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. diff --git a/noncore/net/wellenreiter/gui/wellenreiter.cpp b/noncore/net/wellenreiter/gui/wellenreiter.cpp index 5575d6e..45d7142 100644 --- a/noncore/net/wellenreiter/gui/wellenreiter.cpp +++ b/noncore/net/wellenreiter/gui/wellenreiter.cpp @@ -138,131 +138,150 @@ void Wellenreiter::channelHopped(int c) void Wellenreiter::handleNotification( OPacket* p ) { QObjectList* l = p->queryList();
