create a tcp client in ruby

To create a TCP client in Ruby, you can use the socket library which is a part of the Ruby standard library.

Here is an example TCP client that connects to a remote server and sends a message:

main.rb
require 'socket'

# IP address and port of server to connect to
server_ip = '192.168.0.10'
server_port = 1234

client_socket = TCPSocket.new(server_ip, server_port)

# Send a message to the server
client_socket.puts('Hello, server!')

# Read the response from the server
response = client_socket.recv(1024)
puts "Received response: #{response}"

# Close the socket
client_socket.close
385 chars
18 lines

In the example above, we create a new TCPSocket object and pass in the IP address and port of the server we want to connect to. We then use the puts method to send a message to the server and recv method to read the response from the server. Finally, we close the socket using the close method.

You can use this code as a starting point to build more complex TCP client applications in Ruby.
