How to know who is connected on a wireless network?

Asked by tashi

Hello,

I'd like to know what command to launch to lean witch machines are connected on a wireless network. For the moment, to know who is connected, I just sometimes look a jnettop, and so reads things about what computers says on the network, but is there a way to know who is connected on a network, not having the pass for the box?

Thanks to tell me a way to do it, or even a way to hide connections dealing about me with jnettop!

You can use nmap to sniff your networks subnet to see if there are computers connected. This will also show the wired connections too but if you ONLY use wireless you are laughing

You can also simply access your routers config page and look at the status there

nmap to sniff??? But, is it also a sniffer? I thought it was just a NetworkMAPper...
And don't you have a command to give me?

But I had no link with your "there", and moreover I have no access to the router I do use, no pass...
Maybe also someone knows a way to crack it's password? :D (I don't think it's possible, because we have I think a maximum trials per attempt...)

Your network may use a diferent subnet

10.0.0.x instead of 192.168.1.x and so on so the commands may need tweaking. Most crappy home grade routers use 192.168.0.x

Howdy Mate,

Try EtterCap. It's pretty simple to use.

sudo apt-get install ettercap

Thanks to you all,
I solved that problem now and I can connect Wirless networks it works.
Moreover, I'm using the last Ubuntu so it's quite easy.
