You probably need to do an 'xhost hpuxservername' on your Linux box.

# xhost hpux_server_name

or to allow all X connection to your box

# xhost +

[T G Manikandan]

if you are working on the linux machine directly.

First do a

#xhost +

from one of the terminals

then

connect into your hpux machine and
#export DISPLAY=:0.0

From you are using a x-windows software from a PC then your DISPLAY should be set to its ip.

xwindows connection to linux from PC.

do a xhost +

Then

connect to hpux
then

export DISPLAY=:0.0

Another solution would be to create a X tunnel using ssh when logging in from the Linux to the HP-UX environment. For this you would have to alter the sshd_config on the HP-UX server and run the ssh command with the -X option.

More info on this can be found on the openssh site or in the documents that come with ssh when installing it on linux.

Also worth noting is that if you are using recent Red Hat distro's port 6000 is disabled. This is required for this kind of thing to work.

If the above posts don't work for you, I would make sure that port 6000 is available.

It may help if you tell us, what distribution you are using on your linux server.

Some distributions start their X-server with the option '-nolisten tcp'. This prevent any connection to your X-server over the network. If this is the case, remove it and then the other comments about 'xhost' etc. will work.

Thanks,
My linux distribution is redhat 9.0.

Before the export display from my hpux 11.11 to my linux, i execute xhost + in my hpux and linux, the problem is present.

Any idea?
Thanks

Check the configured IP address on Linus, and the configured IP address on HPux.

Ping the destination IP, and ensure that it works.
Then do nslookup with the system name or alias, and then also with IP.
DO the same from HP to Linux.

I had ran across this problem, where the IP defined in the /etc/hosts was incorrect.

Hi,

may be there is a network pb. In some cases, depending on our network equipement (swicth/routeur/firewall) configuration we have to use ssh with X11 forwarding to have X11 working.

Hi Dav,


Pls check the ip address of Linux & HP both side & also resolve the same with nslookup command.If this works perfect then try to ping the linux server with HP server with large packet size,if reply is ok then , It shoud work.
