Network Mapper

I am filled with ignorance. I cannot get The Dude network mapper to work. It gives me an error every time I scan my network and does not list any devices.

I only have a small home network with about twelve devices but I have lost track of the MAC addresses over time. I use MAC address filtering to allow access to the network, so I want to make sure the allowed MAC's are current.

And I have no idea what Router OS is. Perhaps if I knew what I was doing I could make The Dude work.

Thanks.

 

Uninstall it from control panel.
Switch off MAC addy filtering for now to allow access for all devices.

Download and install new version here at MG's, run it and test if all is positive.

Then run 'ipconfig /all' from devices and note 'physical' addy's to reset MAC if you wish.
Its not a great security feature however!

 

Thanks, Replicator. This isn't exactly what I'm looking for. Some of these things (Blu-Ray player, printer, Roku) don't have a GUI to do the ipconfig from. You can get to the MAC but it takes some drilling down, maybe going to the setup process.

Do you mean the MAC address filtering on the router isn't a great security feature? Can you explain?

Thanks.

 

If the blu-ray, printer etc are connected to your network (router) you can obtain their MAC's from the router interface in the web browser.
On my Dlink, I go to 'connected clients', click the 'edit icon' of the device in question and bingo, there is the MAC, IP etc

MAC addy filtering is a false sense of security as these addresses are easily 'spoofed' using readily available software techniques.

WPA2 is your essence security feature on your router, this should be enough!

If you want further confirmation, have a read here.

 

I am officially floored. I've been fooling with computers since 5 1/4" floppies but I guess you can never outgeek the crooks. I thought I was being clever but all I was doing was increasing the hassle for myself, keeping up with MAC addresses as they were added and removed.

Not that I think I am a likely target for a drive-by suburban hacking, but now I just can rely on WPA2 and a good passphrase. Thanks a lot.

 

You hit the nail on the head......a well thought password is key to your networks security using wpa2

Brute-force attacks are the most common way attackers attempt to break your pass for access to your WiFi network.
A great password using Capitals, letters, numbers and characters (of a decent length), will certainly shore you up well.
If someone ran a bruteforce scan 24/7 against this type of security, its highly unlikely they would crack it even in there own lifetime!
After a few hours with no success, they would simply move on to an easier target anyway!

Good Luck
