1/15    When I download a large file via ftp, my router/NAT keep closing the
        control connection.  Is there a way to keepalive from the client side?
        \_ Passive FTP or SCP, if you can.  Otherwise consider tunneling
           the FTP over an SSH session if that is an option.  Of course if
           your router just generally times out sessions after x minutes with
           no regard to source/destination, you're SOL.  -John
