I used the account 'ftp' since it wouldn't have the problem.  With
this, both 'anonymous' and 'ftp' work as logins.

I had the same problem.  It doesn't tell you that there are a few
other files thatyou need to have in the ~ftp account.  This is
for Interactive Systems 2.0.2, your mileage may vary.

~ftp/bin
	ls	needed for the NLST or LIST commands in ftp to work.
	pwd	needed to get the current working directory

~ftp/dev
	null	# may not be needed, but I added it while trying to fix
		# the problem.
	tcp	# needed so the socket call within ftp can work.
	udp	# probably not needed, but I added it when I added tcp

	Note that these files in the ~ftp/dev directory will need to
	be actual devices.  Therefore, you will need to either link
	to the real /dev/* files, or use mknod to create them.

~ftp/etc
	group	# needed for group id to show up in the dir command.
	passwd	# needed for login id to show up in the dir commadn.

~ftp/shlib
	libc_s	# surprise, /bin/ls uses the shared library so this 
		# is requried.

ftpd will automatically do a chroot to the new directory, thus
preventing you from using CD to get to directories above ~ftp.
