I am connected to a production environment with my user-name. From my user i go to a super user account 'superuser' using command "sudo su superuser" and it logs me in as super user. It seems some ssh key authentication is used here and that's why i am able to login without any password.
Now I want to use perl to automatically log me in to this user so that i can fire commmands. When I am logged in as non-superuser, i am not able to issue sudo su superuser command and it returns error.
Is there any way possible that I ssh to my own user and then log in to other user using any SSH Module. I tried net::ssh::expect but there is no success.
