<DIV> </DIV>
<DIV>I'm against a brick wall here. I have searched Google and the archive
for this mailing list until my eyes have become crossed. I have
the following LTSP problem that I am hoping someone can help me with.</DIV>
<DIV> </DIV>
<DIV>I have K12LTSP 4.1 up and running; 1 server and 3 workstations. All
workstations are coming up nicely and users can log in to GNOME desktops
fine. VNC is another story. The environment I am trying to create is
one in which the instructor can take over a students desktop when necessary
using VNC. Everything I have tried to get this working has resulted in
failure.</DIV>
<DIV> </DIV>
<DIV>VNC works when using the standard vncserver/vncviewer utils. I start
vncserver on one workstation then go to another and start vncviewer and am
presented with the standard Twm desktop.</DIV>
<DIV> </DIV>
<DIV>Next I tried using x0rfbserver. When I start x0rfbserver on the
server, it runs fine; no errors. I can then connect from a workstation to
the server using vncviewer and see/use the desktop on the server. When I
reverse this procedure (start x0rfbserver on a workstation and try to connect
from the server or another workstation) the RFB window appears but as soon as I
try to connect with vncviewer, x0rfbserver dies with the following
error:</DIV>
<DIV>X Error of failed request: BadAccess (attempt tpo access private resource
denied)</DIV>
<DIV>Major opcode of failed request: 144 (MIT-SHM)</DIV>
<DIV>Minor opcode of failed request: 1 (X_ShmAttach)</DIV>
<DIV>Serial number of failed request: 571</DIV>
<DIV>Current serial number in output stream: 582</DIV>
<DIV> </DIV>
<DIV>Google gave me a few returns on this but not being an X programmer, it was
foriegn to me. One result also said to try using x11vnc which I did.
This had the exact same results.</DIV>
<DIV> </DIV>
<DIV>Next came use of x0vncserver. No matter where I try to
start (using -log *:stdout:100) this I get the following:</DIV>
<DIV>main: XTest extgension present - version 2.2</DIV>
<DIV>VNCServerST: creating single-threaded server x0vncserver</DIV>
<DIV>VNCServerST: shutting down server x0vncserver</DIV>
<DIV>main: unable to bind listening socket: Address already in use (98)</DIV>
<DIV>~ImageCleanup called</DIV>
<DIV> </DIV>
<DIV>This same error occurs when I try to run x0vncserver on the server but with
the addition of one line:</DIV>
<DIV>~Image called - usingShm 1</DIV>
<DIV> </DIV>
<DIV>I run x0vncserver with -rfbport 5800 and it seems to start fine (main:
:Listening on port 5800) but any connection attempts from other workstations
(using vncviewer 192.168.0.254:#) are refused with the following error:</DIV>
<DIV> </DIV>
<DIV>vncviewer: ConnectToTcpAddr: connect: Connection refused</DIV>
<DIV>Unable to connect to VNC server</DIV>
<DIV> </DIV>
<DIV>So that is where I am. I help that can get me moving again is most
appreciated.</DIV>
