Ruby脚本在Linux中管理网络端口

发布时间:2024-09-15 10:44:39 来源:亿速云 阅读:84 作者:小樊 栏目:建站服务器

在Linux中,你可以使用Ruby脚本来管理网络端口

  1. 安装Ruby(如果尚未安装):
sudo apt-get update
sudo apt-get install ruby
  1. 创建一个名为port_manager.rb的Ruby脚本文件:
touch port_manager.rb
  1. 编辑port_manager.rb文件并添加以下内容:
require 'socket'

def open_port?(ip, port)
  begin
    socket = TCPSocket.new(ip, port)
    socket.close
    true
  rescue Errno::ECONNREFUSED, Errno::EHOSTUNREACH
    false
  end
end

def manage_port(action, ip, port)
  case action
  when "check"
    if open_port?(ip, port)
      puts "Port #{port} is open on #{ip}"
    else
      puts "Port #{port} is closed on #{ip}"
    end
  when "open"
    # To open a port, you need to run a server on that port.
    # Here's an example of how to do it with a simple HTTP server:
    server = TCPServer.new(ip, port)
    puts "Port #{port} is now open on #{ip}"
    Thread.new do
      loop do
        client = server.accept
        client.puts "Hello from port #{port}!"
        client.close
      end
    end
  when "close"
    # Closing a port requires stopping the service running on that port.
    # This is beyond the scope of a simple script and depends on the service itself.
    puts "To close a port, you need to stop the service running on it."
  else
    puts "Invalid action. Use 'check', 'open', or 'close'."
  end
end

if ARGV.length == 3
  action, ip, port = ARGV
  manage_port(action, ip, port.to_i)
else
  puts "Usage: ruby port_manager.rb<action> <ip> <port>"
  puts "Actions: check, open, close"
end
  1. 运行脚本以检查、打开或关闭端口。例如,要检查IP地址为192.168.1.100的设备上的端口8080是否开放,请运行:
ruby port_manager.rb check 192.168.1.100 8080

请注意,此脚本仅用于演示目的。在实际应用中,你可能需要根据你的需求对其进行修改和优化。
