If you'd like a local copy of the server program to analyze, use these commands:
nc attack.samsclass.info 13010
Exploit this process and get a shell on the server. Then put your name in this file:
curl https://samsclass.info/127/proj/p13x.c > p13x.c curl https://samsclass.info/127/proj/p13x > p13x
Create this file:

- There is no firewall, so a simple port binding attack will work.
