    <p>My problem is that I'm creating a FTP client, and so far its working flawlessly besides one minor detail, that keeps bugging me. I need to know how many lines the FTP welcome message spans over... And this cannot be acceptable!</p> <pre><code> private Socket connection; private PrintWriter outStream; private Scanner inStream; public void InitiateConnection() throws IOException { log.Info(this, "Initiating connection to host: " + host + ":" + port); connection = new Socket(host, port); log.Info(this, "Connection initiated."); outStream = new PrintWriter(connection.getOutputStream(), true); inStream = new Scanner(connection.getInputStream()); Listen(); Listen(); Listen(); } public String Listen() throws IOException { if(connection == null) throw new IOException("Connection not initiated yet"); String response = inStream.nextLine(); log.Info(this, "Response: " + response); return response; } </code></pre> <p>This is the simple setup, I have left out all other code, as it doesn't have anything to do with my problem.</p> <p>I have tried multiple things to try to achieve this. Failed Solution 1:</p> <pre><code>String response = ""; while(response != null) Listen(); </code></pre> <p>Failed Solution 2:</p> <pre><code>while(connection.getInputStream().available &gt; 0) Listen(); </code></pre> <p>And countless others... But either it doesn't work, or the methods block and wait for new input. I have even tried with a timeout, but that doesn't work flawlessly either, its not a proper solution to this problem...</p> <p>I need to be able to get the entire welcome message from the FTP server, without knowing the amount of lines... So I can both get this:</p> <pre><code>Response: 220-FileZilla Server version 0.9.39 beta Response: 220-written by Tim Kosse (Tim.Kosse@gmx.de) Response: 220 Please visit http://sourceforge.net/projects/filezilla/ </code></pre> <p>And this:</p> <pre><code>Response: 220-FileZilla Server version 0.9.40 beta Response: 220 Welcome to Andrés FTP Server </code></pre>
