Configuring Database Files

TCP/IP Database Files
This appendix describes how the database files of the TCP/IP stack should be
configured.
TCP/IP uses four database files in the SYS:\ETC\directory to convert internal
data, such as IP addresses, into more identifiable and workable names.
HOSTS File (page 108)
NETWORKS File (page 109)
PROTOCOL File (page 110)
numbers
SERVICES File (page 111)
The user interface for TCPCON and other NLM files uses these database files.
To inform TCP/IP of names and addresses of local nodes and networks, you
must add that information to these files. The files are cached in memory so that
disk access is avoided during lookup. Because of this, TCP/IP takes up more
memory. If this is not desirable, keep the size of the database small or simply
delete the files.
TCP/IP finds the following four database files in the SYS:\ETC\directory:
These files are described in the sections following this discussion.
If you are configuring TCP/IP for the first time, we recommend that you start
by copying the sample database files from SYS:\ETC\SAMPLES to
SYS:\ETC. This provides you with some examples to refer to as you add your
own entries, and also provides TCP/IP with the PROTOCOL and SERVICES
files.
maps hostnames to IP addresses
maps network names to network addresses
maps protocol names to IP protocol
maps service names to TCP and UDP ports
