jslinux-network

git clone https://github.com/killinux/jslinux-network

把 jslinux-network 放在apache或者nginx中。

yum install python-virtualenv

virtualenv mysite

source mysite/bin/activate

pip install mod_pywebsocket

cd jslinux-network/websocketstuntap

这里需要tap_wsh.py

python -m mod_pywebsocket.standalone -d . --log-level=info -p 3000

或launch.sh

这时，ifconfig

假设本机IP是192.168.139.85
vim network-websockets.js
第7行改成

tuntapWS_connection = new WebSocket('ws://192.168.139.85:3000/tap', []);

chrome：
http://192.168.137.85/jslinux-network

先点boot
启动后，点connect or reconnect websockets启动websocket
chrome变黄色

这时观察后台launch.sh会建立个链接一个连接

(mysite)[root@centos32 websocketstuntap]# ./launch.sh

tuntapdevice: websockettuntap

ifconfig观察服务器会多个tap设备

        inet 10.0.2.1  netmask 255.0.0.0  broadcast 10.255.255.255

[root@centos32 linuxstart-20120111]# 

默认IP是10.0.2.1

进入jslinux后
cat /dev/clipboard|sh
生成tap设备

默认的ip是10.0.2.2
ping 10.0.2.1
能ping通表示正常


如果是自己编译的内核
需要注意.config文件一定要多一条
# CONFIG_EQUALIZER is not set
CONFIG_TUN=y

否则jslinux在建立tap设备的时候会说找不到设备的问题
