Network Discovery
 

I am looking for a network discvoery tool that would show me all devices on a given network and give me their IP addresses and any other information. For example, if I walk into a company that needs my consulting services and they have no clue what the ip address of the routers, switches, etc are... I want a tool that can scan the network and give me something to go on. let me know. Thanks

Here's something for UNIX boxes -> http://www.unix.org.ua/orelly/networ...ot/ch06_02.htm

If you're looking for Windows applications, LanSurveyor seems to be pretty good.

I would need the Lansurveyor then. It looks like it would come in handy. Retail is $1000. I doubt I'll be able to find it using "other" methods but I will sure as hell try.

Uhm, switches don't have IPs - they are completly transparent to that network layer.

My 3COM swiches have IP's. Anyways, I got the program so thanks.

Nonsense. I bet you mean your 3COM router has an IP.

Managed Layer 2 switches can have IP information assigned to them for the purposes of remote management via telnet or HTTP. The keyword here is managed.

As for network discovery, consider nmap network mapping/port scanning/service fingerprinting tool. You'll have to be comfortable with working in the command-line, but nmap is a very powerful and flexible tool.

Exactly so my switches do have an IP addressed to them since they are managed.

Technically the configuration interface doesn't belong to the switch. It's a piece of hardware acting as client, housed in the same casing as the (real) switch.

And implementations of the config interface (and in particular access mode) vary: You also find configuration through serial port interface or even buttons. These types are also managed.

Funny how people will argue to the end to prove themselves right. I got what I needed from this post so thanks.
