ric

"Weddings are basically funerals with cake."

by Rick, from "Rick and Morty"

ric is an implementation of:

• Sanguino, J., "A Quick Guide to Networking Software", 5th Edition, Feb 2020

It also aggregates all tasks into a single program called ric.

The name is a pun to the Course from which the guide is (RCI), as well as the spirit of the project itself, which tries to expose more of the cool stuff, in a bold and sarcastic manner of the one Rick.

Correspondence

We built libric, based on the exercises. The header can be found in the include folder, as ric.h.

The source file correspondence is as follows:

• src/ric/hname.c -- task 1: gethostname
• src/ric/nslook.c -- task 2: getaddrinfo
• src/ric/udp_client.c -- task 3, 4, 5: udp_client
• src/ric/tcp_client.c -- task 6, 7, 8: tcp_client
• src/ric/udp_server.c -- task 9: udp_server
• src/ric/tcp_server.c -- task 10, 11, 12: tcp_server

It was properly adapted. The signal catching, is found in the base src/ric.c.

ric's flags

Box for statuts of implementation.

• n -> Task n(hostname) -> Task 1
• w -> Task w(who is it, weak nslookup) -> Task 2
• u -> Task udp_client -> Task 3, 4, 5
• t -> Task tcp_client -> Task 6, 7, 8
• l -> multiplexes u and t to servers
  • u -> Task udp_server -> Task 9
  • t -> Task tcp_server -> Task 10, 11, 12

ROADMAP

• Finish implementing the guide.
• Find proper documentation methodology.
• Develop such documentation.
• Extend to other features.
