tcpd is the daemon for the tcp wrapper mechanism that controls who can
connect and logging.

How does tcpd work? How does it make inetd`s services more secure?
How does it work together with inetd`s replacement: xinetd
Thanks,
Raul

without tcpd (tcp wrappers) anyone can connect to services you provide via inetd or xinetd. well, they can attempt to connect. say for instance you have an imap server and you are not running tcpd. well anyone can telnet to port 143 on the system (provided you dont have a firewall or some type of packet filter in place) and try username/passwords till they get in. with tcpd in place, you can restrict which hosts are allowed to connect to which services through the use of two files /etc/hosts.allow and /etc/hosts.deny.
