RE: Hp - linux X-Application
Hi,
Many thanks for your fast answer. Since we have got Tru64
Systems I did the following on that machine.
1. login on Tru64
2. xhost +
3. telnet hp0000
4. TERM=xterm(during logging)
5. setenv DISPLAY tru64:0
6. xclock
This worked beautifully. In our internal network we donot have No
Firewall.
When I execute the following command on tru64, I see the port number
6000
netsta -a|grep 6000
tcp 0 0 *.6000 *.*
LISTEN
When I execute the following command on hp after logging from tru64
via telnet
I get an error:
% X -query tru64
Fatal server error:
Cannot establish any listening sockets - Make sure an X server isn't
already running
Eventhough it gives error I can run xclock application.
If I do the above steps from Linux to hp
1.login on linux
2.xhost +
3.telnet hp0000
4.TERM=xterm
5.setenv DISPLAY linux:0
6.xclock
Then I get an Error : can not open Display: linux:0
netstat -a|grep 6000 gives only the user prompt back on linux which
is different on Tru64.How can I open this port
on linux just for a test? I get the same error as given above for "X
-query linux" command.
I think this is a problem on linux configuration.
Regards,
Kumar

Hi Padiyath,
Make sure you don't have a firewall in place on your desktop. If you
have the default FW, it is blocking tcp:6000. Take it down, at least
temporarily (iptables -F INPUT) and try again.
Also try 'X -query linuxxx', check if it shows things ok.
Good luck,
Andrei
