Hi, I'm not sure if you can ignore ICMP requests, but I have been able to modify icmp.c to stop the kernal replying to ping requests. This halves the amount of traffic if you are flood pinged, plus the person pinging you, may well believe that you are down because of the absence of replies. I added this to icmp.c in the /usr/src/linux/net/ipv4 directory, and then re-compiled. Seems to work okay on 2.0.28. #define CONFIG_IP_IGNORE_ECHO_REQUESTS Regards, Don |
