Re: UPDATE: Starting snmpd deliver 128 duplicate notifications to each trap2sink destinations

Using the same configuration suggested by Bill in the /etc/snmpd.conf, i.e.:
agentaddress udp:161,tcp:161
trapsess -v 2c -c sekrit udp:172.25.24.236:162
….I still having 64 duplicates on management station of this trap:
.iso.org.dod.internet.mgmt.mib-2.system.sysUpTime.0:  TimeTicks:  0 hours, 0 minutes, 0 seconds.: .iso.org.dod.internet.snmpV2.snmpModules.1.1.4.1.0:  Object ID:  .1.3.6.1.6.3.1.1.5.1: .iso.org.dod.internet.snmpV2.snmpModules.1.1.4.3.0:  Object ID:  .1.3.6.1.4.1.8072.3.2.10:

You don't say much about *exactly* what's in your snmpd.conf, but I tried
this:

agentaddress udp:161,tcp:161,udp6:161,tcp6:161
trapsess -v 2c -c sekrit udp:172.25.24.236:162

and I got exactly one packet:

12:26:15.577079 44:4c:a8:64:2b:df > be:7e:8c:45:ca:7e, ethertype IPv4
(0x0800), length 138: (tos 0x0, ttl 59, id 43952, offset 0, flags [DF],
proto UDP (17), length 124)
    172.30.188.156.57296 > 172.25.24.236.snmptrap:  { SNMPv2c C="sekrit" {
V2Trap(81) R=456329610  .1.3.6.1.2.1.1.3.0=1869016
.1.3.6.1.6.3.1.1.4.1.0=.1.3.6.1.4.1.8072.4.0.3
.1.3.6.1.6.3.1.1.4.3.0=.1.3.6.1.4.1.8072.4 } }

This is using net-snmp 5.8.
