Who's On My Network?

[dakineyj]

How about until you find something, you make a web clip widget of section of page from your router that shows that info and put it on your dashboard.

Edit: Oh, guess you can't do that with airport...

Try this, I found it a couple years ago, from the sounds of it, its exactly what you are looking for

Download IP Scanner for Mac - Displays machine names, users, IP numbers of Macs on your network. MacUpdate Mac Network Software Downloads

Stretch, thanks for the idea. I checked this out. It does look pretty promising but upon reading the user reviews it seems it generally works well for MACs only. Still, I really appreciate posting the link - thanks!

Mac OS X Software

macsniffer will give you an idea who and what are using your network

Thank you louishen. Interesting program, but not sure it's what I'm looking for. Thank you for the post!

Anyone use nmap?

nmap is a open source tool for network exploration and security auditing.
You can use it to see who is on your network, among other things.

nmap -O 192.168.11.*

will return all connections that start with 192.168.11.

Out put looks like this:

With a little knowledge of my network, I can tell exactly which devices are on the network, including networked printers, network bridges, and computers with their OS listed.

The list above tells me my wife's PC running Windows XP SP2 is on, her son's Dell is on, my Mac is on, the wireless bridge is up and running, two printers are on, Samsung and HP, and the Buffalo router is on also.

If security such as WEP or WPA or Leap is used, it is difficult for an outsider to use your internet. It takes a considerable effort to break the key and get it. It is just not worth it to get free internet access.

Also, some routers allow MAC address filtering. It allows you to list devices by their MAC addresses that you specifically allow access. This alone will block any neighbor. However, the WEP key, etc, encrypts your wireless traffic so no one can read it. It is very wise to enable encryption on a wireless router.

i use WakeOnLan and its free.

 

[uzid_427]

whos on your wifi?

If I understand you correctly what you want to do is, from your mac, open your applications folder, select the utilities folder, and the select airport utility. On the left, highlight the desired network ie. AirportExtreme, then select the manual setup button and make sure you are on the summary tab. From here it looks like a bunch of vague and very basic information, but each item can be clicked on to obtain more info - took me a sec to figure out because the highlights are not obvious. To see a list of everyone using your network, move the curser over the wireless clients and click. From here you should be given all the mac addresses of everyone using the network as well as an already readable log saving you the export trouble.

On a side note, any computer connected to the same network you are on at any given time, should be displayed on the sidebar in finder under the shared section. Unless he knows how to make his machine "stealthy". Im not sure as to the difficulty on hiding your computer, but I do know that hacking even the best wireless encryptions is not difficult given the fact that there are several shareware programs that do all the work for you. So all those who are under the impression that they are safe because they have a good password are still at risk

 

[jb112]

Use KisMac, I use it and it's great. It even has the option to kick users out of your network. Link

 

[IvanLasston]

I haven't found how to do that on my Time Capsule (which has the Airport Extreme). Partially for that reason, I keep my DIR-655 as the primary router and use the TC only as a bridge. Do have the TC hard wired to the D-Link at the opposite end of the house, so I'm covered with a network from each router and can easily switch between them as I move from one side of the house to the other.

Even in bridge mode you should be able to see who is connected. In Airport Utility -> after clicking on your device -> there is a summary page. If you click Wireless clients you can see who is connected and the signal to noise, as well as rate and type. It is by MAC address so you'll need to know all the valid MAC addresses to know if something doesn't belong.

Trying to answer this in as general terms as possible:-
Go in to your router status page, go to LAN/WLAN and look for list of devices or similar. That gives you everything, the LAN list showing everything connected by ethernet (including Airport expresses etc.) and the WLAN list (if separate) all the things connected wirelessly. Put that page up as a bookmark or weblock for your browser of choice.
