Gee, I just tweaked the 4.3-tahoe "ftpd" to put out a 3-line greetings
banner, according to the specs in the FTP RFC, set it up as the FTP
daemon on my 4.0.1 Sun-3, and connected to it with the vanilla FTP
client on the same machine - said client had no problem at all with it. 
Perhaps upgrading from a 4.2-derived FTP client to a 4.3-derived FTP
client in SunOS 4.0 did the trick?

If so, this means:

	1) Sun's *already* fixed their machines in 4.0 (if you're running
	   3.x, you might consider bringing up the 4.3BSD FTP client on it,
	   bearing in mind that it may either depend on 4.3BSD features
	   in the local OS or on added commands in the 4.3BSD server
	   implementation);

	2) any other vendor whose FTP client is 4.2BSD-derived may have
	   the same problem, if the problem was introduced by Berkeley
	   and not Sun.
