ubuntu 下 3G拨号

时间:12-04-13 栏目:技术 作者:liva 评论:0 点击: 19,531 次


   统:Ubuntu 10.04

         3G模块:华为E1750

1 安装usb-modeswitch软件

       E1750 无线上网卡并没有提供linux环境下的驱动程序,但我们可以通过USB模式转换来让linux系统能识别并能使用E1750无线模块。USB_ModeSwitch是一个用来控制“flip flop”(多重设备)USB装置的USB模块转换工具,USB_ModeSwitch 从配置文件中读取重要的参数并实现所有初始化以及通讯,其中还需要来自"libusb"的重量级支持。具体信息可参看网页:http://www.draisberghof.de/usb_modeswitch/

      

在网页http://www.draisberghof.de/usb_modeswitch/上下载USB模式转换的软件安装包:

usb-modeswitch-1.1.7.tar.bz2   

usb-modeswitch-data-20110227.tar.bz2   //可以不用

libusb-dev  //可不用下载,直接使用apt-get命令来安装

1>安装libusb-dev库文件

$ sudo apt-get install libusb-dev

2>安装usb-modeswitch-data

$tar jxvf usb-modeswitch-data-20110227.tar.bz2

$cd usb-modeswitch-data-20110227

$ sudo make install //将会在etc/usb_modeswitch.d安装一个配置文件,并且在/lib/udev/rules.d中安装udev规则文件

3>安装usb-modeswitch

$ tar jxvf usb-modeswitch-1.1.7.tar.bz2

$ cd usb-modeswitch-1.1.7

$ sudo make install  //此时将会在udev中安装一个shell脚本,一个大包装脚本,一个配置文件,man手册和新的二进制编译文件usb_modeswitch

使用usb-modeswitch调试一个未知的新设备,有两种方式进行调试:

u  使用配置文件

       使用配置文件,需要编写一个与自己硬件相关的配置文件,可参看usb-modeswitch-1.1.7下的device_reference.txt文件中,查找与自己硬件相关的部分,用做配置信息。如对于E1750无线网卡,在device_reference.txt文件中可查找到如下内容:

########################################################

# Huawei E1550

# Huawei E1750

#

# Contributor: Anders Blomdell, Ahmed Soliman

DefaultVendor=  0x12d1

DefaultProduct= 0x1446

TargetVendor=   0x12d1

TargetProduct=  0x1001

MessageContent="55534243123456780000000000000011060000000000000000000000000000"

       即可将此部分内容复制用来编写自己的配置文件(usb-modeswitch.setup,叫什么名字无所谓,只要在使用usb-modeswitch命令的时候,用“-c”来指定该文件即可),不过可能还需要根据实际检测到得ID信息来编写DefaultVendorDefaultProductTargetVendorTargetProduct等值。

u  使用命令行

使用命令行之前,需要usb_modeswitch –h来查看相应的usb_modeswitch命令,在根据

device_reference.txt文件中的相应信息,即可使用。

$ sudo usb_modeswitch -W -v 12d1 -p 1001 -V 12d1 -P 1001 -M

"55534243123456780000000000000011060000000000000000000000000000"

/*此命令行的作用相当于使用sudo usb_modeswitch -W –c usb_modeswitch.setu

usb_modeswitch.setup文件内容如下:

DefaultVendor=  0x12d1

DefaultProduct= 0x1001

TargetVendor=   0x12d1

TargetProduct=  0x1001

MessageContent="55534243123456780000000000000011060000000000000000000000000000"

*/

2 Ubuntu中识别E1750设备

       以下是我的系统上的做法,因为Windows系统中的设置已将VMware的自动USB检测给禁用了,提示Host USB disable,虚拟机右下角没有USB设备的标识。

解决方法:

1>windows系统中启动VM USB设备

在开始——>运行中执行services.msc命令,找到Vmware USB  Arbitration Service项,并启动。

2>重启虚拟机系统

关闭虚拟机,重新启动虚拟机系统。启动虚拟机系统后,系统右下角出现了USB连接的标识

3>连接windows中的E1750模块到虚拟机系统

点击右下角的USB标识,选择连接(从主机断开) ,弹出所示提示信息,选择OK

选择OK后,激活虚拟机中的USB设备,此时USB标识成激活状态,并且在虚拟机系统桌面上自动挂在WCDMA的标识

4>使用lsusb命令查看E1750设备ID等信息

$ lsusb    //显示当前挂在的USB模块信息

Bus 002 Device 002: ID 0e0f:0002 VMware, Inc. Virtual USB Hub

Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 001 Device 036: ID 12d1:1001 Huawei Technologies Co., Ltd. E620 USB Modem

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

3 设置usb-modeswitch配置文件

1>创建usb_modeswitch.setup配置文件

$ sudo gedit usb_modeswitch.setup   //新建usb_modeswitch.setup,写入如下器件模块信息

########################################################

# Huawei E1750

DefaultVendor=0x12d1

DefaultProduct=0x1446

TargetVendor=0x12d1

TargetProduct=0x1001

MessageContent="55534243123456780000000000000011060000000000000000000000000000"

       注:usb_modeswitch.setup中保存了要进行USB模式转换的设备ID的信息,可参考usb-modeswitch-1.1.7文件夹下的device_reference.txt文件来选择相应的设备信息。

        

2>加载usb_modeswitch.setup配置文件

$ sudo usb_modeswitch -c usb_modeswitch.setup

[sudo] password for user:

Looking for target devices ...

 Found devices in target mode or class (1)

Looking for default devices ...

 No devices in default mode found. Nothing to do. Bye.  //器件默认的模块类型错误

user@Ubuntu1004:/etc$

3>修改usb_modeswitch.setup配置文件

在虚拟终端中执行lsusb命令,打印当前挂在的USB设备,可看出3G模块的默认模块类型为0x12d1:0x1001

$ lsusb

4 安装wvdial拨号软件

       Wvdiallinux下的一款智能化拨号工具,利用wvdialppp可以实现linux下的轻松上网。在整个过程中,wvdial的作用是拨号并等待提示,并根据提示输入相应的用户名和密码等认证信息;ppp的作用是与拨入放协商传输数据的方法并维持该链接。使用wvdial时,需要使用/etc/wvdial.conf配置文件,这个配置文件可以自动生成,但是可能需要进行一点修改。Wvdial载入wvdial.conf配置文件后,会对modem进行初始化并拨号,拨号后等待拨入方的响应,收到拨入方响应后则启动pppd。注:pppdubuntu10.04上已经安装了,所以这里就不需要管它。

1>下载安装wvdail

$ sudo apt-get install wvdial

2>配置wvdail,创建/etc/wvdial.conf文件

$ sudo wvdialconf /etc/wvdial.conf

拨号方式

最大的区别是收费方式不一样。
前者  card 方式。就是所谓的掌中宽带方式。 以每分钟 6分钱计算 时长。
后面的 wap 和 brew 就是所谓的wap方式。。有5元包10M. 20元包50M 。还有 1元 包 1天( 限1G流量)

1、card 方式。
拨号电话: #777
用户名:card
密码:card

2、wap方式
拨号电话:#777
用户名:wap
密码: wap
代理服务器地址:10.0.0.200

3、brew方式
拨号电话:#777
有户名:ctwap@mycdma.cn
密码:vnet.mobi
代理服务器地址:10.0.0.200
