Indeed, some trap receivers always accept and print traps regardless of whether or not it has been authenticated. It's the responsibility of the receiver to decide what to do. [some have argued they should always log what they receive, but mark it as whether it was authenticated or not] -- Wes Hardaker Please mail all replies to net-snmp-coders@lists.sourceforge.net ___ Net-snmp-coders mailing list Net-snmp-coders@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/net-snmp-coders

Which trap receiver are you using? snmptrapd, or something else? /Niels Den 25-04-2023 kl. 15:10 skrev Simon Chamlian: I tried the command: snmptrap -v 3 -u Simon -a MD5 -A SimonPass -l authNoPriv 172.27.37.227 "" coldStart.0 (with security name : Simon and authentication password : SimonPass ).

Fwd: snmptrap v3 authentication
Hi, The snmptrap v3 authentication does not seem to be working. I am using Version: 5.9.1 >From my agent, I issue: snmptrap -v 3 -u Simon -a MD5 -A SimonPass -l authNoPriv 172.27.37.227 "" coldStart.0 I do receive the trap on my Trap Receiver even if I didn't specify a Username and Authentication password in the MIB browser (on 172.27.37.227 ) ! I was NOT expecting to receive any traps until I set up the Username and Authentication!?! Any explanation?
