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# ##中國移動的撥號號碼
Password = *** ##其實沒什么用
Username = itlanger
這一步，可以首先運行wvdial,這時會出現(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
然后再次運行wvdial, 再手動加入一下內(nèi)容到/etc/wvdial.conf：
Init3 = AT+CGDCONT=1,"IP","CMNET"
Phone = *99***1# ##中國移動的撥號號碼
Password = *** ##其實沒什么用
Username = itlanger
這里Init3 = AT+CGDCONT=1,"IP","CMNET" 一定要加，否則wvdial撥號時會出現(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#

~[7f]}#@!}!}#} }9}"}&} }*} } }'}"}(}"}%}&K_{}$}#}%B#}% Carrier detected. Waiting for prompt.
~[7f]}#@!}!}#} }9}"}&} }*} } }'}"}(}"}%}&K_{}$}#}%B#}% 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
然后寫入撥號獲得的DNS
