This user is having a problem with passive ftp, and the fact that these
ftp servers try to redirect to a random port once data starts transfer.
Often this is blocked by a firewall. Thus you connect, but when doing a
ls or dir, your session locks up.
Fabiano: I would refer to your firewall vendor's site or support. I have
seen this with v4 of FW-1, and there are several workarounds at
www.phoneboy.com.
BTW, IMHO, the original reply on the tag of this message is flippant,
and not in the least informative. This condescension is hardly the way
to respond to this guy's legitimate question, and, in fact, it is
obvious that this person even didn't understand the problem!
Maybe someone else on this list will have some additional information
(not diatribe) to contribute.

There's nothing strange about that.

Yes, it is right. You should read: http://www.faqs.org/rfcs/rfc959.html
You can find Howtos on what to do on the Internet.
