Why to use remote desktop sessions like VNC over traditional Putty sessions !

Remote desktop sessions like VNC are very favourable for the users where if they need their remote screen to be in active state and if they are running some configuration and doesn’t want their action/CLI’s to hung if the local screen goes in sleep mode or looses their internet connection somehow. VNC is real savior in those cases where you don’t loose your hours and hours of spent work.

• Once Login is sucessfull to the server you would be able to see bash prompt, type “tcsh” to see the server name and go to enable prompt.
  bash-3.2$tcsh
  server-1:1>
  
• Once above prompt comes type “vncserver” and hit enter. This will create a new VNC desktop sessions and will list its name as below :
