Net::FTP::Recursive hangs

[bill]

Hi All,

I'm trying to use Net::FTP::Recursive 'rdir' to return recursive
directory listings.
I tried both my own version of a script, and when that did not work, I
tried the script
included in the 2.0 version of Net::FTP::Recursive. I turned on Debug,
and here is the
output (same for both scripts). The script hangs on LIST, then times
out after a few minutes.
I've ftp'ed directory to this site and verified that the directory is
there and has
sub-directories. I've done a little searching for info on the 425 eror
msg, but did not find much useful. I'm running this on Mac OS/X 10.4.8,
perl 5.8.6, Net::FTP::Recursive 2.0.

Can someone help?

Thanks, Bill

"Ftp hangs on LIST command" is 99% of the time related to NAT. Did you do
the ftp from the same box? Does that client have any proxy settings?

Hi Martin,
thanks for your reply.
Yes, ftp works fine on the same box from the command line:

I do use the firewall, with ftp passive mode ON. I do not have any
proxy servers defined (that I'm aware of). None are set in the network
manager.

Thanks, Bill

I found the problem. I needed to set the 'Passive => 1' flag in the
new() cmd.
Martin, thanks for pointing me in the right direction.
