.SH DESCRIPTION
|
||
|
|
.B 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
|
||
|
|
.I /proc/net/wireless
|
||
|
|
: quality of the link, signal strength and noise level.
|
||
|
|
.PP
|
||
|
|
This information is updated each time a new packet is received, so
|
||
|
|
each address of the list add some overhead in the driver.
|
||
|
|
.PP
|
||
|
|
Note the this functionality work only for node part of the current
|
||
|
|
wireless cells.

.SH PARAMETERS
|
||
|
|
You may set any number of addresses up to 8.
|
||
|
|
.TP
|
||
|
|
.BR DNSNAME " | " IPADDR
|
||
|
|
Set an IP address, or in some cases a DNS name (using the name
|
||
|
|
resolver). As the hardware work with hardware addresses,
|
||
|
|
.B iwspy
|
||
|
|
will translate this IP address through
|
||
|
|
.IR ARP .
|
||
|
|
In some case, this address might not be in the ARP cache and
|
||
|
|
.B iwspy
|
||
|
|
will fail. In those case,
|
||
|
|
.IR ping (8)
|
||
|
|
this name/address and retry.
|
||
|
|
.TP
|
||
|
|
.B HWADDR
|
||
|
|
Set a hardware (MAC) address (this address is not translated & checked
|
||
|
|
like the IP one). The address must contain a colon
|
||
|
|
.RB ( : )
|
||
|
|
to be recognised as a hardware address.
|
||
|
|
.TP
|
||
|
|
.B +
|
||
|
|
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.
|
||
|
|
.TP
|
||
|
|
.B off
|
||
|
|
Remove the current list of addresses and disable the spy functionality
