... because there is no EPSV support in ncftp3 . . .

Reading rfc2428 may get a bit confusing at times . . .

It also says:

"...
 If an extended command fails then this option will be temporarily
disabled for the duration of the current connection, or until epsv4 is
executed again.
..."

And it *looks* like the timeout to recognize such a failure is
somewhat long. I just found out that connection to one of my ftp
servers from outside fails from time to time if there is no 'epsv4
off' command; usually it fails first time, then after a session
restart it will succeed, but with some minute timeout.
