An easy to use, GTK/Perl-based wireless sniffer/scanner with enhanced features.





Wellenreiter is a gtkperl program that makes the discovery and auditing of 802.11b wireless networks as easy as possible.

For discovery of the accesspoints / networks / ad-hoc cards, Wellenreiter has an amazingly easy to use scanner window, which searches for any accesspoint within the range of the scanning device.

It detects and differentiates essid broadcasting and non-broadcasting wireless networks. The manufacturer is detected by the device's MAC address. WEP and BSS / IBSS detection is also implemented.

Detecting essid's of non-broadcasting networks is possible and gps support is also built in (Requires gpsd). Wellenreiter is the first Wireless scanner that does not need to be configured anymore.

Its amazing autodetection takes care about taking the correct cardtype and using the right comands. Lucent/Orinocco, Cisco and Prism2/2.5 (WLAN-NG drivers) based Cards are supported now. NO, hosap drivers actualy don't work in this version, stay tuned for that.

The Networks with a red symbol are "non-essid-broadcasting" ones. This means the accesspoint does not send out the essid network name for security reasons.

Non-broadcasting networks can be only detected by using the raw-sniffing mode. Green symbols are shown for a broadcasting network.

The distinction between WEP/cleartext sending accesspoints is indicated by the word "ON" or "OFF" and a little open or closed lock icon. AD-Hoc stations (BSS) have different icons than real accesspoints (IBSS).

Channels that are holding new objects are colored red until you select it. The pkt indicator on the right side of the listview alternates between the two characters "+" and "*". When it alternates, this accesspoint is sending traffic.

So its a traffic indication. If you click on an object in the treeview you will get the detail window. This window refresh after a while. Keep it open to see arp and dhcp traffic.

Use the logwindow to take care of all your findings and the trafficwindow to see what packets are coming in. Oh, one word about saving, it automaticly saves a dump and a savefile to your homedrive.

Here are some key features of "Wellenreiter":

· Cisco based cards
· Lucent based cards
· Prism2 based cards (Wlan-ng drivers only)

What's New in This Release:

· Added the Userguide in the docs diretory.
· Raised the packetcapture lenght from 400 to 65535 wich should not truncate anymore.
· Still adding some smaller fixes. Added a patch for better detection of prism2 based PCI and usb cards.
· Choose card window fixed.
· IBSS/ESS text in window is now correct, sorry for that.
