The hidden diff is vetoed by the TCP/IP people. There also is a better method available in the AS and 7.3 kernels by means of netfilter-for-arp. netfilter as well as useing "ARP=no" in the ifcfg-lo:0 seem to not be effective in this type of case. The loopback addresses seem to still respond to broadcast ARP requests. The hidden patch was the only thing found that resolved the problem. 2.4.18 (and the Advanced Server kernel) add a special netfilter-for-arp-packets mode, THAT is what I meant Our production enviroment runs on Redhat linux 7.2 currently running the 2.4.9- 37 kernel. I can't seem to be able to find any feature that has been able to successfully hide the loopback address from broadcast ARP requests. Disableing proxy_ARP does not solve the problem either. It seems all the news group mention your suggestion but then that gets shot down as it does not solve the problem. If you are able to successfully hide the loopback addresses from answering a broadcast ARP address in your testing on the RedHat provided 2.4.9-37 kernel for redhat 7.2 without the hidden patch please let the world know as anyone in a HA/load balanced solution is being forced to create custom kernels right now. Thanks for the bug report. However, Red Hat no longer maintains this version of the product. Please upgrade to the latest version and open a new bug if the problem persists. The Fedora Legacy project (http://fedoralegacy.org/) maintains some older releases, and if you believe this bug is interesting to them, please report the problem in the bug tracker at: http://bugzilla.fedora.us/ |
