Backconnectd is a tcp daemon capable of accepting and holding multiple connections, eg. reverse shells, for future interractions.
To install the binary, you have to build it from source:
make
make install
Also, a systemd service file is included. It can be installed with make install-service
Run backconnectd with ./backconnectd -config config.yml.
The server will listen on two addresses specified in config file, one is for backconnections, other is for admin connections.
Intended admin client is nc. Admins can choose session to interract with, after that the server will act as a proxy between admin and backconnection.
Exiting does not stop existing sessions. Data sent through backconnection before admin interracts with it is buffered and sent to admin as soon as he connects to the session.
Backconnectd may be useful for CTF players or pentesters who feel tired of running nc -l every time they need a reverse shell to connect to them, or need many reverse shells at once.
