You don't have "something" I need on the server how can I get it installed?

Either you can compile the application into your home directory or your can email help@poly.edu and we'll see if we can install it.

I'm getting a security breach error when I try to SSH in. What do I do?

You are either getting this error because the host key was changed on the server and it differs from the key that you receive when you originally connected to the server. You should have been notified if the host key was changed on the server via email. If you were not notified please contact help@poly.edu about the problem.
Using puTTy: You will get a pop up window stating that the host keys don't match. All you need to do is simply click yes to update your key to the new one.
Using Unix/Linux You will get a message stating that the host keys don't match. However, you will not be able to connect until you remove the old key. To remove your old keys simply type the command: echo "" > ~/.ssh/known_hosts
