2004-??-?? Michael Lauer <mickey@Vanille.de>
+ * Added parsing of control frames. Display stations sending them SSID "???" for now.
* Added command line option "-nocheck" to skip non-root and dhcp tests
* Improved the speed reading the manufacturer list
* GPS coordinates are now presented in the DMS (as opposed to decimal) format
2003-12-18 Michael Lauer <mickey@Vanille.de>
* Released as Version 1.0.2 (Development Snapshot)
* Added automatic uploading of capture files to "The Capture Dump" site at
http://www.Vanille.de/projects/capturedump.spy
* Initial reading of the manufacturer database happens now in background
* Removed deprecated setMonitorMode() API ==> Use setMode( "monitor" ) now.
The monitor mode now tries to use the standard IW_MODE_MONITOR first. If that
doesn't work, it falls back to using the proprietary iwpriv commands
2003-11-30 Michael Lauer <mickey@Vanille.de>
* Released as Version 1.0.1 (Development Snapshot)
* Fixed ARP decoding for wired networks.
Interestingly, 802.11 encapsulates these in IP packets, while wired ethernet just tags the type_of_protocol.
* Added reading GPS data from a gps daemon.
* Started preparations for utilizing Wellenreiter II in wired networks.
* Implemented persistant configuration interface and retriggerable auto detection.
* Added QCOP interface for talking to opie-networksettings.
* Added parsing of DHCP packets and detecting DHCP servers.
* Overhauled the configuration window and started with the customizable event system.
* Added disabling the screensaver.
* Added automatic opening and scrolling to the network tree if a new station appears.
2003-05-10 Michael Lauer <mickey@Vanille.de>
* Released as Version 1.0 (Stable)
* Added restarting the dhcp client if having killed it before.
* Decouple dump files from live capture to shift control over 'what' is dumped to applications.
2003-05-05 Michael Lauer <mickey@Vanille.de>
* Released as Version 1.0-RC1 (Release Candidate)
* Fixed rare segfaults while sniffing and operating the GUI simultaenously.
* Parse more data packets and detect more participating stations.
* Added live graph window showing the signal strength on all channels.
* Added parsing ARP packets and identifying IP addresses of participating stations.
* Added parsing with optionally enabled PRISM headers (signal strength).
2003-04-12 Michael Lauer <mickey@Vanille.de>
* Released as Version 1.0 (Beta)
* GUI enhancements in the Menubar and the Toolbar.
* Improved keyboard handling.
* Added sanity checks for running Wellenreiter II as non-root or with dhcp clients in the background.
* Add writing and replaying of libpcap compatible capture files.
2003-04-08 Michael Lauer <mickey@Vanille.de>
* Released as Version 0.2 (Alpha)
* Closed memory leak in packet capturer.
* Fixed client stations appearing under essid as access points.
* Fixed false WEP reporting in some cases.
* Started with inspecting data packages.
* Add detecting associated client stations in infrastructural networks (if they transmit data).
* Worked around buggy hostap drivers writing past fixed-length-structures on arm.
* Added dynamic checking of available private ioctls.
* Added a saveable hex window for packet dissection.
2003-03-30 Michael Lauer <mickey@Vanille.de>
* Released as Version 0.1 (Alpha)
2003-03-25 Michael Lauer <mickey@Vanille.de>
* Rewrote Wellenreiter II from scratch - including the sniffing engine.
* Beacon inspection works and finds ad-hoc networks and managed networks.
