i’m having trouble installing MRTG on a windows 2000 machine. it seems like the AP is not sending it’s SNMP information. i followed the steps in the install docs.
i have a server with three NICs, running three IPs, could this be giving me trouble? also, i have my APs on private IP space, for example 10.0.0.21, so is the proper setting on the AP “Accessing subnet: 10.0.0.1 /8” and the trap address is the IP of the MRTG server? i don’t see how i’m having so much trouble with such a simple process. thanks for help anyone.
Here is my error on the install:
perl cfgmaker public@10.0.0.21 --global “WorkDir: c:'www’mrtg” --output mrtg.cfg
–base: Get Device Info on public@10.0.0.21:

It’s seems to me, you HAVE TO set snmp to V2.
default on mrtg is v1? and i have to change the config to v2? ok, gotcha, did everything else look ok to you? thanks for the quick response!
how exactly do you change MRTG over to version2 SNMP? i don’t see it anywhere in the docs.
Just add
:::::2
to the end of your Target string in mrtg.cfg
I.E.
Target[your_ap]: 2:public@10.0.0.21:::::2
