I have been working on trying to get a value with a custom MIB through SNMP following this tutorial. I'm using net-snmp 5.7.3. I have used this MIB along with the corresponding codes with this.
My setup: I have two VM's, both Ubuntu 16, one is snmp-server with IP:192.168.5.20 and the other snmp-agent with IP:192.168.5.21.
I did MIBS=ALL and export MIBS. On the agent, I have successfully compiled my MIB and got the expected output. My code files are in the path /home/snmp-agent/Desktop/proj/net-snmp-5.7.3/agent/mibgroup/. I reconfigure mthe net-snmp like this:
./configure --with-mib-modules="pingCtlTable pingResultsTable pingProbeHistoryTable"
make
make install
Everything worked fine. And when I do snmptranslate on the agent I get:
root@snmpagent:~# snmptranslate -On DISMAN-PING-MIB::pingResultsTable
.1.3.6.1.2.1.80.1.3
root@snmpagent:~# snmptranslate -On DISMAN-PING-MIB::pingCtlTable
.1.3.6.1.2.1.80.1.2
root@snmpagent:~# snmptranslate -On DISMAN-PING-MIB::pingProbeHistoryTable
.1.3.6.1.2.1.80.1.4
Output on the server, when I do this:
snmpget -v2c -c public 192.168.5.21 sysDescr.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux snmp-agent 4.10.0-33-generic #37~16.04.1-Ubuntu SMP Fri Aug 11 14:07:24 UTC 2017 x86_64
But when I run snmpget, from the server, I get this error for all the three:
snmpget -v2c -c public 192.168.5.21 DISMAN-PING-MIB::pingCtlTable.0
DISMAN-PING-MIB::pingCtlTable = No Such Object available on this agent at this OID
Output when specified the OID's:
snmpget -v2c -c public 192.168.5.21 .1.3.6.1.2.1.80.1.2
DISMAN-PING-MIB::pingCtlTable = No Such Object available on this agent at this OID
NOTE: I have already seen these posts with no luck for me. add new mib master agent snmpget-no-such-object... and snmpget-returns-no-such-object...
UPDATE 2:
When I do snmpwalk from the server, I get:
root@snmp-server:# snmp-server:# snmpwalk -v 2c -c ncs -m DISMAN-PING-MIB 192.168.5.22 .1.3.6.1.2.1.80
DISMAN-PING-MIB::pingObjects.0 = INTEGER: 1
DISMAN-PING-MIB::pingFullCompliance.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = STRING: "/bin/echo"
DISMAN-PING-MIB::pingMinimumCompliance.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = ""

DISMAN-PING-MIB::pingCompliances.5.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = INTEGER: 5
DISMAN-PING-MIB::pingCompliances.6.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = INTEGER: 1
DISMAN-PING-MIB::pingCompliances.7.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = INTEGER: 1
DISMAN-PING-MIB::pingCompliances.20.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = INTEGER: 4
DISMAN-PING-MIB::pingCompliances.21.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = INTEGER: 1
DISMAN-PING-MIB::pingIcmpEcho.1.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = ""
DISMAN-PING-MIB::pingIcmpEcho.2.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = ""
DISMAN-PING-MIB::pingIcmpEcho.3.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = INTEGER: 1
DISMAN-PING-MIB::pingIcmpEcho.4.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = INTEGER: 0

So accordingly when I follow the output of snmpwalk, I get:
root@snmp-server:# snmpget 192.168.5.22 DISMAN-PING-MIB::pingFullCompliance.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48
DISMAN-PING-MIB::pingFullCompliance.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 = Wrong Type (should be INTEGER): STRING: "/bin/echo"
I don't understand why I have such a long OID? What is pingFullCompliance.15.46.49.46.51.46.54.46.49.46.50.46.49.46.56.48 ? Where am I going wrong? Can anyone please point me in the right direction... Thank you.
