<p class="SectionTitle"><a name="FAQ1"></a>The scripts outputs "Can't
locate Net/SNMP.pm in @INC....."</p>
<p class="SectionBody">You don't have Net::SNMP installed, see below</p>
<p class="SectionTitle"><a name="FAQ2"></a>How do I install Net::SNMP
perl module ?</p>
<p class="SectionBody">There are 2 ways of doing this </p>
<p class="SectionBody"><b>1) By CPAN (best)</b></p>
<p class="SectionBody">on command line, as root : <br>
<br>
[your_host]# <b>perl -MCPAN -e shell</b><br>
cpan shell -- CPAN exploration and modules installation (v1.76)<br>
ReadLine support enabled<br>
cpan> <b>install Net::SNMP</b><br>
</p>
<p class="SectionBody">If it's the first time you run CPAN, it will
probably ask you some (simple) questions.</p>
<p class="SectionBody">CPAN will also ask you to satisfy some dependencies
(Crypt::DES, Digest::MD5, etc..).</p>
<p class="SectionBody"><b>2) "By hand"</b><br>
</p>
<p class="SectionBody">Get the folowings modules (tar.gz format) on
<a href="http://www.cpan.org">www.cpan.org</a></p>
<p class="SectionBody">- Crypt::DES<br>
- Digest::MD5<br>
- Digest::SHA1<br>
- Digest::HMAC<br>
- Net::SNMP<br>
<br>
for each one (you must install Net::SNMP at the end) : <br>
<b>tar zxf <module>.tar.gz<br>
cd <module><br>
perl Makefile.pl<br>
make test<br>
make install</b></p>
<p class="SectionTitle"><a name="FAQ3"></a>What are the supported
platforms to run the scripts on ?</p>
<p class="SectionBody">Most Linux, maybe some unixes and maybe Cygwin.<br>
Actually anything you can run perl on.<br>
If you can install the latest Net::SNMP module, then the perl version
should be OK.</p>
<p class="SectionTitle"><a name="FAQ4"></a>How do I get help on the
options ?</p>
<p class="SectionBody">Just run <b><script> -h </b>on the command
line.<br>
<br>
</p>
<p class="SectionTitle"><a name="FAQ5"></a>Return code of X is out
of bounds</p>
<p class="SectionBody">Have a look at : <a href="http://www.nagios.org/faqs/viewfaq.php?faq_id=17">http://www.nagios.org/faqs/viewfaq.php?faq_id=17</a></p>
<p class="SectionBody">In case of return code 127, try putting perl
in the command line definition : </p>
<p class="SectionBody"> define command{<br>
command_name check_disk<br>
command_line <b>/usr/bin/perl</b> $USER1$/check_snmp_storage.pl
-C $ARG1$ [........]<br>
}<br>
</p>
<p class="SectionTitle"><a name="FAQ6"></a>Are these plugins compatible
with Nagios 2.0 ?</p>
<p class="SectionBody">Yes.</p>
<p class="SectionTitle"><a name="FAQ7"></a>ERROR: XXXXXX : Expected OBJECT IDENTIFIER in dotted notation.
</p>
<p class="SectionBody">Upgrade your Net::SNMP module version (5 is good, 4 maybe OK, 3 gives this error) <br>
This happens with Debian Woody (Net::SNMP version 3.6).<br>
I have special patches if you can't upgrade : contact me.</p>
<p class="SectionTitle"><a name="FAQ8"></a>"No Output" using
Nagios 2</p>
<p class="SectionBody">It's a "bug" of embeded perl. It
has been corrected in latest Nagios releases.</p>
<p class="SectionBody">You can :<br>
</p>
<p class="SectionBody">- Add a patch if your nagios release is old.
Here is a patch made by Gavin Carr for the p1.pl file to correct
this (it should be in nagios CVS shortly). <a href="http://nagios.manubulon.com/p1-print.pl.patch">http://nagios.manubulon.com/p1-print.pl.patch</a>
</p>
<p class="SectionBody">- Upgrade Nagios.<br>
<br>
- add "/usr/bin/perl" before the script command so Nagios
won't use embeded perl. </p>
<p class="SectionTitle"><a name="FAQ9"></a>Getting : "ERROR:
Size table :Message size exceeded buffer maxMsgSize"</p>
<p class="SectionBody">Your snmp table is too big.</p>
<p class="SectionBody">Some of my scripts (check_snmp_storage and
check_snmp_process) now have an option (-o) to set this directly
on command line (thx to Makina Corpus for the patch).</p>
<p class="SectionBody">In other scripts, try adding :</p>
<p class="SectionBody"> $session->max_msg_size(5000);<br>
</p>
<p class="SectionBody">After the session has been initialized. </p>
<p class="SectionTitle"><br>
<a name="FAQM3"></a>Are these scripts secure ?</p>
<p class="SectionBody">Not at all ! You must secure the Nagios server.<br>
Nobody else than the nagios user should be allowed to even think
about running these scripts.<br>
</p>
<p class="SectionTitle"><a name="FAQM1"></a>How can I get help ? Is
there a mailling list ? a forum ?</p>
<p class="SectionBody">Go to the sourceforge project page for all this : <a href=http://sourceforge.net/projects/nagios-snmp/>Nagios-snmp</a>
<p class="SectionBody"><a name="FAQM2"></a><span class="SectionTitle">Can
I donate to help this project ?</span></p>
<p class="SectionBody">Of course you can, I just haven't got any idea
of how, so just send a postcard to my son (Jolan) with a nice drawing (or buy a cookie to your son/daughter/nephew/grand-ma...).<br>
You can get my postal address on my resume (<a href="http://www.manubulon.com/cvpproy.htm">www.manubulon.com/cvpproy.htm</a>).<br>
He will answer you when he knows how to write (in several years).</p>
