[Bridge] ULOG The kernel doesn't support a certain ebtables extension, consider recompiling your kernel or insmod the extension.

[Thomas Berg <thomas.berg@branndal.se>]

Hi,

Running debian unstable with kernel Linux version 2.6.30-1-686 (Debian 
2.6.30-6)
trying to use ulogd and dont get it to work I get a strange error that I 
cant figure out how to workaround, except recompling the kernel, but the 
kernel is already complied with bridge support, is there any other 
support that i should include?

/sbin/ebtables --modprobe /sbin/modprobe -A FORWARD --in-interface 
eth1.4 --protocol IPv4 --ip-protocol udp --ip-destination-port 67 -j 
DROP --ulog

Isnt ebtables supposed to auto load its needed modules? I was planning 
to log dhcp-req and desp-answ packets to a file for further handling 
with ulogd.
