/etc/hosts.equiv - list of hosts and users that are
granted "trusted" r command access to your system
DESCRIPTION
The hosts.equiv file allows or denies hosts and users to
use the r-commands (e.g. rlogin, rsh or rcp) without sup
plying a password.
The file uses the following format:
[ + | - ] [hostname] [username]
The hostname is the name of a host which is logically
equivalent to the local host. Users logged into that hosts
are allowed to access like-named user accounts on the
local host without supplying a password. The hostname may
be (optionally) preceded by a plus (+) sign. If the plus
sign is used alone it allows any host to access your sys
tem. You can expicitly deny access to a host by preceding
the hostname by a minus (-) sign. Users from that host
must always supply a password. For security reasons you
should always use the FQDN of the hostname and not the
short hostname.
The username entry grants a specific user access to all
user accounts (except root) without supplying a password.
That means the user is NOT restricted to like-named
accounts. The username may be (optionally) preceded by a
plus (+) sign. You can also explicitly deny access to a
specific user by preceding the username by a minus (-)
sign. This says that the user is not trusted no matter
what other entries for that host exist.
Netgroups can be specified by preceding the netgroup by an
@ sign.
Be extremely careful when using the plus (+) sign. A sim
ple typographical error could result in a standalone plus
sign. A standalone plus sign is a wildcard character that
means "any host"!

NOTE
Some systems will only honor the contents of this file
when it has owner root and no write permission for anybody
else. Some exceptionally paranoid systems even require
that there be no other hard links to the file.
