Who is on my wireless network and......

[Road Runner]

Ok I know I am gonna get flamed and have to go sit in the corner with a Dunce hat on but here goes.

I "share" my internet connection at my day job with folks I rent to in the next suite.

We have a Netopia DSL wireless modem/router combo.It was provided by the internet provider.

There is an apartment complex behind my building and I believe others are using our system.......I know I know.....I can enable encryption.

What I am asking is if there is a way to not only monitor WHO is using....AND also log their time.....what bandwidth they used etc etc.

Curiosity is the main thing........

Of course I prefer a free application but don't mind spending a buck or two iff need be.

Many Thanks

If your router doesn't do it, you're going to have to do a man in the middle attack on them and then use something that monitors their activity such as wireshark. And I believe you'd only be able to do this to one connection at a time.

Rather than spy on them, why don't you just enable security? I'm not flaming, but that seems like the more reasonable thing to do instead of spying on them.

There are a few things you can do, but if you know who's computers should be on your network, capture some packets with WireShark or Ethereal and filter by MAC.

I agree Sir,
Security enable is the way to go......but my curiosity of how many free loaders there was gets the best of me.

I'm not interested in spying on their content......just how many are riding for free.

 

[DohIForgot]

Quickest and easiest way I can think of is to get a MAC address count. Anymore than your computers and the 2-3 next store and you'll figure it out real quick.

If you want to see whats going on download a program called wireshark

http://www.wireshark.org/

leave a computer on connected to your network, run wireshark and then in a couple of days turn off WireShark and SEE what they where doing.

There is plenty of information on how to use the program.....

also posted not too long ago, Autoscan-network is good for this

Many things can be done.

I believe that router has SNMP (google it), if so you can monitor traffic and connected clients.

I am going to get me one a them super wi fi antenna and get me some o' that too,lol

kismit is a great way to go too.

I feel like pointing out that if they are doing something illegal with your connection you cold be held liable for it. Like pirating movies/music/software or child porn. It's rare and unlikely and you may be able to prove it wasn't your PC that downloaded the content but do you really want to deal with that?

Mighty Fine Suggestions Guys

Just the kind of stuff I was hoping for.

I will be using encryption.....thats the "makes best sense" approach.

I just cant help but seeing just how many folks are using my connection.After all whats wrong with curiosity ?????

It only kills cats and chickens when they cross the roadway

Sounds like you got your answer Roadrunner, but for others who find their way to this thread, there is also WallWatcher to closely monitor compatible router logs. While Netopia is not presently supported, all of these are:

2Wire, 3Com, Actiontec, Adtran, Airlink, Asante, Astaro, Asus, Bewan, Billion, Bintec, Buffalo, Checkpoint, Cisco, Cyberguard, D-Link, Draytek, Edge-Core, Edimax, Fortigate, Fortinet, Gnatbox, Hotbrick, IPCop, IPTables, ITServ, Juniper Networks, Level One, Linksys, Lucent, m0n0wall, Netgear, Netscreen, OpenBSD, ParkerVision, pfSense, Servgate, SMC, Smoothwall, Sonicwall, Speedstream, Squid, Symantec, Trendnet, Untangle, US Robotics, WatchGuard, Westell, Xincom, XroadsNetworks, Zoom, and ZyXEL

Wallwatcher would let you not only see what LAN IP addresses are sending/receiving traffic, it would also allow you to see what foreign IP address and port # were in use.

Screenshots and details here: http://www.wallwatcher.com/

autoscan will do everything that you need I think.

you can also tell it to alert you when a new user comes on.

 

[NickCat11]

+1 for autoscan.......

You cannot be held liable if you have an unsecured wireless network. It has been tested and proven in court

True, but after recording the IP and serving a supoena on your ISP, it's your door they're going to be knocking on first, and your systems that will be under unwelcome scrutiny until they're satisfied that it really wasn't you who was surfing for kiddie porn or whatever other nefarious activity tickled the legal synapses.




BTW: nice to see you didn't really leave. I was sad, now I'm happy.

 

[NickCat11]

That would be like holding you liable because you dropped your wallet, someone found it and bought cocaine with the money

I hate when that happens....
