wpa_supplicant.conf Wpa_supplicant是linux系统下一个非常强大的无线网卡管理程序

使用心得一
编译完成后可以发现有几个可执行程序：wpa_supplicant，wpa_cli等。wpa_supplicant是核心程序，它和wpa_cli的关系就是服务和客户端的关系：后台运行wpa_supplicant，可以使用wpa_cli来搜索、设置、和连接网络等，大部分情况下编辑好配置文件，运行wpa_supplicant就可以连通网络了，创建一个wpa_supplicant.conf，键入以下内容：
#可有可无，没有的话无法用wpa_cli terminate来关闭wpa_supplicant
ctrl_interface=/var/run/wpa_supplicant

# 确保只有root用户能读取WPA的配置，可有可无，尤其是在嵌入式设备上
ctrl_interface_group=0

# 使用wpa_supplicant来扫描和选择AP，也可以设置成0或2，但只有1才能正确工作
ap_scan=1

network={
#AP的名字
ssid="my_network"
#AP的key
psk="my_key"
} 配置文件弄好后就可以运行wpa_supplicant了。在那之前当然要先插好无线网卡，载入驱动：------------------------------------------------------

bash# insmod zd1211b.ko
bash# ifconfig eth1 up
bash# wpa_supplicant -B -ieth1 -Dzydas -c/etc/wpa_supplicant.conf

参数-B代表后台运行，-ieth1代表使用设备eth1，-Dzydas代表网卡芯片是zydas，-c指定配置文件。
接下来就可以看下网络是否连通了：

bash# iwconfig
bash# udhcpc -i eth1 -n

zd1211b的驱动使用wpa_supplicant来配置的时候会有隔段时间就锁死系统一会的情况，很奇怪。
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
使用心得二

wpa_supplicant的使用主要是配置wpa_supplicant.conf，以下是一个配置文件的例子：

#可有可无，没有的话无法用wpa_cli terminate来关闭wpa_supplicant

ctrl_interface=/var/run/wpa_supplicant

# 确保只有root用户能读取WPA的配置，可有可无，尤其是在嵌入式设备上

ctrl_interface_group=0

# 使用wpa_supplicant来扫描和选择AP，也可以设置成0或2，但只有1才能正确工作

ap_scan=1

network={

#AP的名字

ssid="my_network"

#AP的key

psk="my_key"

}

配置文件弄好后就可以运行wpa_supplicant了：

wpa_supplicant–B –i wlan0 –c /etc/tkip.conf

后台运行wpa_supplicant（自动打开wifi模块wlan0，自动搜索AP并连接），参数-B为后台运行，-i为wifi设备，-c指定wpa_supplicant配置文件

wlan0自动获取IP：

udhcpc–i wlan0

接下来就可以看下网络是否连通了：
iwconfig
udhcpc -i wlan0 -n

popen() 函数通过创建一个管道，调用 fork 产生一个子进程，执行一个 shell 以运行命令来开启一个进程。这个进程必须由 pclose() 函数关闭，而不是 fclose() 函数。pclose() 函数关闭标准 I/O 流，等待命令执行结束，然后返回 shell 的终止状态。如果 shell 不能被执行，则 pclose() 返回的终止状态与 shell 已执行 exit 一样。

在第一次使用TortoiseSVN从服务器CheckOut的时候，会要求输入用户名和密码，这时输入框下面有个选项是保存认证信息，如果选了这个选项，那么以后就不用每次都输入一遍用户名密码了。

不过，如果后来在服务器端修改了用户名密码，则再次检出时就会出错，而且这个客户端很弱智，出错之后不会自动跳出用户名密码输入框让人更新，我找了半天也没找到修改这个用户名密码的地方。

最终，找到两种解决办法：

办法一：在TortoiseSVN的设置对话框中，选择“已保存数据”，在“认证数据”那一行点击“清除”按钮，清楚保存的认证数据，再检出的时候就会重新跳出用户名密码输入框。

如果方法一不起作用，则可以采用方法二：

Tortoise的用户名密码等认证信息都是缓存在客户端文件系统的这个目录：

C:/Documents and Settings/Administrator/Application Data/Subversion/auth

删除auth下面的所有文件夹，重新连接远程服务器进行检出，对话框就会出现！

hostapd各参数含义：

http://laoding.blog.51cto.com/980622/1697015

设置概要:
ssid: 设置名字(SSID = service set identifier) ,老版本(iwconfig)叫"essid".
hw_mode: 设置操作mode,channels.有效的值取决于硬件,通常:a, b, g
channel:设置hostapd操作的channel.
ssid很容易配置..
hw_mode需要你的硬件支持.'g'大多数都支持, 并向前兼容802.11b..
channel应该与其他AP被选择在 20mhz (4 channels)之外，或者每边10mhz (2 channels).这就意味着一个在channel 3的一个AP将干涉channel 1或者channel 5的AP.选择一个channel.通常用户的APs默认channel 6, 因此你使用channel 1或channel 11大多数情况下最佳. channels也依赖于本地规则.

