[B.A.T.M.A.N.] Want to count the number of nodes connecting to a batman gateway

[david johnson]

Hi

I'm busy trying to adapt batman-exp to do some fair bandwidth allocation
and to do this I need each tunnel from a client to be shown as a
seperate vpn.  Or I need a way to count the number of nodes connecting
to the gateway

Do you know how I could  do this?

David

The batgat kernel module has that feature exposed via /proc but I have no idea 
what bmx can do for you.

Hi,

Currently this information is not provided by bmx. 
In two-way-tunnel mode this information is knwon by the daemon but not 
accessible with any debug output. I've also casually recognized the need for 
this information (including timeout and last request timestamps) in order to 
better understand and debug various gw scenarios.  So for the two-way-tunnel 
its not a big issue, I have it on my todo list. 
But for one-way-tunnel it would mean additional overhead and introducing some 
stateful functions&datastructures into a currently stateless gw mechanism.

Theoretically, the connected gw-clients could be identified by the different 
source addresses passing the bat0 interface of the gateway node (using 
tcpdump, iptables,...).  But honestly, I am not aware of any elegant way to 
catch these addresses.

ciao,
axel
