pam_rhosts


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.
