The procedure you have to follow in order to create an anonymous FTP site
is as follows :

1. Create an account called "ftp". Disable the account by placing an 
   asterisk (*) in the passwd field. Give the account a special home 
   directory, such as /usr/ftp or /usr/spool/ftp.

2. Make the home directory owned by "ftp" and unwritable by anyone:
     # chown ftp ~ftp
     # chown 555 ~ftp

3. Make the directory ~ftp/bin, owned by the super-user and unwritable by
   anyone. Place a copy of the ls program in this directory:
     # mkdir ~ftp/bin
     # chown root ~ftp/bin
     # chmod 555 ~ftp/bin
     # cp -p /bin/ls ~ftp/bin
     # chmod 111 ~ftp/bin/ls

4. Make the directory ~ftp/etc, owned by the super-user and unwritable by
   anyone. Place copies f the password and group files in this directory,
   with all the password fields changed to asterisks (*). You may wish to
   delete all but a few of the accounts and groups of these files; the
   only account that must be present is "ftp".
     # mkdir ~ftp/etc
     # chown root ~ftp/etc
     # chmod 555 ~ftp/etc
     # cp -p /etc/passwd /etc/group ~ftp/etc
     # chmod 444 ~ftp/etc/passwd ~ftp/etc/group

5. Make the directory ~ftp/pub, owned by "ftp" and world-writable. Users 
   may then place files that are to be accessible via anonymous FTP in this
   directory:
     # mkdir ~ftp/pub
     # chown ftp ~ftp/pub
     # chmod 777 ~ftp/pub
