Question

I am using ssh for connecting one of the systems.

I have a perl script in that system which I have to run from my machine. But the commands in remote system runs only when it is in Super user mode (I give su – to become the super user, if I am working directly on the remote system)

But if I have to run the perl script from my system ( I am using OpenSSH for this purpose), in super user mode, how should I do it?

By the way, I have placed the command $sh->system("su -") . But it asks for the password but does not proceed further. I have waited for 5 mins atleast, even then I didnt get any response after I entered the password.

Can anyone say how to deal with this situation?

If you don’t want ssh to ask for the password, you can add your client user key in the server .ssh/authorized_keys file of the target user. Using this, ssh won’t ask for a password anymore.
