Hiya folks,
I've been having an interesting issue with the free version of vncviewer (well,
the version bundled with Solaris 10, anyway...), and am wondering whether
there's a fix in the commercial version. What I'm seeing is 100% reproducible,
and goes like this:
In a labelled zone on Solaris 10 Trusted Extensions - classic sparse-root zone,
with /usr/bin/vncviewer mounted readonly over loopback:
* open a session onto a VNC server (I'm using the one built into Fedora 15 for
this, although it's not exclusively a Fedora problem; Ubuntu 10.10 exhibits it
too)
I get the usual start-up details:
# vncviewer 10.0.1.2:0
VNC Viewer Free Edition 4.1.3 for X - built Dec 3 2008 23:03:17

* now, open a terminal in the session, type something, highlight it, put it in
the copy buffer
* move pointer out of the window showing the VNC session, the window closes and
the following error pops up in the terminal used to launch vncviewer:
X Error of failed request: BadWindow (invalid Window parameter)
Major opcode of failed request: 18 (X_ChangeProperty)
Resource id in failed request: 0x41
Serial number of failed request:20318
Current serial number in output stream: 23019
Any ideas? I wonder whether "something unconventional" may be happening in
terms of vncviewer having its own cut / paste system rather than the one
provided by the X server; does cut / paste work OK between different VNC
sessions on a non label-aware system?
Cheers,
