Enable SNMP on Mac OS X

I am trying to enable SNMP version 3 with a single ready-only user on Mac OS X 10.8.5 so that I can remotely monitor the health of the computer. When I attempt a local snmpwalk, this message is returned: No log handling enabled - using stderr logging snmpwalk: Authentication failure (incorrect password, community or key) Below are the exact steps I executed to get to this point. What am I missing? FYI, the username I am using is rouser with password 12345678 sudo snmpconf -i creates /usr/share/snmp/snmpd.conf with permissions -rw-r--r-- 1 root staff 484 Sep 25 14:44 snmpd.conf and contains: # snmpd.conf # - created by the snmpconf configuration program # # SECTION: Access Control Setup # # This section defines who is allowed to talk to your running # snmp agent. # rouser: a SNMPv3 read-only user # arguments: user [noauth|auth|priv] [restriction_oid] rouser rouser priv create user: sudo net-snmp-config --create-snmpv3-user -ro -a 12345678 -x 12345678 -X AES -A SHA rouser that creates /var/db/net-snmp/snmpd.conf with permissions -rw-r--r-- 1 root wheel 46 Sep 25 14:44 snmpd.conf and contains: createUser rouser SHA "12345678" AES 12345678 that command also updates /usr/share/snmp/snmpd.conf to this (last line added): # snmpd.conf # - created by the snmpconf configuration program # # SECTION: Access Control Setup # # This section defines who is allowed to talk to your running # snmp agent. # rouser: a SNMPv3 read-only user # arguments: user [noauth|auth|priv] [restriction_oid] rouser rouser priv rouser rouser enable SNMP: sudo launchctl load -w /System/Library/LaunchDaemons/org.net-snmp.snmpd.plist that command changed the permissions of /var/db/net-snmp/snmpd.conf to -rw------- 1 root wheel 1420 Sep 25 15:04 snmpd.conf and changed its contents to: # # net-snmp (or ucd-snmp) persistent data file. # ############################################################################ # STOP STOP STOP STOP STOP STOP STOP STOP STOP # # **** DO NOT EDIT THIS FILE **** # # STOP STOP STOP STOP STOP STOP STOP STOP STOP ############################################################################ # # DO NOT STORE CONFIGURATION ENTRIES HERE. # Please save normal configuration tokens for snmpd in SNMPCONFPATH/snmpd.conf. # Only "createUser" tokens should be placed here by snmpd administrators. # (Did I mention: do not edit this file?) # usmUser 1 3 0x80001f888098ad4f304567245400000000 "rouser" "rouser" NULL .1.3.6.1.6.3.10.1.1.3 0x22051a77e41dc526caebc92dc387257482bcd$ setserialno 1673336648 ############################################################## # # snmpNotifyFilterTable persistent data # ############################################################## ############################################################## # # ifXTable persistent data # ifXTable .1 14:0 18:0x $ ifXTable .2 14:0 18:0x $ ifXTable .3 14:0 18:0x $ ifXTable .4 14:0 18:0x $ ifXTable .5 14:0 18:0x $ ifXTable .6 14:0 18:0x $ ifXTable .7 14:0 18:0x $ ifXTable .8 14:0 18:0x $ ############################################################## engineBoots 1 oldEngineID 0x80001f888098ad4f304567245400000000 try querying the system locally: snmpwalk -v 3 -u rouser -l authPriv -a MD5 -A 12345678 -x DES -X 12345678 localhost .1 that returns: No log handling enabled - using stderr logging snmpwalk: Authentication failure (incorrect password, community or key) /var/log/snmpd.log: /etc/snmp/snmpd.conf: line 61: Error: example config COMMUNITY not properly configured /etc/snmp/snmpd.conf: line 62: Error: example config NETWORK not properly configured net-snmp: 2 error(s) in config file(s) NET-SNMP version 5.6 Authentication failed for rouser Authentication failed for rouser disable SNMP in the meantime sudo launchctl unload -w /System/Library/LaunchDaemons/org.net-snmp.snmpd.plist Any thoughts?
