VNC is useful to remotely to control one computer .
1. Install
yum install vnc vnc-server
2. Setting the vnc account
edit the file : "vim /etc/sysconfig/vncservers"
VNCSERVERS="1:root 2：roc"
3. Set the password for the different account
As root user , run "vncpasswd" command to set the password;
Then run the command again as roc user.
4. Start the servers
service vncserver start
5. Test it by vncviewer
vncviewer localhost:1 or vncviewer localhost:2
It should be work.
6. Open the firewall to be access by other users
6.1 vim /etc/sysconfig/iptables
Add below two lines in that file
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 5902 -j ACCEPT
6.2 Apply the new rules for the firewall
service iptables restart
7. Then other users can access it in remote.
vncviewer ip:1
if you cant access it , you can stop the iptable to try it again. ( service iptable stop)
