Yes, good point, and probably the only reliable alternative at this
time.  There's something subtle going on in the layers between Perl
and Open Transport and the interaction of that with external FTP
servers, but it's not reliably reproducable, in that you'll get
different amounts through with each try, and sometimes even succeed.
It seems to even depend on time dependent things like network load
(Sunday morning is usually a good time to Net::FTP from MacPerl.)  My
rules of thumb are basically that to Solaris it can't be trusted at
all, while to SunOS files less that 100k are usually a good bet to
make it through.  I haven't tried much with other types of servers.

If you turn on Net::FTP debugging, ($ftp = Net::FTP->new($host, Debug
=>1)), almost certainly you'll find that it's failing with a
"Connection reset by peer" error.  This seems to be a generic "the
remote has dumped the connection for some unknown reason".
