pam_rhosts - The rhosts PAM module
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.
Print debug information.
Don't print informative messages.
Handle account as root.
