Hi Elad: I hope I'm not confusing matters for you, but it sounds like you're encountering the same situation we encountered a year or so ago, where we needed to have V1 traps sent with a specific chosen interface addr of the options available on a multihomed system--reason being that only one of the addresses on the agent would properly reverse-DNS map when looked up by our management station client that was running its own trap daemon and receiving the trap.
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?

See the thread starting here: http://thread.gmane.org/gmane.network.net-snmp.user/25707/focus=25707 I haven't tried it, but I think if you add '--clientaddr=<source_ip>' to your snmptrap command line it will get you the result you want. -- Glenn McAllister <[EMAIL PROTECTED]> +1 416 348 1594 SOMA Networks, Inc. http://www.somanetworks.com/ +1 416 977 1414 ------------------------------ Message: 4 Date: Tue, 11 Nov 2008 14:16:15 -0600 From: "Allen, Bill" <[EMAIL PROTECTED]> Subject: new to net-snmp, installing on HP-UX To: <net-snmp-users@lists.sourceforge.net> Message-ID: <[EMAIL PROTECTED]> Content-Type: text/plain; charset="us-ascii" I am new to net-snmp. I have an HP-UX 11.23 system that I am trying to monitor with our local monitoring software - SolarWinds. They say I need to install net-snmp on this HP-UX system for this purpose as the default snmp is not sufficient. So, I have downloaded the latest ixNet-SNMP for HP-UX 11.23 from the HP-UX iexpress software set. I did a swinstall on the depot and it appears that net-snmp installed without any errors. However, it appears that the system is still configured to load the default HP-UX snmpd & snmpdm as they are not linking out to the net-snmp installed versions. So, what do I need to do next? Do I need create snmpd & snmpdm links out to net-snmp versions or what? What is SOP for HP-UX and this product. I have not read anything about modifying the rc .d scripts, so I assume that is not the way to go. I did read the README.hp file, but that sounded like what would need to be done if I wanted to compile from source. I should not need to do that since I installed from the HP depot, right? Any help would be appreciated. :-) Thanks, Bill /usr/sbin # ll *nmp* -r-xr--r-- 1 bin bin 8195 Apr 6 2006 snmpd -r-xr--r-- 1 bin bin 1326416 Mar 14 2007 snmpdm lrwxr-xr-x 1 root sys 37 Nov 11 10:19 snmptrapd -> /opt/iexpress/net-snmp/sbin/snmptrapd /usr/sbin # whereis snmpd* snmpd: /usr/sbin/snmpd /usr/share/man/man1m.Z/snmpd.1m /opt/OV/man/man1m.Z/snmpd.1m snmpdm: /usr/sbin/snmpdm /usr/share/man/man1m.Z/snmpdm.1m /usr/bin # ll *nmp* lrwxr-xr-x 1 root sys 42 Nov 11 10:19 net-snmp-config -> /opt/iexpress/net-snmp/bin/net-snmp-config lrwxr-xr-x 1 root sys 38 Nov 11 10:19 snmpbulkget -> /opt/iexpress/net-snmp/bin/snmpbulkget lrwxr-xr-x 1 root sys 39 Nov 11 10:19 snmpbulkwalk -> /opt/iexpress/net-snmp/bin/snmpbulkwalk lrwxr-xr-x 1 root sys 36 Nov 11 10:19 snmpcheck -> /opt/iexpress/net-snmp/bin/snmpcheck lrwxr-xr-x 1 root sys 35 Nov 11 10:19 snmpconf -> /opt/iexpress/net-snmp/bin/snmpconf lrwxr-xr-x 1 root sys 36 Nov 11 10:19 snmpdelta -> /opt/iexpress/net-snmp/bin/snmpdelta lrwxr-xr-x 1 root sys 33 Nov 11 10:19 snmpdf -> /opt/iexpress/net-snmp/bin/snmpdf lrwxr-xr-x 1 root sys 34 Nov 11 10:19 snmpget -> /opt/iexpress/net-snmp/bin/snmpget lrwxr-xr-x 1 root sys 38 Nov 11 10:19 snmpgetnext -> /opt/iexpress/net-snmp/bin/snmpgetnext lrwxr-xr-x 1 root sys 37 Nov 11 10:19 snmpinform -> /opt/iexpress/net-snmp/bin/snmpinform lrwxr-xr-x 1 root sys 38 Nov 11 10:19 snmpnetstat -> /opt/iexpress/net-snmp/bin/snmpnetstat lrwxr-xr-x 1 root sys 34 Nov 11 10:19 snmpset -> /opt/iexpress/net-snmp/bin/snmpset lrwxr-xr-x 1 root sys 37 Nov 11 10:19 snmpstatus -> /opt/iexpress/net-snmp/bin/snmpstatus lrwxr-xr-x 1 root sys 36 Nov 11 10:19 snmptable -> /opt/iexpress/net-snmp/bin/snmptable lrwxr-xr-x 1 root sys 35 Nov 11 10:19 snmptest -> /opt/iexpress/net-snmp/bin/snmptest lrwxr-xr-x 1 root sys 40 Nov 11 10:19 snmptranslate -> /opt/iexpress/net-snmp/bin/snmptranslate lrwxr-xr-x 1 root sys 35 Nov 11 10:19 snmptrap -> /opt/iexpress/net-snmp/bin/snmptrap lrwxr-xr-x 1 root sys 34 Nov 11 10:19 snmpusm -> /opt/iexpress/net-snmp/bin/snmpusm lrwxr-xr-x 1 root sys 35 Nov 11 10:19 snmpvacm -> /opt/iexpress/net-snmp/bin/snmpvacm lrwxr-xr-x 1 root sys 35 Nov 11 10:19 snmpwalk -> /opt/iexpress/net-snmp/bin/snmpwalk -------------- next part -------------- An HTML attachment was scrubbed... ------------------------------ ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ ------------------------------ _______________________________________________ Net-snmp-users mailing list Net-snmp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/net-snmp-users End of Net-snmp-users Digest, Vol 30, Issue 10 ********************************************** ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Net-snmp-users mailing list Net-snmp-users@lists.sourceforge.net Please see the following page to unsubscribe or change other options: https://lists.sourceforge.net/lists/listinfo/net-snmp-users
