[FreeNX-kNX] Cannot reconnect to session

[Michael Schmarck]

Hi.

I'm using NX Free Edition for Solaris 3.2.0-16 with
nxclient-3.2.0-13 and nxnode-3.2.0-14 (ie. the current
versions) on a Solaris 10 U5 Sparc system.

When there are no sessions running (at all or at
least for my user), I can start a NX session just fine.
Then, mostly in the evening, I shut down my NX
client (nx-common 3.2.0-1 & nxclient 3.2.0.13-2 on
an ArchLinux i686 system), which disconnects the
session.

Now, in the morning, I try to reconnect to the session.
But this fails.

Further down, you can see what's shown in the NX
log window (available after clicking on the "Details"
button). The connection window shows "The NX client
received an error from the server." And sometimes it
just says "NX".

In the log output below, you can find:

NX> 596 NX> 596 stderr: /usr/X/bin/xauth:  error in locking authority
file /export/home/mike/.nx/C-sys06-1014-4964A3AED3AE97F6DD0931AB76E0F441/authority

--> /usr/X/bin/xauth:  error in locking authority file [...]

I also get that, when I try to do a normal ssh login
with X11 forwarding enabled:

/usr/openwin/bin/xauth:  error in locking authority file
/export/home/mike/.Xauthority

I do *NOT* get this error, when I don't use NX!

If you look closely, you see that there's a different
path to the xauth utility. But that means nothing, because:

--($ ~)-- ls -laid /usr/openwin/bin/xauth /usr/X/bin/xauth /usr/openwin /usr/X
  99377 drwxr-xr-x    9 root     bin           512 Mrz  5  2005 /usr/openwin
  99407 -rwxr-xr-x    1 root     bin         45940 Jan 23  2005
/usr/openwin/bin/xauth
  53580 lrwxrwxrwx    1 root     root            9 Sep 17 15:16 /usr/X
-> ./openwin
  99407 -rwxr-xr-x    1 root     bin         45940 Jan 23  2005 /usr/X/bin/xauth

After doing a "nxserver --terminate mike && rm -rf ~mike/.Xauthority \
~mike/.Xauthority-c ~mike/.Xauthority-l ~mike/.nx", I can
do SSH logins without errors and also start a new NX session.

Does anyone maybe have an idea about what's
going on there?

Thanks a lot,
Michael
