Has anyone run into an ftp server which is not happy talking passive to
NetBSD-1.4.2+ ?

A 1.4 box of mine will happily do this:
ftp ftp://ftp.mysql.com/MySQL-3.22/mysql-3.22.32.tar.gz
Connected to ftp.mysql.com.
220 ProFTPD 1.2.0pre10 Server (MySQL at the Matrix) [cpu33]
331 Anonymous login ok, send your complete e-mail address as password.
230 Anonymous access granted, restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.
200 Type set to I.
250 CWD command successful.
local: mysql-3.22.32.tar.gz remote: mysql-3.22.32.tar.gz
227 Entering Passive Mode (64,28,67,70,0,0)
200 PORT command successful.
150 Opening BINARY mode data connection for mysql-3.22.32.tar.gz (4295387 bytes).
  4% |** 
[successful completion]

But 1.4.2 and 1.5ALPHA give:
Connected to ftp.mysql.com.
220 ProFTPD 1.2.0pre10 Server (MySQL at the Matrix) [cpu33]
331 Anonymous login ok, send your complete e-mail address as password.
230 Anonymous access granted, restrictions apply.
Remote system type is UNIX.
Using binary mode to transfer files.
200 Type set to I.
250 CWD command successful.
local: mysql-3.22.32.tar.gz remote: mysql-3.22.32.tar.gz
227 Entering Passive Mode (64,28,67,70,0,0)
500 Illegal PORT command.

Active ftp works fine from both machines. Am I missing something obvious?
