hosts.equiv  -  list  of  hosts  and users that are granted "trusted" r
   command access to your system


   The file /etc/hosts.equiv allows or denies hosts and users to  use  the
   r-commands (e.g., rlogin, rsh, or rcp) without supplying a password.

   The file uses the following format:


   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  explicitly  deny  access  to a host by preceding the hostname by a
   minus (-) sign.  Users from that host  must  always  supply  additional
   credentials,  including  possibly  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
   typographical  error  could  result  in  a  standalone  plus  sign.   A
   standalone plus sign is a wildcard character that means "any host"!




   Some systems will honor the contents of this  file  only  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.

   Modern  systems use the Pluggable Authentication Modules library (PAM).
   With PAM a standalone plus sign  is  considered  a  wildcard  character
   which  means  "any host" only when the word promiscuous is added to the
   auth component line in your PAM file for the particular service  (e.g.,


   Below are some example /etc/host.equiv or ~/.rhosts files.

   Allow any user to log in from any host:


   Allow any user from host with a matching local account to log in:


   Note: the use of +host is never a valid syntax, including attempting to
   specify that any user from the host is allowed.

   Allow any user from host to log in:

       host +

   Note: this is distinct from the previous  example  since  it  does  not
   require a matching local account.

   Allow user from host to log in as any non-root user:

       host user

   Allow all users with matching local accounts from host to log in except
   for baduser:

       host -baduser

   Deny all users from host:


   Note: the use  of  -host -user  is  never  a  valid  syntax,  including
   attempting  to  specify  that  a  particular  user from the host is not

   Allow all users  with  matching  local  accounts  on  all  hosts  in  a


   Disallow all users on all hosts in a netgroup:


   Allow all users in a netgroup to log in from host as any non-root user:

       host +@netgroup

   Allow all users with matching local accounts on all hosts in a netgroup
   except baduser:

       +@netgroup -baduser

   Note: the deny statements must  always  precede  the  allow  statements
   because  the  file  is  processed sequentially until the first matching
   rule is found.
