1. Installation of the software


2. Configure VNC password for the user(s)

  • Switch user to the user you want to use for VNC :
    • # su - vncuser1
NOTE: Replace 'vncuser1' with the correct username
  • Set the VNC password for the user :
  • $ vncpasswd
  • $ exit
  • Repeat for each VNC user as necessary


3. Configure resolution for the user(s)

  • Edit '/etc/sysconfig/vncservers' with your favorite editor
  • Append the following lines :
    • VNCSERVERS="1:vncuser1 2:vncuser2"
    • VNCSERVERARGS[1]="-geometry 1024x768"
    • VNCSERVERARGS[2]="-geometry 1024x768"
NOTE: Replace 'vncuser1' and 'vncuser2' with the correct usernames. You can add more users as needed. In addition, you can change the resolution value as needed.


4. Start the VNC server

  • Start the service :
    • # service vncserver start
  • Ensure service is started on reboots :
  • # chkconfig vncserver on


5. Configure the firewall

  • # iptables -I INPUT -m state --state NEW -p tcp --destination-port 5901 -j ACCEPT
  • # iptables -I INPUT -m state --state NEW -p tcp --destination-port 5902 -j ACCEPT
NOTE : Each user requires an additional firewall port opened starting at 5901. Because we added two users above, we need to open two ports.
  • # service iptables save
