OpenWRT on WR703N with shadowsocks

TP-Link WR703N only have 4M flash, so we have to remove all unnecessary package and rebuild OpenWRT.

Note 1: If you do not need wifi, remove all package in kernel/wireless drivers. and wifi related tools.
Note 2: WR703N usb only support USB2.0, without hub, you only need core+usb2, ohci and uhci is not needed.

OpenVPN on OpenWRT

需要注意的是在使用trunk 自己编译OpenWRT时,必须自己编译kmod-tun,不能使用repo的二进制文件 可能需要自己编译OpenVPN.

GoAgent on OpenWRT 解决崩溃问题

Follow官方WiKi进行安装

后发现打开ssl网站经常导致goagent崩溃,参考官方Issue
里面也提到了原因是libopenssl线程安全问题

参照
制作一个patch并重新编译替换libopenssl

OpenWRT for WR720N

OpenWRT already officially support WR720N!
Ref:
http://wiki.openwrt.org/toh/tp-link/tl-wr720n

准备工作


Linux磁盘空间大概要准备10G.

先从svn checkout出OpenWRT
svn checkout svn://svn.openwrt.org/openwrt/trunk openwrt

进去看一下

[[email protected] ~]$ cd openwrt/
[[email protected] openwrt]$ ls
BSDmakefile LICENSE README feeds.conf.default package scripts toolchain
Config.in Makefile docs include rules.mk target tools

好了.
