重新编译
iptables
一.重新编译后的内核版本为:
2.6.28
.10
重新编译后的
iptables
的版本为:
1.4.4
,新添加了
layer7
的模块,使
iptables
可以工作在应用层
二.编译时需要用到的四个软件包为:
linux- 2.6.28 .10.tar.gz
netfilter-layer7-v2.22.tar.gz
iptables- 1.4.4 .tar.bz2
l7-protocols- 2009-05-28 .tar.gz
三.步骤:
1.
tar zxvf linux- 2.6.28 .10.tar.gz -C /usr/src
2.
tar zxvf netfilter-layer7-v2.22.tar.gz -C /usr/src
3.
ln �Cs /usr/src/linux- 2.6.28 .10/ /usr/src/linux
4.
cd /usr/src/linux/
5.
patch -p1 < ../netfilter-layer7-v2.22/kernel- 2.6.25 -2.6.28-layer7-2.22.patch
6.
cp /boot/config- 2.6.18 -164.el5 /usr/src/linux/.config
7.
make menuconfig
(在
make menuconfig
之前,要确认你的gcc
开发工具装上)

10.
make
11.make modules_install
12.make install
然后编辑
/boot/grub/grub.conf
文件,设置
default
的值为
0
,然后重新启动计算机
13.
cp /etc/rc.d/init.d/iptables ~/iptables
14.
rpm -e iptables-ipv6 iptables iptstate --nodeps
15.
tar jxvf iptables- 1.4.4 .tar.bz2 �CC /usr/src
16.cd /usr/src/iptables- 1.4.4
17.cp ../netfilter-layer7-v2.22/iptables- 1.4.3 forward-for-kernel-2.6.20forward/libxt_layer7.* ./extensions/
18.
./configure --prefix=/usr --with-ksource=/usr/src/linux
19.make
20.make install
21.tar zxvf l7-protocols- 2009-05-28 .tar.gz
22.
cd l7-protocols- 2009-05-28
23.make install
24.
mv ~/iptables /etc/rc.d/init.d/
25.ln �Csv /usr/sbin/iptables /sbin/iptables
25.service iptables start
然后就可以利用重新编译后的
iptables
做应用层的设置,以此达到希望的效果。
