The client is pretty flexible on what we do here, and you've given me some good ideas on how to set it up.

Do-Over a mangled sudo password?
Simple question, I expect, but haven't been able to locate the answer. I'm working in an environment where I have to sudo a number of commands when logged into a remote machine via ssh. The password is a doozy, with upper-, lower- punctuation, numbers and a spin of the secret decoder ring. Inevitably, I get halfway through the password entry and miss a character, slip off the shift key, forget where I was or something. Is there a way to clear the characters I've entered and start again, without hitting enter, waiting for the timeout, hoping I haven't exceed the limit and trying again? I suspect this is one of those Everyone knows it's Ctrl-K but I must have dozed off in class.

Um, maybe I'm missing something obvious here, but have you tried the [BACKSPACE] key? My preferred technique is to position my index and middle fingers over the key and alternate them back and forth very quickly a couple dozen times. :-) -- Ben It's the most used key on my keyboard Scott ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss

Others have already provided working answers, so I won't bother reiterating :) I'm working in an environment where I have to sudo a number of commands when logged into a remote machine via ssh. Have you thought of a different approach? I don't know what your limitations are wrt sudo use (i.e., are you using it for it's logging/safety, or has it been imposed upon you by your sysadmin?) Assuming you can do anything you want, you just need to provide a password, one obvious thing is to 'sudo su', then run the commands you need. Another obvious thing, provided you have the capability, is to ssh directly to the remote machine as root, completely by-passing sudo. A not-so-obvious thing, but one which might invoke a 'Duh!' would be to wrap up your commands into a shell script, then run the single shell script under sudo.

Set up different keys for different commands, then when ssh'ing, you can specify which key to use, which in turn dictates which command to run on the remote side. Of course, all these things require that you have a little flexibility with your sudo/ssh environment. -- Seeya, Paul ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss
