SNMPTT No access configuration - dropping trap

Question

I have a host server that has its own MIB file, but I need to be able to catch the MIB traps on Nagios 4.1 core. I'm using the SNMPTT plugin installed on a RedHat 6.5, but I'm not able to get my traps inside my SNMPTT.

I generate snmp events ./simulate_events_tf.sh (on my monitored host)

/etc/snmp/snmptrapd.conf:

# Example configuration file for snmptrapd'

# No traps are handled by default, you must edit this file!

disableAuthorization yes

#authcommunity log,execute,net public       

#traphandle default /usr/sbin/snmptt

traphandle default /usr/sbin/snmptthandler

# traphandle SNMPv2-MIB::coldStart /usr/bin/bin/my_great_script col

I tried commenting #disableAthorization yes and uncommeting authcommunity log,execute,net public on the file /etc/snmp/snmptrap.conf — MethodistMX, Sep 18 '15 at 21:49

Do you get an error when running

snmptrapd -f -Lo

Your error is probably something like this

Warning: no access control information configured.
    (Config search path: /usr/local/etc/snmp:/usr/local/share/snmp:/usr/local/lib/snmp:/root/.snmp) This receiver will *NOT* accept any incoming notifications.

It might be that the conf file you edited is not on that path. In that case copy /etc/snmp/snmptrapd.conf to a path from the error message.

It worked for me a few minutes ago.
