iwspy - Get wireless statistics from specific nodes
SYNOPSIS
iwspy interface
iwspy interface [+] IPADDR | HWADDR [...]
iwspy interface off
DESCRIPTION
Iwspy is used to set a list of addresses in a wireless
network interface and to read back quality of link infor
mation 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.
PARAMETERS
You may set any number of addresses up to 8.
IPADDR Set an IP address, or in some cases a domain name.
As the hardware work with hardware addresses, iwspy
will translate this 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
address and retry.
HWADDR Set a hardware (MAC) address (this address is not
translated & checked like the IP one). The address
must contain a semicolon (:) to be recognised as a
hardware address.
+ Add the new set of addresses at the end of the cur
rent 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
