My testbed PC is: FreeBSD 4.8-STABLE XFree86 Version 4.3.0,1 from ports Project home: http://xf4vnc.sourceforge.net I am using the "BETA 4.3.0.100" version On the machine that you want to remotely admin: Install the port ports/net/tightvnc This will install the TightVNC server and viewer along with the utility "vncpasswd" which is the only part of the tightvnc port that we will really need at this point as this box is the one we connect to. You will also need TightVNC installed on the machine you are using to connect to the remote :-) Download the 2 files from: http://sourceforge.net/project/showfiles.php?group_id=48178&release_id=168607 dummy_drv.o-4.3.0 vnc.so-ix86-freebsd-4.3.0.100 chown root:wheel dummy_drv.o-4.3.0 vnc.so-ix86-freebsd-4.3.0.100 chmod 444 dummy_drv.o-4.3.0 vnc.so-ix86-freebsd-4.3.0.100 cp dummy_drv.o-4.3.0 /usr/X11R6/lib/modules/drivers/dummy_drv.o cp vnc.so-ix86-freebsd-4.3.0.100 /usr/X11R6/lib/modules/vnc.so cd /root mkdir .vnc chmod 700 .vnc vncpasswd (pick your vnc password) OK the xf4vnc drivers are installed and your vnc password is set in /root/.vnc/passwd Now we need to modify the /etc/X11/XF86Config on our remote cd /etc/X11 cp XF86Config XF86Config.bak vi XF86Config Here is my basic XF86Config: (My main changes are done inside comments like this) ####################### # start xf4vnc mod SCH Load "vnc" # end xf4vnc mod SCH ####################### Pay _attention_ to any references to "Identifer" amd "InputDevice" entries, in my config I am using: Section "ServerLayout" Identifier "X1" Screen 1 "Screen1" InputDevice "vncMouse" "ExtraPointer" InputDevice "vncKeyboard" "ExtraKeyboard" InputDevice "Mouse1" "CorePointer" InputDevice "Keyboard1" "CoreKeyboard" EndSection So Screen1 Mouse1 Keyboard1 etc... are the correct entries in my setup, you may have references to Screen0 Mouse0 Keyboard0 in your config, just make sure they are all correct and in sync with your ServerLayout section. ----------------------------------snip---------------------------------- # ********************************************************************** # Module section -- this section is used to specify # which dynamically loadable modules to load. # ********************************************************************** # Section "Module" # This loads the DBE extension module.

The /var/log/XFree86.0.log can be helpful in troubleshooting your setup, and there seems to be X posistioning data that is logged to the XFree logs by xf4vnc, so these log files may grow quite a bit. >From your workstation run the vncviewer application and enter the IP address or DNS name of the remote to be controlled, provide the password you created with vncpasswd, and away you go !