这里要注意的是，如果网卡工作在5G下，虽然根据802.11a的标准，5G下的信道从60到165之间有许多许多，而使用iwlist查询到的网卡信息也说明网卡支持这些信道，但也许channel配置项只能写149以上的值。因为我国的5G信道只允许使用149以上的信道。
2 hwmode：工作在什么标准下
hwmode和channel是对应的，例如，如果channel是149，意味着网卡工作在5G下，那么hwmode不能写11g，因为11g标准定义的通信频率是不包含5G的，只有11a才可以。
hwmode的值不能乱写（这也是我今天才知道的）。合法的值有：11a 11b 11g 11na 11ng等。使用其他奇怪的值，也许在网卡服务启动的时候内核不会complain，也许网络服务开启后，并非不能正常地部署好AP，但配置也许是错误的：在我的实验中，我需要将AP配置到11n下，但由于把hwmode的值写成了11an，结果并未如我所愿，网卡其实工作在了11a标准下，此时虽然可以建立AP，可以ping通，但是11n并未启用，不符合我的需求。
原因可以用下面这段shell来说明。在解析配置文件的时候，是下面代码中第8行开始的这段case代码来解析的，从前往后依次尝试匹配11bg、11a、11b、11g，然后是11n*（也就是11na、11ng），然后是其他（用$default作为hwmode的值）。

在设备里查看：移植到开发环境里install_root目录
[root@localhost ~]# cd /
[root@localhost /]#
[root@localhost /]# ls usr/lib/libiw.so.29

该问题主要是因为无线数据传输校验中随机种子数较少导致的无线网络数据传输时延过大导致的，
用户可以通过命令cat /proc/sys/kernel/random/entropy_avail来查看具体数值，该值一般小于1000，
用户需要通过在终端中执行yum install haveged命令安装随机数生成器（haveged），
并使用systemctl enable haveged.servce命令来启动随机数生成器（haveged）已提高entropy_avail数值。这样无线网络时延将恢复到正常状态。网络不在出现以上描述的问题。

# mv /dev/random /dev/random.org
# ln -s /dev/urandom /dev/random
haveged 生成随机数

切换到12.04下之后通过apt-get install uuid-dev安装uuid之后，之前的代码中的uuid_generate,uuid_unparse函数在新的库中不存在了（和10.04中的uuid-dev不是同一个包），导致链接失败。
为了不改动原有自己已写好的程序，只有找原先的uuid lib。解决方案如下：
在中下载到util-linux_2.20.1.orig.tar.gz包，里面包含很多系统工具的目录，如包含libuuid目录。使用下面的方法安装uuid库（包括静态lib文件及动态链接文件）：
tar xzvf util-linux_2.20.1.orig.tar.gz
cd util-linux-2.20.1
./configure --without-ncurses
cd libuuid

wifi信道的知识：
http://blog.csdn.net/briant_ccj/article/details/50493872
http://blog.csdn.net/briant_ccj/article/details/50493872
可以看到，在2.4GHz频段，我国所提供的可用信道还是非常丰富的，在2.412-2.472GHz，共有13个信道可供选择。
再来看看5GHz频段，包含5150MHz-5825MHz的无线电频段，一共拥有201个信道，但能用的确实不多，特别是在我国，仅有5个信道（149,153,157,161,165）可用。考虑到信道就是无线数据的传输通道，也就是说，在人员密集的情况下，5个信道的体验效果肯定会受影响；不过目前来看，支持5GHz频段的设备并不多，因此目前还看不到影响（未来或许也会开放更多信道）。

如何添加Samba用户

Window系统连上我们的开发机Linux，自然需要在Samba里添加一个新用户。

linux-06bq:/usr/local/services/samba/bin # ./smbpasswd -a sunjing
New SMB password:
Retype new SMB password:
Failed to add entry for user sunjing.

百度给出的结论是”添加的Samba用户首先必须是Linux用户”，一下子豁朗开郎。

linux-06bq:/etc/samba # useradd sunjing
linux-06bq:/usr/local/services/samba/bin # ./smbpasswd -a sunjing
New SMB password:
Retype new SMB password:
Added user sunjing.

[root@localhost /]# yum install gcc
Loaded plugins: langpacks

One of the configured repositories failed (Fedora 21 - x86_64),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:

1. Contact the upstream for the repository and get them to fix the problem.

2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).

3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:

yum-config-manager --disable fedora

4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:

yum-config-manager --save --setopt=fedora.skip_if_unavailable=true

前提是，你的smb.conf配置没有错误。你再看一下有没有启动smb，network服务？或者，你有没有把你的linux防火墙关掉？删除你的iptables的防火墙规则：
iptables -F
再使一下。

把rom文件封装成iso镜像文件---------------------------------------------------------------------------其中装了两个yum install mkisofs

