16 15 .SH DESCRIPTION
17 -.sp
18 -.LP
19 16 The \fB/var/yp/securenets\fR file defines the networks or hosts which are
20 17 allowed access to information by the Network Information Service ("\fBNIS\fR").
21 18 .sp
22 19 .LP
23 20 The format of the file is as follows:
24 21 .RS +4
25 22 .TP
26 23 .ie t \(bu
27 24 .el o
28 25 Lines beginning with the ``#'' character are treated as comments.
29 26 .RE
30 27 .RS +4
31 28 .TP
32 29 .ie t \(bu
33 30 .el o
34 31 Otherwise, each line contains two fields separated by white space. The first
35 32 field is a netmask, the second a network.
36 33 .RE
37 34 .RS +4
38 35 .TP
39 36 .ie t \(bu
40 37 .el o
41 38 The netmask field may be either \fB255.255.255.255\fR (IPv4),
42 39 \fBffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff\fR (IPv6) , or the string ``host''
43 40 indicating that the second field is a specific host to be allowed access.

46 43 .LP
47 44 Both \fBypserv\fR(1M) and \fBypxfrd\fR(1M) use the \fB/var/yp/securenets\fR
48 45 file. The file is read when the \fBypserv\fR(1M) and \fBypxfrd\fR(1M) daemons
49 46 begin. If \fB/var/yp/securenets\fR is present, \fBypserv\fR(1M) and
50 47 \fBypxfrd\fR(1M) respond only to \fBIP\fR addresses in the range given. In
51 48 order for a change in the \fB/var/yp/securenets\fR file to take effect, you
52 49 must kill and restart any active daemons using \fBypstop\fR(1M) and
53 50 \fBypstart\fR(1M).

56 53 An important thing to note for all the examples below is that the server must
57 54 be allowed to access itself. You accomplish this either by the server being
58 55 part of a subnet that is allowed to access the server, or by adding an
