I have been stuck on this issue for two days now and couldnt find a fix for this. I installed a realtime kernel with
sudo apt-get install linux-rt
because KauNet (which is an ipfw extension) requires a real-time kernel for millisecond granularity.
However after trying to install KauNet I get this error message:
ERROR: Kernel configuration is invalid. include/linux/autoconf.h or include/config/auto.conf are missing Run 'make oldconfig && make prepare' on kernel src to fix it.
Both files are there.
auto.confcan be found in
autoconf.h is in
Before I installed
2.6.31-10-rt kernel i was on
2.6.32-21-generic and KauNet/ipfw was working.
I appreciate any help. Thanks.
