Chris Overly's first week assignment

I accidentally placed all the scripts in the lab folder instead of the athome folder. I'll try to correct my bad behavior for next week.

I have included 3 pairs of scripts:
pair 1: basic echo server & client.
pair 2: my sum server/client
pair 3: my sum server/client set up for my VM. I'll get the script running on my VM now.
