SNMP multiple request
Hi, I'm quite new on the SNMP protocol and I'm trying to figure out if the last version of SNMP (v3) supports IP multicasting. I've that some kind of frameworks have been proposed as a possible solution but I don't really know if it is already standardized. What I would like to know if it possible to make a unique request (using multicast IPs) from the SNMP manager to several agents in order to get information from them. Can anyone help me? Thanks!

RE: snmptrap source ip
Thank you for you detailed response. I meant traps and not informs. In any case, I rechecked it without a port (giving clientaddr only an IP and not of the form ip:port like I tried until now), and it worked both on 5.4.1 and 5.4.2. So, the problem was that I assumed that the regular structure of ip:port is permitted.

Aside from the fact you're using informs, sound like you? OK, either way, it might be worth reading my original bug report with submitted patch to 5.4.1: http://sourceforge.net/mailarchive/message.php?msg_id=E1KL19H-0003hG-Ja% 40b55xhf1.ch3.sourceforge.com There is some history here. A guy named Jan Safranek from Red Hat got me constructively motivated to actually submit this patch, but it was after he'd submitted his own, which as I recall was almost identical (certainly was functionally) to solve the same problem (my snmpd.conf param is agenttrapaddr, Jan's was something else. The discussion in this report discussed why I don't think clientaddr affects what you want to affect. Now, both Jan and I submitted our patches (Jan's came in much earlier because he's more on top of it it sounds like :), and net-snmp bug authorities were piecing out which or what kind of hybrid to use. I don't know if that was resolved for an official patch release or not. If so, use that. Either way, we've been running with this patch successfully for over a year now. Note that this *only* affects agent-initiated traps (from monitor directives in snmpd.conf). Also, I didn't test this with informs yet, but as I recall the code flow, both should be positively affected. I'll try to follow the digest better than usual if you have any followup questions here...hope this helps!

I have tried using the -Y clientaddr=ip:port flag but with no success. I also tried setting the clientaddr parameter in the snmp.conf file. The outcome is always the same - the outgoing port is the same (I have only one IP on my testing machine so I assume that if I could preset the port, the ip will be also set. Please mind I am working with 5.4.1 netsnmp version. Does snmptrap.exe (windows XP) suppose to be influenced from this parameter or is it only for snmpd and snmptrapd? If only for snmpd and snmptrapd, how can I set the source ip of outgoing traps if I am using the snmptrap.exe to send them?

Problem with using pthread library
I ran across a problem trying to add my MIBS where net-snmp would hang. I am cross compiling net-snmp to run on a custom embedded linux application. I perform a configure where I add my mib handler files but I also add --with_ldflag=$LDFLAGS, where LDFLAGS=-lpthread. This took me lots of debugging with DEBUGMSGTL statements and I'm using net-snmp-5.4.1..tar.gz for reference. I found that the configure recognizes the fact that I want it linked with -lpthread and proceeds to add to include/net-snmp/net-snmp-config.h the following... #define NET_REENTRANT 1 and #define HAVE_PTHREAD_H 1 Well, this causes a problem where net-snmp is trying to acquire a resource lock using pthread mutexes when it has already acquired a resource lock. So the second attempt to acquire the lock hangs net-snmp. This has nothing to do with the code I added. If you just try add the link to pthread in the configure the problem occurs. The freeze occurs the first time I send an SNMP ping to my embedded system. I'm curious as to if anyone has heard of this problem? I don't need net-snmp to be reentrant. I just have a small bit of code that runs a thread to communicate with another app that sends/recvs the parameters. I could redesign it to not use threads but the code has already been used a tested so I would rather keep it as is. My solution was to edit net-snmp-config.h after running configure and undoing those defines.

Unknown engine ID
Greetings snmp users. I have configured my snmpd.conf file to use snmpv3, and I ran tests using snmp commands to verify that the snmpget and snmpwalk commands retrieve the requested data from the appropriate MIBs. However, I am encountering a situation where the engine ID seems to be getting dropped or lost after a short period of time (2 to 5 minutes). Since it is not always the same time period, it would not appear to be a coded timeout value. I did not specify an engine ID in the snmpd.conf file because I read that that is not the recommended procedure. So snmp should be generating the engine ID with its algorithm. Please see the snmpget commands below. The timeticks display the number of seconds following the startup of the snmpd daemon. Once the Unknown engine ID msg is returned, the only way to get snmp to process commands again is to restart the snmpd daemon. --- /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (4555) 0:00:45.55 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (8348) 0:01:23.48 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (19107) 0:03:11.07 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (21359) 0:03:33.59 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (22596) 0:03:45.96 /etc snmpget hostname sysUpTime.0 DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (24334) 0:04:03.34 /etc snmpget hostname sysUpTime.0 snmpget: Unknown engine ID (Sub-id not found: (top) - sysUpTime) -- Does anyone have ideas about what is causing the engine ID to get lost?
