Re: [K12OSN] Re: fl_teachertool can't broadcast on k12 6



Something is wrong with vncreflector. When I try to start it, as directed in step #1 below, I see this in /var/log/messages:

Feb 19 08:02:34 k12ltsp xinetd[2818]: START: vnc-800x600x16 pid=4200 from=127.0.0.1
Feb 19 08:02:34 k12ltsp vncreflector: *** buffer overflow detected ***: vncreflector terminated
Feb 19 08:02:34 k12ltsp xinetd[2818]: EXIT: vnc-800x600x16 status=0 pid=4200 duration=0(sec)

Any idea what would cause a buffer overflow?

Yes, vnc-reflector-1.2.4-3.fc6 is installed, according to rpm.  Any
other ideas?  The error message suggests that the clients are refusing
the connection.  During the broadcast, a new login window and session
are created; perhaps the error is about establishing that vnc session to
the server rather than the vnc sessions to the clients?


Okay lets try this manually

1) first start the reflector
/usr/bin/vncreflector /etc/fl_teachertool/HOST_INFO_FILE &

2) start vncviewer for the teacher
/usr/bin/teachertool-vncviewer  localhost:99 &

3)start vncviewer for a student (from a client)
/usr/bin/teachertool-vncviewer -viewonly localhost:99 &

Let me know how it fails. Also check that you have the package
"vnc-ltsp-config" installed.
