            编译内核和iptables及安装l7proto

一、环境介绍

操作系统:Redhat5.8_64bit

需要软件包:

linux-2.6.28.10.tar.gz

netfilter-layer7-v2.22.tar.gz

l7-protocols-2009-05-28.tar.gz

iptables-1.4.6.tar.bz2

安装步骤:

1)、给内核打补丁,并重新编译内核

2)、给iptables源码打补丁,并重新编译iptables

3)、安装l7proto


1、给内核打补丁并重新编译内核

[root@localhost ~]# uname -r   //Redhat5.8自带内核版本是2.6.18

2.6.18-308.el5

# tar zxvf  linux-2.6.28.10.tar.gz  -C  /usr/src   //解压linux-2.6.28

# tar zxvf netfilter-layer7-v2.22.tar.gz -C /usr/src  //解压netfilter-layer7

# cd /usr/src/

# ln -s linux-2.6.28 linux

# cd /usr/src/linux/

# patch -p1 < ../netfilter-layer7-v2.22/kernel-2.6.25-2.6.28-layer7-2.22.patch 

patching file net/netfilter/Kconfig

patching file net/netfilter/Makefile

patching file net/netfilter/xt_layer7.c

patching file net/netfilter/regexp/regexp.c

patching file net/netfilter/regexp/regexp.h

patching file net/netfilter/regexp/regmagic.h

patching file net/netfilter/regexp/regsub.c

patching file net/netfilter/nf_conntrack_core.c

patching file net/netfilter/nf_conntrack_standalone.c

patching file include/net/netfilter/nf_conntrack.h

patching file include/linux/netfilter/xt_layer7.h

# cp /boot/config-2.6.18-308.el5 /usr/src/linux/.config  

# make  menuconfig 

提示:make  menuconfig之前确保下面开发环境安装好了:

Development Libraries

Development Tools


执行:make menuconfig如下错误提示:

scripts/kconfig/mconf arch/x86/Kconfig

.config:1365:warning: symbol value ‘m‘ invalid for FIXED_PHY

.config:1671:warning: symbol value ‘m‘ invalid for ISDN

.config:2789:warning: symbol value ‘m‘ invalid for RTC_INTF_SYSFS

.config:2790:warning: symbol value ‘m‘ invalid for RTC_INTF_PROC

.config:2791:warning: symbol value ‘m‘ invalid for RTC_INTF_DEV

.config:2813:warning: symbol value ‘m‘ invalid for DMA_ENGINE

Your display is too small to run Menuconfig!

It must be at least 19 lines by 80 columns.

make[1]: *** [menuconfig] Error 1

make: *** [menuconfig] Error 2

原因:终端窗口大小了,导致的。

# screen  //防止make时候中断

# make

# make modules_install

# make install


2、编译新版本iptables

# cp /etc/init.d/iptables ~/iptables

# cp /etc/sysconfig/iptables-config ~/

# cp /etc/sysconfig/iptables ~/iptables.rules

# service iptables stop

# chkconfig iptables off

# rpm  -e  iptables-ipv6  iptables  iptstate  --nodeps

# tar jxvf iptables-1.4.6.tar.bz2 –C  /usr/src

# cd /usr/src/iptables-1.4.6

# cp ../netfilter-layer7-v2.22/iptables-1.4.3forward-for-kernel-2.6.20forward/libxt_layer7.*   ./extensions/

# ./configure  --prefix=/usr  --with-ksource=/usr/src/linux

# make

# make install

# which iptables

/usr/sbin/iptables

# vim ~/iptables  -->修改如下内容

if [ ! -x /usr/sbin/$IPTABLES ]; then

    echo -n $"/usr/sbin/$IPTABLES does not exist."; warning; echo

    exit 0

fi


# cp ~/iptables  /etc/init.d/

# chkconfig --add iptables

# cp ~/iptables-configs /etc/sysconfig/

# service iptables start

Applying iptables firewall rules:                          [  OK  ]

Loading additional iptables modules: ip_nat_ftp ip_conntrac[  OK  ]

3、安装l7-protocols

# tar zxvf l7-protocols-2009-05-28.tar.gz

# cd l7-protocols-2009-05-28

# make install

mkdir -p /etc/l7-protocols

cp -R * /etc/l7-protocols

# service iptables restart
