How to run shell/perl scripts on remote machines from web in


I am currently making a web interface which will have Click Buttons
that should invoke a shell script on a remote machine

I have to execute these shell scripts on many such machines and monitor

them, and it is very time-consuming. So i look forward to make a web
interface that will control these scripts.

According to you:

  1. Which is the best language to prepare web interface ?

  2. How to make connectivity and authentication (user/passwd) from web
    interface to remote Unix/linux machine ?

  3. How to start shell/perl script and check if it is completed or not ?

  4. Is it possible to invoke Remote Desktop through VNC service by the
    click of a button?

I would appreciate if you can provide any answers to these questions.
Thanks in advance.
