SNMP++ Release 3.5.0

SNMP++ 3.5.0 has been released on 2022-10-12T22:00:00Z with an improved message ID handling.


  • Fixed: When using an IPv6 socket to send a SNMPv3 request to an IPv4 target, the engine id could not be discovered.
  • Fixed: Compile error with libressl >= 3.5.0 (Fabrice Fontaine)
  • Improved: Set message_id in Pdu after sending a request to be able to detect old responses: Fixed scenario: Send request, send retry, response to first request is received and processed to unknown pdu handler because of unknown message id. Matching to retry request is done because of known request id.
  • Improved (security): Avoid timing attacks on authentication verification.