[root@localhost vetrix_1.5]#
[root@localhost vetrix_1.5]# ls
build engineSrc install_root kernel_48 openSource rootfs tools webSrc
[root@localhost vetrix_1.5]# cd tools/
[root@localhost tools]# ls
dtool
[root@localhost tools]# cd dtool/
[root@localhost dtool]# ls
mkdvd.sh putiso.exp Vetrix-DVD-x86_64 Vetrix-DVD-x86_64-7015_11104.iso
[root@localhost dtool]# cd Vetrix-DVD-x86_64/
[root@localhost Vetrix-DVD-x86_64]# ls
isolinux market vetrix_11104.rom
[root@localhost Vetrix-DVD-x86_64]# --------------------------------------------------------------然后把rom文件拷贝到这里
[root@localhost Vetrix-DVD-x86_64]# cd ..
[root@localhost dtool]# ls
mkdvd.sh putiso.exp Vetrix-DVD-x86_64 Vetrix-DVD-x86_64-7015_11104.iso
[root@localhost dtool]# ------------------------------------------------------------------------------最后执行mkdvd。sh

[root@localhost build]#
[root@localhost build]# ./cleanrom.sh 执行脚本删除rom文件，后make去编译

hostname - 用以显示或设置系统的主机名称。[1]

/wifi/status
/wifi/ssid
/wifi/password
/wifi/broadcastFlag
/wifi/channel
/wifi/hwmode
/wifi/bandwidth

ctrl + alt +. 重启

yum -y install gcc
wget
xz -d dnsmasq-2.76.tar.xz
tar xvf dnsmasq-2.76.tar
cd dnsmasq-2.76
make install

制作iso可启动U盘，用ULtraISO软件：打开iso文件（可替换rom文件）然后启动写入硬盘映像，ok

安装vetrix系统：响了之后按delete键(进不去修改putty的115200)进入bios（应该插上U盘自己进啊），配置pcI里面的SR-IOV（enable了）然后选择usb重启，就开始安装vetrix系统了，

adm admin@8888，格式化---------就可以按照文档来了；（把显示器键盘都插到设备上）

int getWifiChannel(void* data)
{

// range[i] = atoi(tmp);
}

return ret;
}

int getWifiMode(void* data)
{
int ret = 0;
FILE *pp = NULL;

BIOS里面把 VT-D （该选项需要硬件厂商在BIOS里面加上）打开，然后重启即可了。

如何让你的linux程序在后台静默执行？

#!/bin/bash
/usr/local/services/main &

执行脚本：
./run.sh &

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

CentOS 7的服务systemctl脚本存放在：/usr/lib/systemd/，有系统（system）和用户（user）之分，需要开机不登陆就能运行的程序，存在系统服务里，即：/usr/lib/systemd/system目录下
每一个服务以.service结尾，一般会分为3部分：[Unit]、[Service]和[Install]，我写的这个服务用于开机运行tomcat项目:
[plain] view plain copy
1.vim /usr/lib/systemd/system/tomcat.service
[plain] view plain copy
1.[Unit]
2.Description=tomcatapi
3.After=network.target
4.
5.[Service]
6.Type=forking
7.PIDFile=/usr/local/tomcat/tomcat.pid
8.ExecStart=/usr/local/tomcat/bin/startup.sh
9.ExecReload=
10.ExecStop=/usr/local/tomcat/bin/shutdown.sh
11.PrivateTmp=true
12.
13.[Install]
14.WantedBy=multi-user.target
[Unit]部分主要是对这个服务的说明，内容包括Description和After，Description用于描述服务，After用于描述服务类别;
[Service]部分是服务的关键，是服务的一些具体运行参数的设置，这里Type=forking是后台运行的形式，PIDFile为存放PID的文件路径，ExecStart为服务的运行命令，ExecReload为重启命令，ExecStop为停止命令，PrivateTmp=True表示给服务分配独立的临时空间，注意：[Service]部分的启动、重启、停止命令全部要求使用绝对路径，使用相对路径则会报错;
[Install]部分是服务安装的相关设置，可设置为多用户的
服务脚本按照上面编写完成后，以754的权限保存在/usr/lib/systemd/system目录下，这时就可以利用systemctl进行测试了
最后用以下命令将服务加入开机启动即可：
1.systemctl enable tomcat

sysctl命令
内核与模块管理
sysctl命令被用于在内核运行时动态地修改内核的运行参数，可用的内核参数在目录/proc/sys中。它包含一些TCP/ip堆栈和虚拟内存系统的高级选项，这可以让有经验的管理员提高引人注目的系统性能。用sysctl可以读取设置超过五百个系统变量。

systemctl 是管制服务的主要工具

设备里查看：
[root@localhost /]#
[root@localhost /]# ls lib/systemd/system/wifi-client.service
lib/systemd/system/wifi-client.service
[root@localhost /]#
[root@localhost /]# ls usr/lib/systemd/system/wifi-client.service

代码修改rootfs里内容：
[root@localhost /]# ls /lib/systemd/system/winbind.service
/lib/systemd/system/winbind.service
[root@localhost /]#

[Unit]
Description=--wifi--
After=virtd.service

[Service]
ExecStart=/software/bin/wifi_client
Restart=always
[Install]
WantedBy=multi-user.target

查询二: SELECT * FROM test WHERE data<>NULL

modprobe和insmod类似，都是用来动态加载驱动模块的，区别在于modprobe可以解决load module时的依赖关系，它是通过/lib/modules/#uname -r/modules.dep(.bb)文件来查找依赖关系的；而insmod不能解决依赖问题。
