chown命令的用法

chown命令的用法

chown命令的用法chown命令的用法chown将指定文件的拥有者改为指定的用户或组,用户可以是用户名或者用户id;组可以是组名或者组id;文件是以空格分开的要改变权限的文件列表,支持通配符。

系统管理员经常使用chown 命令,在将文件拷贝到另一个用户的名录下之后,让用户拥有使用该文件的权限。

1.命令格式:chown [选项]... [所有者][:[组]] 文件...2.命令功能:通过chown改变文件的拥有者和群组。

在更改文件的所有者或所属群组时,可以使用用户名称和用户识别码设置。

普通用户不能将自己的文件改变成其他的拥有者。

其操作权限一般为管理员。

3.命令参数:必要参数:-c 显示更改的部分的信息-f 忽略错误信息-h 修复符号链接-r 处理指定目录以及其子目录下的所有文件-v 显示详细的处理信息-deference 作用于符号链接的指向,而不是链接文件本身选择参数:--reference= 把指定的目录/文件作为参考,把操作的文件/目录设置成参考文件/目录相同拥有者和群组--from= 只有当前用户和群组跟指定的用户和群组相同时才进行改变--help 显示帮助信息--version 显示版本信息4.使用实例:实例1:改变拥有者和群组命令:chown mail:mail log2012.log输出:[root@localhost test6]# ll---xr--r-- 1 root users 302108 11-30 08:39 linklog.log ---xr--r-- 1 root users 302108 11-30 08:39 log2012.log -rw-r--r-- 1 root users 61 11-30 08:39 log2013.log-rw-r--r-- 1 root users 0 11-30 08:39 log2014.log-rw-r--r-- 1 root users 0 11-30 08:39 log2015.log-rw-r--r-- 1 root users 0 11-30 08:39 log2016.log-rw-r--r-- 1 root users 0 11-30 08:39 log2017.log[root@localhost test6]# chown mail:mail log2012.log [root@localhost test6]# ll---xr--r-- 1 root users 302108 11-30 08:39 linklog.log---xr--r-- 1 mail mail 302108 11-30 08:39 log2012.log -rw-r--r-- 1 root users 61 11-30 08:39 log2013.log-rw-r--r-- 1 root users 0 11-30 08:39 log2014.log-rw-r--r-- 1 root users 0 11-30 08:39 log2015.log-rw-r--r-- 1 root users 0 11-30 08:39 log2016.log-rw-r--r-- 1 root users 0 11-30 08:39 log2017.log [root@localhost test6]#说明:实例2:改变文件拥有者和群组命令:chown root: log2012.log输出:[root@localhost test6]# ll总计 604---xr--r-- 1 root users 302108 11-30 08:39 linklog.log ---xr--r-- 1 mail mail 302108 11-30 08:39 log2012.log -rw-r--r-- 1 root users 61 11-30 08:39 log2013.log-rw-r--r-- 1 root users 0 11-30 08:39 log2014.log-rw-r--r-- 1 root users 0 11-30 08:39 log2015.log-rw-r--r-- 1 root users 0 11-30 08:39 log2016.log-rw-r--r-- 1 root users 0 11-30 08:39 log2017.log [root@localhost test6]# chown root: log2012.log [root@localhost test6]# ll总计 604---xr--r-- 1 root users 302108 11-30 08:39 linklog.log ---xr--r-- 1 root root 302108 11-30 08:39 log2012.log -rw-r--r-- 1 root users 61 11-30 08:39 log2013.log-rw-r--r-- 1 root users 0 11-30 08:39 log2014.log-rw-r--r-- 1 root users 0 11-30 08:39 log2015.log-rw-r--r-- 1 root users 0 11-30 08:39 log2016.log-rw-r--r-- 1 root users 0 11-30 08:39 log2017.log [root@localhost test6]#说明:实例3:改变文件群组命令:chown :mail log2012.log输出:[root@localhost test6]# ll总计 604---xr--r-- 1 root users 302108 11-30 08:39 linklog.log ---xr--r-- 1 root root 302108 11-30 08:39 log2012.log -rw-r--r-- 1 root users 61 11-30 08:39 log2013.log-rw-r--r-- 1 root users 0 11-30 08:39 log2014.log-rw-r--r-- 1 root users 0 11-30 08:39 log2015.log-rw-r--r-- 1 root users 0 11-30 08:39 log2016.log-rw-r--r-- 1 root users 0 11-30 08:39 log2017.log [root@localhost test6]# chown :mail log2012.log [root@localhost test6]# ll总计 604---xr--r-- 1 root users 302108 11-30 08:39 linklog.log ---xr--r-- 1 root mail 302108 11-30 08:39 log2012.log -rw-r--r-- 1 root users 61 11-30 08:39 log2013.log-rw-r--r-- 1 root users 0 11-30 08:39 log2014.log-rw-r--r-- 1 root users 0 11-30 08:39 log2015.log-rw-r--r-- 1 root users 0 11-30 08:39 log2016.log-rw-r--r-- 1 root users 0 11-30 08:39 log2017.log说明:实例4:改变指定目录以及其子目录下的所有文件的拥有者和群组命令:chown -r -v root:mail test6输出:[root@localhost test]# lldrwxr-xr-x 2 root users 4096 11-30 08:39 test6[root@localhost test]# chown -r -v root:mail test6“test6/log2014.log”的所有者已更改为 root:mail“test6/linklog.log”的所有者已更改为 root:mail“test6/log2015.log”的所有者已更改为 root:mail“test6/log2013.log”的所有者已更改为 root:mail“test6/log2012.log”的所有者已保留为 root:mail“test6/log2017.log”的所有者已更改为 root:mail“test6/log2016.log”的所有者已更改为 root:mail“test6”的所有者已更改为 root:mail[root@localhost test]# lldrwxr-xr-x 2 root mail 4096 11-30 08:39 test6[root@localhost test]# cd test6[root@localhost test6]# ll总计 604---xr--r-- 1 root mail 302108 11-30 08:39 linklog.log ---xr--r-- 1 root mail 302108 11-30 08:39 log2012.log -rw-r--r-- 1 root mail 61 11-30 08:39 log2013.log-rw-r--r-- 1 root mail 0 11-30 08:39 log2014.log-rw-r--r-- 1 root mail 0 11-30 08:39 log2015.log-rw-r--r-- 1 root mail 0 11-30 08:39 log2016.log-rw-r--r-- 1 root mail 0 11-30 08:39 log2017.log。

