ftp under ISC 2.2 TCP/IP

[William Miskovetz]

I'm running Interactive's TCP/IP version 1.2 under ISC's 2.2 OS.
I am having trouble with ftp.  I'm just trying something simple 
like ftp localhost.  I get logged in ok, but when I try a command 
like ls I get:

ftp> ls
200 PORT command successful.
421 Service not available, remote server has closed connection

I've tried and I've tried but I'm still mystified.  I just can't
figure out what's not configured correctly (I'm assuming ubd).
rlogin works correctly to localhost as does rsh (just make sure you
use /usr/ucb/rsh instead of /bin/rsh :-) 

I'm using the loopback driver.  I have no ethernet cards installed.
It's either loopback or SLIP.  Using SLIP I get the same error.

Any suggestions or hints greatly appreciated.  Thanks.
