Bug 20698 – Hidden ARP patch for Gentoo-sources

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Brett Simpson 2003-05-09 08:40:45 UTC]

Could the Julian Anastasov Hidden-Arp patch be included in the Gentoo kernel? This patch 
(as described in http://www.ssi.bg/~ja/hidden.txt) allows a web server to be used in an 
LVS (Linux Virtual Server) direct route. Once the patch is applied it is not active unless the 
following is done. 
 
# Enable the functionality 
echo 1 > /proc/sys/net/ipv4/conf/all/hidden 
 
# Hide all addresses on this interface 
echo 1 > /proc/sys/net/ipv4/conf/<interface_name>/hidden 
 
This is the web page that has the patches. 
http://www.ssi.bg/~ja/ 
 
Also I applied the hidden-2.4.19pre5-1.diff to the 2.4.19-gentoo-r10 kernel to two 
production Redhat web servers. This has been in place for over 7 months and has been 
stable.  
 
Thanks, 
Brett

Cool! I'm looking to convert two existing Redhat 7.3 servers running coldfusion to 
Gentoo. Both of them are part of an LVS direct route setup that use the hidden arp 
stuff. I could patch it myself put I wanted to minimize the work on setting up 
additional systems for the other admins here.
