"xinetd - extended Internet services daemon - provides a good security
against intrusion and reduces the risks of Deny of Services (DoS)
attacks. Like the well known couple (inetd+tcpd), it allows to fix the
access rights for a given machine, but it can do much more. In this
article we will discover its many features."
Hmmm... Some interesting features in this one. Here's a good one:
binding a service to a specific interface, so one could have an ftp/telnet server
available for a private network, but not for the public network.
This article also briefly covers what inetd is, so it's worth reading the first couple
of paragraphs if you don't know. It then goes on to specify the features of xinetd
(no it's not an X program), installation and configuration. xinetd is included in
redhat 7. They recommend using xinetd for public access machines, while it's not
worth the extra administration on internal computers.
