> Hi,
> If executing the following code
> String hostname = "localhost";
> FTPClient client = new FTPClient();
> client.setDefaultTimeout(1000);
> client.connect(hostname);
> against a ftp server that ignores the connection attempt (e.g. is firewalled/malfunctoned), there will be no exception after 1000 ms. The exception will be thrown after a default timeout of three minutes. (Three minutes on a debian/ and a suse machines. Might be different on other platforms).
> JavaDoc says:
> public void setDefaultTimeout(int timeout)
> Set the default timeout in milliseconds to use when opening a socket.
> Digging through the code I found, that DefaultSocketFactory which is used be SocketClient does not care about any value set with this method. It creates a new Socket with Socket(hostname, port) and relies on the VMs behaviour.
> To get this fixed I set a custom SocketFactory with client.setSocketFactory(socketFactory); that uses a timeout for socket connection.
> This bug is also in 1.4.1, but this value is not listed...
