ubuntu-16.04.5-desktop-amd64.iso
淘宝购买机器：研凌工控

安装之后，执行如下命令:
安装 ssh server服务：
sudo apt-get install openssh-server

为root 账户 设置密码：
sudo passwd root

安装4G 拨号软件:
apt-get install wvdial
apt-get install usb-modeswitch

使用 移动 4G卡:
sudo vi /etc/wvdial.conf

[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0
Init3 = AT+CGDCONT=1,"IP","3gnet"
Modem Type = Analog Modem
Baud = 9600
New PPPD = yes
Modem = /dev/ttyUSB0
ISDN = 0
Phone = *99#
Password = guest
Username = guest
Auto Reconnect = on
Auto DNS = on

启动的时候，delete键 进入BIOS
然后 设置Chipset -->OS Selection 设置为windows 8.x
只有安装windows7的时候，才能选择windows 7
其他的时候都选择 windows 8.x

拨号测试
输入下述命令测试ME909s模块拨号情况，拨号成功则证明手机卡可以借助ME909s模块使用。

sudo wvdial hw1
1
若配置wvdial.conf文件时没有修改文件名，即wvdial.conf文件开头

[Dialer Default]
1
则拨号测试命令为

sudo wvdial
1
输入该命令后需要等待一段时间，一般30s左右，如果没有错误信息或停止，一直等下去

若出现名字为ppp0的网卡设备，并且已经获得IP地址，证明ME909s模块初始化成功，是WIFI或有线网的影响导致，则修改路由表：
2.2.查看路由表

route -n
1
信息可能如下：

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 eth0
10.64.64.64 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.1.0 0.0.0.0 255.255.255.0 U 202 0 0 eth0
1
2
3
4
5
可以看出访问未知目标时，使用的是eth0的网卡，此处我们将其修改为使用ppp0来访问未知目标：
2.3.删除eth0的第一条路由信息：

sudo route del –net 0.0.0.0 eth0
1
新增一条ppp0的路由信息：

sudo route add –net 0.0.0.0 ppp0
1
修改后路由信息为：

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0
10.64.64.64 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0

192.168.1.0 0.0.0.0 255.255.255.0 U 202 0 0 eth0

此时再次尝试ping外网。
