* VNC Server allows sysadmin to administer the server in GUI environment provided the server is able to boot up in run level 5. We are setting up 2 users for vnc access in this instance.
* If not already done, install vnc server.
yum install vnc-server
* In /etc/sysconfig/vncservers
VNCSERVERS="1:user1 2:user2" VNCSERVERARGS[2]="-geometry 1280x1024" VNCSERVERARGS[3]="-geometry 1280x1024"
* Manually switch between users and run vncpasswd. Assuming you are root.
su - user1 vncpasswd // repeat for x number of users
* Open up the vnc ports in the firewall. The vnc ports start from 5901. So if I have 5 users, the port range is from 5901 to 5905
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 5902 -j ACCEPT
* restart firewall and vncserver
service iptables restart service vncserver restart
* (optional) To allow users to have access to the Gnome interface. Go to the user’s home directory
vim ~/.vnc/xstartup
* Uncomment these 2 lines
unset SESSION_MANAGER exec /etc/X11/xinit/xinitrc
Restart the vncserver again.
* All done. Test it out!
