【问题描述】：
我需要通过 snmp 检索信息，然后使用这些信息在 Unity 中创建某种图形应用程序。
我找到了 SnmpSharp 库 http://www.snmpsharpnet.com/
我使用这个库统一创建了一个小程序，然后我在我的 windows 机器上安装了 snmp（使用 windows 官方指南），在 localhost 上它可以工作！
现在我的问题是 如何连接到我的局域网上的其他代理？ 如何在我的其他设备（例如 linux pc）上安装代理？ 我有点困惑，因为我尝试在另一台 Windows 电脑上安装 snmp，但我无法从中检索 snmp 信息；我尝试在 linux pc 上安装 snmp 代理，但我不明白如何正确安装必须跨局域网通信的代理
这是在本地主机上工作的代码
