I would like to have the l7-filter funtionality on my redhat el4. So I downloada the latest iptable-1.3.3 and the last patch from l7-filter But trying to compile the patched files I get this error: #error including kernel header in userspace; use the glibc headers instead! make: *** [extensions/libipt_layer7_sh.o] Error 1 I found several posts about it without any useful solution. In fact if I use "KERNEL_DIR=/usr" I get the header from userspace so everything is compiled but not the layer7 module "libipt_layer7.so". I checked if everything into the kernel (about packet filtering and layer7) is activated, and there, everythings seems fine. Just to note that "libipt_layer7.h" is not present on my system. Where is my problem? Thanks Rosario
