iwspy - Get wireless statistics from specific nodes
iwspy interface [+] DNSNAME | IPADDR | HWADDR [...]
iwspy interface off
Iwspy is used to set a list of addresses in a wireless network interface and to read back
quality of link information for each of those. This information is the same as the one
available in /proc/net/wireless : quality of the link, signal strength and noise level.
This information is updated each time a new packet is received, so each address of the
list add some overhead in the driver.
Note the this functionality work only for node part of the current wireless cells.
You may set any number of addresses up to 8.
DNSNAME | IPADDR
Set an IP address, or in some cases a DNS name (using the name resolver). As the
hardware work with hardware addresses, iwspy will translate this IP address through
ARP. In some case, this address might not be in the ARP cache and iwspy will fail.
In those case, ping(8) this name/address and retry.
HWADDR Set a hardware (MAC) address (this address is not translated & checked like the IP
one). The address must contain a colon (:) to be recognised as a hardware address.
+ Add the new set of addresses at the end of the current list instead of replacing
it. The address list is unique for each device, so each user should use this option
to avoid conflicts.
off Remove the current list of addresses and disable the spy functionality
iwconfig(8), ifconfig(8), iwlist(8). iwpriv(8).
