Probably because the firewall hasn't been set up to allow ftp.exe as a
listening program.

FTP has two modes of operation - passive and active. The command-line FTP
client in Windows (and, let's face it, pretty much every other operating
system) uses active mode, which means that the FTP server must connect to
the FTP client on a random port that the FTP client sends to the server.

Try turning on debug (ftp -d) to view what commands are sent to the server,
to see what I'm talking about.

Alun.

Re: FTP DIR Hangs in Vista

Thanks for you help. I checked and my firewall service in Vista is not
started so I assume that can't be the problem. I agree, however, that it
seems like a firewall problem. I also tried using debug mode and passive
mode. I wasn't sure how to enable passive mode but I think I did it by
sending the "PASV" command to the other server by using "Quote PASV" command.
Unfortunately, It still hangs (see below) in passive mode.

Ftp

(hangs indefinetely at this point - must ctrl-c out)

That's because "quote pasv" is not enough to do passive mode. When you sent
that command, you received back an IP address and port (66,240,31,227,5,97)
that the server was listening on, and then you went ahead and tried your
transfer in active mode anyway (that's what the PORT command does - tell the
server that you've changed your mind and want to do active mode transfers
again).

You should try fetching another FTP client, that can be configured to use
passive mode for data transfers, and see if it works.

Alun.
