Running UltraVNC repeater under Linux server

I am playing with remote support tools. There are a lot of good payed tools like TeamViewer, GoToMeeting and others but they are expensive. I found that UltraVNC has some tools like Single Click which can make it easy to provide remote support to your customers. Finally I ended by ChunkVNC which is basically UltraVNC but looking much more better.
There is a lot of tutorials on the Internet but they describe direct connection support. Which means at least one of the PC’s has to be accessible from the outside world. But I wanted to setup some server which I would connect to instead of connecting directly to customer’s PC. This server is called Repeater. UltraVNC has a repeater targeting Windows platform. But I have a Linux server and I wanted it to be running there. Fortunately a Linux port of the UltraVNC Repeater is also available. I have created a mirror of the latest version in case the original page won’t work.
The installation itself is not a big problem even though you have to compile the sources.

  1. Connect to the server using SSH
  2. Go to temp: cd /tmp/
  3. Download the sources: wget
  4. Extract them: tar zxvf  uvncrepeater.tar.gz
  5. Go to the sources directory: cd uvncrepeater/
  6. Compile the sources: make
  7. Copy repeater to sbin: cp repeater /usr/sbin/repeater
  8. Run it: /usr/sbin/repeater

If you want to make it running as a service you can use the following piece of code:

#! /bin/sh
# vnc: start/stop/restart the VNC repeater server
# chkconfig: 3 20 80
# description: VNC repeater server

vnc_start() {
if [ ! -f /etc/uvncrepeater.ini ]; then
echo "File /etc/uvncrepeater.ini does not exist. Aborting."
/usr/sbin/repeater 2>>/var/log/vnc.log &
pgrep repeater >/var/run/

vnc_stop() {
killall repeater
rm /var/run/

vnc_restart() {
if [ -r /var/run/ ]; then
kill `cat /var/run/`
echo "Killing repeater in the absence of /var/run/"
killall repeater
sleep 1

case "$1" in
echo "usage $0 start|stop|restart"

Take the code and save it into /etc/init.d/vnc file on the server. Then run the following commands to install it as a service:

  1. chmod +x /etc/init.d/vnc
  2. chkconfig –add vnc
  3. chkconfig –level 3 vnc on

  1. Thank you for your post. Was helpfull for me.

    But please add also information about adding user needed by vnc service – command is

    adduser –no-create-home –system uvncrep

    I’ve tested it on CentOS 6.4 x86_64 with

  2. If you are looking for a remote control program easy to use and do not give you any annoyance to the configuration of ports, firewalls and more use Ammyy Admin is quite useful.

  3. There is newer version available on UVNC website.
    Is there any way i can get package for arm base system ???
