[B.A.T.M.A.N.] Determining on which node a client is connected to

[Mitar]

Hi!

Is it possible to determine from central location (for example
gateway) to which node a client is currently connected to? So from
DHCP you can get MAC-IP translation, but how to get from MAC on which
node client currently is?

Read the translation table section:

Hello Mitar,
if I correctly got your question, you want to know what the Global Translation
Table of each node already contains.
Using "batctl tg" or directly inspecting the sysfs you will get such table with
all the client entries.

However, I didn't get why you need the node MAC.

I think there was some misunderstand. I would just like to know on
which node a client is connected to. And as I understand, this is
globally shared between all nodes so I can just inspect this on one
node through global translation table. But for client I begin with the
IP. So with DHCP, I can get client's MAC, and from there I look into
global translation table. This tells me where the client is.
