Hi,
As I said in my last post, i am able to get all things done correctly if I
have single session and I use single session APIs.
But for several SNMPv3 users, I need to create multiple sessions.
In this case, I am using function:
transport = netsnmp_tdomain_transport(port, 1, udp)
Here, port

But, it returns valid pointer only on 1st call. After that, it always

Actually, if I am using the same handle everytime, then while calling
connect, fd_set contains the same ID for 4 sessions and count=4 (e.g. for
4 sessions).
And the result is that: snmp_read doesn't return (till we receive 4

Hi Dave,
Thanks for your response so far.
Actually, the final problem is in comparing the engine-id received in UDP
packet with that in user database.
If I send engine-id using command:
snmptrap -e *0x0102030405* -v 3 -u administrator -a MD5 -A mypassword -l
authNoPriv -d localhost 42

I got the point due to which problem is occurring.
Please find the code below:

The APIs are reading all values correctly till the point Security parameters
need to be read. Even, Security name is read correctly.
The command used is:

authNoPriv -d localhost 42 coldStart.0

The secEngineID value is some garbage value and secEngineIDLen is 5.

Hi,
I am developing a SNMP trap daemon (snmptd) using net-snmp library. I have
successfully developed the software for SNMP v1 and v2, but I am unable to
code it correctly for v3 traps.
snmptd is able to receive the traps from agent, but the callback is not
called after receiving the trap.

This already handled SNMPv3

I suggest you start with something simpler.
Have you tried with noAuthNoPriv?
Does that work or not?
Dave
No even noAuthNoPriv doesn't work..V1 and V2 works perfectly fine

OK - it looks as if there's something fundamentally wrong.
How are you creating the SNMPv3 users within the trap receiver?
Dave
Following is the code I am using to create user (trying with 1 user for
now):
sprintf(buf,-e %s %s,0x0102030405,administrator);
strcat(buf, MD5 );
strcat(buf,mypassword);
usm_parse_create_usmUser(NULL,buf);
and then sending the trap using snmptrap with following
Hi Dave,
I am glad to say that I have atleast some clue about the issue (this might
help us to find root cause easily now).
I am debugging my software using the net-snmp library code. I am able to
find that there is a parse error in SNMPv3 trap i.e. function snmpv3_parse
returns -43 as failure

Hi,
Yes I got it. From this error, I think I am not able to create the user
properly. Is it true? If yes, please tell me some way to create an SNMPv3
user.
Using the documentation, I am using the command:
