This works just using the "Start" +and "Stop" Pushbuttons in the Wellenreiter GUI. If this doesn't work, +then use the following strategy: + 1. Place card in monitor mode. This is device dependent. Caution: Don't do this while you're logged in via ssh or otherwise using the wireless interface - your connection will freeze: The card can't be used normally when sniffing! - For most orinoco-based cards this can be done using + For most orinoco-based cards this can be done using either 'iwpriv <interface> 2' or 'iwpriv <interface> 2 1'. You can check if this works, by calling 'ifconfig <interface>'. If you see 'Protocol: UNSPEC' and an unusual long MAC-Address, then your card has been successfully set to the monitor mode. 2. Start a channel hopper. A wireless card has several channels (e.g. radio frequencies) here it can listen for beacons. Beacons are management data frames from other stations. Remember, this is radio transmission, so the card has to be "tuned" to a certain channel to be able to receive the beacons. In order to scan the complete frequency spectrum and thus be able to detect all available stations, you have to 'hop' through the channels frequently. You can do this manually (e.g. with 'iwconfig') [hahaha] or you can use a channel hopper. diff --git a/noncore/net/wellenreiter/gui/wellenreiter.cpp b/noncore/net/wellenreiter/gui/wellenreiter.cpp index b22c5cc..4ee9a35 100644 --- a/noncore/net/wellenreiter/gui/wellenreiter.cpp +++ b/noncore/net/wellenreiter/gui/wellenreiter.cpp @@ -99,33 +99,33 @@ Wellenreiter::Wellenreiter( QWidget* parent, const char* name, WFlags fl ) if ( daemon_fd == -1 ) { logwindow->log( "(E) Couldn't get file descriptor for commsocket." ); } else { int flags; flags = fcntl( daemon_fd, F_GETFL, 0 ); fcntl( daemon_fd, F_SETFL, flags | O_NONBLOCK ); QSocketNotifier *sn = new QSocketNotifier( daemon_fd, QSocketNotifier::Read, parent ); connect( sn, SIGNAL( activated( int ) ), this, SLOT( dataReceived() ) ); } // setup GUI connect( button, SIGNAL( clicked() ), this, SLOT( buttonClicked() ) ); - button->setEnabled( false ); + // button->setEnabled( false ); netview->setColumnWidthMode( 1, QListView::Manual ); if ( manufacturerdb ) netview->setManufacturerDB( manufacturerdb ); } Wellenreiter::~Wellenreiter() { // no need to delete child widgets, Qt does it all for us delete manufacturerdb; } void Wellenreiter::handleMessage() { @@ -222,63 +222,79 @@ void Wellenreiter::buttonClicked() addNewItem( "adhoc", "ELAN", "40:03:63:E7:56:E2", false, 3, 20 ); */ if ( daemonRunning ) { daemonRunning = false; logwindow->log( "(i) Daemon has been stopped." ); button->setText( "Start Scanning" ); // Stop daemon - ugly for now... later better system( "killall orinoco_hopper" ); system( "killall wellenreiterd" ); - // FIXME: reset the card trying to get into a usable state again + // get configuration from config window - // for now, just message the user + const QString& interface = configwindow->interfaceName->currentText(); + const QString& cardtype = configwindow->deviceType->currentText(); + const QString& interval = configwindow->hopInterval->cleanText(); + + // reset the card trying to get into a usable state again + + QString cmdline; + cmdline.sprintf( "iwpriv %s monitor 1", (const char*) interface ); + system( cmdline ); + cmdline.sprintf( "iwpriv %s monitor 1 6", (const char*) interface ); + system( cmdline ); + cmdline.sprintf( "ifconfig %s -promisc", (const char*) interface ); + system( cmdline ); + cmdline.sprintf( "killall -14 dhcpcd" ); + system( cmdline ); + cmdline.sprintf( "killall -10 udhcpc" ); + + // message the user - QMessageBox::information( this, "Wellenreiter/Opie", "You should reset your\ndevice before using it again." ); + QMessageBox::information( this, "Wellenreiter/Opie", "Your wireless card\nshould now be usable again." ); } else { logwindow->log( "(i) Daemon has been started." ); daemonRunning = true; button->setText( "Stop Scanning" ); // get configuration from config window const QString& interface = configwindow->interfaceName->currentText(); const QString& cardtype = configwindow->deviceType->currentText(); const QString& interval = configwindow->hopInterval->cleanText(); if ( ( interface == "<select>" ) || ( cardtype == "<select>" ) ) { QMessageBox::information( this, "Wellenreiter/Opie", "You must configure your\ndevice before scanning." ); return; } // set interface into monitor mode /* Global::Execute definitely does not work very well with non-gui stuff! :( */ QString cmdline; - cmdline.sprintf( "iwpriv %s monitor 2", (const char*) interface ); system( cmdline ); cmdline.sprintf( "iwpriv %s monitor 2 1", (const char*) interface ); system( cmdline ); // start channel hopper cmdline = "orinoco_hopper "; cmdline += interface; cmdline += " -i "; cmdline += interval; cmdline += " &"; qDebug( "execute: %s", (const char*) cmdline ); system( cmdline ); qDebug( "done" ); |
