From: Simon Kirby <sim@netnation.com> Date: Thu, 10 Jul 2003 16:29:16 -0700 Hmm... Is this issue (ICMP packets being dropped due to lazy locking) supposed to be fixed in current 2.4 (2.4.22pre4, for example)? Yes, it is. I checked the code and the patch appears to be in there. I wonder what is causing the loss now... tcpdump on the machine being pinged shows it not responding to all of the ICMP it receives, as was happening before. Check if icmpv4_xrlim_allow() is returning zero ever, I bet it is. Setting sysctl_icmp_ratemask to zero would be a good test to eliminate this as a culprit. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
