Hi, I’m playing around with sockets in ruby and took a look at the docs([http://www.ruby-doc.org/stdlib/libdoc/socket/rdoc/index.html](http://www.ruby-doc.org/stdlib/libdoc/socket/rdoc/index.html)). There are some examples like this here([http://www.ruby-doc.org/stdlib/libdoc/socket/rdoc/classes/Socket.html#M004166](http://www.ruby-doc.org/stdlib/libdoc/socket/rdoc/classes/Socket.html#M004166)): ``` require 'socket' include Socket::Constants socket = Socket.new( AF_INET, SOCK_STREAM, 0 ) sockaddr = Socket.pack_sockaddr_in( 2200, 'localhost' ) socket.bind( sockaddr ) socket.listen( 5 ) client, client_sockaddr = socket.accept puts "The client said, '#{socket.readline.chomp}'" client.puts "Hello from script one!" socket.close ``` But that example is wrong! It has to be client.readline.chomp and not socket.readline.chomp. Take this example by me: #!/usr/bin/env ruby $Verbose=true require ‘socket’ mysocket = Socket.new(Socket::AF\_INET, Socket::SOCK\_STREAM, 0) socketaddress = Socket.pack\_sockaddr\_in( 2201, ‘localhost’ ) mysocket.bind(socketaddress) mysocket.listen( 5 ) client, client\_sockaddr = mysocket.accept puts client.readline.chomp #reading from the client fd mysocket.close execute it and connect with netcat: “nc localhost 2201” , now type something in netcat and you will see everything is fine but now let’s change it to the doc way: #!/usr/bin/env ruby $Verbose=true require ‘socket’ mysocket = Socket.new(Socket::AF\_INET, Socket::SOCK\_STREAM, 0) socketaddress = Socket.pack\_sockaddr\_in( 2201, ‘localhost’ ) mysocket.bind(socketaddress) mysocket.listen( 5 ) client, client\_sockaddr = mysocket.accept puts mysocket.readline.chomp #reading from the socket fd mysocket.close If you connect now to it with nc the ruby-script will crash: ./sockettest.rb:13:in `readline’: Transport endpoint is not connected (Errno::ENOTCONN) from ./sockettest.rb:13 Can someone confirm it and who’s gonna fix this doc-error? ---
