Topic: Finding Network Information?

Not sure if this is the right place to ask it, but I'm currently at my parents' restaurant and on someone's unsecured network. I'm wondering if there are any terminal commands that will show me things like how many others are on the network, their PC names, etc. Just really bored and it popped into my head and now I'm really curious!

Re: Finding Network Information?

I think you need to have access to the router in order to do that.
- just remember that it's illegal to use other peoples network.

But you can try by opening a browser and type.: 192.168.1.1, and if there's  a login prompt, then type admin as user, and maybe admin as password.
In the router settings you will almost always be able to see who's connected to the router, for how long and so on.


Just keep in mind that it's illegal, so don't do anything stupid, as you can be caught

I'm pretty sure that it isn't illegal outright to use someone else's network as long as it's unsecured (cracking a secured one is a whole nother matter though). I don't use it for anything illegal. With that said, I'd rather not try admin + admin at 192.168.1.1 because then my intentions start becoming too intrusive (or that's how I feel it). Thanks for the suggestion though, I hadn't thought of that.

EDIT: Well now, this is interesting.. Thanks again for your post, it piqued my curiosity and I found something interesting. smile

Re: Finding Network Information?

Wireshark/tshark/tcpdump will probably show you any broadcast traffic on the network.  Running "avahi-browse -a" (with the appropriate packages installed) will show you any Apple Mac's using Bonjour for service discovery, etc.  Kismet might be interesting for looking at the lower level wifi stuff, and nmap will let you probe stuff you find, but it may be best to stay passive and not actively send anything smile

if you want really get interesting, then the Backtrack distro is worth a look.

Backtrack! I know a guy that uses it, and was intrigued when he told me about it. nmap sounds very interesting, but I have no idea where to start with it. Do you know any useful guides? Or maybe some for penetration testing too? I promise I'd only try it on my own network. wink
