You would use the ‘socket’ library. See  
[http://www.ruby-doc.org/docs/ProgrammingRuby/html/lib\_network.html](http://www.ruby-doc.org/docs/ProgrammingRuby/html/lib_network.html)  
[http://www.ruby-doc.org/stdlib/libdoc/socket/rdoc/index.html](http://www.ruby-doc.org/stdlib/libdoc/socket/rdoc/index.html)

Google for “ruby socket API” turns up tutorials such as
