Linux系統通過手機GPRS上網設置簡介

class="152524">

Linux通過手機上網

1.安裝相關軟件
;sudo apt-get install wvdial

2.得到GPRS的IP地址
;(1)
;手機調整到usb lan模式，在手機打開一個網頁，讓它的GPRS連通
;(2)
;運行 sudo /sbin/ifconfig
;確認usb0存在
;(3)
;運行 sudo /sbin/ifconfig usb0 192.168.1.1
;配置電腦上的usb0的IP為192.168.1.1
;(4)
;運行 telnet 192.168.1.2
;telnet到手機，其中192.168.1.2為手機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 '^]'.

# exit

;(5)
;由(4)得到gprsv2的IP為10.10.88.48，記錄下來

3.為pppd添加GPRS IP
;(1)
;運行 sudo gedit /etc/ppp/options
;在options文件的最後一行添加如下兩行內容
;novj
;:10.10.88.48
;其中10.10.88.48為2.(5)所得到的GPRS IP地址

4.配置/etc/wvdial.conf並連接上網
;(1)
;關掉手機的網頁，確認手機上的GPRS連接已經斷開
;(2)
;手機調整到usb modem模式
;(3)
;運行 wvdialconf
;檢測手機的modem連接是否正常，程序自動創建/etc/wvdial.conf文件，正確情況如下

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

;運行 sudo gedit /etc/wvdial.conf
;修改其內容，Baud保持4.(3)中程序自動創建的值，Username和Password的值到手機的網絡設置查看
;本例使用CMNET連接，文件內容如下

[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

;禁用eth0等網絡聯連接
;另：如果是在Debian Gnome環境下，右上角的網絡連接工具，“啟用聯網一項反選

(6)
;運行 sudo wvdial
;讓Linux通過手機上網，正常情況如下
