    Running xapps over ssh?

    So I have to login to my home server from remote locations from time to time and I do this using SSH and usually Putty for Windows unless I am on a linux machine. Some of the items that I would like/need to run are X applications. I have X11 forwarding turned on on the server but yet I still get the following error whenever I attempt to run an application over ssh:

    Xlib: connection to "localhost:10.0" refused by server
    Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
    Error: Can't open display: localhost:10.0"
    Now if I enter this first:
    export DISPLAY=localhost:10.0 XAUTHORITY=~/.Xauthority

    I get this error:
    X connection to localhost:10.0 broken (explicit kill or server shutdown).
    I have tried googling this but I haven't found anything useful. Anyone run into this and have you been able to fix it?

    Do you have both of these?
    • -X (capital! X) on the putty command line, and
    • X11Forwarding yes in file /etc/ssh/sshd_config on the server

    I can actually get it working if I run the xapp through ssh from any of my linux boxes or laptops, but I am not able to do this from a Windows XP machine using Putty. I do have X11 forwarding enabled in Putty but it's still a no go.

    Anyone have any other suggestions? Any other WinXP software that you would recommend that I could use?

    It says you are using display :10.0...have you tried specifying the display as :0 ?

    This may be a silly question, but have you installed anything on the windows XP box to act as an X server (I may mean client, I always get them confused for X).

    You can't just run X based programs over a ssh connection from a Windows box, you have to install something like cygwin first. There may be alternatives, but I've used cygwin with much success.

    Let us know how you get on,

    To be good, you must first be bad. "Newbie" is a rank, not a slight.
