Hi I want to connect my Unix machine (server) to another Unix Machine (client) in which the client has some pictures. I want to be able to view the pictures that are on the client from my server. Is this possible? I need to use an XWindow (X11) but I'm not sure how to go about it. The client already has the IP address of the server and I can ping the client no problem.

Thanks in advance for any help you can give me!

If you login via ssh(1), you should set the DISPLAY variable to your X server host (one with graphics).

You'll need to sort out access control, this may be trivial with shared home directory, or you might need to do something with xauth.

Reading through the docs, ssh used to have good explanation of best way to do this.

How do I set the DISPLAY variable to the host ? Access control is already configured. When I try and connect to the host it comes up with problems regarding DISPLAY

Not surprising as I didn't authorise anything. And actually :

oak:/var/log # netstat -tlp
Active Internet connections (only servers)

Shows my X server isn't actually listening on a network port, secure or what? So have to enable remote connections to Xorg, to get it to work; I'm sure there'll be docs somewhere

Do you need to run the image viewer on the client machine to view the photos? If not, why not get the two boxes connected via NFS and read the photos over the network, viewing them on a image viewer running on the server?

Peace...

If there's not too many files, you could also use "rsync -essh -ax /server/pictures /to/dir" to copy them over quickly, without having to configure much.

There's always new stuff to learn.

ssh -X remotehost
Password:
$ echo $DISPLAY
localhost:10.0
$ xterm

And a window just opened, without doing anything else. Clever ssh(1)!
