ft_irc

A small, standards-oriented IRC server written in C++98. Created for learning and as part of the 42 Vienna curriculum.

Features

• User registration (PASS / NICK / USER)
• Basic channel support: JOIN, PART, TOPIC, MODE
• Private and channel messaging: PRIVMSG
• Invite and kick: INVITE, KICK
• Ping/pong handling
• Graceful QUIT handling

Requirements

• GNU Make
• A C++98-compatible compiler (tested with g++ / clang++)

Build

Build the server using the included Makefile:

make

This produces the ircserv binary in the repository root.

Clean build artifacts with:

make clean
make fclean  # removes the binary too

Run

Start the server with a port and password. Example:

# run on port 6667 (default IRC port)
./ircserv 6667 my_server_password

Connect with a client

Connect with a full IRC client (e.g. irssi) or use netcat for quick testing:

# using netcat
nc -C localhost 6667

# using irssi
irssi -c localhost -p 6667 -w my_server_password

Example registration sequence (manual via netcat):

PASS my_server_password
NICK mynick
USER myusername 0 * myrealname
