pam_rhosts - The rhosts PAM module
pam_rhosts.so
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.
