>After running <B
CLASS="COMMAND"
>./configure</B

<TT
CLASS="FILENAME"
>check_samhain.pl</TT
>
in the subdirectory <TT
CLASS="FILENAME"

> of
the samhain distribution, which you can copy to the 
<SPAN
CLASS="APPLICATION"
>nagios</SPAN
> 
<TT
CLASS="FILENAME"
>libexec/</TT
> directory. Before doing so, 
you may want to edit the script to set the correct path to the 
<TT
CLASS="FILENAME"
>libexec/</TT
>
directory in the following line:</P
><PRE
CLASS="PROGRAMLISTING"
>use lib  "/usr/local/nagios/libexec" ;</PRE
><P
>The following recipe to use this script has been kindly provided by kiarna:</P
><P
>Nagios runs as user 'nagios'. However, in order to check the filesystem,
you typically want to run <SPAN
CLASS="APPLICATION"
>samhain</SPAN
> as 'root'.
You can use <SPAN
CLASS="APPLICATION"
>sudo</SPAN
> to fix this problem.
In your <TT
CLASS="FILENAME"
>/etc/sudoers</TT
> file, add the line:</P
><PRE
CLASS="PROGRAMLISTING"
> 
nagios ALL = NOPASSWD:/path/to/check_samhain</PRE
><P
>Next, add the service to the nagios file 
<TT
CLASS="FILENAME"
>objects/commands.cfg</TT
>:</P
><PRE
CLASS="PROGRAMLISTING"
> 
# 'check_samhain' command definition
define command{
command_name check_samhain
command_line /usr/bin/sudo -u root $USER1$/check_samhain -t 100
}</PRE
><P
>Another option would be to install the check_samhain script with SUID
permissions instead of using sudo (this requires that the suidperl 
package is installed and
that <SPAN
CLASS="APPLICATION"
>samhain</SPAN
> has been compiled with
<B
CLASS="COMMAND"
>./configure --enable-suid ...</B
></P
><PRE
CLASS="PROGRAMLISTING"
> 
# 'check_samhain' command definition
define command{
command_name check_samhain
command_line $USER1$/check_samhain -t 100
}</PRE
><P
>Checking the filesystem may take some time, so you may want to 
increase the nagios plugin timeout by changing the following line 
in <TT
CLASS="FILENAME"
>nagios.cfg</TT
> from 60 to 600:</P
><PRE
CLASS="PROGRAMLISTING"
> 
service_check_timeout=600</PRE
><P
>Then add the service to the appropriate section in the 
nagios <TT

>service.cfg</TT