linux mail 命令参数

linux mail 命令参数

linux mail 命令参数使用mail发邮件时,必须先将sendmail服务启动。

mail –s “邮件主题”–c”抄送地址”–b “密送地址” -- -f 发送人邮件地址–F 发件人姓名 < 要发送的邮件内容三种常用格式发信mail -s test yangfang@ #第一种方法,你可以把当前shell当成编辑器来用,编辑完内容后Ctrl-D结束echo “mail content”|mail -s test yangfang@ #第二种方法,我用的最多,可能是喜欢管道的缘故吧mail -s test yangfang@ < file #第三种方法,以file的内容为邮件内容发信指定特定的发送人:$ mail -s "just a test" 收信人邮箱地址 < 要发送的邮件内容文件 -- -f 发送人邮件地址 -F 发件人姓名。

效果是: 信件内容将发送给收信人邮箱,显示的发送人为发送人姓名<发送人邮件地址>,显示的内容为发送的邮件内容...包含命令执行结果的MAIL发送:echo -e `ls /tmp`|mail -s "test" fff@ < /tmp/dd.txt -- -f cc@ -F cci 忽略 tty 的中断讯号。

(interrupt)I 强迫设成互动模式。

(Interactive)v 列印出讯息,例如送信的地点、状态等等。

(verbose)n 不读入 mail.rc 设定档。

s 邮件标题。

c cc 抄送邮件地址。

b bcc密送邮件地址。

需要sendmail或postfix服务如果单纯的发文件文件可以用cat xxxx.txt |mail -s "主旨" abc@ fff@ 如果需要发送附件需要安装uuencode来编码 (yum install sharutils)单独发附件,这样xxxx@会收到一个data.txt的附件uuencode /tmp/data_process.log data.txt |mail xxx@如果需要正文和附件一起发:uuencode /tmp/data_process.log data.txt > /tmp/data_temp.txt系统收到邮件都会保存在“/var/spool/mail/[linux用户名]”文件中。

Java+Mail+Swing+SSL+Html+定时操作获取邮箱中的内容

Java+Mail+Swing+SSL+Html+定时操作获取邮箱中的内容

1)写程序用pop3收取gmail的邮件入口参数:用户名/ 密码做一个线程,每15分钟检查一次邮箱,收取邮箱的邮件,并解码后将标题显示出来请写出程序(提示:gmail的pop3使用SSL方式,网上有完整可运行的源程序。

注意是每15分钟,不是隔15分钟)1.程序1(based on jdk1.6, jboss java mail)import javax.mail.*;import javax.mail.internet.InternetAddress;import javax.mail.internet.MimeUtility;import javax.swing.*;import

e-mail常用的协议有

竭诚为您提供优质文档/双击可除e-mail常用的协议有篇一:internet技术snifferpro嗅探e-mail南京工程学院实验报告课程名称internet技术实验项目名称sniffer分析e-mail协议数据实验学生班级k软件131实验学生姓名徐智强学号240130529实验时间20xx.5.9实验地点信息楼专业机房实验成绩评定一、验目的和要求snifferpro协议分析器能获取在同一物理网络内的所有数据流量。

