root@ubuntu:~# cat /etc/issue
Ubuntu 12.04.1 LTS \n \l
安装：
apt-get install snmpd
配置：
修改/etc/snmp/snmpd.conf文件;
屏蔽第15行
#agentAddress udp:127.0.0.1:161
打开第17行
agentAddress udp:161,udp6:[::1]:161
最下面添加如下信息：
com2sec notConfigUser default public
group notConfigGroup v1 notConfigUser
group notConfigGroup v2c notConfigUser
view systemview included .1
access notConfigGroup "" any noauth exact systemview none none
syslocation 7 floor room 192.168.1.191
syscontact Root xzy
pass .1.3.6.1.4.1.4413.4.1 /usr/bin/ucd5820stat
启动snmpd服务
service snmpd restart
安全：
为了更好做到安全策略,我们现在配置snmp只允许某个ip连接。
vim /etc/hosts.allow文件，添加如下信息：
snmpd:xx.xx.xx.xx:allow
snmpd:all:deny
系统介绍：

安全：
修改服务器iptables防火墙：
vim /etc/sysconfig/iptables
-A INPUT -s xxxx/xx -p udp -m udp --dport 161 -j ACCEPT
修改snmp的允许连接的ip：
vim /etc/hosts.allow
snmpd:xx.xx.xx.xx:allow
snmpd:all:deny
系统介绍：
安装：
开始-->控制面板-->添加或删除程序
添加/删除Windows组建(A)-->管理和监视工具
简单网络管理协议(SNMP) 打勾-->确定
中途可能会提示放入光盘，在光驱内放入win2003光盘即可
配置：
我点电脑-->右键-->管理
服务和应用程序-->服务
找到右边的SNMP Service服务双击选择属性-->安全分别添加团体名和信任主机ip
安装配置完成
