Subject: Bug in ncftp passive mode handling?

>From the man page in ncftp:

       -P     toggle passive mode (defaults to on).   Useful  for
              work behind firewalls.

This tells me that it's ON by default, so ncftp without -P should be
passive, right?

Hmmmmm!  Well, sitting here behind the cisco firewall:

chein-as-pc1 {911}# ncftp ftp://freebsd.org/pub/FreeBSD/packages/editors
NcFTP 1.9.4 (April 15, 1995) by Mike Gleason, NCEMRSoft.
Tip: Don't put a site in your .ncftprc unless you want an 'init' macro.  The 
     recent-file saves sites with the last directory you were in, unlike 
     the rc file, while still letting you use sitename abbreviations.
freebsd.org:/pub/FreeBSD/packages/editors
(Mail) ncftp>ls
<eternal hang characteristic of passive negotiation failure>

So then we try it with -P:

chein-as-pc1 {916}# ncftp -P ftp://freebsd.org/pub/FreeBSD/packages/editors
NcFTP 1.9.4 (April 15, 1995) by Mike Gleason, NCEMRSoft.
Tip: You can put set commands in your .ncftprc, by adding lines such
     as '#set local-dir /usr/tmp' to the file, which will be run at startup.
freebsd.org:/pub/FreeBSD/packages/editors
(Mail) ncftp>ls
aXe-6.1.2.tgz@          mule-2.2.2.tgz@         xhtml-dynamic.tgz@
emacs-19.28.tgz@        vile-5.2.tgz@           xhtml-static.tgz@
jove-4.16b.tgz@         xemacs-19.11.tgz@       xvile-5.2.tgz@
freebsd.org:/pub/FreeBSD/packages/editors
(Mail) ncftp>

Works fine!

Our standard ftp doesn't default to passive mode either - you
need to do a `passive' command first.

What's the concensus on this?  libftp, BTW, doesn't appear to handle
passive mode _at all_!  Oh well, so much for that particular option
in the install.. :-(
