Re: Net::FTP port inconsistencies

It's almost certainly a firewall issue, either at the linux oir windows end. Try putting the ftp client into passive mode - that usually resolves most such issues. When not in passive mode, ftp requires a second data conncection to be established from a ramdom port on the server to a random port on the client, which generally gets blocked by stateless firewalls.

Hi Dave, Thanks for your reply. We already use passive mode as indicated by the code below: `my $ftp = Net::FTP->new($self->{HOSTNAME}, "Firewall" => "", "Port" => 21, "Debug" => 0, "Passive" => 1);` [download] I just tried creating an FTP connection from the linux command line and I get the same problem, i.e. I can login and move to the relevant directory but the put command times out. Perhaps, this is a setting on the linux server?? rgds Conor	[reply] [d/l]

In passive mode, the data connection is initiated by the cleint, so it is likely to be the firewall on the server which is too strict. I'm too sure about the `"Firewall" => ""`; I'm not sure whether a blank proxy name acts the same as no proxy; you might want to comment out that line and see if it makes any difference (but it probably won't). A final suggestion would be to use sftp if possible - it's a lot more firewall friendly! Dave.	[reply] [d/l]