用sniffer分析器能获取e-mail协议数据,进行分析验证e-mail协议的命令及会话过程。

二、实验环境需装有snifferpro的一个物理网试验环境,其中有一台smtp服务器,snifferpro可运行在局域网的任何一台机器上,网络连接最好用hub且在一个子网,这样能抓到连到hub上每台机器传输的包。

版本是4.6,snifferpro软件安装非常简单,setup后一路确定即可,第一次运行时需要选择你的网卡。

、最后在win2000下运行,在win20xx下运行网络流量表有问题。

三、相关内容说明为实验方便起见,e-mail客户端用outlook,而smtp 服务器可用iis中自带的smtp服务器。

启动snifferpro,然后用outlook发送邮件,即可获取e-mail协议数据。

四、实验步骤1)首先打开outlookexpress,在上面的工具条里,找到工具菜单,点一下工具菜单,出来一系列的命令,点击一下账户。

如下图1。

图12)点击后,跳出来一个对话框,然后点击一下邮件的字样,右侧会有一个添加的按钮,点一下,又出现一个邮件的命令。

如下图2.图23)根据提示输入你的所用户名,如果没有重复的话,就会继续点下一步,接着会让你输入电子邮件地址,再点一下下一步。

如下图3.图34)又跳出一个新的命令条,这个时候,需要你输入pop 和smtp服务器的地址。

如下图4.图45)接着再点下一步,输入你的用户名和密码。

9、测试计划工作流(The Test Plan Workflow)对成功的应用程序测试来说,开发一个清晰并简明的测试计划是必要的基础。

一个好的测试计划,能够让你在整个测试过程的任何位置,对应用程序的质量进行评定。

本章描述了怎样使用TestDirector测试计划模块来开发测试计划。

开发一个测试计划包括如下步骤:9.1定义测试策略(Defining Testing Strategy)若想勾画一个测试策略,来达到定义在需求模块的测试需求,需要先问自己如下两个问题:你应当怎样测试你的应用程序?●你将使用哪些测试技术(压力测试、安全测试、性能和负载测试等等)?●你将怎样处理缺陷(缺陷严重等级、打开、关闭缺陷权限管理等)?你需要什么资源?●为了测试,你需要什么资源(人员、硬件等等)?●各个任务什么时候被完成?举个例子,假设一个航班预定软件,它能够让你去管理航班调动、旅客登记和机票销售。

此种情况下,手动测试和自动测试均需要。

你应该指派有编程经验的人设计自动测试,没有编程经验的人设计手动测试。

9.2定义测试主题(Defining Test Subjects)根据应该程序功能的等级关系,将应该程序功能分解为各个主题,并建造相应的表现应用程序功能的测试计划树。

测试计划树是你的测试计划的一种图形的表现。

它是根据主题组织的测试分级表,而每一个主题所包含的,就是为了实现质量要求而需要进行的测试。

例如,对于航班预定软件,你可以将Create Order、Delete Order、Open Order和Update Order 作为测试主题。

9.3设计测试(Planning Tests)为测试计划树上的每一个主题设计测试。

确定每各测试主题应该创建哪些种类的测试,如正规级别测试或回归测试。

然后在每个测试计划树的分支上创建并设计它们。

例如,在航班预定软件的Create Order测试主题下,可以包括如下的测试:Change Date、Change From Location、Change To Location、Insert New Order和Verify Insertion。

如何看懂电子邮件头

如何看懂电子邮件头
如何看懂电子邮件头
邮件头信息提供了详细的技术信息列表,如:该邮件的发件人、用于撰写该邮件的软件以及在其到达收件人途中所经过的电子邮件服务器。这些详细信息对于辨别电子邮件的问题或者辨别未经授权的商务邮件的来源非常有用。
首先,先向您介绍一下电子邮件头中的常见内容
我们以两名用户举例说明,一名用户的邮件地址是 test@,另一名用户的地址是 abc@(该用户使用 Outlook 2003)。让我们来看一下从 Abc 的帐户发送到Test的邮件。
这是在此邮件首次通过 Microsoft Exchange Server 时在此邮件上所加盖的时间戳。
由于 Internet 上未经授权的商业邮件数量已迅猛增长,因此在邮件头中提供虚假信息的行为也日益增长。这也称为欺骗。既发件人通过一些软件或者编程手法,随意修改邮件头中的信息。比如冒用他人域名以及账号,或者隐藏自己的域名等。另外,这些邮件往往是来自某种群发电子邮件服务(这种服务通过宣传方案的方式快速致富)。

3-发送邮件测试

3-发送邮件测试

1.首先在AD DC上面新建一个域用户帐号,我这里新建一个test@.这里我已经建好了,具体步骤就不多说了。

2.再进入exchange server,打开EMC控制台,我们在"recipient configuration"这里,右击选择"New mailbox".3.选择新建一个user mailbox,即用户邮箱。

