Xvnc auth errors

[James H. Cloos Jr.]

I just grabbed the current version from the main web site.
(vnc-3.3.3r2_x86_linux_2.0.tgz). When I try to use it I
get this in the log:

===============================================================================
AUDIT: Fri Jan 12 07:02:59 2001: 7356 Xvnc: client 1 rejected from local host
Xlib: connection to ":1.0" refused by server
Xlib: Client is not authorized to connect to Server
xrdb: Can't open display ':1'
===============================================================================

Each of the commands which failed to work are in the ~/.vnc/xstartup; the only
change I made from the default (so far) is the wm.

This took me some time to debug. The problem is that openssh w/ X forwarding
on sets not just DISPLAY but also XAUTHORITY as it uses /tmp/ssh-XXXXX/cookies
rather than ~/.Xauthority for its own DISPLAYs.

The fix is for vncserver to $ENV{XAUTHORITY} = $xauthorityFile; and possibly
also to delete $ENV{DISPLAY};.

Indeed. (This was discussed on this list a month or two back.)

Here's the patch we're shipping:
