[SOLVED] Search through connected MAC addresses possible?

konradwalsh

Is something like this possible?

The idea is that known MAC addresses are queryable and I can trigger a http call to set a status bit

I have searching all day.. trying to find appropriate script commands to do something similar..

this is what works on DD-WRT

#!/bin/sh
# seconds between checks
WATCHDOG_SLEEP_SEC=2
# MAC Address 1
MAC_ADDRESS_1="[XX:XX:XX:XX:XX:XX]"
# MAC Address 2
MAC_ADDRESS_2="[YY:YY:YY:YY:YY:YY]"
# Vera VSwitch 1 Device ID
VSWITCH_1="[99]"
# Vera VSwitch 2 Device ID
VSWITCH_2="[100]"

#This loop will check if a device is registered on the AP and send the on/off command to vera. 

while sleep $WATCHDOG_SLEEP_SEC
do
if wl assoclist | grep -Fq $MAC_ADDRESS_1
then
    #echo Device 1 user is in
    wget -qs "http://[YOUR_VERA_IP_ADDRESS]:3480/data_request?id=lu_action&output_format=xml&DeviceNum=$VSWITCH_1&serviceId=urn:upnp-org:serviceId:VSwitch1&action=SetTarget&newTargetValue=1"
else
    #echo Device 1 user is out
    wget -qs "http://[YOUR_VERA_IP_ADDRESS]:3480/data_request?id=lu_action&output_format=xml&DeviceNum=$VSWITCH_1&serviceId=urn:upnp-org:serviceId:VSwitch1&action=SetTarget&newTargetValue=0"
fi

if wl assoclist | grep -Fq $MAC_ADDRESS_2
then
    wget -qs "http://[YOUR_VERA_IP_ADDRESS]:3480/data_request?id=lu_action&output_format=xml&DeviceNum=$VSWITCH_2&serviceId=urn:upnp-org:serviceId:VSwitch1&action=SetTarget&newTargetValue=1"
else
    wget -qs "http://[YOUR_VERA_IP_ADDRESS]:3480/data_request?id=lu_action&output_format=xml&DeviceNum=$VSWITCH_2&serviceId=urn:upnp-org:serviceId:VSwitch1&action=SetTarget&newTargetValue=0"
fi

done

Look at /usr/local/www/status_wireless.php, modify that above accordingly, run from cron.

Hi
thanks very much for looking at this..

I should add.. I am really trying to look up any device is connected.. not just wireless devices..

So far I am playing with things like arp lookup and also trying to see if I can vary this command to get what I want … ifconfig vtnet0 | grep ether

i thought I might get something back from this command
arp -na | grep -Fq e8:5a:8b:b6:71:5c

but my inexperience is showing

What's the problem with that? It works just fine - will return 0 on success, 1 on failure. You can see that with


arp -na  | grep -Fq aa:bb:cc:ff:ee:ff; echo  $?

arp -na | grep -Fq is exactly what you need for the script as far as wired clients are concerned.

yes you are right… i didn't test that command thoroughly enough..

thanks again
