4.             上网

使用pppd上网(只是上网方式中的一种,其他方式如:NetWorkManagerKPPP)

To connect using the manual pppd method you will need to download the pppd scripts .

1. Navigate to the directory that contains pppd-scripts.tar.gz and extract it to the default location by typing the following commands:
$ cd "directory"
$ tar -zxf pppd-scripts.tar.gz

2. Switch to root and copy the files to the ppp/peers directory by typing the following commands:
# su
# cp -r ./ppp /etc/
# cd /etc/ppp
# chmod a+x ip-up.local ip-down.local

3. If using a GSM/UMTS device follow these steps to set the authentication settings; otherwise, skip this step:

a. # cd /etc/ppp/peers

b. # vi ./gsm_chat (You may use other editing programs such as emacs or gedit to edit the script)

c. Go to the APN section and replace the listed APN with that of your service provider (e.g. If your service provider is AT&T, you would type in isp.cingular).

d. There are a few sample APN lines listed in the script that can be tried.

e. Save and exit.

4. Test the connection by typing the following command (you may need to use the root account to run pppd):

a. For CDMA devices:
# pppd call cdma

b. For GSM/UMTS devices:
# pppd call gsm

c. For Aircard 885E, MC8785, C885 devices:
# pppd call gsm885

5. If the connection test is not successful; further authentication may be required.

a. # vi ./gsm (You can use other editing programs such as emacs or gedit)

b. Put a '#' next to the "noauth" line (this disables the line).

c. Remove the '#' next to the user and password lines.

d. Type in the appropriate user name and password. (Contact your service provider if you do not know what these are.)

e. Some pppd version may not correctly set up the dynamic DNS configuration. It may be necessary to copy or link /etc/ppp/resolv.conf to /etc/resolv.conf.
