ADDENDUM (again) Ok, you see that I have another "scasnmpd" running too. That's for another package, but I killed those and left /usr/sbin/snmpd running and it had the same error. I restarted /etc/rc.d/init.d/snmpd too and same error. Sorry for all of the separate submissions. - Steve
This behaviour disappears when you change the /etc/snmp/snmpd.conf file I changed the view and access to view all included .1 access notConfigGroup "" any noauth exact all none none
Ahh! That did it. Now snmp and mrtg are both working! Woohoo! Thanks everyone!
Red Hat distributes ucd-snmp with conservative, pessimistic and possibly surprising default configuration, originally suggested by Wes Hardaker, the ucd-snmp maintainer.
