Hey can any one help me I am using fedora core 2 installation Now I want to work on traffic control using layer7 filter So for that I need to patch iptables I am new to linux But in my installation I cant find source code for iptables.. I am confused where to patch itâ bcoz I cant find that directory â I can see the iptables as an executable file in /sbin directoryâ is it the location to patch??????? I did so but it didn't work out Then when I downloaded a new iptables files from netfilter.org and placed in /usr/src/linux and when I executed the commands as given in a documentation page Next up we will compile the IPtables package. To do so, enter in the following commands from the IPtables directory. make pending-patches KERNEL_DIR=/usr/src/linux make KERNEL_DIR=/usr/src/linux make install KERNEL_DIR=/usr/src/linux it shows the following error /usr/src/linux/include/linux/config.h:6:2: #error including kernel header in userspace; use the glibc headers instead. What does it mean? How exactly to patch iptables and where I can find iptables directory in my installation Help greatly appreciated ; Looking for rescue sujith -- sujith chandra chowdhary CHENNUPATI
