服务器评测
一、 PPP移植
各项工作具体说明
向Linux内核添加3G模块的驱动(USB转串口驱动)和PPP协议的支持，然后编译内核并下载到开发板。当然如果之前已经移植好内核,那么只需要增加几个选项就可以,然后在编译内核就可以了,这个文档默认内核已经移植过,所以只讲与USB转串口驱动和PPP协议支持的几个选项。
[linuxidc@localhost linux-3.0]$ make menuconfig
1、USB的驱动要选这几个：
DeviceDrivers—→
USBsupport—→
<*>USB SerialConverter support–→
[*]USBGeneric Serial Driver
<*>USBdriver for GSM and CDMA modems
2、到此3G模块驱动添加完成，下面进行ppp协议支持的添加（下面所示的几个选项必选）：
DeviceDrivers–→
Network devicesupport—→
<*> 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
完成了这些步骤以后就可以退出make menuconfig进行make编译内核了。然后再把生成的镜像文件下载到板子上重启开发板即可。然后就会发现在/dev/目录下生成ppp设备节点：
~ >: ls -l dev/ppp
crw-rw—- 1 root root 108, 0 Mar 27 17:35 dev/ppp

二、 usb_modeswitch移植
下载usbmode库：
[linuxidc@localhost fulinux]$ mkdir usbmode
[linuxidc@localhost fulinux]$ cd usbmode/
[linuxidc@localhost usbmode]$ wget http://pkgs.Fedoraproject.org/repo/pkgs/libusb1/libusb-1.0.0.tar.bz2/df2447c23750ef2b4a314200feacc2ee/libusb-1.0.0.tar.bz2
[linuxidc@localhost usbmode]$ wget http://jaist.dl.sourceforge.net/project/libusb/libusb-compat-0.1/libusb-compat-0.1.5/libusb-compat-0.1.5.tar.bz2
[linuxidc@localhost usbmode]$wget http://pkgs.fedoraproject.org/repo/pkgs/usb_modeswitch/usb-modeswitch-1.2.4.tar.bz2/dbd4ce7966d7b4a5a0604a8280f7164d/usb-modeswitch-1.2.4.tar.bz2
[linuxidc@localhost usbmode]$ wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-20130607.tar.bz2
以上这些下载地址如果有失效的，搜索相应的文件下载，即可下载。
解压：
[linuxidc@localhost usbmode]$ tar xjf libusb-1.0.0.tar.bz2
[linuxidc@localhost usbmode]$ tar xjf libusb-compat-0.1.5.tar.bz2
[linuxidc@localhost usbmode]$ tar xjf usb-modeswitch-1.2.6.tar.bz2
[linuxidc@localhost usbmode]$ tar xjf usb-modeswitch-data-20130607.tar.bz2
编译libusb：
[linuxidc@localhost usbmode]$ mkdir install
[linuxidc@localhost usbmode]$ cd libusb-1.0.0
[linuxidc@localhost libusb-1.0.0]$ ./configure –prefix=/home/linuxidc/fulinux/usbmode/install/ –build=i686 –host=arm-linux –disable-shared –enable-static （注意有两–的前面有一个空格）
[linuxidc@localhost libusb-1.0.0]$ make
[linuxidc@localhost libusb-1.0.0]$ make install
[linuxidc@localhost libusb-1.0.0]$ ls ../install/
include lib
[linuxidc@localhost libusb-1.0.0]$
编译usb_modeswitch：
[linuxidc@localhost usbmode]$ cd usb-modeswitch-1.2.6
[linuxidc@localhost usb-modeswitch-1.2.6]$ ls
[linuxidc@localhost usb-modeswitch-1.2.6]$ vim Makefile
CC ?=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc #addr fulinux
CFLAGS += -Wall -l ../install/include-static #add by fulinux
LIBS = -L ../install/lib/ -l usb -l usb-1.0-l pthread #add by fulinux
[linuxidc@localhost libusb-1.0.0]$ cd ..
