title: How to telnet an address?
body: <p>I'm trying to understand the socket class and i'm using the following example to implement a server sample</p>
  
  <pre><code>local server = assert(socket.bind("*", 0))
  
  -- find out which port the OS chose for us
  local ip, port = server:getsockname()
  
  -- print a message informing what's up
  print("Please telnet to localhost on IP [" ..ip.. "] and port [" .. port .. "]")
  print("After connecting, you have 10s to enter a line to be echoed")
  
  -- loop forever waiting for clients
  while true do
  -- wait for a connection from any client
  local client = server:accept()
  
  -- make sure we don't block waiting for this client's line
  client:settimeout(10)
  
  -- receive the line
  local line, err = client:receive()
  
  -- if there was no error, send it back to the client
  if not err then
      client:send(line .. "\n")
  end
  
  -- done with client, close the object
  client:close()
  end
  </code></pre>
  
  <p>But now the question is, how can I telnet for example the address localhost:8080 via lua?</p>
  
  <p>EDIT:
  I forgot to tell something, I don´t even can telnet on cmd. When I type the command:</p>
  
  <p>telnet ip port</p>
  
  <p>it always says "connection lost" after I send a message. What am I doing wrong?</p>
