IWSPY(8)                   Linux Programmer's Manual                  IWSPY(8)



NAME
       iwspy - Get wireless statistics from specific nodes

SYNOPSIS
       iwspy interface
       iwspy interface [+] DNSNAME | IPADDR | HWADDR [...]
       iwspy interface off

DESCRIPTION
       Iwspy  is  used to set a list of addresses in a wireless network inter-
       face 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.

PARAMETERS
       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 func-
              tionality
