When you're running from cron(8) you get a very limited environment.
You won't get a tty assigned to you, and the $TERM environment
variable won't be set. That makes it difficult for ftp(1) to do any
of the screen control things you may be expecting.
Stuff like $FTP_PASSIVE_MODE, which is often set out of
/etc/login.conf, won't be configured either. Actually, on reflection
the symptoms you describe sound like ftp(1) active mode breakage to me
--- you tend to get that if you're running a firewall on the client
end of the ftp connection. Try using pftp(1) or equivalently,
supplying the '-p' flag on the ftp command line.
Cheers,
Matthew
