我要做一个基于SNMP的网络性能采集软件
找到了SNMP4J的开发包但是不会用
那位大哥能给个例子指导一下
谢谢了

自己先顶一下
有没有人知道SNMP这个协议中的
MIB库方面的知识
网上这方面的东西很少阿
郁闷中

一点都不了解。

我要坚持
我现在SNMP的协议也装了 MIB库也有了
但是MIB的OID又让人很迷惑
谁有MIB遍历或 OID经验的
给点建议阿~~~~`

做好了,教教我

孤陋寡闻了

ls啥时候回来?

有没有用过SNMP4J的
看看这个程序阿
给点建议撒

import org.snmp4j.*;
import org.snmp4j.mp.*;
import org.snmp4j.smi.*;
import org.snmp4j.transport.*;
import org.snmp4j.event.ResponseEvent;

SNMP4J 是我从网上下的一个开发包怎么把它导入到 classpath里面？？？？
这样用import总是报错找不到org.snmp4j这个包。。。

把SNMP4J.rar包放到c盘根目录，在命令行输入
编译：
c:\>javac -classpath .;c:\SNMP4J.rar Check_for_machine_test.java
运行：
c:\>java -classpath .;c:\SNMP4J.rar Check_for_machine_test
