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?

I'm using gftp to connect to the ftp server, while connecting it hangs after showing this message:

Common causes of such behavior are due to the server:

  1. trying to know who you really are through the ident protocol (rfc1413) but having a firewall or NAT blocking this traffic
  2. failing to get your DNS name (reverse DNS lookups)
  3. having a partly unavailable authentication service
