Check Point V-80をいじり倒す

まだWIP

U-Bootなんもわからん

最終目標はDebianを入れてDockerを動かす

U-Boot sysbootを使えるようにする

Section titled “U-Boot sysbootを使えるようにする”

簡素な設定ファイルを使用してU-Bootからディストリビューションのカーネルなどを起動できる機能

本体の公式FWを起動してexpertシェルから設定を投入する。

USBメモリの/にextlinux.confがある想定だがパスを変えれば/bootとかに置いたものも認識する

run bootcmd_ow_usb; run bootcmd_ow_emmcはOpenWRT用の設定

OpenWRTインストール手順

# fw_setenv bootcmd_ow_sysboot 'usb start; sysboot usb 0:1 any ${loadaddr} /extlinux.conf;'
# fw_setenv bootcmd 'set cp_quiet; run set_bootargs_vx; run bootcmd_ow_sysboot; run bootcmd_ow_usb; run bootcmd_ow_emmc; run bootcmd_part${activePartition};'

extlinux.confのサンプル

Section titled “extlinux.confのサンプル”
  • ここで指定するファイルはmkimageで作ったuimageではなく生イメージでOK
  • kernelはgzip圧縮したもの（vmlinuz）はダメなので解凍する
label debian
    kernel /boot/vmlinux-6.6.51-mvebu-cortexa72
    initrd /boot/initrd.img-6.6.51-mvebu-cortexa72
    fdt /boot/armada-7040-v-80.dtb
    append console=ttyS0,115200 earlycon=uart8250,mmio32,0xf0512000 earlyprink root=/dev/sda2 rw rootwait mvpp2x.queue_mode=1 ethaddr=${ethaddr} eth1addr=${eth1addr} eth2addr=${eth2addr}  eth3addr=${eth3addr}

Debianのカーネル

Section titled “Debianのカーネル”

OpenWRTのカーネルを基にDebianで必要っぽい機能を有効化したもの

https://github.com/junk-labs/debian-mvebu_cortexa72/releases/tag/Releasefornow

DebianにおけるNICの認識順序

Section titled “DebianにおけるNICの認識順序”
  • lan1～lan5＝筐体の印字
  • eth0 DSAの根本(lan1~lan5の状態に応じて自動的に構成されるので触らない)
  • eth1 WANポート

ethtoolを使えば設定変更できるかも

auto lo
iface lo inet loopback


# WAN Port
allow-hotplug eth1
iface eth1 inet dhcp


# LAN PORT
allow-hotplug lan1
iface lan1 inet dhcp


allow-hotplug lan2
iface lan2 inet dhcp


allow-hotplug lan3
iface lan3 inet dhcp


allow-hotplug lan4
iface lan4 inet dhcp


allow-hotplug lan5
iface lan5 inet dhcp
