Linux系统通过手机GPRS上网设置.docx

Linux通过手机上网1.安装相关软件sudo apt-get install wvdial2.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 配置电脑上的usb0的IP为(4)运行 telnet telnet到手机，其中为手机usb lan的IP，如下$ telnet Trying .Connected to .Escape character is .MontaVista(R) Linux(R) Consumer Electronics Edition 3.1Linux/armv5tel 2.4.20_mvlcee31-mainstone_pxa27x(none) login: rootMontaVista(R) Linux(R) Consumer Electronics Edition 3.1No directory /root!Logging in with home = /.# ifconfig gprsv2 Link encap:Point-to-Point Protocol inet addr:75 P-t-P:12 Mask:55 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:50 RX bytes:8991 (8.7 Kb) TX bytes:5117 (4.9 Kb)lo Link encap:Local Loopback inet addr: Mask: UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:24 errors:0 dropped:0 overruns:0 frame:0 TX packets:24 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1392 (1.3 Kb) TX bytes:1392 (1.3 Kb)gprsv2 Link encap:Point-to-Point Protocol inet addr:8 P-t-P:12 Mask:55 UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:50 RX bytes:1025 (1.0 Kb) TX bytes:1023 (1023.0 b)# exitConnection closed by foreign host.$ (5)由(4)得到gprsv2的IP为8，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:8其中8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.Scanning your serial ports for a modem.WvModem: Cannot set information for serial port.ttyS0: ATQ0 V1 E1 - failed with 2400 baud, next try: 9600 baudttyS0: ATQ0 V1 E1 - failed with 9600 baud, next try: 115200 baudttyS0: ATQ0 V1 E1 - and failed too at 115200, giving up.Modem Port Scan: S1 S2 S3 WvModem: Cannot get information for serial port.ttyACM0: ATQ0 V1 E1 - OKttyACM0: ATQ0 V1 E1 Z - OKttyACM0: ATQ0 V1 E1 S0=0 - OKttyACM0: ATQ0 V1 E1 S0=0 &C1 - OKttyACM0: ATQ0 V1 E1 S0=0 &C1 &D2 - OKttyACM0: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 - OKttyACM0: Modem Identifier: ATI - ERRORttyACM0: Speed 4800: AT - OKttyACM0: Speed 9600: AT - OKttyACM0: Speed 19200: AT - OKttyACM0: Speed 38400: AT - OKttyACM0: Speed 57600: AT - OKttyACM0: Speed 115200: AT - OKttyACM0: Speed 230400: AT - OKttyACM0: Speed 460800: AT - OKttyACM0: Max speed is 460800; that should be safe.ttyACM0: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 - OKFound an USB modem on /dev/ttyACM0.Modem configuration written to /etc/wvdial.conf./etc/wvdial.conf: Cant write /etc/wvdial.conf.tmp8517: Permission denied/etc/wvdial.conf: Cant write /etc/wvdial.conf (/etc/wvdial.conf): Bad file descriptorttyACM0: Speed 460800; init ATQ0 V1 E1 S0=0 &C1 & D2 +FCLASS=0$ (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 DefaultsInit1 = ATZInit2 = AT&FE0V1&C1S0=0Init3 = AT+cgdcont=1,IP,CMNET,0,0Modem Type = USB ModemISDN = 0Phone = *99*2#New PPPD = yesModem = /dev/ttyACM0Username = 172Password = 172Baud = 460800Idle Seconds = 3000Auto DNS = 1Stupid Mode = 1Dial Command = ATDAsk Password = 0FlowControl = 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: ATZATZOK- Sending: AT&FE0V1&C1S0=0AT&FE0V1&C1S0=0OK- Sending: AT+cgdcont=1,IP,CMNET,0,0OK- Modem initialized.- Idle Seconds = 3000, disabling automatic reconnect.- Sending: ATD*99*2#- Waiting for carrier.CONNECT- Carrier detected.
