In addition to the resolver file and the host name data base,
three other files are available to allow you to configure additional
information about your network. Each of these files is provided
in sample format in the NET.SYS account. Each sample file contains an explanation
of the format for the data and a sample entry. The available files
and their functions are described as follows.
Network Name Database |
 |
The network name database, NETWORKS.NET.SYS, associates IP addresses with official network
names and aliases. This allows the user to refer to a network by
a symbolic name instead of an internet address. To configure the
network name database, modify the sample file NETSAMP.NET.SYS.
Protocol Name Database |
 |
The
protocol name database PROTOCOL.NET.SYS, associates protocol numbers with official protocol
names and aliases. This allows the user to refer to a protocol by
a symbolic name instead of a number. The protocol number mappings
are defined in RFC 1010 Assigned Numbers. To
configure the protocol name database, modify the sample file
PROTSAMP.NET.SYS (this is required for FTP use, starting in release
6.0).
Service Name Database |
 |
The service name database, SERVICES.NET.SYS, associates official service names and aliases
with the port number and protocol the services use. Reserved port
numbers 0 through 255 are assigned by RFC 1010. To configure the
service name database, modify the sample file SERVSAMP.NET.SYS.
