dear list i have notice that length.so and length6.so isn't compiled, linked and copied into the lib/ directory it works if i cc -O2 -Wall -Wunused -I/usr/src/linux/include -Iinclude/ -DNETFILTER_VERSION=\"1.2.6\" -fPIC -o extensions/libipt_length.o -c extensions/libipt_length.c
ld -shared -o extensions/libipt_length.so extensions/libipt_length.o cp extensions/libipt_length.so /usr/local/lib/iptables/libipt_length.so from the userspace directory and the same with length6 i used cvs update some times over the last month but i havent seen any changes Thanks Mikkel Kristensen
