Linux (UBUNTU) PPP dial-up online learning notes

Environment:

OS: ubuntu10.04 64bit

TD module: lc6311 +

1. Load the device driver

First, we need to drive the TD module. We need to load the usbserial. Ko driver and specify the vendorid and productid:

Sudo modprobe usbserial vendor = 0x1ab7 Product = 0x6000

After the driver is loaded, connect the module to the computer through USB and identify several devices: ttyusb0 ttyusb1 ttyusb2 ttyusb3 ttyusb4 ttyusb5. We need to use ttyusb5.

2. Download and compile the PPP source code:

Download the source code and compile and install the three steps:

./Configure

Make

Make install

After compilation, several pppd, chat, pppump, and pppstats files will be generated. In fact, we use the pppd and chat programs.

3. Dial-up surfing script:

There are many scripts on the Internet, but they may be slightly different based on different hardware, because some AT commands are involved.

Dialing script/etc/PPP/peers/GPRS-dial:

hide-passwordnoauthconnect "/usr/local/sbin/chat -v -t 50 -f /etc/chatscripts/gprs-chat"debug/dev/ttyUSB5460800defaultroutenoipdefaultlocallockdumpnodetachuser " "remotename cmnetipparam cmnetusepeerdns

Chat script/etc/chatscripts/GPRS-chat:

#TIMEOUT 15ABORT '\nBUSY\r'ABORT '\nNO ANSWER\r'ABORT '\nRINGING\r\n\r\nRINGING\r'ABORT '\n+CME ERROR: 100\r'#" AT#'OK-+++\c-OK' ATH0#TIMEOUT 40#" \rAT'' ATZ#OK ATS0=0#OK ATE0V1OK AT+CGDCONT=1,"IP","CMNET"OK AT+CGEQREQ=1,2,128,384,0,0,0,0,"0E0","0E0",,0,0OK ATDT*98*1#CONNECT

4. Start pppd

Sudo pppd call GPRS-dial

If the operation succeeds, the following information is returned:

local  IP address 10.107.109.49remote IP address 192.168.0.1primary   DNS address 120.196.165.7secondary DNS address 221.179.38.7Script /etc/ppp/ip-up started (pid 4162)Script /etc/ppp/ip-up finished (pid 4162), status = 0x0
