How to use the command 'rc' (with examples)

The rc command is a modern simplistic port listener and reverse shell, similar to nc (netcat). It provides a user-friendly way to listen on a specific port or establish a reverse shell connection with a host.

Use case 1: Start listening on a specific port

Code:

rc -lp <port>

Motivation: This use case can be helpful when you want to monitor incoming network connections on a specific port. It allows you to establish a listening socket and capture data sent to that port.

Explanation:

• -lp: The -l option indicates that rc should start listening on the specified port, and the -p option specifies the port number to listen on.
• <port>: Replace this with the desired port number to start listening on.

Example output:

Listening on port 5000...

Use case 2: Start a reverse shell

Code:

rc <host> <port> -r <shell>

Motivation: This use case is useful when you want to establish a reverse shell connection to a remote host, allowing you to execute commands on that host from your local machine.

Explanation:

• <host>: Replace this with the IP address or hostname of the remote host to connect to.
• <port>: Replace this with the port number on the remote host to connect to.
• -r: The -r option indicates that rc should establish a reverse shell connection.
• <shell>: Replace this with the shell type or command you want to execute on the remote host.

Example output:

Reverse shell connection established with host: 192.168.1.100, port: 8080

Conclusion:

The rc command is a versatile tool for monitoring network connections and establishing reverse shell connections. It provides a simplified way of interacting with ports and remote hosts, making it a handy utility for various use cases. Whether you want to listen on a specific port or gain remote access to a host, rc simplifies the process while providing similar functionality to nc.
