in thread Net::SSH::Perl and su

something I really don't get is:
"Why ssh to a remote machine (as a regular user), THEN su to root?"
Assuming the user is "hossman" on both machines, you're doing this... 
    hossman@client =ssh=> hossman@server =su=> root@server

Why not do this instead... 

    hossman@client =ssh=> root@server

(sudo is nice because it eliminates the need for hossman to know the root password on server, but the same thing could be accomplished using ssh keys.)

    "Why ssh to a remote machine (as a regular user), THEN su to root?"

    Because many ssh servers block direct root logins, so you need at least two passwords to get a root shell. (in general)

    Root user not allowed to log in directly. You only log in as regular user then su to root.
