Is there a firewall on the Linux box blocking port 6000?

For the moment, that seems the best bet..

Either that, or the Linux box doesn't have the IP address 100.11.18.10

let me try to explain this from an example

let said you are running X on a Linux machine A
A ip address is 10.10.10.10

Your HP-UX is machine B (You can be on character base terminal or in an X Gui environment it does not matter)
B ip address is 10.10.10.22

On A machine (10.10.10.10) type
xhost +10.10.10.22

on B machine (10.10.10.22) type
export DISPLAY=10.10.10.10:1.0
xclock &

This should work,if you do not have firewall or network problems and you are using bash on machine A, this probably the case

On machine B adapt export syntax to the shell you are running.

Another thing you can do, assuming you use ssh configured to forward X11 (if not see the sshd_config file): ssh -X . This will forward X through your ssh connection and will set the DISPLAY variable automatically. It's a beautiful feature!

Checked all the issues long back.
1) NO firewall , also m/c listenin on 6000 port

# netstat -l
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 localhost:32768 *:* LISTEN
tcp 0 0 *:sunrpc *:* LISTEN
tcp 0 0 *:x11 *:* LISTEN
tcp 0 0 *:ssh *:* LISTEN
tcp 0 0 localhost:smtp *:* LISTEN
tcp 0 0 *:xfs *:* LISTEN
udp 0 0 *:xdmcp *:*
udp 0 0 *:sunrpc *:*
2)HOme variable set properly.

Hi,
this may not apply to you, but I have had the scenario where the default user on the system must xhost+ then su must also xhost before Xlib will allow connections to be sent in and out of the system.

eg:if I just su and try to issue xhost+ I get the same error that you do. But if I xhost as default user then su and xhost+, run my export and run the required XApp, I do not get any errors. Maybe you could try something similar??

Hope this helps

regards

Matt

Okay check this out.
I was takin a Xsession of linux machine using Xbrowser on a win2k m/c, so when i was doing export dsiplay on the hpux m/c , of whose i was tryin to export display for OVW, i should have given ip of win2k m/c with :2.0 whereas i was givin ip of the linux m/c, which was wrong.

Can i get more Xwindows sessions of the same linux machine using Xbrowser, now when i m tryin that it is just showing an display with mouse representin X symbol.

u check the firewall in the LINUX server by using #iptables -L

i think some firewall setting only refusing the connection
