Xinetd

Uses global /etc/xinetd.conf file and per-service /etc/xinetd.d/* files.

Allows much finer-grained control of services
Allow services based on IP address, ala TCP Wrappers
Allow services based on time
Configurable logging
syslog vs file
pid / host / userid / exit time / duration
Number of concurrent services
Process limits (cpu, address space, etc)
Supplimental groups
Umask
Banners on connect, success, or failure
Defaults are inherited, can be overridden, supplemented, or abridged
Services can be easily disabled with 'disable' directive
