|
|
|
||
|
|
This module provides logdaemon style login access control based on
|
||
|
|
login names and on host (or domain) names, internet addresses (or
|
||
|
|
network numbers), or on terminal line names in case of non-networked
|
||
|
|
logins. Diagnostics are reported through <tt/syslog(3)/. Wietse
|
||
|
|
Venema's <tt/login_access.c/ from <em/logdaemon-5.6/ is used with
|
||
|
|
several changes by A. Nogin.
|
||
|
|
|
||
|
|
<p>
|
||
|
|
The behavior of this module can be modified with the following
|
||
|
|
arguments:
|
||
|
|
<itemize>
|
||
|
|
|
||
|
|
<item><tt>accessfile=/path/to/file.conf</tt> -
|
||
|
|
indicate an alternative <em/access/ configuration file to override
|
||
|
|
the default. This can be useful when different services need different
|
||
|
|
access lists.
|
||
|
|
|
||
|
|
</itemize>
|
||
|
|
|
||
|
|
<tag><bf>Examples/suggested usage:</bf></tag>
|
||
|
|
|
||
|
|
Use of module is recommended, for example, on administrative machines
|
||
|
|
such as <bf/NIS/ servers and mail servers where you need several accounts
|
||
|
|
active but don't want them all to have login capability.
|
||
|
|
|
||
|
|
For <tt>/etc/pam.d</tt> style configurations where your modules live
|
||
|
|
in <tt>/lib/security</tt>, start by adding the following line to
|
||
|
|
<tt>/etc/pam.d/login</tt>, <tt>/etc/pam.d/rlogin</tt>,
|
||
|
|
<tt>/etc/pam.d/rsh</tt> and <tt>/etc/pam.d/ftp</tt>:
|
||
|
|
|
||
|
|
<tscreen>
|
||
|
|
<verb>
|
||
|
|
account required /lib/security/pam_access.so
|
||
|
|
</verb>
|
||
|
|
</tscreen>
|
||
|
|
|
||
|
|
Note that use of this module is not effective unless your system ignores
|
||
|
|
<tt>.rhosts</tt> files. See the the pam_rhosts_auth documentation.
|
||
|
|
|
||
|
|
A sample <tt>access.conf</tt> configuration file is included with the
|
||
|
|
distribution.
