       The hosts.equiv file allows or denies hosts and users to use the r-com-
       mands (e.g. rlogin, rsh or rcp) without supplying 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 host 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 system.  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 with 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 simple typographi-
       cal error could result in a standalone plus  sign.  A  standalone  plus
       sign is a wildcard character that means "any host"!




       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


       rhosts(5), rshd(8), rlogind(8)
