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.
