[mrtg] snpo error in some targets

[Alvaro Cornejo]

Hi List,

Continuing with MRTG deployment, I want to monitor some info from a
Linux (fedora6) machine. I've successfully set up several targets but
for some of the values I want to monitor I get some errors from MRTG;
however if I do snmpget/snmpwalk from the shell I do get the correct
values.

Below is a log from that.

Regards

Alvaro
