In which case, things are working as expected. snmptable will send one GETNEXT request for each row of the table, plus one additional request to discover that it's reached the end. Try working this through by hand - you should see why things work that way.

That description is essentially meaningless. I've no idea what your code looks like, so giving me one line in isolation is no use whatsoever. > 2.

This will allow you to query the kernel once, and keep the information available for the next few seconds - typically sufficient to serve a complete "snmpwalk" or "snmptable".

snmptrapd skips "traphandle" line that are not "default" from the snmptrapd.conf file.
Hi, I'm having a problem making the snmptrapd behave the way I would like it to. I'm trying to catch a specific OID, but can't really do so: this is my snmptrapd.conf: authCommunity log,execute,net public authCommunity log,execute,net private logoption f /var/log/snmp-received.log traphandle .1 /home/daniel/NMS/web/alert_trapper.py traphandle SNMPv2-MIB::snmpTrapOID.0.0.17 /home/daniel/NMS/web/alert_trapper.py traphandle SNMPv2-MIB::snmpTrapEnterprise.0 /home/daniel/NMS/web/alert_trapper.py traphandle SNMPv2-MIB::snmpTrapOID /home/daniel/NMS/web/alert_trapper.py traphandle .1.3.6.1.6.3.1.1.4.1.0.0.17 /home/daniel/NMS/web/alert_trapper.py traphandle .1.3.6.1.6.3.1.1.4.1.0 /home/daniel/NMS/web/alert_trapper.py traphandle SNMPv2-MIB::snmpTrapOID.0 /home/daniel/NMS/web/alert_trapper.py traphandle iso.5.4.2.2.2 /home/daniel/NMS/web/alert_trapper.py traphandle .1.5.4.2.2.2 /home/daniel/NMS/web/alert_trapper.py traphandle .1.3.6.1.6.3.1.1.4 /home/daniel/NMS/web/alert_trapper.py #traphandle default /home/zabbix/zabbix-1.8.2/misc/snmptrap/snmptrap.sh #traphandle default /home/daniel/NMS/web/alert_trapper.py There are lots of "traphandle" lines above, but none of them could catch this one: /usr/bin/snmptrap -v 1 -c public 10.0.0.141 1.5.4.2.2.2 localhost 6 17 '' 1.5.4.2.2.2.1 s "Hello" If I uncomment the last traphandle line (the default one), it will catch it, and call the handler twice for some reason. Somebody knows why? No matter what I tried to do, it wouldn't catch anything besides from the unspecific default handler. Maybe I'm missing something? I can see in the log that it sees the trap: 2010-08-18 16:55:29 localhost [127.0.0.1] (via UDP: [10.0.0.141]:34903->[10.0.0.141]) TRAP, SNMP v1, community public iso.5.4.2.2.2 Enterprise Specific Trap (17) Uptime: 2 days, 0:33:42.88 iso.5.4.2.2.2.1 = STRING: "wazzup?"

snmpd returns truncated sysObjectId
a) last week someone posted a patch on the net-snmp-bugs list to fix a sysObjectId directive truncation problem, b) last nov 30 (2009) someone posted a patch to fix a sysObjectId truncation problem c) in july 2006 someone complained about sysObjectId truncation. I was sadly bit by this bug today on a Windows system running Net-SNMP v5.5 (I had been developing all along on Linux boxes.) Unfortunately, some of my sites run Windows, and can only install pre-built binaries (but I have no Windows build facilities). What should I do? - wait for 5.5.x This will probably never happen ? - wait for 5.6 How long do I have to wait ? - downgrade to 5.4.2.1 My best solution ? Or... how could I get pre-built Windows binaries of up-to-date stuff?