当然也可以建立其它三种类型的邮箱。

room mailbox (会议室邮箱)这些邮箱是分配给会议地点(例如会议室、礼堂和培训室)的资源邮箱。

equipment mailbox(设备邮箱)这些邮箱是分配给非特定于位置的资源(例如便携式计算机投影仪、麦克风或是公司汽车)的资源邮箱。

Linked mailbox (链接邮箱)链接邮箱是由独立的受信任林中的用户访问的邮箱。

如果组织选择在资源林中部署 Exchange,则可能需要使用链接邮箱。

资源林方案使组织可以将 Exchange 集中在单个林中,同时允许使用一个或多个受信任林中的用户帐户访问Exchange 组织。

关于exchange server的详细收件人说明,请参照以下文档:/zh-cn/library/bb201680.aspx4. 我这里选择一个已经存在的用户,也就是我们刚刚新建好的test@。

5.选择这个用户test@6.好了,看到以下的选项。

这个alias,他的意思是别名,也就是邮箱的名称。

比方说我的邮箱别名是andy.gao,那么我新建好后的邮箱全名就是andy.gao@。

我这里还是使用test.7.好了,邮箱已经新建成功了,下面我们来用客户端测试一下发送邮件。

这里使用administrator邮箱给test用户发送邮件,可以看到,邮件可以收到了,成功了。

说明:本测试只是内部测试邮件,需要注意的地方有俩点,第一是新建邮箱的时候,有四种类型可取,用户可以根据自己的需要选择邮箱类型。

第二就是如果是测试接收外网邮件,需要建立相关的域名邮件MX记录。

M计划任务

M计划任务

计划任务先来看一下mail--用户邮件信箱用户邮箱放置的目录:/var/spool/mail/进入到mail收件箱之后可使用“?”来查看可以使用哪些命令d 删除后面接的信件号码,d10表示删除第10封邮件;d11-15表示删除第11至15封邮件。

如果要使删除生效的话还要结合“q”这个命令.s 将新建保存为文件。

如s 5 ~/mail.file表示将第5封新建保存到家目录下叫mail.file的文件中x 同exit。

不做任何操作离开mail程序。

不管你之前进行过任何删除的动作都不会生效q 离开mail程序。

会做两件事情:将刚才删除的新建移出mailbox;将刚才阅读过的信件存入~/mbox直接编辑邮件内容:[root@localhost ~]# mail -s "test" bob -->直接编写信件内容Hello,bobNice to meet you in the network.You are very nice.byebye!. -->这里是一个“.”符号Cc: liuds将文档内容输入到邮件中:[root@localhost ~]# mail -s "mailtest" bob < mailtest.txt -->将文件导入[root@localhost ~]# su - bob[bob@localhost ~]$ mailMail version 8.1 6/6/93.

linux搭建邮件服务器

linux搭建邮件服务器

linux搭建邮件服务器邮件服务器概述使⽤Email很容易,但是Internet的邮件系统是通过很复杂的⼏个系统组成的,对于最终⽤户⽽⾔,我们熟悉的Outlook,Foxmail等都是⽤来收信和发信的,称之为MUA:Mail User Agent,邮件⽤户代理。

MUA并⾮直接将邮件发送⾄收件⼈⼿中,⽽是通过MTA:Mail Transfer Agent,邮件传输代理代为传递,Sendmail和Postfix就是扮演MTA 的⾓⾊。

⼀封邮件从MUA发出后,可能通过⼀个或多个MTA传递,最终到达MDA:Mail Delivery Agent,邮件投递代理,邮件到达MDA后,就存放在某个⽂件或特殊的数据库⾥,我们将这个长期保存邮件的地⽅称之为邮箱。

⼀旦邮件到达邮箱,就原地不动了,等⽤户再通过MUA将其取⾛,就是⽤Outlook,Foxmail等软件收信的过程。

所以⼀封邮件的流程是:发件⼈:MUA --发送–> MTA -> 若⼲个MTA… -> MTA -> MDA <–收取-- MUA:收件⼈协议:MUA到MTA,以及MTA到MTA之间使⽤的协议就是SMTP协议,⽽收邮件时,MUA到MDA之间使⽤的协议最常⽤的是POP3或IMAP。

