I modify snmptrapd.conf to:
createUser -e 0x80001f88806a19937bd3c75547
test_MD5_AES MD5 12345678 AES 87654321
authuser log,execute test_MD5_AES
logOption s u
traphandle "default" /home/powah/snmp/traps test
...
Why I still get no match on engineID?
Isn't test_MD5_AES has the correct engineID?
What is the proper way to get the engineID of the
snmpd? Is it in the file /var/net-snmp/snmpd.conf?
# snmptrapd -f -Le -Dusm -d -c
