Re: ULOG The kernel doesn't support a certain ebtables extension, consider recompiling your kernel or insmod the extension.

Hi

trying this

rmmod ipt_ulog

modprobe ebt_ulog

ebtables 14108 3 ebtable_broute,ebtable_nat,ebtable_filter
x_tables 14108 5 ebt_ulog,ebt_nflog,ebt_ip,ebt_log,ebtables


module is then loaded, great but still the same error when trying to add 
a ebtables rule with ulog.

br0:~# /sbin/ebtables --modprobe /sbin/modprobe -A FORWARD 
--in-interface eth1.4 --protocol IPv4 --ip-protocol udp 
--ip-destination-port 67 -j DROP --ulog
The kernel doesn't support a certain ebtables extension, consider 
recompiling your kernel or insmod the extension.

unloading ebt_ulog and then trying to add a rule with ulog ends up with 
ebt_ulog loaded but still getting the same error message

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

So ebtables is loading ebt_ulog if ipt_ulog is unloaded but still there 
is this error message that the kernel need to be recompiled or try to 
load module.

I´ll have to check out nfnetlink_log and se if I can use that instead, 
is it forwaring the whole packet to userspace?

Best regards,
Thomas
