[Nut-upsuser] [EXTERNAL] SNMP shutdown timing out

[David Zomaya]

The encryption of SNMPv3 will might make it little harder to debug with tcpdump if you have to drill into packet contents. Switching to v1/2c for troubleshooting would make it plaintext, but then not exactly apples to apples to now.


Maybe someone will have a more elegant suggestion.




Thank you,

I tried setting them all with -x thing= arguments as well as letting it
pull from ups.conf, same result. It's all SNMPv3 settings.

sudo snmp-ups -DDDD -a nutdev1 -x secLevel=authPriv -x secName=nut -x
authProtocol=MD5 -x privProtocol=DES -x
authPassword=NutScan at Password43LongerWord -x
privPassword=NutScan at Password43LongerWord -k

The output with -DDDD is the same either way.

I guess that really is the next step, isn't it? Darn. I was hoping to
avoid that. Can't do it until Monday, I'm out of time for this project
this week. Thanks for the suggestion.
