Top Forums Shell Programming and Scripting Bash script connect to remote servers and become root Post 302811537 by DGPickett on Thursday 23rd of May 2013 04:03:11 PM

Yes, ssh is more secure with PPKey not password, as well as allowing simpler scripting. Once in as not root user with a controlling terminal (-tt), accessing root with any interactive commands is fine, but once again, you may need expect or something like it to send the root password, or sudo so you do not need to use and expose that password.

You could write your own set-uid root compiled program to let just your trusted id or group run just scripts in a special directory.