如何进行MD5验证?篇一:MD5验证是什么?MD5验证是什么?从通俗的话讲---就好比每个人的指纹都是唯一的一样,文件的MD5值也是唯一的,效验MD5就是用来确保文件在传输过程中未被修改用的.从专业的话解释----一个 MD5 校验通过对接收的传输数据执行散列运算来检查数据的正确性.计算出的散列值拿来和随数据传输的散列值比较.如果两个值相同,说明传输的数据完整无误.没有被窜改过(前提是散列值没有被窜改),从而可以放心使用.MD5校验可以应用在多个领域,比如说机密资料的检验,下载文件的检验,明文密码的加密等MD5校验原理举例说明:如客户往我们数据中心同步一个文件,该文件使用MD5校验,那么客户在发送文件的同时会再发一个存有校验码的文件,我们拿到该文件后做MD5运算,得到的计算结果与客户发送的校验码相比较,如果一致则认为客户发送的文件没有出错,否则认为文件出错需要重新发送.篇二:发送验证邮件的三种方法在.NET中的System.Web.Mail名字空间下,有一个专门使用SMTP协议来发送邮件的类:SmtpMail,它已能满足最普通的发送邮件的需求.这个类只有一个自己的公共函数--Send()和一个公共属性—SmtpServer您必须通过SmtpServer属性来指定发送邮件的服务器的名称(或IP地址),然后再调用 Send()函数来发送邮件.第二.使用CDO组件发送邮件CDO是Collaboration Data Objects的简称,它是一组高层的COM对象集合,并经历了好几个版本的演化,现在在Windows_和E_change_中使用的都是CDO2.0的版本(分别为cdosys.dll和cdoe_.dll).CDOSYS构建在SMTP协议和NNTP 协议之上,并且作为Windows_ Server的组件被安装,您可以在系统目录(如c:\winnt或c:\windows)的system32子目录中找到它(cdosys.dll).CDO组件相对于先前介绍的SmtpMail对象功能更为丰富,并提供了一些SmtpMail类所没有提供的功能,如通过需要认证的SMTP服务器发送邮件等.下面一段代码就展示了如何使用CDO组件通过需要认证的SMTP服务器发送邮件的过程:(in C_)public void CDOsendMail(){try{CDO.Message oMsg = new CDO.Message();oMsg.From = myaccount@oMsg.To = myaccount@oMsg.Subject = MailTestoMsg.HTMLBody = html body Test /body /htmlCDO.IConfiguration iConfg = oMsg.Configuration;ADODB.Fields oFields = iConfg.Fields;oFields[ /cdo/configuration/sendusing ].V alue=2;oFields[ /cdo/configuration/sendemailaddr ess ].Value= myaccount@ //sender mailoFields[ /cdo/configuration/smtpaccountna me ].Value= myaccount@ //email accountoFields[ /cdo/configuration/sendusername ].Value= username oFields[ /cdo/configuration/sendpassword ].Value= passwordoFields[ /cdo/configuration/smtpauthentic ate ].Value=1; //value=0 代表Anonymous验证方式(不需要验证)//value=1 代表Basic验证方式(使用basic (clear-te_t) authentication. //The configuration sendusername/sendpassword or postusername/postpassword fields are used tospecify credentials.)//Value=2 代表NTLM验证方式(Secure Password Authentication in Microsoft Outlook E_press)oFields[ /cdo/configuration/languagecode ].Value=0___;oFields[ /cdo/configuration/smtpserver ]. Value= smtp._oFields.Update();oMsg.BodyPart.Charset= gb23_oMsg.HTMLBodyPart.Charset= gb23_oMsg.Send();oMsg = null;}catch (E_ception e){throw e;}}注意:由于E_change_的CDO组件cdoe_.dll会更新原有的Windows_的CDO 组件cdosys.dll,所以如果您希望继续使用cdosys.dll,您必须先通过regsrv32.e_e卸载掉cdoe_.dll.第三.使用Socket撰写邮件发送程序当然,如果您觉得SmtpMail不能满足您的需求,CDO又不够直截了当,那就只能自己动手了;其实如果您很熟悉Socket编程,自己写一个发送邮件的程序并不很难,以下就是一个例子.首先,我们简单介绍一下带验证的SMTP服务器如何使用AUTH原语进行身份验证,其详细的定义可以参考RFC2554.具体如下:1)首先,需要使用EHLO而不是原先的HELO.2)EHLO成功以后,客户端需要发送AUTH原语,与服务器就认证时用户名和密码的传递方式进行协商.3)如果协商成功,服务器会返回以3开头的结果码,这是就可以把用户名和密码传给服务器.4)最后,如果验证成功,就可以开始发信了.