Hi all !

How to disable batgat ? It necessary recompiling batmand or is enough to
unload batgat module ?
I do that and batmand load but the gw never more assign ip trough the tunnel
iface....

TIA

Hello Gustavo,

batman works fine without the batgat kernel module. The batgat kernel
module will only accelerate the gateway functionality, but batman can do
without it. If you don't want it, don't insmod batgat. Batman will detect it
at runtime, no need to recompile.
The gateway should still work, if it doesn't then you probably found 
a bug.

best regards,
	Simon

Thanks for your answer.
I am experimenting very frustrating issues with batgat. Currently i am
testing the last trunk of kamikaze on ubiquity NS2. Batmand dies quietly
with batgat loaded. I will prove the last kamikaze on two NS2 without batgat
and inform the bug  if this error happen again.
Regards.
Gustavo.

I think it would be intersting to find out why batmand dies. May be you could 
produce a core dump ?
Indeed, we have a problem if the batman daemon dies without telling the 
module. What about adding a keep alive + timeout in the module ?

That does not look like a crash ?! Is your log related to the issue mentioned 
by the original reporter ? He said his batmand crashes and the kernel module 
is still alive.

To debug your issue a tcpdump on UDP port 4306 would help. So we can see what 
packages are sent forth and back.

It seems you are using an older version of the daemon together with the kernel 
module. "0.3-beta" may not be compatible with the latest kernel module.

It does not crash here but exits because it can't set the IP address. 

Please update to the latest versions first.

It is a bug "introduced" by linux v2.6.24-rc1-1-gbada339. I will send a patch 
after I've done some other stuff.
