HP-UX Internet Services Administrator's Guide (May 2010)

ARPA services include the set of services developed by UCB for the Advanced Research
Projects Agency (ARPA): ftp and telnet. ARPA services are used to communicate
with HP-UX, UNIX®, and non-UNIX systems.
Berkeley services include the set of services developed by UCB to implement UCB
protocols: BIND, sendmail, finger, the rexec library, rcp, rlogin, remsh,
ruptime, rwho, and rdist. Berkeley Services are used to communicate with HP-UX
or other UNIX systems.
The Internet Services software also contains several other services: BOOTP, tftp,
rbootd, NTP, and DDFA.
We recommend that you also read the following books for more detailed technical and
conceptual information:

Restructuring of the InternetSrvcs Product
In earlier releases of HP-UX (prior to HP-UX 11i v2), the Internet Services suite of
products comprised InternetSrvcs and MailUtilities.
Starting with HP-UX 11i v3, the InternetSrvcs products are restructured into 11
products based on the product functionality. However, the MailUtilities product
is not modified. The restructured InternetSrvcs products are classified as required,
recommended, and optional. This new structure provides the flexibility to deselect the
recommended and optional products while installing the HP-UX 11i v3 operating
system, and to remove the recommended and optional products after installing the
HP-UX 11i v3 operating system. As a result, you need to install patches only for those
products that are installed on your system. This improves software manageability of
the system and security, and also reduces system downtime.
Table 1-1 describes the 11 products into which the InternetSrvcs product is
restructured and the MailUtilities product.
