Sometimes when I’m really busy, I forget to look at the hostname and end up executing a command on the wrong computer. To solve this, I simply set up a couple of different profiles (one with a black background, one with white, etc.) and ssh into the box using a launcher which executes the following command:
gnome-terminal –window-with-profile=customprofile2 -e ‘ssh yourdomain.com’
This example is with Gnome terminal but if I remember correctly, you can do this with putty if you’re on Windows.
