Change snmp.conf to allow snmp requests from 127.0.0.1

It seems the first query (ifInOctets.1) is working, but the second
(ifOutOctets.1) is not.

What does the following command produce

snmpget -v1 -c public localhost 1.3.6.1.2.1.2.2.1.16.1

Also, you don't want to be using .1 most likely, as its usually
associated with the loopback interface, as shown below. The number for
the interface you want will be different on your system.

$ snmptable -v1 -c public belgarath ifTable | cut -b-33
SNMP table: IF-MIB::ifTable

ifIndex ifDescr ifType
1 lo softwareLoopback
2 eth0 ethernetCsmacd
3 eth1 ethernetCsmacd
4 eth2 ethernetCsmacd
5 sit0 tunnel
6 ppp0 ppp
7 sit1 tunnel
8 tun6to4 tunnel

I think you are having the same problem that I am trying to chase
down.

I have two routers side by side running HSRP... I am summing the
bandwidth from interfaces on each router using MRTG with two targets
being added. No biggy. Unless you shut one router off!!

Once you shutdown one of the interfaces being summed. The sum stops
displaying proper data. It is as if there is no initialization taking
place.

Target[greg_sum]: 21:nope@192.168.10.44 + 2:nope192.168.10.175

Line 487 in SNMP_util.pm dies in MRTG 2.0.12. The only thing I can
figure to do is rewrite SNMP_util.pm such that it doesn't die when an
evaluated expression does not render defined data for each component
of the expression. The only way to do this would be to somehow
initialize the expression.


WARNING: skipping because at least the query for ifInOctets.2 on
192.168.10.175 did not succeed
WARNING: no data for ifInOctets&ifOutOctets:nope@192.168.10.175.

In reference to the loopback respone. In the ISP world you always
want to query the loopback address because it represents the router-id
for the most part. It is the thing that will always be reachable if
the router is reachable at all.

Greg
