Hi,
I'm new to Linux. Following the SNMP MFD example (
http://www.net-snmp.org/wiki/index.php/MFD:ifTable:Testing), I'm writing an
SNMP extension agent using the MIB for Dummies (
http://www.net-snmp.org/wiki/index.php/MIB_for_Dummies) config file
(mib2c.mfd.conf).
I successfully created my executable, adeSensorsTable, using my own
adeSensorsTable.MIB (mib2c util auto-generated the C source code from
adeSensorsTable.MIB which I compiled into an executable). Following the
MFD:ifTable:Testing example, I then ran my executable:
./adeSensorsTable -f -L -DadeSensorsTable -M localhost:1161
It returns:
No log handling enabled - turning on stderr logging
registered debug token adeSensorsTable, 1
adeSensorsTable:init_adeSensorsTable: Registering adeSensorsTable as a
mibs-for-dummies table.
On a separate terminal I ran:
snmpwalk -v 1 -c public localhost:1161
Timeout: No Response from localhost:1161
adeSensorsTable terminal would return:
Connection from UDP: [127.0.0.1]:52684->[127.0.0.1]
Connection from UDP: [127.0.0.1]:52684->[127.0.0.1]
Connection from UDP: [127.0.0.1]:52684->[127.0.0.1]
Connection from UDP: [127.0.0.1]:52684->[127.0.0.1]
Connection from UDP: [127.0.0.1]:52684->[127.0.0.1]
Connection from UDP: [127.0.0.1]:52684->[127.0.0.1]
If I ran "snmpwalk -v 1 -c public localhost" I'd get pages of responses
back. This is just the first few lines of the responses:
SNMPv2-MIB::sysDescr.0 = STRING: Linux ken-Extensa-5620 3.2.0-67-generic
#101-Ubuntu SMP Tue Jul 15 17:45:51 UTC 2014 i686
SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (21084) 0:03:30.84
SNMPv2-MIB::sysContact.0 = STRING: G. S. Marzot <gmar...@marzot.net>
SNMPv2-MIB::sysName.0 = STRING: ken-Extensa-5620
SNMPv2-MIB::sysLocation.0 = STRING: Unknown
SNMPv2-MIB::sysORLastChange.0 = Timeticks: (1) 0:00:00.01
I tried to use snmpget to reach one of my extension agent objects using
snmptranslate to find my object OID:
snmptranslate -On xxxxx-MIB::adeSensorsTable.aDESensorsEntry.vrms
and got:
.1.3.6.1.4.1.43905.1.1.1.1.2
then I ran:
snmpget -v 1 -c public localhost:1161 .1.3.6.1.4.1.43905.1.1.1.1.2
I'd get the same response:
Connection from UDP: [127.0.0.1]:55176->[127.0.0.1]
Connection from UDP: [127.0.0.1]:55176->[127.0.0.1]
Connection from UDP: [127.0.0.1]:55176->[127.0.0.1]
Connection from UDP: [127.0.0.1]:55176->[127.0.0.1]
Connection from UDP: [127.0.0.1]:55176->[127.0.0.1]
from adeSensorsTable executable.
I'm not sure what I'm missing here. I'd appreciate if someone could
provide some pointers to my timeout issue. Thank you in advance!
