Remote access to display from linux to linux machines using xauth

[ashkash13]

Hi, I am new to this forum and pretty new to linux systems.

I need to be able to access the display on a linux machine remotely from another machine and I was instructed to use xauth to manipulate the authority files and to create my own authority file for the authentication. I am not too sure of how to use the xauth utility and its commands properly. When I run xauth, it uses /tmp/.gdm8VI5JV as its default authority file.

How should I proceed?

Never used xauth but do you mean something like x forwarding? Like log into serverB from serverA and when you type in xclock, it shows xclock from serverB?

If so, try "ssh -X <serverb>" when you're on serverA

Sorry, I should have been more detailed.

I'm working for someone at the moment and learning little bits of linux as I go along. We want to be able to set up a machine so that we can display some kind of internet browser in a type of kiosk mode (without the fullscreen) on the gdm login page.

I've been able to find a browser to do that but we cannot edit how the gdm login screen boots to include the browser. I was told to try to see if I could remotely access said machine to start the browser on the same display as the gdm login which happens to use display :0. When I tried experimenting with xclock first, it would not let me run it on the same display short of me using xhost + command. I was told to try to use the xauth application to create my own authority file and allow permission but I don't know how to do this. I've tried several different combinations I've found on other forums and none seem to have worked.

I'm open to any suggestions (include direct solutions to the problem without using xauth)
