linux_socket Repo

Brief:

This is a simple UNIX client and server socket implementation. That currently handles two commands.

1. VERSION --> This responds with latest git hash

2. quit         --> will close the socket server

3. Server should respond with rejected for anything else

Notes:

This is a very rough version of client and server socket implementation. There is not a lot of error checks

The error check that I have right now is only on the amount of arguments that we are passing.

Future implementation:

1. Man page implementation for this

2. Error checks around the arguments passed

3. Attempt to clean the code

Usage:

The docker file should be provided to you in an email or reach out to shravansingh64@gmail.com

1. Create a Directory for you docker on your system
2. Build docker with command docker build -t testdocker -f ./Dockerfile .
3. Run docker docker run -t testdocker
4. Inside your container run make all
5. Start the server ./socket_server /tmp/socket &
6. run the client with socket path and command for example ./socket_client /tmp/socket VERSION
7. To stop the server ./socket_client /tmp/socket quit
8. The server should respond with rejected for everything else

Cross-Compilation:

1. If the container and docker has been closed then please start the docker again using`docker run -t testdocker`

2. Run`pwd` inside the container to check where we are by default we should be at `/opt/DockerEnv/linux_socket`

3. Run the following commands to navigate to`aarch64_toolchain` and extract the toolchain

cd ..
cd aarch64_toolchain/

4. Run`pwd` to make sure you are in `/opt/DockerEnv/aarch64_toolchain`

5. Run`tar -xvf aarch64--glibc--stable-2024.05-1.tar.xZ`

6. Now with tool chain extracted, lets go back to linux_socket directory by going back a directory`cd ..` and then entering a directory  `cd linux_socket/`

7. Check to see is`version.h` file exits by perfoming `ls` and output should be as below `get_latestHash.sh  LICENSE  Makefile  README.md  socket_clientsocket_client.cpp  socket_server  socket_server.cpp  version.h`

8. if version.h does not exist then from directory`linux_socket` run `./get_latestHash.sh`

9. Now to cross-compile, we will provide the aarch64 linux g++ and sysroot as below from`linux_socket` directory as shown below
