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

NAME         top

       pam_rhosts - The rhosts PAM module

SYNOPSIS         top


       pam_rhosts.so

DESCRIPTION         top

       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.
