Greetings Brothers,

I hope you can forgive a question that isn't necessarily Perl related. I am forced to write a script that must log into a bastion server to log into *another* server to do stuff. I need to pass the root password to this script on the other machine.

On the local machine, I enter the password with no echo, and hold it in a variable in memory. I then ssh into the bastion host and execute another script there--and that's where I need to feed it the root password to the third box.

Simple, right? ;-)

I've contemplated sending it as an argument, but then it will show up in the process list. I've contemplated sending it over another socket, but that seems very complicated.

Any ideas?
