Basic setup
is only valuable on a system with a working server. Setting up a server is beyond the scope of this document, but in a nutshell:
wu-ftpd or a similar server must be installed. The anonftp package can also be helpful to enable anonymous .
The /etc/inetd.conf file should contain a line like:

# ftp   stream  tcp nowait  root    /usr/sbin/tcpd  in.ftpd -l -a

Uncomment the line by removing the # from the start of the line. If your system shipped with the line uncommented, treat it as a warning sign and comment out other services that you do not want. Restart /etc/inetd.conf. (Entering /etc/rc.d/init.d/inet restart at the command-line works on and similar systems.)
