What is NEMO & NEPL?

• NEMO - Network Mobility
• NEPL - NEMO Platform for Linux

OS - Debian GNU/Linux 3.1

Ref:

• mobile-ipv6.org
• NEPL (NEMO Platform for Linux) HOWTO
• Debian-Kernel-Compile-Howto (Kernel 2.6)
• Kernel Rebuild Guide

下载所需的软件包：

# cd /usr/src/
# wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.15.tar.bz2
# wget http://www.mobile-ipv6.org/software/download/nemo-0.2-linux-2.6.15.patch.gz
# wget http://www.mobile-ipv6.org/software/download/nemo-0.2.tar.gz

安装编译内核需要的工具：

# apt-get install kernel-package ncurses-dev fakeroot wget bzip2
# apt-get install module-init-tools initrd-tools procps
# apt-get install autoconf automake1.8 byacc flex libssl-dev indent

解压缩：

# tar jxf linux-2.6.15.tar.bz2
# gunzip nemo-0.2-linux-2.6.15.patch.gz
# tar zxf nemo-0.2.tar.gz

打上Mobile IPv6的patch：

# mv nemo-0.2-linux-2.6.15.patch linux-2.6.15/
# cd linux-2.6.15/
# patch -p1 < nemo-0.2-linux-2.6.15.patch

配置内核参数，加上Mobile IPv6支持：

# make menuconfig

在下列选项前打*号，都在Networking->Networking options下面

• PF_KEY sockets
  • PF_KEY migration interface (EXPERIMENTAL)
• The IPv6 protocol
  • IPv6: Privacy Extensions (RFC 3041) support
  • IPv6: AH transformation
  • IPv6: ESP transformation
  • IPv6: IPComp transformation
  • IPv6: IPv6-in-IPv6 tunnel
  • IPv6: advanced router (EXPERIMENTAL)
    • IPv6: policy routing
    • IPv6: source address based routing
  • IPv6: Mobility (EXPERIMENTAL)
    • IPv6: Moblity Debug Message

用NEPL包里带的chkconf_kernel.sh脚本检查内核配置：

# /usr/src/nemo-0.2/chkconf_kernel.sh /usr/src/linux-2.6.15/

Checking kernel configuration...
Using /usr/src/linux-2.6.15/.config
All kernel options are as they should.

如果看不到任何warning，就可以编译内核了。

# make bzImage
# make modules
# make modules_install
# mkinitrd -o /boot/initrd-2.6.15.img 2.6.15

安装新内核：

# cp arch/i386/boot/bzImage /boot/bzImage-2.6.15
# cp System.map /boot/System.map-2.6.15
# ln -s /boot/System.map-2.6.15 /boot/System.map

配置LILO：
image=/boot/bzImage-2.6.15 label=NEPL read-only initrd=/boot/initrd-2.6.15.img

使lilo生效

# lilo -v -v -v

用新的内核boot后，编译nemo：

# uname -a
Linux nepl-demo 2.6.15 #1 Tue Mar 14 15:14:49 CST 2006 i686 GNU/Linux # cd /usr/src/nemo-0.2/
# CPPFLAGS='-isystem /usr/src/linux-2.6.15/include/' ./configure --enable-vt
# make
#make install

可以制作一个内核的deb安装包：

# cd /usr/src/linux-2.6.15
# make-kpkg clean
# fakeroot make-kpkg --revision=nemo.0.2 kernel_image

制作好文件可以在/usr/src下找到 kernel-image-2.6.15_nemo.0.2_i386.deb
