client by xhost +tru64 and have also tried opening full access to the xserver with xhost +

If I try this command from the digital unix box;
xterm -display HPTC:0.0
I get
Error: Can't open display:0.0

Unfortunately I get no messages appearing in /var/log/messages to give me any indication of what is wrong. I also can't find any useful log messages on the Tru64 machine in /var/adm

Can anyone suggest why my xterm is getting refused or other means of troubleshooting further?

Many thanks,
Brett

Did you check the man page of xauth?

It depends how your X server is set up, esp. the selected authentication. Most of times this will be MIT-MAGIC-COOKIE-1, so the contents of the xauth man page might help you.

Question

I have tried extracting and merging the magic cookie of the Thin client's xserver into the xauth of the unix machine exporting the display. The error message still doesn't change.

I don't think its an authentication problem from what I have read since I'm still getting 'Cant open display'. If it were an authentication problem I would expect to get errors along the lines of

Xlib: connection to "glenlivet.mfcf.uwaterloo.ca:0.0" refused by server
Xlib: Client is not authorized to connect to Server
X11 Toolkit Error : Can't open display: glenlivet.mfcf.uwaterloo.ca:0.0
Bailing out!

I got this info from http://www.math.uwaterloo.ca/mfcf/fa...rm_display.faq

Im still battling on; any ideas would be greatly appreciated!
