Client-Server Socket in C

Files

server.c - C source code for the server

client.c - C source code for the client

tands.c - C source code for the Sleep() and Trans() functions

tands.h - header file for the Sleep() and Trans() functions

server.man - manual page source code for the server

client.man - manual page source code for the client

Assumptions

The server is not multi-threaded, it serves all clients in a first come first served manner. Clients will be waiting in a queue while the previous client is being served.

Approach

The server is implemented as a loop that checks for timeout condition (30 seconds) in each iteration.

The first message from each client is reserved for machine name and pid information.

The client first send its machine name and pid to the server, and loops through every command from stdin and then send / execute them. If a command is sent, the client waits for server reply.

Instruction

Compile and generate files

Compile (or Re-compile) everything (clean build, including manual pages)

make

Compile server and client only, non-optimized

make build_all

Compile server and client only, optimized

make build_all_optimized

Generate manual pages (in pdf)

make man

Clean

# clean

Make zip file

make zip

Run

Run server

./server port

Run client

./client port ip-address

The client reads in from stdin by default, so if the input is from file, use:

./client port ip-address < inputfile
