Error is "Opening password file failed"<br />
<br />
Here's what I have done:<br />
<br />
created a "teachers" group and made all teachers members<br />
logged in as root<br />
ran vncpasswd<br />
changed password<br />
executed #cp -R -p /root/.vnc /opt/ltsp/i386/root/ (folder is present etc)<br />
ran visudo<br />
added line "%teachers ALL=NOPASSWD:/usr/sbin/fl_teachertool"<br />
made sure X4_MODULE_02 = vnc was uncommented in lts.conf<br />
<br />
teachers still cannot control, broadcast, etc. same error<br />
<br />
As a shot in the dark, I tried the following:<br />
made the following changes in build_x4_cfg to reflect recommendations on<br />
fl_teachertool website:<br />
<br />
#if [ "$VNC_MODULE_LOADED" ]; then<br />
# echo ' Option "httpdir" "/usr/share/vnc/classes"'<br />
# echo ' Option "PasswordFile" "/root/.vnc/passwd"'<br />
# echo ' Option "rfbport" "5900"'<br />
# echo ' Option "usevnc"'<br />
#fi<br />
<br />
# commented out if statement above to try fl-teacher website config<br />
#=========================================<br />
# Added to enable Monitor/Control in Fl_TeacherTool<br />
Option "httpdir" "/usr/share/vnc/classes"<br />
Option "PasswordFile" "/root/.vnc/passwd"<br />
Option "rfbport" "5900"<br />
Option "usevnc"<br />
#=========================================<br />
<br />
Still same error<br />
<br />
I even tried to give the teachers group permissions to read/write /opt/ltsp/i386/root/.vnc folder and passwd file. This resulted in a new error "no password configured for VNC Auth".<br />
<br />
Suggestions?<br />
