I used to use MTPutty for managing my SSH Logins on Linux Servers. That tool allows me to send predefined Scripts such as:
sudo apt-get update && sudo apt-get dist-upgrade
to those Machines wich needed an Update.
###wait 15 lets the Script wait for 15 Milisecondes for the Password Promt to show up, after that it sends the "P@ssw0rD" to the server for sudo authentication.
That was very practical for me to update 20 oder 30 Servers at once.
This feature would be very very very nice to have in mRemoteNG.
