It is very likely that the traffic that you are seeing is broadcast
traffic. I believe that cable modem systems are multiaccess networks,
unlike DSL which is usually a point to point connection. So, things
like arp requests will be seen by all hosts that are connected to the
same subnet. Not only are they multiaccess, but if the cable modem does
not keep track of mac addresses, and acts as a hub, and not a switch,
or better yet, a router, then you will also see all other traffic from
your neighbors. I have DSL, so I am not to hip on the cable modem
scene, but prefer DSL over cable.

Yes, the data light is blinking away, about the same time as the

The cable modem is a Terayon TJ120, if that helps any.

One of the members of the Airport engineering team, indicated that
he's seen the continuous light activity when attached to a cable
modem connection.
I wonder whether you see any network activity on the Ethernet portion
of the connection?
As for the extra features to the Airport Base Station, this has been
logged as an enhancement request and the team is investigating them.

I have also wondered if maybe my ISP is ping-ing the base station,
to see if
they can use the IP address maybe ???, but seems quite continuous.
I agree about the extra feature(s) to airport base station, as there
is no
reporting stats for it, which is a major hole in my books, compared
to other
hubs. Hopefully we'll have it soon ??? (I hope Apple is listening
:-) ), I
have a couple of months ago asked for better reporting features,
cannot
remember the radar bug number.

I have not snmpwalk'd my airport, but it is possible that the
airport
would allow you to dump the cam tables and give you the mac
addresses
that you know about. It would be trivial to then make a program
that
would tell you the number of users connected to your airport, and
their
mac address. I would like apple to add this into the base station
admin
program. We use the lucent ap-2000's at work (we have about 800
access
points), and their (windows only) software will tell you the
names, mac
addrs, s/n ratio of all the clients connected to the access point,
as
well as the time they have been connected and the number of bytes
they
have transmitted and received.
If you want to make sure that your airport is not being hacked
into, I
would recommend making it a closed network, with WEP, and using
the MAC
address access lists to explicitly list which airport cards can
associate with the airport. That would be fairly secure against
leeches

Hi,
I was wondering if there a way to get any status information on
exactly
the airport base station is doing, as I am wondering if my
airport base
station has been hacked into, wirelessly.
I have my air port base station attached to my cable modem
directly,
as my
cable modem needs to lock on the Ethernet address to work.
What's happening, is usually during the late evening I notice that
my
base
station left light is blinking quite a lot, and the data light on
the
cable
modem is blinking too, like while I am sending data down, but all
my
computers are off, so I know its not me.
I have setup, so all my Ethernet address are locked in to the base
station,
but this doesn't make any differences. Also the phone line isn't
attached so
there no dial-in going on.
I was wondering if I can tell what the base station is doing, and
maybe what
IP address is allocated to what Ethernet address. Is there anyway
to
log
what the thing is doing ????.
I know in previous airport base stations software, there was a
util to
monitor the signal strength, but this isn't there anymore.
Any Ideas anyone ???
Thanks
Mark.
