Net::EmptyPort

This module can find, check and wait an empty TCP/UDP port.

Add this line to your application's Gemfile:

gem 'net-empty_port'

And then execute:

$ bundle

Or install it yourself as:

$ gem install net-empty_port

port = Net::EmptyPort.empty_port
TCPServer.new('127.0.0.1', port)

Net::EmptyPort.used?(port)

Net::EmptyPort.wait(port, 3)

This module is originally in a perl module Test::TCP written by tokuhirom. Thanks a lot.

This module is similar, but only for starting a server process.
