Não encontrou 'zeroDotZero' no módulo SNMPv2-SMI

Question

Eu tenho um script perl que pesquisa nossos switches para descobrir qual deles hospeda um determinado endereço IP; este script usa bibliotecas net-snmp para pesquisar através de uma cadeia de comutadores Ethernet (pense no núcleo / distribuição / acesso) até encontrar o comutador correto onde o host está conectado.

Este script funciona bem na maioria das nossas máquinas linux, mas eu tenho um que envia mensagens STDERR reclamando da falta de 'zeroDotZero' em SNMPv2-SMI

Como posso parar as mensagens de erro?

    

Answer 1

A cópia net-snmp padrão de SNMPv2-SMI tem uma definição para zeroDotZero ...

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

Acontece que eu tinha instalado uma cópia antiga do SNMPv2-SMI.my no meu diretório Cisco MIBs ... essa cópia do SNMPv2-SMI.my não tinha zeroDotZero e estava copiando a cópia do net-snmp , então eu deletei isso.

[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

Agora o script é executado sem problemas ...

[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
