PAM_RHOSTS(8)                                           Linux-PAM Manual                                           PAM_RHOSTS(8)



NAME
       pam_rhosts - The rhosts PAM module

SYNOPSIS
       pam_rhosts.so

DESCRIPTION
       This module performs the standard network authentication for services, as used by traditional implementations of rlogin
       and rsh etc.

       The authentication mechanism of this module is based on the contents of two files; /etc/hosts.equiv (or and ~/.rhosts.
       Firstly, hosts listed in the former file are treated as equivalent to the localhost. Secondly, entries in the user's own
       copy of the latter file is used to map "remote-host remote-user" pairs to that user's account on the current host. Access
       is granted to the user if their host is present in /etc/hosts.equiv and their remote account is identical to their local
       one, or if their remote account has an entry in their personal configuration file.

       The module authenticates a remote user (internally specified by the item PAM_RUSER connecting from the remote host
       (internally specified by the item PAM_RHOST). Accordingly, for applications to be compatible this authentication module
       they must set these items prior to calling pam_authenticate(). The module is not capable of independently probing the
       network connection for such information.

OPTIONS
       debug
           Print debug information.

       silent
           Don't print informative messages.

       superuser=account
           Handle account as root.

MODULE TYPES PROVIDED
       Only the auth module type is provided.

RETURN VALUES
       PAM_AUTH_ERR
           The remote host, remote user name or the local user name couldn't be determined or access was denied by .rhosts file.

       PAM_USER_UNKNOWN
           User is not known to system.

EXAMPLES
       To grant a remote user access by /etc/hosts.equiv or .rhosts for rsh add the following lines to /etc/pam.d/rsh:

           #%PAM-1.0
           #
           auth     required       pam_rhosts.so
           auth     required       pam_nologin.so
           auth     required       pam_env.so
           auth     required       pam_unix.so
