Hi,
I have scanned the mailing archive and read all the manpages regarding
net-snmp without any success on finding any information regarding how to
configure informs for snmpv3.
I would like to create a inform for snmpv3 on the following events linkup,
linkdown, coldstart and warmstart. From the manpages I have managed to
configure the following
###############################################################################
#
# AGENT BEHAVIOUR
#
# Listen for connections from the local system only
agentAddress udp:127.0.0.1:161
###########################################################################
# SECTION: Access Control Setup
#
# This section defines who is allowed to talk to your running
# snmp agent.
# rwuser: a SNMPv3 read-write user
# arguments: user [noauth|auth|priv] [restriction_oid]
rwuser my_userrw
# rouser: a SNMPv3 read-only user
# arguments: user [noauth|auth|priv] [restriction_oid]
rouser my_userro
# rouser: a SNMPv3 read-only user
# arguments: user [noauth|auth|priv] [restriction_oid]
rouser my_mon_user
###############################################################################
#
# ACTIVE MONITORING
#
#
# Event MIB - automatically generate alerts
#
iquerySecName my_mon_user
agentSecName my_mon_user
# generate traps on linkUp/Down
linkUpDownNotifications yes
###############################################################################
I have created all three users my_userrw, my_userro and my_mon_user and all
these users can run snmpwalk or snmpget so I
guess that I have managed to set them up correctly.
When it comes to my snmptrapd I have the following configuration file
snmptrapd.conf
createUser my_mon_user MD5 pass1 DES pass2
snmpTrapdAddr udp:127.0.0.1:162
authuser log my_mon_user
I have verified snmptrapd by running the following command
./snmpinform -v 3 -u my_mon_user -a MD5 -A pass1 -x DES -X pass2 -l
authPriv localhost 42 linkDown.0
which will result in the following output from the snmptrapd
2013-02-13 10:50:29 localhost [UDP: [127.0.0.1]:39612->[127.0.0.1]:162]:
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (42) 0:00:00.42
SNMPv2-MIB::snmpTrapOID.0
= OID: IF-MIB::linkDown.0
But I never get any traps from the snmpd. I try to trigger the linkDown by
running sudo ifconfig eth0 down but without any success.
What is it that I am missing?
