Hi i want to apply the patch ftos in order to change the tos field in ip packets... The problem is that i don't know how to do that One guy suggest me the http://www.paksecured.com/patches/ but the patch is for the 2.4 kernel but i use the 2.6.10 kernel. In addition to this i have noticed that the 2.6 kernel has the following option CONFIG_IP_NF_MATCH_TOS I don't know if i need to compile it as module or i should insert them directly to the kernel... Afte recompiling the kernel i have run the make KERNEL_DIR=/usr/src/linux-2.6.10 but still the command iptables -t mangle -A PREROUTING -i eth0 -p tcp --dport 22 -j TOS --set-tos 15 iptables v1.2.11: Bad TOS Value Any suggestion? __________________________________ Do you Yahoo!?
