Active Scanning or Passive Scanning

Dear,

How to actually check the WiFi card whether it is in active scanning or passive scanning?

Regards

I found this. I don't know what wireless card/driver you have, but your setup may show similar information:

---snip---
Used to provide details on the channel capabilities enabled by the adapter.

Example:

% cat /sys/bus/pci/drivers/ipw3945/*/channels

Displaying 13 channels in 2.4Ghz band (802.11bg):
1: 17dBm: BSS, IBSS, active/passive.
2: 17dBm: BSS, IBSS, active/passive.
---snip---
