How to submit your work to your AFS hand-in directory
Option 1: Use a File Transfer Client, such as SSH Secure File Transfer. (Download the software from https://www.cmu.edu/myandrew/ )
Connect to unix.andrew.cmu.edu and enter your userid and password.
You will now see your personal account on the remote AFS directory as shown below:
For the remote name, type in /afs/andrew.cmu.edu/course/24/682/handin-1/ followed by your Andrew user ID. Then, drag and drop necessary files from the left pane (local machine) to the right pane (remote AFS directory)
