Parameter for SNMPv3 with SHA256 and AES

[MPell]

Dear Nedi community,

after a system update, a network device only supports SNMPv3 with SHA256 or SHA512 for authentication and DES, AES or AES256 as privacy protocol. (Before I used MD5 and AES). So I have to change the Authentication Protocol. The test-query via snmpget on the Linux console works (in my examlpe for SHA256 and AES). How can I use the tightened security parameters in NeDi? I tried "sha256" for aprot:

Code: [Select]

comm snmpv3user sha256 authpass aes privpass
The error message on discovery is:

Code: [Select]

MSG=SNMP failed with The authProtocol "sha256" is unknown
Does anyone know the right hint?

I use ubuntu LTS22.04 Server and NeDi 2.2C

Thanks Markus

This guy has a solution: https://www.claudiokuenzler.com/blog/1205/how-to-perl-net-snmp-v3-authentication-protocol-support-newer-sha-sha256-sha512

It's worth a try...

Hi Remo,

you made out the point. Using the patched USM.pm works like a charme. Thanks a lot for the hint!

Best regards, Markus
