The default snmp configuration won't give mrtg the info you want. Look at the
output of snmpwalk on your snmp host.
# sec.name source community
#com2sec paranoid default public
com2sec readonly 10.0.0.1 public
#com2sec readwrite default private
You have something similar in your snmpd.conf. The above lets only 10.0.0.1
access the snmp. This was good enough for me, buy the manual page will tell you
how to let a whole subnet access the snmp data. Though, I'd suggest only
allowing specific hosts to access your snmp.
