Simplistic Command Server

A simple TCP Server that is able to execute pseudo-commands. By default Listens into localhost and port 7070 (no terminal parameter are provided yet). I made this kind of server in order to learn better C++.

Build, develop and run unit test

• make build: builds the application.
• make run : Builds and runs a production-ready binary executable.
• make debug: Debugs the application (needs gdb)
• make test_command_parser_build: runs the unit test for command parser.
• make test_command_parser_run: is running the unit test compiled above.

On make commands you can provide a parameter DEBUG with values either 1 or 0, 1 indicated that the projhect will be build with the appropriate flags in order to be able to debug it with g++.

For unit tests I use the cxxtestgen and in Ubuntu GNU/Liux is available via the command:

sudo apt install cxxtestgen

In order to send commands you can utilize the UNIX nc command:

netcat ^host^ ^port^ <<<$'^command^\n^command^\n...exit\n'

A toy example of using the netcat is:

 nc -4 localhost 7070 <<<$'hello\nhello\nexit\n'

Command Line arguments and run

The server uses the following mandatory command-line arguments:

• -h That the host is specified.
• -p That the post is specified.

Any executable and usefull binary is build upon build/release the unit tests are built in build/testing in order to run it from the cli on a console run:

./build/release/server -h ^host^ -p ^port^

Available commands:

The following commands are available:

• hello That returns the message hello
• exit That indicates the end of the command sequence.

Each command is being seperated with \n.
