OpenWRT And User Mode Linux (UML)
Table of Contents
Get and compile OpenWrt
Compile yourself the OpenWrt with UML support.
Binaries
It is easier to download the UML binaries (the OpenWrt do not provide them on their downloads.openwrt.org website):
openwrt-uml-vmlinux (3MB) and openwrt-uml-ext2.img.bz2 (1.28MB)
Usage
Step 1: Download the 2 files
Download the 2 files in the same folder (let's say /tmp/openwrtuml/):
zoobab@gierek /tmp/openwrtuml [135]$ wget http://zoobab.wikidot.com/local--files/openwrt-and-user-mode-linux/openwrt-uml-vmlinux http://zoobab.wikidot.com/local--files/openwrt-and-user-mode-linux/openwrt-uml-ext2.img.bz2
