Red Hat Bugzilla – Bug 1031244
x11vnc failed to work after recent updates
Last modified: 2013-11-22 03:44:51 EST
Description of problem: x11vnc would disconnect the client after random period of time Version-Release number of selected component (if applicable): x11vnc 0.9.13-8.el6.x86_64.rpm How reproducible: Connect the remote CentOS 6 machine via ssh and tunnel the x11vnc to localhost. VNC client would be disconnected after tens of seconds. Tried three clients on Mac, all the same. SSH and tunneling worked just fine. Additional info: It worked well until the most recent update. Maybe the latest Xorg update broke the compatibility.
Please attach logs and some errors what you see. There was not x11vnc updates long time.
There is nothing extraordinary in stdout of x11vnc, message, or .xsession-errors. x11vnc just said the client was disconnected and the client was disconnected for no reason. It happened randomly; sometimes the session last few second or tens of seconds. I am sure ssh connection was good since regular VNC server worked fine. Actually, x11vnc worked just fine before a system update of some Xorg packages and few other components like kernel and Nvidia driver.
Really I have no idea how to debug it without any info. Could you please run x11vnc with -verbose key and then look at relevant messages at failure?