下面是一个实际的例子,客户端在Win_P的Command窗口中通过 telnet 25 命令连接到263的smtp服务器发信:2_ Welcome to coremail System(With Anti-Spam) 2.1EHLO 250-_2._8.30.29250-PIPELINING250-SIZE 1_4__250-ETRN250-AUTH LOGIN250 8BITMIMEAUTH LOGIN334 V_Nlcm5hbWU6b_lhY2NvdW50334 UGFzc3dvcmQ6b_lwY_Nzd29yZA==235 Authentication successfulMAIL FROM:myaccount@250 OkRCPT TO:myaccount@250 OkData354 End data with CR LF . CR LFThis is a testing email.haha..250 Ok: queued as AC5291D64_C4QUIT2_ Bye上面的内容就是发信的全过程.其中与身份验证有关的主要是第九到第十四行: AUTH LOGIN 客户端输入334 V_Nlcm5hbWU6 服务器提示〝Username:=b_lhY2NvdW50 客户端输入〝myaccount= 的Base64编码334 UGFzc3dvcmQ6 服务器提示〝Password:=b_lwY_Nzd29yZA== 客户端输入〝mypassword= 的Base64编码235 Authentication successful 服务器端通过验证从上面的分析可以看出,在这个身份验证过程中,服务器和客户端都直接通过Socket传递经过标准Base64编码的纯文本.这个过程可以非常方便的用C_实现,或者直接添加到原有的源代码中.另外,有些ESMTP服务器不支持AUTH LOGIN方式的认证,只支持AUTH CRAM-MD5方式验证.但是这两者之间的区别只是文本的编码方式不同.实现此功能的源代码可以在 /projects/opensmtp-net/ 上找到下载.下面给出了一个简单的伪码:public void SendMail(MailMessage msg){NetworkStream nwstream = GetConnection();WriteToStream(ref nwstream, EHLO + smtpHost + \r\nstring welcomeMsg = ReadFromStream(ref nwstream);// implement HELO command if EHLO is uecognized.if (IsUnknownCommand(welcomeMsg)){WriteToStream(ref nwstream, HELO + smtpHost + \r\n}CheckForError(welcomeMsg, ReplyConstants.OK);// Authentication is used if the u/p are suppliedAuthLogin(ref nwstream);WriteToStream(ref nwstream, MAIL FROM: + msg.From.Address + \r\n CheckForError(ReadFromStream(ref nwstream), ReplyConstants.OK);SendRecipientList(ref nwstream, msg.To);SendRecipientList(ref nwstream, );SendRecipientList(ref nwstream, msg.BCC);WriteToStream(ref nwstream, DATA\r\nCheckForError(ReadFromStream(ref nwstream), ReplyConstants.START_INPUT);if ( != null .Length != 0){ WriteToStream(ref nwstream, Reply-To: \ + + \ + msg.ReplyTo.Address + \r\n }else{ WriteToStream(ref nwstream, Reply-To: + msg.ReplyTo.Address + \r\n } if ( != null .Length != 0){ WriteToStream(ref nwstream, From: \ + + \ + msg.From.Address + \r\n }else{ WriteToStream(ref nwstream, From: + msg.From.Address + \r\n }WriteToStre篇三:单片机常用校验方法常见校验算法一.校验算法奇偶校验(单字节奇偶校验和多字节奇偶校验)MD5校验求校验和BCC(Block Check Character/信息组校验码),常说的异或校验方法CRC(Cyclic Redundancy Check/循环冗余校验)LRC(Longitudinal Redundancy Check/纵向冗余校验)二.奇偶校验内存中最小的单位是比特,也称为〝位〞,位有只有两种状态分别以1和0来标示,每8个连续的比特叫做一个字节(byte).不带奇偶校验的内存每个字节只有8位,如果其某一位存储了错误的值,就会导致其存储的相应数据发生变化,进而导致应用程序发生错误.而奇偶校验就是在每一字节(8位)之外又增加了一位作为错误检测位.在某字节中存储数据之后,在其8个位上存储的数据是固定的,因为位只能有两种状态1或0,假设存储的数据用位标示为1.1. 1.0.0.1.0.1,那么把每个位相加(1+1+1+0+0+1+0+1=5),结果是奇数,那么在校验位定义为1,反之为0.