[linuxidc@localhost usbmode]$ export PKG_CONFIG_PATH=/home/linuxidc/fulinux/usbmode/install/lib/pkgconfig:$PKG_CONFIG_PATH
[linuxidc@localhost usbmode]$ cd libusb-compat-0.1.5
[linuxidc@localhost libusb-compat-0.1.5]$
[linuxidc@localhost libusb-compat-0.1.5]$ ./configure –prefix=/home/linuxidc/fulinux/usbmode/install/ –build=i686 –host=arm-linux –disable-shared –enable-static
[linuxidc@localhost libusb-compat-0.1.5]$ make
[linuxidc@localhost libusb-compat-0.1.5]$ make install
[linuxidc@localhost libusb-compat-0.1.5]$ ls ../install/
bin include lib
[linuxidc@localhost libusb-compat-0.1.5]$
编译usb_modeswitch：
[linuxidc@localhost libusb-compat-0.1.5]$ cd ../usb-modeswitch-1.2.4
[linuxidc@localhost usb-modeswitch-1.2.6]$ vim Makefile
CC = /opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc
CFLAGS += -Wall -I ../install/include -static
LIBS = -L ../install/lib -l usb -l usb-1.0 -l pthread
[linuxidc@localhost usb-modeswitch-1.2.4]$ make
[linuxidc@localhost usb-modeswitch-1.2.4]$ cp usb_modeswitch ../install/bin/
[linuxidc@localhost usb-modeswitch-1.2.4]$ cp usb_modeswitch /tftp/
上面用usb-modeswitch-1.2.6编译时发现有问题，有如下
[linuxidc@localhost usb-modeswitch-1.2.6]$ make
cc -o usb_modeswitch usb_modeswitch.c -Wall -I../install/include -static -L /home/linuxidc/fulinux/usbmode/install/lib -l usb -l usb-1.0 -l pthread
/usr/bin/ld: skipping incompatible /home/linuxidc/fulinux/usbmode/install/lib/libusb.a when searching for -lusb
/usr/bin/ld: cannot find -lusb
collect2: ld returned 1 exit status
make: *** [usb_modeswitch] Error 1
[linuxidc@localhost usb-modeswitch-1.2.6]$
“incompatible”库和这个有冲突。建议使用。1.2.6一下的版本。
把usb-modeswitch-data-20130607下的usb_modeswitch.d中的所有文件都拷贝到开发板的etc/usb_modeswitch.d/目录：
[linuxidc@localhost usbmode]$ cd usb-modeswitch-data-20130607
[linuxidc@localhost usb-modeswitch-data-20130607]$ ls
40-usb_modeswitch.rules ChangeLog COPYING gen-rules.tcl Makefile README usb_modeswitch.d
[linuxidc@localhost usb-modeswitch-data-20130607]$ tar cjf usb_modeswitch.d.tar.bz2 usb_modeswitch.d/
[linuxidc@localhost usb-modeswitch-data-20130607]$ ls
40-usb_modeswitch.rules ChangeLog COPYING gen-rules.tcl Makefile README usb_modeswitch.d usb_modeswitch.d.tar.bz2
[linuxidc@localhost usb-modeswitch-data-20130607]$ cp usb_modeswitch.d.tar.bz2 /tftp/
[linuxidc@localhost usb-modeswitch-data-20130607]$
把usb_modeswitch下载到开发板的/usr/sbin目录下，把usb_modeswitch.d下载开发板到/etc/目录下：
/usr/sbin >: tftp -gr usb_modeswitch 192.168.1.3
usb_modeswitch 100% |*******************************| 390k 0:00:00 ETA
/etc >: tftp -gr usb_modeswitch.d.tar.bz2 192.168.1.3
usb_modeswitch.d.tar 100% |*******************************| 8741 0:00:00 ETA
/etc >: tar xjf usb_modeswitch.d.tar.bz2
三、pppd和chat
交叉编译好工作源代码ppp-2.4.4，得到pppd和chat，解压源代码包,进入目录,进行交叉编译：
[linuxidc@localhost fulinux]$ mkdir ppp
[linuxidc@localhost fulinux]$ cd ppp/
[linuxidc@localhost ppp]$ wget ftp://ftp.samba.org/pub/ppp/ppp-2.4.4.tar.gz
[linuxidc@localhost ppp]$ tar zxf ppp-2.4.4.tar.gz
[linuxidc@localhost ppp]$ cd ppp-2.4.4
[linuxidc@localhost ppp-2.4.4]$ ./configure
[linuxidc@localhost chat]$ linux
[linuxidc@localhost chat]$ vim chat.c
1168 if (timeout_next) {
1169 timeout_next = 0;
1170
1171 s = clean(s,0); /* add by fulinux */
1172
1173 timeout = atoi(s);
1174
1175 free(s); /* add by fulinux */
1176
1177 if (timeout <= 0)
[linuxidc@localhost chat]$ vim Makefile
INSTALL= install
CC=/opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc #add by fulinux
all: chat
chat: chat.o
$(CC) -static -o chat chat.o #add by fulinux
[linuxidc@localhost chat]$ cd ../pppd
[linuxidc@localhost pppd]$ vim auth.c
1316 ao->neg_upap = !refuse_pap /*&& (passwd[0] != 0 || get_pap_passwd(NULL))*/; /* add by fulinux*/
[linuxidc@localhost pppd]$ vim Makefile
33 CC = /opt/buildroot-2012.08/arm920t/usr/bin/arm-linux-gcc # add by fulinux
46#MPPE=y
51#FILTER=y
68#PLUGIN=y
[linuxidc@localhost pppd]$ cd ..
