http://linuxexchange.org/questions/103/slow-ftp-loginauthentication<p>Hi all, When I'm trying to login to the ftp server with appropriate username and password its taking almost 10-15 seconds to authenticate making the login process slow, even when I'm uploading files its again hanging for 10-15 seconds before completing the job successfully. Its not like its happening every time, but 7 times out of 10. Any idea how can make the authentication fast?</p> <p>I'm using gftp to connect to the ftp server, while connecting it hangs after showing this message:</p> <pre><code>Quote:gFTP 2.0.19, Copyright (C) 1998-2008 Brian Masney &lt;masneyb@gftp.org&gt;.
