[Deb-SEC]oddball ssh remote passwd question
Hello all, This is far from as serious an issue as some of the items on the list right now, but I thought I'd see if anyone has some input. I'm running some synchronized machines, and I only want users to change passwords on the master. So, I thought of writing a script to replace password that just uses ssh to remotely call password on the master machine and let them change it there... Well, here's the rub. if you do: ssh [EMAIL PROTECTED] password ssh will have you authenticate to host, and then bring up the password change prompt (current) UNIX password: on the remote machine. BUT when you start typing, the characters show up on screen- not hashed or unprinted. What is it that is striping this functionality from passwd? Failing finding a way to get ssh to not express these characters, I could swear there is a simple way of turning off echoing input to the screen, but for the life of me I can't remember the command or variable in bash. Anyone feeling charitable and want to help out since my memory is failing? Thanks, David. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Tim, Yep that does it :) Thanks mucho! I knew it was something VERY simple but my brain is just stir-fried today and I couldn't think of it. Thanks again. David.
