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.

~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
	tcp	# needed so the socket call within ftp can work.
	udp	# probably not needed, but I added it when I added tcp
~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.
shlib:
total 54
-rwxr-xr-x   1 root     other      26236 Feb 27 10:47 libc_s*

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