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
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.
