Morning,

I've trying to use Net::FTP to programatically retrieve files from an FTP server. The program I've got logs in to the FTP server every 30 minutes or so, lists the directory contents, and then downloads any files it needs and closes the connection.

The issue I have is that the code runs continuously, and, after monitoring the ports that Net::FTP and IO::Socket::INET open, it eventually runs out of ports to listen on!

Net::FTP calls IO::Socket::INET like this:

my $sock = IO::Socket::INET->new( Listen    => 5,
                                  Proto     => 'tcp',
                                  Timeout   => $ftp->timeout,
                                  LocalAddr => $ftp->sockhost);

Which creates a listening socket on the next port available. However, it never re-uses the same port twice, so the port numbers go up, and up and up... Until eventually the code fails to be able to create a listen port.

Anyone got any ideas on what can be done about this??

Ta,

Julian
