Bug#894316: intentional behaviour

Show all headers | View raw

Hi,

This is not a bug, it's intentional behaviour. The help text states:

	dev <devname> scan trigger ... [ssid <ssid>*|passive]
		Trigger a scan on the given frequencies **with probing for the given
		SSIDs** (or wildcard if not given) unless passive scanning is requested.
		Duration(in TUs), if specified, will be used to set dwell times.

("**" highlight mine, some stuff elided with "...")

This is correct, and should be implemented this way in hopefully all
drivers, certainly all the ones I know of.

However, this does *not* mean that it will also *show* only networks
with the given SSID(s), it merely means that the underlying driver only
*sends probes* for those SSID(s). All other networks discovered at the
same time, by passively picking up other beacons or probe responses, or
perhaps even by a previous scan, will still be shown.
