Usage:
echo "[ARGS]" > setuserscan
where [ARGS]:
- chan=[chan#][band][mode] where band is [a,b,g] and mode is
- blank for active or 'p' for passive
bssid=xx:xx:xx:xx:xx:xx specify a BSSID filter for the scan
ssid="[SSID]" specify a SSID filter for the scan
keep=[0 or 1] keep the previous scan results (1), discard (0)
dur=[scan time] time to scan for each channel in milliseconds
- probes=[#] number of probe requests to send on each chan
type=[1,2,3] BSS type: 1 (Infra), 2(Adhoc), 3(Any)
- Any combination of the above arguments can be supplied on the command line.
- If the chan token is absent, a full channel scan will be completed by
- the driver. If the dur or probes tokens are absent, the driver default
- setting will be used. The bssid and ssid fields, if blank,
- will produce an unfiltered scan. The type field will default to 3 (Any)
- and the keep field will default to 0 (Discard).

Examples:
- 1) Perform an active scan on channels 1, 6, and 11 in the 'g' band:
- echo "chan=1g,6g,11g" > setuserscan
+ 1) Perform a passive scan on all channels for 20 ms per channel:
+ echo "dur=20" > setuserscan
- 2) Perform a passive scan on channel 11 for 20 ms:
- echo "chan=11gp dur=20" > setuserscan
+ 2) Perform an active scan for a specific SSID:
+ echo "ssid="TestAP"" > setuserscan
- 3) Perform an active scan on channels 1, 6, and 11; and a passive scan on
- channel 36 in the 'a' band:
-
- echo "chan=1g,6g,11g,36ap" > setuserscan
-
- 4) Perform an active scan on channel 6 and 36 for a specific SSID:
- echo "chan=6g,36a ssid="TestAP"" > setuserscan
-
- 5) Scan all available channels (B/G, A bands) for a specific BSSID, keep
+ 3) Scan all available channels (B/G, A bands) for a specific BSSID, keep
the current scan table intact, update existing or append new scan data:
echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan
- 6) Scan channel 6, for all infrastructure networks, sending two probe
- requests. Keep the previous scan table intact. Update any duplicate
- BSSID/SSID matches with the new scan data:
- echo "chan=6g type=1 probes=2 keep=1" > setuserscan
+ 4) Scan for all infrastructure networks.
+ Keep the previous scan table intact. Update any duplicate BSSID/SSID
+ matches with the new scan data:
+ echo "type=1 keep=1" > setuserscan
All entries in the scan table (not just the new scan data when keep=1)
will be displayed upon completion by use of the getscantable ioctl.
