[Tutorial] Found Address IP of IAP #mhc

[ Edited ]

Hi,

 

Sometimes, it is no easy to found the IP address of IAP... (no closed IAP or no documentation about IP configuration...)

 

There is a easy method for found the IP Address of IAP.

 

You need a lasted build of Wireshark (> 1.11.3 available here, will be available in next major release 1.12 in may/june 2014).

 

Set a laptop in some network (vlan) like IAP and launch capture :

 

set aruba_iap display filter in Wireshark

ws_arubaiap_filter.png

 

And i will display the list of IAP will be broadcast in the network with the IP of IAP :

 

ws_arubaiap_ip.png

 

Now, launch your favorite browser and launch a connexion to the IP found by Wireshark ! :-)

The way I do it's: 

tcpdump -i <name for the interface you want to view traffic on> -n ether host <mac of the AP> and port 67 or port 68

 

I'm sure if you spend a little time you can find the correlation in WireShark.

@Constatin

 

Yes but i only with the IAP use DHCP (and on start of IAP)

My solution work with Fixed IP and no need restart of AP ;-)

Re: [Tutorial] Found Address IP of IAP #mhc

then you don't put the ports at the end and you see all the traffic comming from that MAC address thus you will see the IP too.

At the same time you could use arping -i <inteface name> <mac address> and the reply will come with IP
