I have been unable to get mrtg working with Squid on my debian box. I have tried this on two different boxes with the same results.

While snmpget does work I am trying to use a script located at http://www.psychofx.com/chris/unix/mrtg/mrtg-squid.cfg for the mrtg config

Example output:
http://www.psychofx.com/chris/unix/mrtg/squidsample/


Here is an snmpget that does work successfully for squid.
snmpget -v 1 -c public localhost:3401 .1.3.6.1.4.1.3495.1.1.1
SNMPv2-SMI::enterprises.3495.1.1.1 = INTEGER: 92

The problem is that mrtg will not successfully run against squid.

 mrtg /var/www/mrtg/mrtg-squid.cfg
SNMP Error:

By the way I can run mrtf cfgs against this server although for network interface input and output sucsessfully.



The mrtg-squid.cfg I am using is located here
http://www.psychofx.com/chris/unix/mrtg/mrtg-squid.cfg I am making the
changes requested in the commented section at the beggining for hostname
etc.


System Specifics:
Debian
kernel 2.4.21
mrtg 2.9.29-1
squid 2.5.4-2
snmpd 5.0.9-3
