RE: mrtg config file for squid-1.2.beta20?

Hi,

I had the same problem and the solution is a as follows...mrtg asks for
sysContact, sysDescr, and sysName, which have the following OIDs

   'sysDescr' => '1.3.6.1.2.1.1.1.0',
   'sysContact' => '1.3.6.1.2.1.1.4.0',
   'sysName' => '1.3.6.1.2.1.1.5.0'

The SNMP daemon from squid does not have these OIDs in their standard
places...a quick fix to get mrtg to poll the snmp daemon from squid is
to copy mrtg to mrtg-squid (if you are monitoring other machines or
routers) and change the OID numbers in mrtg-squid to :

   'sysDescr' => '1.3.6.1.3.25.17.2.2',
   'sysContact' => '1.3.6.1.3.25.17.2.1',
   'sysName' => '1.3.6.1.3.25.17.2.3'

I don't know if the NLANR developers will include the correct OIDs for
the three mentioned instances in their squid source, but it would be
nice.

If you have any more problems let me know...
