This project is a very simple client-server TCP chat program. It results from a personal effort to teach myself networking, so it's a toy/learning project rather than anything serious.
It can be run on Both Linux and Windows, although the Windows compatibility layer is less well-tested.
It has been designed to depend on as few other packages as possible. It depends on:
make- a C compiler toolchain such as Clang, GCC, or MinGW
- A few common utilities like
rm
This can be set up using Guix as:
guix shell gcc-toolchain make
To build, you can run:
make
This gives you the binary chattr.
After building, you can simply type ./chattr to run. It will then ask whether you want to run as a client or a server.
$ ./chattr
Client or server? [cs]: s
Enter a port number: 2000
Making socket on port 2000
Setting socket 3 as non-blocking
Socket bound and listening...
Then you can get a client to connect from another computer after first building on that machine.
$ ./chattr
Client or server? [cs]: c
Enter an IP address: 192.168.1.43
Enter a port: 2000
Connecting to 127.0.0.1 on port 2000...
Setting socket 3 as non-blocking
Successfully connected!
Enter a username: Abigail
Welcome!
/identify Abigail
> hi
Sending 'hi'
*hi
>
You can connect with as many clients as you like:
$ ./chattr
Client or server? [cs]: c
Enter an IP address: 192.168.1.43
Enter a port: 2000
Connecting to 127.0.0.1 on port 2000...
Setting socket 3 as non-blocking
Successfully connected!
Enter a username: Babylas
Welcome!
/identify Babylas
> hello Abigail
Sending 'hello Abigail'
*hello Abigail
>
Then Abigail will see:
/identify Babylas
*hello Abigail
>
And they can carry out a conversation.
To reiterate, this isn't a big, polished project, but it is just a way to exercise my skills and teach myself how to network computers.