当CPU读取存储的数据时,它会再次把前8位中存储的数据相加,计算结果是否与校验位相一致.从而一定程度上能检测出内存错误,奇偶校验只能检测出错误而无法对其进行修正,同时虽然双位同时发生错误的概率相当低,但奇偶校验却无法检测出双位错误三.MD5校验MD5的全称是Message-Digest Algorithm 5,在90年代初由MIT的计算机科学实验室和RSA Data Security Inc 发明,由 MD2/MD3/MD4 发展而来的.MD5的实际应用是对一段Message(字节串)产生fingerprint(指纹),可以防止被〝篡改〞.举个例子,天天安全网提供下载的MD5校验值软件WinMD5.zip,其MD5值是1e_ab3591d25583eff5_9293dc98d2,但你下载该软件后计算MD5 发现其值却是8_95f50b94bb4891a4ce4ffb6ccf64b,那说明该ZIP已经被他人修改过,那还用不用该软件那你可自己琢磨着看啦.四.求校验和求校验和其实是一种或运算.如下://-------------------------------------------------------------------------------------------------- //如下是计算校验位函数// checkdata,包括起始位在内的前九位数据的校验和//-------------------------------------------------------------------------------------------------- unsigned char CLU_checkdata(void){ //求校验和unsigned char checkdata=0;for(point=0;point 9,TI=1;point++){checkdata=checkdata | buffer[point];}return(checkdata);}四.BCC(Block Check Character/信息组校验符号)BCC校验其实是奇偶校验的一种,但也是经常使用并且效率较高的一种,所谓BCC校验法(block check character),就是在发送前和发送后分别把BCC以前包括ET_字符的所有字符按位异或后,按要求变换(增加或前去一个固定的值)后所得到的字符进行比较,相等即认为通信无错误,不相等则认为通信出错.非接触卡读卡器与PC机的通讯格式如下:ST_(_H)+ 6个字节的卡号+VERH+VERL+EOT(_H)ST_(_H)起始字节EOT(_H)结束字节6个字节的卡号为六个十六进制的ASCII字符,6个字节的传送,高字节在前,低字节在后.例如:卡号:8 D E F 9 E传输的数据格式:38 44 45 46 39 45(十六进制)在校验时采用目前最通用的BCC校验方式:具体的方法是:将有效的卡号接字节作异或(_OR)校验:38H (_OR)44H (_OR)45H (_OR)46H (_OR)39H(_OR)45H =_H 然后将接收到的数据VERH+VERL合成一个字节数据,30H(HE_)=0,33H(HE_)=3 合成数据为_H,接收到的数据与我们收到的卡号的校验数据一致,则接收到的卡号为正确卡号.再比如现有卡号为:卡号:0 5 8 E 4 2传输的数据格式:30 35 38 45 34 32 (十六进制)在校验时采用目前最通用的BCC校验方式:具体的方法是:将有效的卡号接字节作异或(_OR)校验:30H (_OR)35H (_OR)38H (_OR)45H (_OR)34H(_OR)32H =7EH 然后将接收到的数据VERH+VERL合成一个字节数据,37H(HE_)=7,45H(HE_)=E 合成数据为7EH,接收到的数据与我们收到的卡号的校验数据一致,则接收到的卡号为正确卡号.在编写程序时,可以先将所有数据都接收到计算机的内存中,然后计算BCC校验值VALUE1,再将接收的BCC值拼成一个十六进制数VALUE2,然后比较这两个值,如果相等,则接收到的卡号为合法卡号,然后按您的系统作相应的处理.VB代码如下:Public Function bcc(a As String) As StringDim b As Integerb = 0For i = 1 To Len(a) Step 2b = b _or ( h + Mid(a, i, 2))Ne_tb = b And HFFIf b _ Thenbcc = 0 + He_(b)Elsebcc = He_(b)End IfEnd Function五.CRC(Cyclic Redundancy Check/循环冗余校验)CRC 校验的基本思想是利用线性编码理论,在发送端根据要传送的k位二进制码序列,以一定的规则产生一个校验用的监督码(既CRC码)r位,并附在信息后边,构成一个新的二进制码序列数共(k+r)位,最后发送出去.在接收端,则根据信息码和CRC码之间所遵循的规则进行检验,以确定传送中是否出错._位的CRC码产生的规则是先将要发送的二进制序列数左移_位(既乘以)后,再除以一个多项式,最后所得到的余数既是CRC码.它是利用除法及余数的原理来作错误侦测(Error Detecting)的.实际应用时,发送装置计算出CRC值并随数据一同发送给接收装置,接收装置对收到的数据重新计算CRC并与收到的CRC相比较,若两个CRC值不同,则说明数据通讯出现错误.根据应用环境与习惯的不同,CRC又可分为以下几种标准:①CRC-_码;②CRC-_码;③CRC-CCITT码;④CRC-32码.CRC-_码通常用来传送6-bit字符串.CRC-_及CRC-CCITT码则用是来传送8-bit字符,其中CRC-_为美国采用,而CRC-CCITT为欧洲国家所采用.CRC-32码大都被采用在一种称为Point-to-Point的同步传输中.下面为CRC计算过程:1.