maix2 dock设置静态ip(v831)

前言

V831内置了udhcpc获取动态ip,在使用ssh及其他服务时ip变动会很麻烦,遂打算使用静态ip。

开始

  1. 备份文件
cd /etc/init.d
cp rc.final rc.final.back
chmod -x rc.final.back
  1. 添加静态ip
echo  -e ifconfig wlan0 192.168.137.123 netmask 255.255.255.0\\nroute add default gw 192.168.137.1  >>/etc/init.d/rc.final

193.168.137.123为打算使用的静态ip,
255.255.255.0为掩码,
192.168.137.1为网关,具体以实际为准。
3. 测试

reboot
ifconfig
ping www.baidu.com

输出如下:

测试ssh连接

To escape to local shell, press 'Ctrl+Alt+]'.

sh: /usr/bin/xauth: not found

结尾

以上方法并没有关闭udhcpc程序,开机还会自行获取ip,如果需要关闭,
vim /etc/init.d/S40network,注释掉udhcpc -iwlan0 -b, 如下:

  start)                                                                               
        echo "Starting network..."                                                     
        do_insmod                                                                      
        sleep 1                                                                        
        /sbin/ifconfig wlan0 up                                                        
        sleep 1                                                                        
        wpa_supplicant -c /etc/wpa_supplicant.conf -iwlan0 -B                          
        #udhcpc -iwlan0 -b  

实际上,在这里添加ifconfig命令应该也执行的,但是实际测试时会提示
route: SIOCADDRT: Network unreachable,还未找到原因。
另外,编辑/etc/profile文件也可以,但是会导致每次ssh都执行一遍,因此不建议用。
