    Hello,
     
    I'm using ssh to do X11 forwarding over a gateway and it seems to work fine
    most of the time (xterms, xclocks). However, for some gui applications, I
    get the "X11 connection rejected because of wrong authentication." error. I
    have tried googling and tried different things but I can't seem to get it
    working. I was wondering if anyone knows what is going on. Thanks.
     
    Here's a log....During the session, I was able to bring an xterm and an
    xclock. But at the end of the session, I get the error when trying a run
    another gui application.
