I manage a small business network, and would like to put some simple monitoring in place (to avoid things like rogue wireless APs), but don't want to deny access by default, which is the way most of the stuff I've seen works.
Ideally, I'm thinking something that keeps track of MAC addresses seen by the firewall/router (running linux, of course!), compares the MAC address with a list of 'known' addresses, and e-mails me when a new MAC shows up would work pretty well. Sniffing ARP packets should be a good way to collect MAC addresses without requiring excessive CPU resources, sniffer ports on my switch, etc.
Does this sound reasonable to anyone else?
Does anyone know of a pre-existing program that would do this, or is it something I'm going to have to roll on my own?
Any better ideas for keeping track of what's actually plugged in and talking on a network while still 'playing nice' and generally trusting the user base?

I'd personally modify some netreg-type software... Then any unknown/new MAC would be redirected to a login page where they can provide some authentication or even just a text area description "This is Joe's new laptop". I don't think most people would consider it a nuisance, but it might have issues with random non-computer devices...
I prefer grip myself...I think fc4 may rip out a lot of support for mp3 because of the license though...might have to roll your own or use a 3rd party repository to install grip.

I am using FC4 and the packaged ripping app's all have bugs in them.
My biggest criteria is that my mp3 player does not recognize .ogg files so I would prefer it generate .mp3 files.

RedHat hasn't had support for MP3s since RedHat version 8. I wouldn't expect FC* to have support for MP3s either.

I used Grip under FC3 and loved it, but can't get it to work properly under FC4.
All the mp3 compatible encoders respond with an error "invalid encoder executable, check your encoder config". The config looks OK as far as I can tell.
The only encoders that work are Ogg Vobis and Bladeenc. I can get bladeenc to produce a file with an .mp3 extension, but the mp3 player chokes because the files is still an ogg vobis file. I just don't see how to get an mp3 format file to satisfy the player.
I also noticed the following error when I run Grip from a terminal window : (grip:3176): Gdk-WARNING **: gdk_property_get(): length value has wrapped in calculation (did you pass G_MAXLONG?)
Not really sure where to fix this one. I will look into it some more, but if anyone is familiar with it and can point the right direction it would save me some time.

Check out this page:

Look down in the middle in the section called 'GRIP and MP3s'.
Also, you'll need to make sure you have a ripper than will rip MP3s installed. There is no such encoder installed by default in Fedora systems, due to the patent problems.

Don't worry about this error as it has nothing to do with your problem.

KDE. Open your CD, browse to the "MP3" folder, and copy the files somewhere.

Sounds like RedHat.
P.S. Don't hijack threads.
