Applying restrictions to anonymous ftp-ers

[Michael Regoli]

][

When logging into many hosts allowing anonymous ftp access, the
message "Guest login ok, access restrictions apply" appears upon a
successful login.  However, it remains to be seen what restrictions
are in effect.  For example, in a public uploads area (owned by ftp,
mode 777), ftp users can "put" and "get" files, in addition to "dele"
and "append" to files.  It is the latter cases that oftentimes
destroys data in a public area.

What measures can be applied via BSD ftpd to restrict access to
certain ftp commands?  More specifically, how can files in a public
area be "protected" (*and* still remain public) from damage by other
anonymous ftp-ers?  (Thankfully ftp won't allow files to "collide"
that have the same name.)
 
Thanks for any help...
