I meant to send this to the list but evidently only sent it to David. Since sending it I've done a second test which shows what a successful snmpset looks like.
First attachment, from the forwarded email, is nutout.txt. Second attachment is snmpout.txt. nomad -------- Forwarded Message -------- Subject: Re: [Nut-upsuser] [EXTERNAL] SNMP shutdown timing out Date: Mon, 4 May 2020 09:28:57 -0700 From: Lee Damon <[email protected]> To: David Zomaya <[email protected]> On 4/29/20 4:11 PM, David Zomaya wrote: > The encryption of SNMPv3 will might make it little harder to debug with > tcpdump if you have to drill into packet contents.

The first command, nut-scanner, showed no traffic at all, probably not surprising given the error: : || lvd@chscc-pc-052 ~ [1121] ; please tcpdump host apcups and port snmp tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eno1, link-type EN10MB (Ethernet), capture size 262144 bytes ^C 0 packets captured 4 packets received by filter 0 packets dropped by kernel But the second command, snmp-ups, showed unencrypted traffic.
