12 /etc/hosts.equiv - list of hosts and users that are granted r__ command access to your system
13 !!DESCRIPTION
14
15
16 The __hosts.equiv__ file allows or denies hosts and users
17 to use the __r__-commands (e.g. __rlogin__, __rsh__
18 or __rcp__) without supplying a password.

21 The file uses the following format:
22
23
24 ''[[ + | - ] [[hostname] [[username]''
25
26
27 The ''hostname'' is the name of a host which is logically
28 equivalent to the local host. Users logged into that hosts
29 are allowed to access like-named user accounts on the local
30 host without supplying a password. The ''hostname'' may
31 be (optionally) preceded by a plus (+) sign. If the plus
32 sign is used alone it allows any host to access your system.
33 You can expicitly deny access to a host by preceding the
34 ''hostname'' by a minus (-) sign. Users from that host
35 must always supply a password. For security reasons you
36 should always use the FQDN of the hostname and not the short
37 hostname.

40 The ''username'' entry grants a specific user access to
41 all user accounts (except root) without supplying a
42 password. That means the user is NOT restricted to
43 like-named accounts. The ''username'' may be (optionally)
44 preceded by a plus (+) sign. You can also explicitly deny
45 access to a specific user by preceding the ''username''
46 by a minus (-) sign. This says that the user is not trusted
47 no matter what other entries for that host
48 exist.
49
50
51 Netgroups can be specified by preceding the netgroup by an @
52 sign.
53
54
55 Be extremely careful when using the plus (+) sign. A simple
56 typographical error could result in a standalone plus sign.
57 A standalone plus sign is a wildcard character that means

65 Some systems will only honor the contents of this file when
66 it has owner root and no write permission for anybody else.
