Did not find 'zeroDotZero' in module SNMPv2-SMI

  • 772

I have a perl script that searches through our switches to find which one hosts a given IP address; this script uses net-snmp libraries to poll through a daisy-chain of ethernet switches (think core / distribution / access) until it finds the correct switch where the host is connected.

This script works fine on most of our linux machines, but I have one that that throws STDERR messages griping about missing 'zeroDotZero' in SNMPv2-SMI

How can I stop the error messages?

    The default net-snmp copy of SNMPv2-SMI has a definition for zeroDotZero...

    [mpenning@lnxlmf ietf]$ cd /usr/share/snmp/mibs/
[mpenning@lnxlmf mibs]$ grep zeroDotZero SNMPv2-SMI.txt
zeroDotZero    OBJECT-IDENTITY
[mpenning@lnxlmf mibs]$

    It turns out that I had installed an old copy of SNMPv2-SMI.my in my Cisco MIBs directory... this copy of SNMPv2-SMI.my did not have zeroDotZero and was over-riding net-snmp's copy, so I deleted it.

    [mpenning@lnxlmf mibs]$ cd /usr/share/snmp/mibs/cisco/
[mpenning@lnxlmf cisco]$ grep zeroDotZero SNMPv2-SMI.my
[mpenning@lnxlmf cisco]$ sudo rm SNMPv2-SMI.my

    Now the script runs without issues...

    [mpenning@lnxlmf ~]$ perl findhost2.pl 192.0.2.29
192.0.2.29, 192.0.2.29, 0:27:e:22:9a:d5, core-switch2, 7/37
