    Amarendu,

    What is the question?

    Do you need to encrypt the password?

    Do you need to save it in a safe place, etc??

    Thank you

      I have a user named "hduser" and the password of the user is say "xyz123". Now I need a automated script for it so that I can get logged in as hduser without prompting for it's password. For example I have written a perl script as follows: #!/usr/bin/perl system ("su hduser && <xyz123>"); I need to set the user password for hduser. Please help urgently. Thanks a lot in advance.

        If you want your script to run with the privileges of user "hduser" without having to enter that user's password you should probably investigate Secure Shell.

        Cheers,

        JohnGG

      I don't exactly need that you have specified. I don't want to prompt the user for a password. In my local system I run say two commands like "su hduser" which prompts me for a password and entering the password I get logged in as hduser. I just need to automate this thing using a script in my local system only so that I don't have to do this from the command line. Thanks in advance any help would be of great help.
        You can always configure /etc/sudoers to not require passwords -- either for all commands or for a list of specified commands.

    Use SSH with digital certificates for password-free login. Be sure that each computer has its own unique certificate. It's also a good idea to password-protect (encrypt...) each certificate and to use an ssh-agent to store those keys. Tighten down the scenario as tightly as you can ... if you know IP-addresses, lock the connection to them.
