5 5 NAME
6 6 securenets - configuration file for NIS security
7 7
8 8 SYNOPSIS
9 9 /var/yp/securenets
10 10
11 11
12 12 DESCRIPTION
13 13 The /var/yp/securenets file defines the networks or hosts which are
14 14 allowed access to information by the Network Information Service
15 15 ("NIS").
16 16
17 17
18 18 The format of the file is as follows:
19 19
20 20 o Lines beginning with the ``#'' character are treated as
21 21 comments.
22 22
23 23 o Otherwise, each line contains two fields separated by white
24 24 space. The first field is a netmask, the second a network.
25 25
26 26 o The netmask field may be either 255.255.255.255 (IPv4),
27 27 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff (IPv6) , or the
28 28 string ``host'' indicating that the second field is a
29 29 specific host to be allowed access.
30 30
31 31
32 32 Both ypserv(1M) and ypxfrd(1M) use the /var/yp/securenets file. The
33 33 file is read when the ypserv(1M) and ypxfrd(1M) daemons begin. If
34 34 /var/yp/securenets is present, ypserv(1M) and ypxfrd(1M) respond only
35 35 to IP addresses in the range given. In order for a change in the
36 36 /var/yp/securenets file to take effect, you must kill and restart any
37 37 active daemons using ypstop(1M) and ypstart(1M).
38 38
39 39
40 40 An important thing to note for all the examples below is that the
41 41 server must be allowed to access itself. You accomplish this either by
42 42 the server being part of a subnet that is allowed to access the server,
43 43 or by adding an individual entry, as the following:
44 44
45 45 hosts 127.0.0.1
46 46
47 47
48 48
49 49 EXAMPLES
50 50 Example 1 Access for Individual Entries
51 51
52 52
53 53 If individual machines are to be give access, the entry could be:
54 54
55 55
56 56 255.255.255.255 192.9.1.20
57 57
58 58
59 59
60 60
61 61 or
62 62
63 63
64 64 host 192.0.1.20
65 65
66 66
67 67
68 68 Example 2 Access for a Class C Network
69 69
70 70
71 71 If access is to be given to an entire class C network, the entry could
72 72 be:
73 73
74 74
75 75 255.255.255.0 192.9.1.0

79 79 Example 3 Access for a Class B Network
80 80
81 81
82 82 The entry for access to a class B network could be:
83 83
84 84
85 85 255.255.0.0 9.9.0.0
86 86
87 87

89 - Example 4 Access for an Invidual IPv6 Address
89 + Example 4 Access for an Individual IPv6 Address
90 90
91 91
92 92 Similarly, to allow access for an individual IPv6 address:
93 93
94 94
95 95 ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff fec0::111:abba:ace0:fba5e:1
96 96
97 97
98 98
99 99
100 100 or
101 101
102 102
103 103 host fec0::111:abba:ace0:fba5e:1
104 104
105 105
106 106
107 107 Example 5 Access for all IPv6 Addresses Starting with fe80
108 108
109 109
110 110 To allow access for all IPv6 addresses starting with fe80:
111 111
112 112
113 113 ffff:: fe80::
