VNC (Virtual Network Computing<\/strong>\u00a0<\/strong>) is a graphical desktop sharing system that uses the Remote Frame Buffer protocol to remotely control another coumputer on a network.<\/p>\n

To run the VNC Server on CentOS, we have to install these required packages:<\/p>\n

Code:\u00a0[Select]<\/a><\/div>\n
yum groupinstall Desktop\nyum install tigervnc-server\nyum install xorg-x11-fonts-Type1\nyum install vnc<\/code><\/pre>\n
To start VNC Server on boot<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
chkconfig vncserver on<\/code><\/pre>\n
To setup users\u2019 VNC password:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
vncpasswd<\/code><\/pre>\n
Edit the \/etc\/sysconfig\/vncservers file:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
nano \/etc\/sysconfig\/vncservers<\/code><\/pre>\n
Add the following to the end of the file:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
VNCSERVERS=\"1:arbab\"\nVNCSERVERARGS[1]=\"-geometry 1024x600\"\n<\/code><\/pre>\n
The iptables rules need to be amended to open the VNC ports:
\n<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
iptables -I INPUT 5 -m state --state NEW -m tcp -p tcp -m multiport --dports 5901:5903,6001:6003 -j ACCEPT\nservice iptables save\nservice iptables restart\n<\/code><\/pre>\n
Restart the VNC Server:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
service vncserver restart<\/code><\/pre>\n
Now kill the VNC Server:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
vncserver -kill :1<\/code><\/pre>\n
Edit the xstartup file in .vnc directory:
\n<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
nano .vnc\/xstartup\n<\/code><\/pre>\n
Comment the last line and run the Gnome:<\/strong><\/p>\n

#twm & \nexec gnome-session &<\/code><\/pre>\n
Restart the service:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
service vncserver restart<\/code><\/pre>\n
Now, download VNCViewer onto our desktop computer from which we want to access the shared desktop.
\nConnect using ServerIP\/Name:1 (:1 is for the VNC server window)<\/p>\n
http:\/\/www.realvnc.com\/download\/viewer\/
\n<\/a><\/p>\n
Enter the password that we created using the vncpasswd command:<\/p>\n
Ability to connect for multiple users:
\n<\/strong>
\nCreate a local user, using the following command:<\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
adduser ali<\/code><\/pre>\n
Create a password for newly created user:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
passwd ali<\/code><\/pre>\n
Switch to the newly created user and run vncpasswd command for it:<\/p>\n
su ali<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
vncpasswd<\/code><\/pre>\n
Edit the \/etc\/sysconfig\/vncservers file:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
nano \/etc\/sysconfig\/vncservers<\/code><\/pre>\n
Add these lines for new user:<\/strong><\/p>\n

VNCSERVERS=\"1:arbab 2:ali\"\nVNCSERVERARGS[1]=\"-geometry 1024x600\"\nVNCSERVERARGS[2]=\"-geometry 1024x600\"<\/code><\/pre>\n
Restart the VNC service:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
service vncserver restart<\/code><\/pre>\n
Kill the vncserver session for new user and edit the xstartup file:<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
su ali\nvncserver -kill :2\ncd ~\nnano .vnc\/xstartup\n<\/code><\/pre>\n
Modify the file so it looks like this:
\n<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n

Restart the VNC service:
\n<\/strong><\/p>\n
Code:\u00a0[Select]<\/a><\/div>\n
service vncserver restart<\/code><\/pre>\n
