Use of DTLS (Datagram Transport Layer Security) with SNMP and Management Systems

Question

Does anyone know if the current crop of SNMP based commercial and open source network management systems (eg, HP OpeenView/NNM, OpenNMS) support the use of SNMP over DTLS (http://tools.ietf.org/html/rfc4347)?

Thanks in advance...

Answer 1

With regards to OpenView, OpenNMS, etc.: I'm not sure.

I do know that Net-SNMP does not yet support this, but it is in the works.

This is from the Net-SNMP coders mailing list. I ran into an issue with v3 thread-safeness and received this reply.

Wes Hardaker:

The SNMPv3 support in Net-SNMP isn't, unfortunately, thread-safe. We think/hope that the replacement DTLS/TLS support coming out in a future release will make it thread-safe when used over DTLS though.

Hope this is somewhat helpful.
