The remaining network databases seldom need to be edited.
The networks database associates network names with network numbers, enabling some applications to use and display names rather than numbers. The networks database is based on information in the /etc/inet/networks file. It contains the names of all networks to which your network connects via routers.
The Solaris installation program sets up the initial networks database. The only time you need to update it is when you add a new network to your existing network topology.
The networks(4) man page contains full syntax information for /etc/inet/networks. Here is its basic format
network-name network-number nickname(s) # comment
network-name is the official name for the network.
network-number is the number assigned by the InterNIC.
nickname is any other name by which the network is known.
#comment is any kind of note you want to append to an entry in the file.
It is particularly important that you maintain the networks file. The netstat program uses the information in this database to produce status tables.
Example 4-9 shows a sample /etc/networks file:
#ident "@(#)networks 1.4 92/07/14 SMI" /* SVr4.0 1.1 */ # # The networks file associates Internet Protocol (IP) network numbers with network names.
