破解完光猫不过隐,继续琢磨，查了些智能设备安全的教程，分析智能设备或嵌入式设备安全，第一步是要提取固件，所以接下来要提取固件了。

通过/proc虚拟文件系统读取MTD分区表：

/ # cat /proc/mtd
dev:    size   erasesize  name
mtd0: 08000000 00020000 "whole flash"
mtd1: 00200000 00020000 "u-boot"

Mounting JFFS2 Images on a Linux PC

It is possible to mount a binary JFFS2 image on a Linux PC without a flash device. This can be useful for examining the contents of the image, making required changes, and creating a new image in any format. When a JFFS2 image is copied directly from a JFFS2 flash partition, the resulting image is the size of the source partition, regardless of how much space is actually used for storage. Mounting the filesystem and using the mkfs.jffs2 utility to create a new image will result in a JFFS2 image without blank nodes. This can also be used to create multiple images for flashes with different characteristics, such as erase block sizes. This page describes two different methods of mounting JFFS2 images on a Linux PC.

This procedure requires that the following kernel modules are available or built-in to the kernel on the development machine: mtdram, mtdblock, jffs2, block2mtd, and loop.
