Setting up NIS

Preparing /etc/hosts.equiv

The /etc/hosts.equiv file does not have an equivalent NIS map. However, either the system administrator or the local administrator can add escape characters to it that reference the NIS hosts database.


WARNING: This creates a potential security risk if untrusted hosts have access to the network.

If hosts.equiv contains a single line with only the escape characters ``+:'' (plus sign and colon) in it, then anyone listed in the password database (whether in the local passwd file or, if the local passwd file contains a ``+:'', in the NIS map) can access the machine from any known host. Refer to the hosts.equiv(4tcp) manual page for more information.

Designating trusted groups allows for more control over logins. Trusted groups are described in the netgroup(4nis) manual page. NIS assumes that the trusted group name appearing after the ``+@'' or ``-@'' sign is a netgroup defined in the netgroups map.

If a machine's hosts.equiv file does not have escape characters, only the entries in the hosts.equiv file determine whether remote access is granted or denied; the NIS maps are not consulted.
