.SH "NAME"
pam_rhosts \- The rhosts PAM module
.SH "SYNOPSIS"
.HP \w'\fBpam_rhosts\&.so\fR\ 'u
\fBpam_rhosts\&.so\fR
.SH "DESCRIPTION"
.PP
This module performs the standard network authentication for services, as used by traditional implementations of
\fBrlogin\fR
and
\fBrsh\fR
etc\&.
.PP
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 "\fIremote\-host remote\-user\fR" 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\&.
.PP
The module authenticates a remote user (internally specified by the item
\fIPAM_RUSER\fR
connecting from the remote host (internally specified by the item
\fBPAM_RHOST\fR)\&. Accordingly, for applications to be compatible this authentication module they must set these items prior to calling
\fBpam_authenticate()\fR\&. The module is not capable of independently probing the network connection for such information\&.
.SH "OPTIONS"
.PP
\fBdebug\fR
.RS 4
Print debug information\&.
.RE
.PP
\fBsilent\fR
.RS 4
Don\*(Aqt print informative messages\&.
.RE
.PP
\fBsuperuser=\fR\fB\fIaccount\fR\fR
.RS 4
Handle
\fIaccount\fR
as root\&.
.RE
.SH "MODULE TYPES PROVIDED"
.PP
Only the
\fBauth\fR
module type is provided\&.
.SH "RETURN VALUES"
.PP
PAM_AUTH_ERR
.RS 4
The remote host, remote user name or the local user name couldn\*(Aqt be determined or access was denied by
\&.rhosts
file\&.
.RE
.PP
PAM_USER_UNKNOWN
.RS 4
User is not known to system\&.
.RE
.SH "EXAMPLES"
.PP
To grant a remote user access by
/etc/hosts\&.equiv
or
\&.rhosts
for
\fBrsh\fR
add the following lines to
/etc/pam\&.d/rsh:
.sp
.if n \{\
.RS 4
.\}
.nf

#
