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.