[linuxidc@localhost ppp-2.4.4]$ make
make[1]: Leaving directory `/usr/local/src/linuxidc/fulinux/ppp/ppp-2.4.4/pppdump’
[linuxidc@localhost ppp-2.4.4]$ cd chat/
[linuxidc@localhost chat]$ ls
chat chat.8 chat.c chat.o Makefile Makefile.linux Makefile.sol2
[linuxidc@localhost chat]$ file chat

[linuxidc@localhost pppd]$ file pppd
pppd: ELF 32-bit LSB executable, ARM, version 1 (SYSV), dynamically linked (uses shared libs), not stripped
[linuxidc@localhost pppd]$
将交叉编译出来的这两个应用程序chat和pppd拷贝到开发板 /usr/sbin目录下，更改其属性为可执行文件。
[linuxidc@localhost chat]$ cp chat /tftp/
[linuxidc@localhost pppd]$ cp pppd /tftp/
在开发板中操作：
~ >: cd usr/sbin/
/usr/sbin >: tftp -gr chat 192.168.1.3
chat 100% |*******************************| 147k 0:00:00 ETA
/usr/sbin >: tftp -gr pppd 192.168.1.3
pppd 100% |*******************************| 621k 0:00:00 ETA
/usr/sbin >: chmod a+x chat
/usr/sbin >: chmod a+x pppd
配置拨号的脚文件
拨号上网需要的配置文件有3个：
wcdma,wcdma-chat-connect,wcdma-chat-disconnect（存放位置是开发板的/etc/ppp/peers）。
~ >: mkdir -p /etc/ppp/peers/
wcdma配置文件内容
# /etc/ppp/peers/wcdma
# This is pppd script for China liantong
# Usage: root>pppd call cdma
hide-password
noauth
connect ‘/usr/sbin/chat -s -v -f /etc/ppp/peers/wcdma-chat-connect’

SAY “\nGood bye\n”
还要添加一个域名解析的文件：
nameserver 4.2.2.2
nameserver 8.8.8.8
将上面的四个文件拷贝到/tftp目录下。
并下载到开发板相应的目录中去：
因为
lrwxrwxrwx 1 root root 29 Apr 21 2013 resolv.conf -> /apps/etc/network/resolv.conf
所以：
/apps/etc/network >: tftp -gr resolv.conf 192.168.1.3
~ >: cd etc/ppp/peers/
/etc/ppp/peers >: ls
/etc/ppp/peers >: tftp -gr wcdma 192.168.1.3
/etc/ppp/peers >: tftp -gr wcdma-chat-disconnect 192.168.1.3
/etc/ppp/peers >: tftp -gr wcdma-chat-connect 192.168.1.3
/etc/ppp/peers >: ls
wcdma wcdma-chat-connect wcdma-chat-disconnect
到这里PPP 移植就完成了。
到了这里大部分工作已经完成了，但是我们的开发板依然不能拨号，还需进一步修改和添加配置文件。
当我们的MF626插件中兴WCDMA USB调制解调器,Linux内核识别作为一个cd – rom。
scsi0 :usb-storage 1-1.4:1.0
scsi 0:0:0:0: CD-ROM ZTE USB SCSI CD-ROM 2.31 PQ: 0 ANSI: 2
现在我们需要使用usb_modeswitch切换3 g USB调制解调器来调制解调器(USB转换为seiral)，对于usb_modeswitch使用libusb,libusb依赖于USB文件系统。所以我们在使用usb_modeswitch之前必须挂在usbfs，否则它不能检测USB设备。
添加中兴WCDMA现代usb_modeswitchMF626配置文件：
~ >: cd apps/
/apps >: vi zte_mf626.conf
#ZTE devices
DefaultVendor = 0x19d2
DefaultProduct= 0x2000
TargetVendor = 0x19d2

MessageContent3 = “55534243123456702000000080000c85010101180101010101000000000000”

Looking for target devices …
No devices in target mode or class found
Looking for default devices …
No devices in default mode found. Nothing to do. Bye.
