Remote X through SSH

[`danny]

I recently have gotten into Linux and have installed Fedora 8 on my laptop and Fedora 9 on my workstation that sits at home. I want to be able to access my workstation at home via a gui that is forwarded through ssh. I have tried the command ssh -Y root@ipaddy.com and can login in but do not know what to do after that to get a gui. Any help would be greatly appreciated.

Thanks,

Dan

ssh -X user@host appname

check the manpage for more info

Yup. Just be sure that your sshd configuration supports it.

Once you're logged in, just run a command that ordinarily spawns a GUI (xpdf, etc) and it will appear on your local machine. Don't expect any great speed though.

Ok I am able to connect but I do not know how to spawn a GUI, xpdf does not work

 

[ha1f]

elaborate.

Well once I ssh to the machine via SSH I want to start a remote X session. I have tried gnome-session and that does nothing. Any help?

just run a command that normally has a gui window

you don't start an entire session like with remote desktop. You run a program and that program appears on the local X server.

Keep in mind that you have to run a local Xserver on your machine in order to tunnel remote X applications over SSH; in other words, you cannot just type xcalc in the console (the actual console not a window with a terminal in it) and expect it to show up on the screen.

Why not use VNC? On my gentoo box I have it set up so that I can type

# vnc-server

and it'll create a new fluxbox session for me to vnc into on port 5901.. I can do this as many times as I want on subsequent ports.. ie: typing `vnc-server` again starts a completely different session on port 5902..

To access them remotely I use SSH-Port-Forwarding.. for example:

# ssh scjudd@home -L 5901:localhost:5901

would map my laptop's 'local' port 5901 to my gentoo box's port 5901. I could then start up a VNC viewer and connect to localhost:5901 on my laptop and it would pop up my newly created gentoo vnc session.

To kill the sessions when I am finished with them (to save resources), I simply type:

# vnc-server -kill :1

or :2, :3, :4 accordingly.

I would look into this method. Check http://gentoo-wiki.com/VNC for more information.

I figured out that I had to enter ssh -X user@hostname.com in xterm and then type in gnome-session on there and it worked just fine.

If you have a windows box you can do this with the help of an app called Xming
