Make sure that VNCserver package is already installed:
# rpm -qa | grep vnc-server
vnc-server-4.1.2-14.el5_6.6
If not installed:
Download the latest version of VNC server from this link:
http://www.realvnc.com/download/vnc/latest/
Note: Server Free Edition has no security feature available.
Install VNC server on your server:
# rpm -Uvh VNC-Server-5.2.0-Linux-x64.rpm
Modify the VNC config file:
# vi /etc/sysconfig/vncservers
Add these lines at the bottom:
VNCSERVERS="2:root"
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"
Set a password for VNC:
# vncpasswd
Password:
Verify:
Start a VNC server session just to generate the default config files:
# vncserver :1
Note: It's recommended to not run VNC server as root, as this will allow connected users to have root privileges once they connect via VNC.
Configure VNC to start an Xsession when connecting:
# vi ~/.vnc/xstartup
UN-hash these two lines:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
Start a VNC session on the machine:
# vncserver -kill :1
# vncserver :1
Now you can login from any machine (your Windows machine) using VNCviewer to access that remote server using port 5900 or 5901. make sure these port are not blocked by the firewall.
VNC Viewer can be downloaded from this link:
http://www.realvnc.com/download/viewer/
Note: If you close that vnc session without logout you can re-login again to the same used session,
but if you logout from that session you have to re-issue the previous two commands again on the server:
# vncserver -kill :1
# vncserver :1
or just do it in one command:
# service vncserver restart
To disable VNCserver and kill current connected VNC sessions:
# service vncserver stop
or use:
# vncserver -kill :1
I hope that was easy and clear.