这是因为usbfs文件系统没有挂在起来，所以使用usb_modeswitch之前要挂载它：
/apps >: mount -tusbfs usbfs /proc/bus/usb/
/apps >: mount
rootfs on / type rootfs (rw)
/dev/root on / type jffs2 (rw,relatime)
proc on /proc type proc (rw,relatime)
usbfs on /proc/bus/usb type usbfs (rw,relatime)
tmpfs on /dev type tmpfs (rw,relatime)
ramfs on /tmp type ramfs (rw,relatime)
sysfs on /sys type sysfs (rw,relatime)
devpts on /dev/pts type devpts (rw,relatime,mode=600)
ubi7:apps on /apps type ubifs (rw,sync,noatime)
/dev/mtdblock8 on /data type jffs2 (rw,sync,noatime)
/apps >:
~ >: ls proc/bus/usb/
001 devices
这样我usbfs就挂载起来了，但是如果重启开发板后，还得重新挂载，为了每次启动系统都能自动挂载，我们进行如下修改：
~ >: cd etc/
/etc >: vim fstab
# /etc/fstab: static file system information.
#
# <file system> <mount pt> <type> <options> <dump> <pass>
/dev/root / ext2 rw,noauto 0 1
proc /proc proc defaults 0 0
usbfs /proc/bus/usb usbfs defaults 0 0
tmpfs /dev tmpfs defaults 0 0
ramfs /tmp ramfs defaults 0 0
sysfs /sys sysfs defaults 0 0

现在的话就可以看到如下信息了：
~ >: usb_modeswitch -c /apps/zte_mf626.conf

或设置APN为3gnet:
AT+CGDCONT=1,”IP”,”3gnet”
OK
AT+CGDCONT?
+CGDCONT:1,”IP”,”3gnet”,”0.0.0.0″,0,0
OK
短信相关命令：
设置短信格式为Text模式：
AT+CMGF=1
OK
设置短信格式为PDU模式：
AT+CMGF=0
OK
设置短信中心号，一般不需要我们手动设置。
湖北联通的短信中心号设置如下：

最后登录一下水木年华bbs
更多详情见请继续阅读下一页的精彩内容： http://www.linuxidc.com/Linux/2016-03/129579p2.htm
一、发送text格式的短信
给联通发text格式的短信：
~ >: microcom -s 115200 /dev/ttyUSB1
at
OK
设置短信格式为Text模式：
at+cmgf=1
OK
at+cmgs=”+861300711**** “
输入发送的内容：
> hello （内容写完后按一下ctrl + z发送）
+CMGS: 48
OK
给电信发text格式的短信：
~ >: microcom -s 115200 /dev/ttyUSB1
at
OK
设置短信格式为Text模式：
at+cmgf=1
OK
at+cmgs=”+861532736**** “
设置短信格式为Text模式：
> hello （内容写完后按一下ctrl + z发送）
+CMGS: 48
二、发送PDU格式的短信
接收号码:+8613007110996
短信内容:工作愉快！
武汉中心号码:+8613800270500
1、短信中心号码处理：用字符串 addr 表示
a、将短信息中心号码去掉+号，看看长度是否为偶数，如果不是，最后添加F
即 addr = “+8613800100500”
=> addr = “8613800270500F”
b、将奇数位和偶数位交换。
=> addr = “683108200705F0”
c、将短信息中心号码前面加上字符91，91是国际化的意思
=> addr = “91683108200705F0”
d、算出 addr 长度，结果除2，格式化成2位的16进制字符串，16 / 2 = 8 => “08”，并放到addr前面去。
=> addr = “0891683108200705F0”
2、手机号码处理：用字符串 phone
a、将手机号码去掉+号，看看长度是否为偶数，如果不是，最后添加F
即 phone = “+8613007110996”
=> phone = “8613007110996F”
b、将手机号码奇数位和偶数位交换。
=> phone = “683100170199F6”
3、短信息部分处理：用字符串 msg 表示
a、转字符串转换为Unicode代码，转换方法为：
