Hi. Yes, I did a similar test to send SIGHUP, and looking at traps with Wireshark, the engineBoots count does stay the same while the engineTime increases as expected. So I guess the simple reconfig is not the problem. The kind of “event” I saw that I thought may have triggered the engineBoots increment was a change to the IF MIB contents, due to a network interface going down then up. There was a debug message in snmpd.log that an interface had changed. I don’t see the connection in code for what would invoke the function that increments the engineBoots count, though. It’s a callback so it’s not easy to connect the dots. Thanks for responding on this.

I’m having trouble with some of the SNMPv3 traps sent by snmpd being rejected, and I think it’s because of the SNMPv3 replay protection mechanism. It looks like when some event causes a reconfigure of snmpd Can you say more about what kind of event? It doesn't happen (at least, in 5.7.2) with HUP - engineBoots before and after a HUP doesn't change for me. notification before HUP: dumph_recv: msgAuthoritativeEngineBoots dumpv_recv: Integer: 1 (0x01) dumph_recv: msgAuthoritativeEngineTime dumpv_recv: Integer: 785 (0x311) notification after HUP: dumph_recv: msgAuthoritativeEngineBoots dumpv_recv: Integer: 1 (0x01) dumph_recv: msgAuthoritativeEngineTime dumpv_recv: Integer: 843 (0x34B) Bill ------------------------------------------------------------------------------ Comprehensive Server Monitoring with Site24x7.
