识别非计算机网络设备? [英] Identify a non-computer network device?

问题描述

我目前正在研究一个程序，该程序可以扫描我的网络并发现网络上的计算机和设备.我使用各种操作在发现的设备上查找数据，但希望将网络设备与计算机区分开.我想知道是否有人知道我该怎么做?

I'm current working on a program that scans my network and discoveres computers and devices on the network. I use various operations to find data on the devices I discover, but want to distinguish the network devices from computers. And I'm wondering if anyone knows how I could do this?

我对SNMP有点了解，并尝试连接到我的网络打印机，路由器和调制解调器.但是我似乎只能连接到打印机，路由器或调制解调器都没有响应.

I looked a bit at SNMP, and tried connecting to my network printer, router and modem. But I seem to only be able to connect to the printer, neither the router or modem responds.

还有另一种方法来识别IP地址属于哪种设备?

Is there another way to identify what kind of a device an IP address belongs to?

推荐答案

使用诸如 nmap 这样的命令行工具可以用手指打印可以为您提供各种信息的设备.

Using a command line tool such as nmap you can finger print the device which can give you all sorts of information.

也许您可以通过c#调用nmap并读回响应.

Perhaps you can call nmap via c# and read back the response.

另一种选择是查找给定MAC地址的网络芯片供应商.但我不确定能为您提供多少细节.

Another alternative is to look up the network chip vendor of a given MAC address. But I'm not sure how much detail that will give you.

以下是nmap网站中的示例:

Here is the example from the nmap site:

# nmap -O -v scanme.nmap.org

Starting Nmap ( http://nmap.org )
Nmap scan report for scanme.nmap.org (64.13.134.52)
Not shown: 994 filtered ports
PORT    STATE  SERVICE
22/tcp  open   ssh
25/tcp  closed smtp
53/tcp  open   domain
70/tcp  closed gopher
80/tcp  open   http
113/tcp closed auth
Device type: general purpose

Uptime guess: 11.433 days (since Thu Sep 18 13:13:01 2008)
TCP Sequence Prediction: Difficulty=204 (Good luck!)
IP ID Sequence Generation: All zeros
