Package: vncserver
Version: 3.3.7-12
Severity: grave
Justification: renders package unusable
Our development system runs debian testing; the developers normally log on
using VNC.
xinetd is set up with server vnc services (for various geometries); they run
Xvnc (Xrealvnc)
with the -query option so each connection gets its own gdm login).
However, since a (partial) dist-upgrade earlier today, this has ceased to
function - the
connection is terminated immediately. This happened _before_ doing the full
xorg upgrade
(the font server upgrade came in as a dependency of another package, and I'm
guessing it's
at fault). Completing the full dist-upgrade did not resolve the problem.
I did note that tightvncserver was removed during the upgrade, but since we
don't use that,
I didn't see it as a problem - if I had know that ALL vnc servers would break,
I would not
have upgraded (and again, the vnc breakage happened even before the
tightvncserver removal
was required by dist-upgrade).
What can I do to get VNC access working again? Or alternatively, what steps
can I take to
"dist-downgrade" to a _working_ setup?
We can (mostly) manage using plain old ssh connections, but it does have an
impact on
productivity.
++ Now I'll answer myself, because I found a solution while preparing this
report.
The cause of the problem is that Xvnc can't find some core things (rgb.txt and
the 'fixed'
font). These were relocated as part of the X11R7 upgrade. It's possible it
can no longer
talk to the new font server either (otherwise the relocations wouldn't matter
to it because
the font server would handle them). vncserver/vnc4server work around this by
passing -co
and -fp options to the Xnvcs they spawn. So the solution is to do the same in
/etc/inetd.conf
(or /etc/xinetd.d/myvncservice).
Instead of
/usr/bin/Xvnc -inetd -once -query my-x-host -geometry 1234x666 -depth 24
the command line needs to be (on one line)
/usr/bin/Xvnc -co /etc/X11/rgb -fp unix/:7100,<all other font paths separated
by commas> \
-inetd -once -query my-x-host -geometry 1234x666 -depth 24
(is there a cleaner way to do this, e.g. by putting those options in some
config file Xvnc
reads?)
README.debian should probably be adjusted accordingly (the instructions there
no longer
result in a working setup).
