Linux通过手机上网

1.安装相关软件
sudo apt-get install wvdial

2.得到GPRS的IP地址
(1)
手机调整到usb lan模式，在手机打开一个网页，让它的GPRS连通
(2)
运行 sudo /sbin/ifconfig
确认usb0存在
(3)
运行 sudo /sbin/ifconfig usb0 192.168.1.1
配置电脑上的usb0的IP为192.168.1.1
(4)
运行 telnet 192.168.1.2
telnet到手机，其中192.168.1.2为手机usb lan的IP，如下

$ telnet 192.168.1.2
Trying 192.168.1.2...
Connected to 192.168.1.2.
Escape character is '^]'.

由(4)得到gprsv2的IP为10.10.88.48，记录下来

3.为pppd添加GPRS IP
(1)
运行 sudo gedit /etc/ppp/options
在options文件的最后一行添加如下两行内容
novj
:10.10.88.48
其中10.10.88.48为2.(5)所得到的GPRS IP地址

4.配置/etc/wvdial.conf并连接上网
(1)
关掉手机的网页，确认手机上的GPRS连接已经断开
(2)
手机调整到usb modem模式
(3)
运行 wvdialconf
检测手机的modem连接是否正常，程序自动创建/etc/wvdial.conf文件，正确情况如下

$ wvdialconf
Editing `/etc/wvdial.conf'.

$

(4)
运行 sudo gedit /etc/wvdial.conf
修改其内容，Baud保持4.(3)中程序自动创建的值，Username和Password的值到手机的网络设置查看
本例使用CMNET连接，文件内容如下

[Dialer Defaults]
Init1 = ATZ
Init2 = AT&FE0V1&C1S0=0
Init3 = AT+cgdcont=1,"IP","CMNET","",0,0
Modem Type = USB Modem
ISDN = 0
Phone = *99***2#
New PPPD = yes
Modem = /dev/ttyACM0
Username = 172
Password = 172
Baud = 460800
Idle Seconds = 3000
Auto DNS = 1
Stupid Mode = 1
Dial Command = ATD
Ask Password = 0
FlowControl = NOFLOW

(5)
禁用eth0等网络联连接
另：如果是在Debian Gnome环境下，右上角的网络连接工具，“启用联网”一项反选

(6)
运行 sudo wvdial
让Linux通过手机上网，正常情况如下

$ sudo wvdial
--> WvDial: Internet dialer version 1.60
--> Cannot get information for serial port.
--> Initializing modem.
--> Sending: ATZ

收到local IP address说明网络连接成功，终端里按Ctrl+C终止网络连接
