To Login From Windows, using PuTTY

To log in to ACRES from a Windows machine,

Host Name = "acres.clarkson.edu"

Port = 22

Connection type = SSH

As shown below:

Step 3) Click "Open".

Step 5) You now have access to a linux shell (command line) on ACRES. You should see a welcome message, and a report of your hard drive usage quota.
