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. Register an account with our installation of Indefero. This will serve as your project site, a place for future collaboration on projects 2 and 3, and also a source repository for all of your projects.
• Register with your Andrew ID here: http://sourcery.cmcl.cs.cmu.edu/indefero/login/
2. Create a public/private key pair and upload your public key as ASCII text into Indefero via account management. Paste the public key contents into the box labeled "Add a public SSH key:" located at this URL http://sourcery.cmcl.cs.cmu.edu/indefero/preferences/
• You can create a keypair by following these instructions: https://help.ubuntu.com/community/SSH/OpenSSH/Keys
This is operating system-dependent; you must look up documentation for your system (or come to office hours)
3. Create a private project using git as the source control system.
• Name your project using this scheme (to avoid name collisions): <andrewid>-15-441-project1
• Project creation link: http://sourcery.cmcl.cs.cmu.edu/indefero/admin/projects/create/
4. 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 checkpoint-1 xxXXxxXXxx' which must exist in your repository by next Friday (cut off is midnight).
• Final step is to upload the tag via 'git push --tags'

To aid you in programming an echo server, and testing it, we have prepared this starter package for you. It contains a cp1.py test script, as well as the echo server and client code from Recitation 1. This code needs to be modified to use select() as well as adding support for multiple clients at once.

Files we expect to see in your 'git tag checkpoint-1 xxXXxxXXxx' (fill in the x's with the commit you want to submit, don't forget to push!):

• 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