下载一个汉字Unicode编码转换器，当输入“工作愉快！” 时
转换为的是十进制24037 20316 24841 24555 65281 ，再利用计算器五个一转换，例如24037转换为十六进制的5DE5，
最终转换为的十六进制连起来就是5DE54F5C61095FEBFF01 (转换在linux里可用iconv函数实现。)
b、将 msg 长度除2，保留两位16进制数，即 5DE54F5C61095FEBFF01 = 20 / 2 => “0A”，再加上 msg
=> msg = “0A5DE54F5C61095FEBFF01”
4、组合
a、手机号码前加上字符串 11000D91（1100：固定，0D：手机号码的长度，不算＋号，十六进制表示，91：发送到手机为91，发送到小灵通为81）
即 phone = “11000D91” + phone
=> 11000D91683100170199F6
b、手机号码后加上 000800 和刚才的短信息内容，000800也写死就可以了
即 phone = phone + “000800” + msg
即 11000D91683100170199F6 + 000800 + 0A5DE54F5C61095FEBFF01
=> phone = 11000D91683109423346F90008000A5DE54F5C61095FEBFF01
c、phone 长度除以2，格式化成2位的十进制数
即 11000D91683100170199F60008000A5DE54F5C61095FEBFF01 => 50位 / 2 => 25
5、note = addr+phone ==> 0891683108200705F011000D91683100170199F60008000A5DE54F5C61095FEBFF01
5、所以要发送的内容为
发：AT
收：OK
发：AT+CMGF=0
收：OK
发：AT+CMGS=25
收：>
发：note —> //”—>”为发送符（ctrl+z,十六进制0x1A）
收：+CMGS: 50
OK
6、如果返回不是ERROR，恭喜你，发送成功了。如果返回+CMS ERROR: 304，说明格式还是有问题，要检查一下。
一、用text查看模式
下面的“发”是指我敲的命令，“收”是指回车后显示的信息包括其他接收的信息。
~ >: microcom -s 115200 /dev/ttyUSB1
发：at
收：OK
设置成文本模式读:
发：at+cmgf=1
收：OK
将信息保存在SIM卡中:
发：at+cpms=”SM”,”SM”,”SM”
收：+CPMS: 0,50,0,50,0,50
收：OK
等待接收短信。。。。。。
收到了会有这个提示信息：
收：+CMTI: “SM”,0
查看信息:
发：at+cmgl=”rec unread”
收：+CMGL: 0,”REC UNREAD”,”+8613135699576″,,”13/07/14,22:11:10+32″
收：4F60597D
经过一个unicode转换器4F60597D ===>你好
收：OK
二、PDU模式查看
下面取网上一个例子
假设终端收到的短信为:
+CMT: ,24
0891683108200205F0240D91683157121468F0000860800331220000044F60597D
现在的任务是逆编码，从而获得信息。
下面分析一下接收到的PDU数据：
（1）08 //信息中心号码的长度,将91+683108200205F0的长度除2,格式化成2位的16进制字符串所得
（2）91 //短信中心号码类型
（3）683108200205F0 //短信中心号码，转换方法前面有提到
==>+8613800220500
（4）24 //TPDU头字节
（5）0D //发送源号码长度，8613752141860的长度格式化为2位16进制所得
（6）91 //发送源号码类型
（7）683157121468F0 //发送源号码,发送端的号码为:
==>+8613752141860
（8）00 //协议标识 TP—PID
（9）08 //数据编码方案，08：中文编码，00为英文或数字,Bit No.7与Bit No.6
（10）608003312200 //日期时间，奇偶互换：06-08-30 13:22:00,有论坛上写接收到的是026080……就是前面有’02’,表示2006-08…但是我用不同的手机发送短信过来接收到的都是06,无法取得2006,不知道是发送方手机设置的问题还是哪里的问题,还在研究中.
（11）00 //时区
（12）04 //用户数据长度TP-UDL（TP-User-Data-Length）,4F60597D的长度除2格式化为2位16进制数所得
(13) 4F60597D //”你好”的UNICODE码:
在提供一个例子：
PDU模式查看
终端收到的短信提示信息:
+CMTI: “SM”,2
+CMGL: 2,0,,28
0891683108200705F4240D91685123377660F0000831704132305423084F60597D00200020
