开发环境搭建示图

1) 请将SE3、笔记本电脑组一个局域网

2) 配置SE3 IP static address

** 更改 interfaces 文件，address即可 **
# sudo vim /etc/network/interfaces.d/eth0
auto eth0
iface eth0 inet static
        address 192.168.1.185
        netmask 255.255.255.0
        gateway 192.168.1.1
        dns-nameservers 192.168.1.1
# 退出保存文件
sudo ip addr flush eth0
sudo systemctl restart networking.service
# reboot系统后，ip地址变成192.168.1.185
# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.1.185  netmask 255.255.255.0  broadcast 192.168.1.255
        inet6 fe80::9c25:81ff:fe76:adf0  prefixlen 64  scopeid 0x20<link>

        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>
        loop  txqueuelen 1  (Local Loopback)

3) 路由器连接Internet， 下图是TP-LINK的配置方式
