sudo: sorry, you must have a tty to run sudo

Ran into this the other day at work on RHEL5. Unfortunately, net searches come up with a not-so-great answer - "just comment out Defaults requiretty." Don't you think it's there for a reason?

The reason is that without having TTY control characters interpreted, unless you are using the "NOPASSWD" option, sudo cannot mask out your password and it will be printed to your screen for all to see!

The simplest (and most proper IMHO) work-around is to simply use "ssh -t" instead of "ssh" in your command line that is calling sudo on the remote machine.
