1. 安裝wvdial

sudo apt-get install wvdial

2. 在/etc/wvdial.conf中寫入wvdial的配置信息: femacs /etc/wvdial.conf

Init1 = ATZ

Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

Init3 = AT+CGDCONT=1,"IP","CMNET"  ##important! 否則無法使用DNS

Modem Type = Analog Modem

Baud = 115200  ##根據(jù)你的gprs modem來設(shè)定

New PPPD = yes

Modem = /dev/ttyS0 ##你所連接的串口

ISDN = 0

Phone = *99***1#  ##中國(guó)移動(dòng)的撥號(hào)號(hào)碼

Password = ***    ##其實(shí)沒什么用

Username = itlanger

這一步，可以首先運(yùn)行wvdial,這時(shí)會(huì)出現(xiàn)找不到modem,然后修改/etc/wvdial.conf, 增加

Baud = 115200  ##根據(jù)你的gprs modem來設(shè)定

Modem = /dev/ttyS0 ##你所連接的串口

然后再次運(yùn)行wvdial, 再手動(dòng)加入一下內(nèi)容到/etc/wvdial.conf：

Init3 = AT+CGDCONT=1,"IP","CMNET"

Phone = *99***1#  ##中國(guó)移動(dòng)的撥號(hào)號(hào)碼

Password = ***    ##其實(shí)沒什么用

Username = itlanger

這里Init3 = AT+CGDCONT=1,"IP","CMNET" 一定要加，否則wvdial撥號(hào)時(shí)會(huì)出現(xiàn)：

warning, can't find address for `www.suse.de`

--> warning, address lookup does not work

--> Nameserver (DNS) failure, the connection may not work.

導(dǎo)致只能ping通IP,不能ping通域名

3. 配置ppp參數(shù): femacs /etc/ppp/options

noipdefault

ipcp-accept-local

ipcp-accept-remote

defaultroute

noauth

crtscts

debug

4.撥號(hào)上網(wǎng): sudo wvdial

--> WvDial: Internet dialer version 1.60

--> Initializing modem.

--> Sending: ATZ

ATZ

OK

--> Sending: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0

OK

--> Sending: AT+CGDCONT=1,"IP","CMNET"

AT+CGDCONT=1,"IP","CMNET"

OK

--> Modem initialized.

--> Sending: ATDT*99***1#

--> Waiting for carrier.

ATDT*99***1#

CONNECT

~[7f]}#@!}!}#} }9}"}&} }*} } }'}"}(}"}%}&K_{}$}#}%B#}%<e~

--> Carrier detected.  Waiting for prompt.

~[7f]}#@!}!}#} }9}"}&} }*} } }'}"}(}"}%}&K_{}$}#}%B#}%<e~

--> PPP negotiation detected.

--> Starting pppd at Tue Dec 15 11:19:14 2009

--> Pid of pppd: 6666

--> Using interface ppp0

--> Authentication (CHAP) started

--> Authentication (CHAP) successful

--> local  IP address 10.24.229.233

--> remote IP address 192.168.254.254

--> primary   DNS address 211.137.160.5

--> secondary DNS address 211.136.17.107

--> Script /etc/ppp/ip-up run successful

--> Default route Ok.

--> Nameserver (DNS) Ok.

--> Connected... Press Ctrl-C to disconnect

4. 斷開以太網(wǎng)連接：

sudo ifconfig eth0 down

sudo route add default gw 10.24.229.233 ##這里是ppp0的IP

5. 測(cè)試網(wǎng)絡(luò):

ping 60.28.166.84

ping www.chinaunix.net

如果ping不通域名，可以cat /etc/resolv.conf

然后寫入撥號(hào)獲得的DNS
