Perhaps there was a typo in one of your config files (manually edited?) 
which was now corrected by running nwconfig?  Or the interface was 
disabled manually for some reason.

This is called "chrooting" the user.  It is done by changing the home 
directory for users as listed in the /etc/passwd file.  For example if 
you have:

ralphs:x:500:500:Ralph Siemsen:/home/ralphs:/bin/bash

To make so I cannot go outside of my home directory, we introduce an 
extra /./ into the home directory location, like so:

ralphs:x:500:500:Ralph Siemsen:/home/ralphs/./:/bin/bash

The /./ can appear anywhere in the path, not just the end, and will 
limit the user to being in that directory and below.

I can't remember if there were changes required in the wu-ftpd config 
file as well.  It may be necessary to put users into "guest" group for 
th above to work.  Consult the man pages for wuftpd and its config file.
