securenet -- ypserv(8) configuration file for secure networks DESCRIPTION
The securenet file controls which hosts can connect to the YP server. The format is rather simple. Each row consists of two items. The first item is the network mask. The second item is the network. EXAMPLES
A configuration file might appear as follows: # # Only my local net is secure. # FILES

securenets - configuration file for NIS security SYNOPSIS
/var/yp/securenets DESCRIPTION
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: o Lines beginning with the ``#'' character are treated as comments. o Otherwise, each line contains two fields separated by white space. The first field is a netmask, the second a network. o The netmask field may be either (IPv4), ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff (IPv6) , or the string ``host'' indi- cating 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: hosts EXAMPLES
Example 1: Access for Individual Entries If individual machines are to be give access, the entry could be: or host Example 2: Access for a Class C Network If access is to be given to an entire class C network, the entry could be: Example 3: Access for a Class B Network The entry for access to a class B network could be: Example 4: Access for an Invidual IPv6 Address Similarly, 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: Access for all IPv6 Addresses Starting with fe80 To allow access for all IPv6 addresses starting with fe80: ffff:: fe80:: FILES
