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.
