To use PuTTY to connect to a Linux system at the TCC:
Open the PuTTY application.
Double click on one of the names in the "Saved Sessions" box. The
author suggests "rainbow", but it doesn't matter for
basic use. The first entry, "Default Settings", won't work.
The first time you do this, something like this will come up:
Click on "Yes".
After that, and every other time you connect, you will get this
screen:
Enter your username and password here.
If all goes well, you should get to something like this:
and you can do what you normally would with a terminal connection to
the TCC.
