Ubuntu snmp的问题

Ubuntu snmp的问题

 

Ubuntu 12.04 didn’t install the MIB files. Even if you install the SNMP applications. 

Just check the preamble of /etc/snmp/snmp.conf

 

#

# As the snmp packages come without MIB files due to license reasons, loading

# of MIBs is disabled by default. If you added the MIBs you can reenable

# loaging them by commenting out the following line.

mibs :

 

Sure, but how can I install them ?

 

Fortunately there is a package to deal with that.

 

$ sudo apt-get install snmp-mibs-downloader

 

It will download the IETF MIB files and install them under the usual /usr/share/mibs/

 

If for any reason you don’t see it happen force it with

 

$ sudo download-mibs

 

You can repeat this command later to update any new MIB file.

 

安装完成后，测试

 

snmpwalk -v 2c -c public localhost

解决办法：

 

#!/bin/bash

for i in /usr/share/mibs/ietf/IPSEC-SPD-MIB /usr/share/mibs/ietf/IPATM-IPMC-MIB /usr/share/mibs/iana/IANA-IPPM-METRICS-REGISTRY-M

IB /usr/share/mibs/ietf/SNMPv2-PDU

do

mv $i /usr/share/mibs

done

 

另外snmpwalk -v 2c -c public 192.168.1.1 mem可以使用，snmpwalk -v 2c -c public 192.168.1.1 cpu不能使用，因为不存在cpu这个logical name，所以，直接使用OID，snmpwalk -v 2c -c public 192.168.1.1 .1.3.6.1.2.1.25.3.3.1.2

 

snmpwalk -v 2c -c public 192.168.1.1 .1.3.6.1.2.1.25.3.3.1.2
