The rhosts PAM module
' pam_rhosts.so 'u 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 (Aqs own copy of the latter file is used to map " remote-host remote -user "pairs to that user (Aqs 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 .
debug Print debug information .
silent Don (Aqt print informative messages .
superuser= account Handle account as root .
Only the auth module type is provided .
PAM_AUTH_ERR The remote host, remote user name or the local user name couldn (Aqt be determined or access was denied by .rhosts file .
PAM_USER_UNKNOWN User is not known to system .
To grant a remote user access by /etc/hosts .equiv or .rhosts for rsh add the following lines to /etc/pam .d/rsh:.RS 4
