I am writing a Trap Receiver and was not able to receive an INFORM. I figured out that the command code contained in the PDU was not the 166 as it should be but I received 160.
I thought that maybe I did something wrong, but when i used another program (mibbrowser) to send an inform trap, i got the correct code of 166.
Maybe I am getting something wrong but I really think that this is a bug in the package shipped with Ubuntu and I think that should really not be the case.
#define SNMP_MSG_GET (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x0) /* a0=160 */
#define SNMP_MSG_GETNEXT (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x1) /* a1=161 */
#define SNMP_MSG_RESPONSE (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x2) /* a2=162 */
#define SNMP_MSG_SET (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x3) /* a3=163 */
#define SNMP_MSG_GETBULK (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x5) /* a5=165 */
#define SNMP_MSG_INFORM (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x6) /* a6=166 */
#define SNMP_MSG_TRAP2 (ASN_CONTEXT | ASN_CONSTRUCTOR | 0x7) /* a7=167 */

I thought that maybe I did something wrong, but when i used another program (mibbrowser) to send an inform trap, i got the correct code of 166.
I then figured out, that this behaviour only happens when version 3 is used.
