- configuration file for NIS security
/var/yp/securenets
The /var/yp/securenets file defines the networks or hosts which are allowed access to information by the Network Information Service (“NIS”).
The format of the file is as follows:
Lines beginning with the ``#'' character are treated as comments.
Otherwise, each line contains two fields separated by white space. The first field is a netmask, the second a network.
The netmask field may be either 255.255.255.255 (IPv4), ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff (IPv6) , or the string ``host'' indicating that the second field is a specific host to be allowed access.
Both ypserv(1M) and ypxfrd(1M) use the /var/yp/securenets file. The file is read when the ypserv(1M) and ypxfrd(1M) daemons begin. If /var/yp/securenets is present, ypserv(1M) and ypxfrd(1M) respond only to IP addresses in the range given. In order for a change in the /var/yp/securenets file to take effect, you must kill and restart any active daemons using ypstop(1M) and ypstart(1M).
An important thing to note for all the examples below is that the server must be allowed to access itself. You accomplish this either by the server being part of a subnet that is allowed to access the server, or by adding an individual entry, as the following:
host 127.0.0.1
Example 1 Giving Access for Individual Machines
If individual machines are to be given access, the entry could be:
255.255.255.255 192.9.1.20
or
host 192.0.1.20
Example 2 Giving Access to an Entire Class C Network
If access is to be given to an entire class C network, the entry could be:
255.255.255.0 192.9.1.0
Example 3 Giving Access to a Class B Network
If access is to be given to a class B network, the entry could be:
255.255.0.0 9.9.0.0
Example 4 Giving Access for an Individual IPv6 Address
To allow access for an individual IPv6 address:
ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff fec0::111:abba:ace0:fba5e:1
or
host fec0::111:abba:ace0:fba5e:1
Example 5 Giving Access for all IPv6 Addresses Starting with fe80
To allow access for all IPv6 addresses starting with fe80:
ffff:: fe80::
Configuration file for NIS security.

The Network Information Service (NIS) was formerly known as Sun Yellow Pages (YP). The functionality of the two remains the same; only the name has changed.