设置CRC寄存器,并给其赋值FFFF(he_).2.将数据的第一个8-bit字符与_位CRC寄存器的低8位进行异或,并把结果存入CRC寄存器.3.CRC寄存器向右移一位,MSB补零,移出并检查LSB.4.如果LSB为0,重复第三步;若LSB为1,CRC寄存器与多项式码相异或.5.重复第3与第4步直到8次移位全部完成.此时一个8-bit数据处理完毕. 6.重复第2至第5步直到所有数据全部处理完成.7.最终CRC寄存器的内容即为CRC值.常用的CRC循环冗余校验标准多项式如下:CRC(_位) = __+__+_2+1CRC(CCITT) = __+__ +_5+1CRC(32位) = _32+_26+_23+__+__+__+__+_8+_7+_5+_4+_2+_+1 以CRC(_位)多项式为例,其对应校验二进制位列为1 1_0 __ __ __. CRC基本原理是:在K位信息码后再拼接R位的校验码,整个编码长度为N位,因此,这种编码又叫(N,K)码.对于一个给定的(N,K)码,可以证明存在一个最高次幂为N-K=R的多项式G(_),根据G(_)可以生成K位信息的校验码,而G(_)叫做这个CRC 码的生成多项式.校验码的具体生成过程为:假设发送信息用信息多项式C(_)表示,将C(_)左移R位,则可表示成C(_)_2R,这样C(_)的右边就会空出R位,这就是校验码的位置.通过C(_)_2R除以生成多项式G(_)得到的余数就是校验码.几个基本概念1.多项式与二进制数码多项式和二进制数有直接对应关系:_的最高幂次对应二进制数的最高位,以下各位对应多项式的各幂次,有此幂次项对应1,无此幂次项对应0.可以看出:_的最高幂次为R,转换成对应的二进制数有R+1位.多项式包括生成多项式G(_)和信息多项式C(_).如生成多项式为G(_)=_4+_3+_+1, 可转换为二进制数码__1.而发送信息位 __,可转换为数据多项式为C(_)=_3+_2+_+1.2.生成多项式是接受方和发送方的一个约定,也就是一个二进制数,在整个传输过程中,这个数始终保持不变.在发送方,利用生成多项式对信息多项式做模2除生成校验码.在接受方利用生成多项式对收到的编码多项式做模2除检测和确定错误位置.应满足以下条件:a.生成多项式的最高位和最低位必须为1.b.当被传送信息(CRC码)任何一位发生错误时,被生成多项式做模2除后应该使余数不为0.c.不同位发生错误时,应该使余数不同.d.对余数继续做模2除,应使余数循环.将这些要求反映为数学关系是比较复杂的.但可以从有关资料查到常用的对应于不同码制的生成多项式如图9所示:N K 码距d G(_)多项式 G(_)7 4 3 _3+_+1 1_17 4 3 _3+_2+1 __7 3 4 _4+_3+_2+1 _1_7 3 4 _4+_2+_+1 1___ _ 3 _4+_+1 1___ 7 5 _8+_7+_6+_4+_____3_6 3 _5+_2+__1_3_1 5 __+_9+_8+_6+_5+_3+1 _1_1__16357 3 _6+_+1 1___6351 5 __+__+_5+_4+_2+1 1______1_1 1_4 __+__+_2+1 _______1_3.模2除(按位除)模2除做法与算术除法类似,但每一位除(减)的结果不影响其它位,即不向上一位借位.所以实际上就是异或.然后再移位移位做下一位的模2减.步骤如下:a.用除数对被除数最高几位做模2减,没有借位.b.除数右移一位,若余数最高位为1,商为1,并对余数做模2减.若余数最高位为0,商为0,除数继续右移一位.c.一直做到余数的位数小于除数时,该余数就是最终余数.CRC校验程序编写:编写CRC校验程序有两种办法:一种为计算法,一种为查表法.下面对两种方法分别讨论.①计算法计算法就是依据CRC校验码的产生原理来设计程序.其优点是模块代码少,修改灵活,可移植性好.其缺点为计算量大.为了便于理解,这里假定了三位数据,而多项式码为A_1(he_).在窗体上放置一命令按钮Command1,并添加如下代码:Private Sub Command1_Click()Dim CRC() As ByteDim d() As Byte 待传输数据ReDim d(2) As Byted(0) = _3d(1) = _2d(2) = _5CRC = CRC_(d) 调用CRC_计算函数CRC(0)为高位CRC(1)为低位End Sub注意:在数据传输时CRC的低位可能在前,而高位在后.Function CRC_(data() As Byte) As StringDim CRC_Lo As Byte, CRC_Hi As Byte CRC寄存器Dim CL As Byte, CH As Byte 多项式码 HA_1Dim SaveHi As Byte, SaveLo As ByteDim i As IntegerDim Flag As IntegerCRC_Lo = HFFCRC_Hi = HFFCL = H1 多项式码低位 H_CH = HA0 多项式码高位 HA0For i = 0 To UBound(data)CRC_Lo = CRC_Lo _or data(i) 每一个数据与CRC寄存器进行异或For Flag = 0 To 7SaveHi = CRC_HiSaveLo = CRC_LoCRC_Hi = CRC_Hi \ 2 高位右移一位CRC_Lo = CRC_Lo \ 2 低位右移一位If ((SaveHi And H1) = H1) Then 如果高位字节最后一位为1CRC_Lo = CRC_Lo Or H80 则低位字节右移后前面补1End If 否则自动补0If ((SaveLo And H1) = H1) Then 如果LSB为1,则与多项式码进行异或CRC_Hi = CRC_Hi _or CHCRC_Lo = CRC_Lo _or CLEnd IfNe_t Flag。
