支持netfilter/iptalbes(can't initialize iptables table `filter': iptables who)

分类： 嵌入式

原文地址：http://blog.csdn.net/white_eyes/article/details/8191047

Android模拟器默认内核不支持netfilter，所以试图使用iptalbes时，会出现错误。


  1. # iptables -L
  2. iptables -L
  3. iptables v1.3.7: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
  4. Perhaps iptables or your kernel needs to be upgraded.
  5. # 
# iptables -L
iptables -L
iptables v1.3.7: can't initialize iptables table `filter': iptables who? (do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
#

解决方法是重新编译一个android内核，编译的时候打开netfilter相关模块，用新内核替换原有内核即可。



实验环境：ubuntu10.04 64bit



下载适用模拟器的android内核代码

查看可用版本



  1. root@ubuntu:~/android/kernel/goldfish# git branch -a
  2. * master
  3. remotes/origin/HEAD -> origin/master
  4. remotes/origin/android-goldfish-2.6.29
  5. remotes/origin/android-goldfish-3.4

下载2.6.29版本。



  1. root@ubuntu:~/android/kernel/goldfish# git checkout remotes/origin/android-goldfish-2.6.29
  2. Checking out files: 100% (26821/26821), done.

下载完成后，设置编译所需环境变量。



  1. root@ubuntu:~/android/kernel/goldfish# export ARCH=arm
  2. root@ubuntu:~/android/kernel/goldfish# export SUBARCH=arm
  3. root@ubuntu:~/android/kernel/goldfish# export CROSS_COMPILE=arm-eabi-
  4. root@ubuntu:~/android/kernel/goldfish# export PATH=/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:$PATH 
root@ubuntu:~/android/kernel/goldfish# export ARCH=arm
root@ubuntu:~/android/kernel/goldfish# export SUBARCH=arm
root@ubuntu:~/android/kernel/goldfish# export CROSS_COMPILE=arm-eabi-
root@ubuntu:~/android/kernel/goldfish# export PATH=/prebuilt/linux-x86/toolchain/arm-eabi-4.4.3/bin:$PATH

运行make


  1. make goldfish_defconfig 
make goldfish_defconfig

接下来配置编译的模块，这个过程可能会报缺少一些必要的包，可以提前安装相关的包，也可以根据错误逐步添加。


  1. root@ubuntu:~/android/kernel/goldfish# apt-get install ia32-libs 
root@ubuntu:~/android/kernel/goldfish# apt-get install ia32-libs

下面是实验过程记录。



  1. root@ubuntu:~/android/kernel/goldfish# make menuconfig
  2. *** Unable to find the ncurses libraries or the
  3. *** required header files.
  4. *** 'make menuconfig' requires the ncurses libraries.
  5. ***
  6. *** Install ncurses (ncurses-devel) and try again.
  7. ***
  8. make[1]: *** [scripts/kconfig/dochecklxdialog] Error 1
  9. make: *** [menuconfig] Error 2
  12. root@ubuntu:~/android/kernel/goldfish# apt-get install libncurses-dev

root@ubuntu:~/android/kernel/goldfish# apt-get install libncurses-dev

再运行make menuconfig，选择相关模块。


配置完成后，进行编译
