IP Virtual Server Netfilter module - Version 0.8.2 - October 23, 2001

This is free software.  See below for details.

The IPVS is IP Virtual Server support in Linux kernel, which can be
used to build a high-performance and highly available server. Check
out the Linux Virtual Server Project homepage on the World Wide Web:
	http://www.linuxvirtualserver.org/
	or
	http://www.linux-vs.org/
for the most recent information and original sources about IPVS.

The IPVS Netfilter module is for kernel 2.4, most of code are ported
from the IPVS patch (Version 0.9.13) for kernel 2.2. See the ChangeLog
for how the code has been improved and what new features it has now.

Some simple instructions to compile the IPVS Netfilter module (Version
0.8.2) on kernel 2.4.4 or later. First, apply the ksyms diff file
to the kernel souce.
        cd /usr/src/linux
        cat <path-name>/linux_kernel_ksyms_c.diff | patch -p1 
Then, rebuild a Linux kernel with Netfilter support.

To build and insert the ipvs modules, the commands can be as follows:
	# build the modules
	cd <path-name>/ipvs
	make
	make -C ipvsadm

	# insmod the modules and install ipvsadm
	su
	make install
	insmod ip_vs_wlc.o
	
	# set the debugging level
	echo 2 > /proc/sys/net/ipv4/vs/debug_level
	
	# ipvs configuration is like that of kernel 2.2

	# remove modules
	ipvsadm -C
	rmmod ip_vs_wlc
	rmmod ip_vs

	# list connections in the kernel
	ipvsadm -Lcn

To build the ipvs within the kernel, you need do the following commands:
	cd /usr/src/linux
        cat <path-name>/linux_kernel_ksyms_c.diff | patch -p1
	cat <path-name>/linux_net_Makefile.diff | patch -p1
	cat <path-name>/linux_net_ipv4_Config_in.diff | patch -p1
	cat <path-name>/linux_ip_fw_compat_c.diff | patch -p1
	cp -rp <path-name>/ipvs net/ipv4
	mv net/ipv4/ipvs/linux_net_ipv4_ipvs_Makefile net/ipv4/ipvs/Makefile 
	make menuconfig
	...

Or, you can download the single kernel ipvs patch from 
	http://www.linux-vs.org/software/index.html
and apply it to the kernel.
