If you are using debian 2.1 (slink) you should download the versions above, or more recent versions if available. Note that wu-ftpd will install in a disabled state on some configurations; you can enable wu-ftpd by uncommenting the line for /usr/sbin/ftpd in /etc/inetd.conf and running "/etc/init.d/netbase reload". The line for /usr/sbin/in.ftpd should remain disabled.
