Hello,
I am trying to get SNMPv3 traps received in snmptrapd.exe on Net-SNMP
5.4.1.2. I am using
snmptrap to send the trap.
The following is my snmptrapd.conf:
authCommunity log public
doNotLogTraps false
doNotFork yes
agentxsocket tcp:127.0.0.1:705
createUser -e 0x80001F8804307830313032303330343035 david MD5 mypassword
createUser -e 0x80001F8804307830313032303330343035 taylor MD5 mypassword
createUser myuser MD5 mypassword
createUser -e 0x0102030405 bubba MD5 mypassword DES myotherpassword
The snmptrapd command line is: snmptrapd.exe -c snmptrapd.conf -d -L o -L f
output.txt -D "usm"
Which prints out the following:
registered debug token usm, 1
usmUser: created a new user david at 80 00 1F 88 04 30 78 30 31 30 32 30 33
30 34 30
35
usmUser: created a new user taylor at 80 00 1F 88 04 30 78 30 31 30 32 30 33
30 34 30

usmUser: created a new user myuser at 80 00 1F 88 80 1D 75 00 00 31 ED AC 4C
usmUser: created a new user bubba at 01 02 03 04 05
NET-SNMP version 5.4.2.1
I send the snmptrap for version 2c:
snmptrap -c public -v 2c 127.0.0.1 42 1.3.6.1.4.1.8888.88.1.9
The snmptrapd output to this snmptrap is:
Received 68 bytes from UDP: [0.0.0.0]->[127.0.0.1]:3971
0000: 30 42 02 01 01 04 06 70 75 62 6C 69 63 A7 35 02 0B.....public§5.

0:00:00.42 SNMPv2-MIB::snmpTrapOID.0 = OID:
SNMPv2-SMI::enterprises.8888.88.1.9
This is good.
Now, I send a snmptrap for version 3:
snmptrap -e 0x80001F8804307830313032303330343035 -v 3 -u david -a MD5 -A
mypassword -l authNoPriv 127.0.0.1 42 1.3.6.1.4.1.8888.88.1.9
The snmptrapd output to this snmptrap is:

usm: USM processing begun...
usm: match on user david
usm: Verification succeeded.
usm: USM processing completed.
This is not being successful. I believe that is failing with something to do
with the view access control, but
am not sure.
Does anyone see anything that I am doing wrong?
Thanks,
David
