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 "
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.
