snmp

Ubuntu解决不能远程访问snmp协议的

需要远程使用snmp,发现ubuntu9.04上不支持远程访问,google了一下解决办法如下
编辑 /etc/default/snmpd

$sudo vi /etc/default/snmpd 
# This file controls the activity of snmpd and snmptrapd
# MIB directories.  /usr/share/snmp/mibs is the default, but
# including it here avoids some strange problems.
export MIBDIRS=/usr/share/snmp/mibs

# snmpd control (yes means start daemon).
SNMPDRUN=yes

# snmpd options (use syslog, close stdin/out/err).
#SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I -smux -p /var/run/snmpd.pid'

去掉snmpdopts中的127.0.0.1绑定

cacti通过snmp监控ubuntu9.10网卡流量遇到的问题

折腾无线,snmp总是链接不上,debug报如下错误;

+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/cacti/resource/snmp_queries/interface.xml'
+ XML file parsed ok.

谷歌百度,终于找到解决办法,记录之。。。

bear@njava:/var/www/njava$ sudo vi /etc/snmp/snmpd.conf 
# First, map the community name (COMMUNITY) into a security name
# (local and mynetwork, depending on where the request is coming
# from):
# sec.name  source          community
#com2sec paranoid  default         public
#com2sec paranoid  default         njava
com2sec readonly  default         public
bear@njava:/var/www/njava$ sudo /etc/init.d/snmpd restart
