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

make编译之后直接安装新的bin/ar71xx/packages/libopenssl_1.0.1c-1_ar71xx.ipk即可

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.

修改源文件
