Hi Mostafa,
Thank you for response.
I have given information that SNMPv3 inform should be sent out until it
will get response from NMS. I didnot not get much information about SNMPv3
Informs in RFC3414. Could you please share RFC that has information about
SNMPv3 inform.
Thanks,

Hi All,
As per my knowledge, Whenever trap-destination is unreachable snmpv3
informs retries upto default retry i.e 5 (if not defined) and in default
timeout.
Kindly let me know if this is correct.
Eg:

No that is not possible. It actually doesn't have to do with Net-SNMP,

Hi,
I'm working on snmpv3. In the RFC and internet I haven't seen any
documentation regarding how the encryption and hashing algorithms exchanged
between the entities. I wonder will there be any cipher negotiation happens
in SNMPv3 or both parties should agree upon a specific set of
Hi,
I am developing an embedded product where we are using Net-SNMP as monitoring
interface.
Currently using SNMPv3/USM but due to the MiTM security issue[1] outline by Wes
Hardaker, we want to move to SNMPv3/DTLS.
So I am exploring the possibility of using DTLS with Pre-Shared Keys (PSK
tate->waiting = 0;
snmp_log(LOG_WARNING,"count -1");
}
}
*response = state->pdu;
ss->callback = cbsav;
ss->callback_magic = cbmagsav;
return state->status;
}

I have installed net-snmp 5.6.2.1 and sent out snmp get request using
snmpget command. This is a SNMPv3 request over TLS that i'm sending.
snmpget request sends out two get request
1) Read operation for snmpEngineID.0
2) Actual get request querying for a MIB variable say sysContact.0

Hi,
I've been bothered with my Perl scripts segfaulting due to use of freed data;
it seems that under certain circumstances (e.g., when retries are needed),
you can get callbacks for SNMP reports multiple times, and there is no way
that I can see for the script to know which one is the last one or
callback so it’s not
easy to connect the dots.
Thanks for responding on this.

Net snmp documentation is pretty bad. Don't expect an answer. Better off
writing separate apps to handle the snmp work and split them up as well if you
really need multiple threads.

Net-SNMP FAQ says that "... SNMPv3 support was never checked for
multi-threading correctness. It is most likely that it is not
thread-safe at this time". Is it still true? The page was last edited on
