Shell Script - rdesktop.sh

This script hasn't been perfected yet but I almost lost it once. So, here it is so I don't almost loose it again. I know it would be semi-easy to re-create but hey, why re-create when you can just go back and find it again!

I use this so I can automatically pull up computers at work after hours and do maintenance. You can either leave the password field blank or put it in the script to auto-login for you. IF you put the password into the script, be careful. Someone may be able to read your script and get your password!

I do need to update this script. For some reason if it doesn't find port 3389 open on a remote host in the list it will spit out the results from 'nmap --help'. This is ok as it will just move onto the next IP but if you know how to fix it I would love to know how. Keep checking back for updates.
