RHOSTS(SFF)                                UNIX System V



     Name
          rhosts - remote equivalent users


     Description
          These files grant permission for remote users to  use  local
          user names without knowing the corresponding user passwords.
          This is known as making the remote  user  ``equivalent''  to
          the  local  user,  and  is convenient, for example, when one
          person owns user names on more than one host.

          If a user's home directory contains a  file  named  .rhosts,
          remote  users  specified  in  the file are equivalent to the
          local user.  Each user specification in the file consists of
          the  remote  user  host  name  and user name, separated by a
          space.  (If an asterisk is substituted for either name,  any
          name  will match.) For security reasons, .rhosts must belong
          to the user granting the equivalence or to root.

          The file /etc/hosts.equiv is a list  of  remote  hosts  with
          matching-name  equivalence.  The file lists remote hosts one
          per line.  On each host listed in /etc/hosts.equiv, a remote
          user with the same name as a local user is equivalent to the
          local user.  In effect, the users are the same if the  names
          are the same.


     Files
          $HOME/.rhosts
          /etc/hosts.equiv

     Warnings
          When a system is listed in  /etc/hosts.equiv,  its  security
          must  be  as  good  as  local security.  One insecure system
          mentioned in /etc/hosts.equiv can compromise the security of
          an entire network.
