Simple Sockets

This is a Simple Sever and Client I created while following this tutorial C/C++ Sockets Tutorial. The goals of this project were to get back into C++ and learn about sockets and designing servers.

Compiling the Code

Build the project
cmake --build cmake-build-debug --target simple-socket-server
cmake --build cmake-build-debug --target simple-socket-client

move into the build directory
cd cmake-build-debug

Set the executable bit on the executables
chmod +x simple-socket-server
chmod +x simple-socket-client

move the executables to a better location
mv simple-socket-* [some location]

Running the pre-complied versions

Compiled on Debian kernel version 5.16.11-76051611-generic arch x86_64

Note: if you are compiling the code you can skip the first 3 steps as they are performed above

Change directory to built
cd built

Set the executable bit to the executables
chmod +x simple-socket-server
chmod +x simple-socket-client

move the executables to a better location
mv simple-socket-* [some location]

Move to the directory you placed the executables in \

Run some commands
./simple-socket-server 5546 Note: if you placed the executable in PATH you do not need the proceeding ./

In a new terminal
./simple-socket-client 127.0.0.1 5546 Note: if you placed the executable in PATH you do not need the proceeding ./

Further Reading

I have started reading the following after completing this tutorial

• TCP/IP Sockets in C, 2nd Edition by Michael J. Donahoo, Kenneth L. Calvert

Future Plans for the Project

• Fork off new Processes to handle multiple connections
• Implement a fix for the zombie problem the above step will assuredly create
• Complete this project by having the server take a screenshot of the current desktop environment and pass it to the client.
