initialize connection with metasploit rpc in ruby

Here is how you can initialize connection with Metasploit RPC in Ruby:

main.rb
require 'msfrpc-client'

# Initialize a new client
client = Msf::RPC::Client.new(
  host: '127.0.0.1',   # The IP address of the Metasploit RPC server
  port: 55553,         # The port used by the Metasploit RPC server
  username: 'user',    # The username to use for authentication
  password: 'password' # The password to use for authentication
)

# Test the connection by executing a simple command
result = client.call('core.version')
puts "Metasploit Core version: #{result}"

In this example, we use the msfrpc-client gem which provides a Ruby client for the Metasploit RPC interface. We start by initializing a new Msf::RPC::Client object with the IP address, port, username, and password of the Metasploit RPC server. We then test the connection by calling the core.version command and outputting the result.

Note that you'll need to have the Metasploit Framework installed and configured to use the RPC server in order to use this code.
