Kismet is a tool for wireless sniffing (just viewing what’s already passing through the air). And KisMAC is the OSX version. Best part about KisMAC is the Apple Airport Extreme card drivers for both Active and Passive support. Active, meaning you can see but can’t collect, and passive meaning you can see and collect.
So if your on OSX and you want to see the wireless in your area and collectively watch what’s be sent around, getting KisMAC is a good starting place.

Little Snitch – OS X firewall application

With almost every type of application now making network connections without user approval it is vital to have a firewall application that is able to alert you when network access is being attempted from your machine out to the net. Most basic firewall settings for OSX allow outbound connections with no alerts or blocking.

You can either learn the ipfw command or just download Little Snitch.

OS X by itself comes with some basic unix type stuff, which Terminal allows you access.

There are editors:

• vi / vim
• pico
• emacs

There are shells:

• bash (Bourne-Again Shell)
• ksh (korn shell)
• tcsh (the TENEX C Shell)
• DOS

But this is just the tip of the ice-berg… There is a lot more that the Unix core of OS X can bring to you.

There are a couple things you need to download before this all starts happening for you.

1. X11 (Good-bye terminal, hello X Window System)
2. ADC (Sign-up up for Apple Developer Connection. After signing-up, login and click ‘Developer Tools’ on the right-column under ‘Downloads’. Now download the most recent version of Xcode Tools. It’s a fairly large file [around a gig])
3. FINK (Has a collection of ported [modified] version of open-source Unix apps for OS X [Darwin]. It also comes with many command tools for installation)
4. FINK Commander (Aqua-GUI for using Fink. Makes life easy.)
5. DarwinPorts (Like Fink. Make sure to download the DMG file)
6. Port Authority (Like Fink Commander, but for DarwinPorts)

And… we install. Install in the same order.

Now we can install Unix apps (and Librarys) from Port Authority and Fink Commander. Also note to execute downloaded Apps, you have to open X11; for darwinports you type ‘cd /opt/local/bin’, for fink you type ‘cd /sw/bin’ and then ‘./NameOfApp’

Having trouble opening and playing files in Quicktime? Quicktime doesn’t, by default, support that many codec

There are some very good alternative media players available:
VLC media player
MPlayer

These players support a vast-number of codecs. VLC also has amazing support for dumping streaming video, loading video over LAN and several other high-end networked video operations.
