A new stable kernel has been released (2.0.24). This fixes the ping problem, and it's a good idea to upgrade to that, rather than applying any patches you find here


Patches for Linux prevent the Ping Problem

The following are three patches which can be applied against Linux to prevent the Invalid Ping problem. Either patch is to be applied against linux/net/ipv4/ip_fragment.c, and should apply cleanly against any 2.0.x or 2.1.x series kernel. Thanks to both of these two, especially Alan, for fixing this so quickly.
