15-441: Project 1/Checkpoint 1

Checkpoint 1 is worth potentially 10 total points out of 100 towards Project 1. The work started here, when completed, will be worth 35 total points out of 100. To receive the points and begin working on Project 1 you must:

1. Make a git repository for your project as described in the handout.
2. Create a select()-based echo server with support for multiple concurrent clients.
• Test using our provided cp1_checker.py test script (read that script and understand it too, Python recitation upcoming...)
• Submission is in the form of a git tag (see handout) which must exist in your repository by next Friday (cut off is midnight).

To aid you in programming an echo server, and testing it, we have prepared this starter package for you. This code needs to be modified to use select() as well as adding support for multiple clients at once.

Files we expect to see:

• Makefile - make sure nothing is hard coded specific to your user; should build a 'lisod' file which runs the echo server
• All of your source code - all .c and .h files
• readme.txt - file containing a brief description of your current implementation of lisod
• tests.txt - file containing a brief description of your testing methods for lisod
• replay.test - a file containing bytes that can be sent to your lisod as a test case
• replay.out - a file containing expected bytes that should be sent as a response from your lisod when provided replay.test
• vulnerabilities.txt - identify at least one vulnerability in your current implementation
