移植PPP2.4.5到ARM进行TD-SCDMA网络的拨号

使用环境：
PC宿主机：sony VAIO Ubuntu10.10
ARM核心板：友善之臂micro2440的核心板
TD-SCDMA模块：SIMCOM Sim4200

1. 加入内核支持：
Device Drivers -> Network device support->PPP (point-to-point protocol) support
PPP multilink support (EXPERIMENTAL)
PPP support for async serial ports
PPP support for sync tty ports
PPP Deflate compression
PPP BSD-Compress compression


2. 下载ppp
wget -c ftp://ftp.samba.org/pub/ppp/ppp-2.4.5.tar.gz

3. 交叉编译
# ./configure
# make CC=arm-linux-gcc

4. 将目录下pppd chat pppdump pppstats下可执行程序pppd, chat, pppdump, pppstats拷贝到开发板/usr/sbin目录下

5. mkdir /etc/ppp; mkdir /etc/ppp/peers

然后建立如下4个文件：

1）/etc/ppp/peers/hsdpa------------------------------------------------------------------------------>

# example configuration for a dialup connection authenticated with PAP or CHAP
#
# This is the default configuration used by pon(1) and poff(1).
# See the manual page pppd(8) for information on all the options.

# MUST CHANGE: replace myusername@realm with the PPP login name given to
# your by your provider.
# There should be a matching entry with the password in /etc/ppp/pap-secrets
# and/or /etc/ppp/chap-secrets.
#user "myusername@realm"

# MUST CHANGE: replace ******** with the phone number of your provider.
# The /etc/chatscripts/pap chat script may be modified to change the
# modem initialization string.
#connect "/usr/sbin/chat -s -v -f /etc/chatscripts/pap -T ********"

connect "/usr/sbin/chat -s -v -f /etc/ppp/hsdpa-connect-chat"
# Serial device to which the modem is connected.
#/dev/modem
/dev/ttyUSB0

# Speed of the serial line.

nodetach
# Assumes that your IP address is allocated dynamically by the ISP.noipdefault
# Try to get the name server addresses from the ISP.
usepeerdns
# Use this connection as the default route.
defaultroute

# Makes pppd "dial again" when the connection is lost.
persist

# Do not ask the remote to authenticate.
noauth

defaultroute

asyncmap 0

#设置接入的用户名，在chap-secrests 和pap-secrets中使用
user "ming"

0.0.0.0:0.0.0.0 #本地和远端的ip都设为0使得接入的isp分配本地的ip地址

ipcp-accept-local #要求peer也就是isp给自己分配动态的ip地址

#ipcp-accept-remote
#lcp-echo-failure 12
#lcp-echo-interval 3
noccp #不需要压缩控制协议，有可能对端不需要，根据自己的isp的情况确定
#novj
#novjccomp
#-mn


2) /etc/ppp/hsdpa-connect-chat------------------------------------------------------->

TIMEOUT 15

ABORT "NO CARRIER"

3) /etc/ppp/pap-secrets------------------------------------------------------------->

#
# /etc/ppp/pap-secrets
#
# This is a pap-secrets file to be used with the AUTO_PPP function of
# mgetty. mgetty-0.99 is preconfigured to startup pppd with the login option
# which will cause pppd to consult /etc/passwd (and /etc/shadow in turn)
# after a user has passed this file. Don't be disturbed therefore by the fact
# that this file defines logins with any password for users. /etc/passwd
# (again, /etc/shadow, too) will catch passwd mismatches.
#
# This file should block ALL users that should not be able to do AUTO_PPP.
# AUTO_PPP bypasses the usual login program so it's necessary to list all
# system userids with regular passwords here.
#
# ATTENTION: The definitions here can allow users to login without a
# password if you don't use the login option of pppd! The mgetty Debian
# package already provides this option; make sure you don't change that.

# INBOUND connections

# Every regular user can use PPP and has to use passwords from /etc/passwd
*    hostname    ""    *

# UserIDs that cannot use PPP at all. Check your /etc/passwd and add any
# other accounts that should not be able to use pppd!
guest    hostname    "*"    -
master    hostname    "*"    -
root    hostname    "*"    -
support    hostname    "*"    -
stats    hostname    "*"    -

# OUTBOUND connections

# Here you should add your userid password to connect to your providers via
# PAP. The * means that the password is to be used for ANY host you connect
# to. Thus you do not have to worry about the foreign machine name. Just
# replace password with your password.
# If you have different providers with different passwords then you better
# remove the following line.

#    *    password
ming * 123456 *

4) /etc/ppp/chap-secrets------------------------------------------------------->

# Secrets for authentication using CHAP
# client    server    secret            IP addresses
ming * 123456 *


6. 进行拨号连接:
拨号前需要先启动Sim4200板子，然后在通过usbserial把Sim4200的接口转换为虚拟的串口ttyUSB*，使用
ttyUSB0来进行拨号的。
在终端输入modprobe usbserial vendor=0x1e0e product=0xde19就可以进行转换来，如果转换出问题
的话，可能是你的usbserial安装有问题的，mini2440自带的linux镜像里面是把usbserial编译到内核里面
但是他们是无法识别出Sim4200的，要么你就重新修改对于的usbserial的option，然后把usbserial编译到
内核，或者重新编译下内核，把usbserial编译成为模块。下面的这个命令的使用是把usbserial编译成模块的。
具体的操作看Sim42XX的文档。

[root@FriendlyARM ppp]# modprobe usbserial vendor=0x1e0e product=0xde19         
usbcore: registered new interface driver usbserial                              
USB Serial support registered for generic

usbserial_generic 1-1.1:1.3: generic converter detected

usbserial_generic 1-1.1:1.4: generic converter detected

usb 1-1.1: generic converter now attached to ttyUSB5                            
usbcore: registered new interface driver usbserial_generic                      
usbserial: USB Serial Driver core  


然后再通过 pppd call hsdpa就可以进行拨号。

拿到来这几个IP就证明拨通来，可以试试ping下IP。

***sim4200也可以使用gprs来拨号的，对于的设置和文件我自己是以gprs开头的。
和hsdpa一样有gprs 和gprs-connect-chat。其余的不变。
