mysql的表crashed后修复
mysql的表在大量访问和写入环境下有可能损坏，报错如下：
在ubuntu8.10中，mysql的数据存放的路径在/var/lib/mysql,加入有个数据库叫snort，snort中有个表acid_event损坏了,那么在/var/lib/mysql/snort/下有个文件叫acid_event.MYI,修复办法是
如果你怀疑表的索引文件(*.MYI)发生了不可修 复的错误，甚至是丢失了这个文件，你可以使用数据文件(*.MYD)和数据格式文件(*.frm)重新生成它。首先制作一个数据文件 (tblName.MYD)的拷贝。重启你的MySQL服务并连接到这个服务上，使用下面的命令删除表的内容：
mysql> DELETE FROM tblName;
在 删除表的内容的同时，会建立一个新的索引文件。退出登录并重新关闭服务，然后用你刚才保存的数据文件(tblName.MYD)覆盖新的(空)数据文件。 最后，使用myisamchk执行标准的修复(上面的第二种方法)，根据表的数据的内容和表的格式文件重新生成索引数据。
shell> myisamchk --silent --force --fast --update-state \
-O key_buffer=64M -O sort_buffer=64M \
-O read_buffer=1M -O write_buffer=1M \
/path/to/datadir/*/*.MYI

ERROR 144 (HY000): Table './snort/acid_event' is marked as crashed and last (automatic?) repair failed解决办法是用myisamchk命令进行修复。
在ubuntu8.10中，mysql的数据存放的路径在/var/lib/mysql,加入有个数据库叫snort，snort中有个表acid_event损坏了,那么在/var/lib/mysql/snort/下有个文件叫acid_event.MYI,修复办法是
cd /var/lib/mysql/snort/错误产生原因，有人说是频繁查询和更新表造成的索引错误。还有说法为是MYSQL数据库因为某种原因而受到了损坏，如：数据库服务器突发性的断电、在提在数据库表提供服务时对表的原文件进行某种操作都有可 能导致MYSQL数据库表被损坏而无法读取数据。总之就是因为某些不可测的问题造成表的损坏。
myisamchk -c -r acid_event.MYI
当你试图修复一个被破坏的表的问题时，有三种修复类型。如果你得到一个错误信息指出一个临时文件不能建立，删除信息所指出的文件并再试一次--这通常是上一次修复操作遗留下来的。
这三种修复方法如下所示：
% myisamchk --recover --quick /path/to/tblName
% myisamchk --recover /path/to/tblName
% myisamchk --safe-recover /path/to/tblName
第一种是最快的，用来修复最普通的问题；而最后一种是最慢的，用来修复一些其它方法所不能修复的问题。
如果上面的方法无法修复一个被损坏的表，在你放弃之前，你还可以试试下面这两个技巧：如果你怀疑表的索引文件(*.MYI)发生了不可修 复的错误，甚至是丢失了这个文件，你可以使用数据文件(*.MYD)和数据格式文件(*.frm)重新生成它。首先制作一个数据文件 (tblName.MYD)的拷贝。重启你的MySQL服务并连接到这个服务上，使用下面的命令删除表的内容：
mysql> DELETE FROM tblName;
在 删除表的内容的同时，会建立一个新的索引文件。退出登录并重新关闭服务，然后用你刚才保存的数据文件(tblName.MYD)覆盖新的(空)数据文件。 最后，使用myisamchk执行标准的修复(上面的第二种方法)，根据表的数据的内容和表的格式文件重新生成索引数据。
如果你的表的格式文件(tblName.frm)丢失了或者是发生了不可修复的错误，但是你清楚如何使用相应的CREATE TABLE语句来重新生成这张表，你可以重新生成一个新的.frm文件并和你的数据文件和索引文件(如果索引文件有问题，使用上面的方法重建一个新的)一 起使用。首先制作一个数据和索引文件的拷贝，然后删除原来的文件(删除数据目录下有关这个表的所有记录)。
启动MySQL服务并使用当初的CREATE TABLE文件建立一个新的表。新的.frm文件应该可以正常工作了，但是最好你还是执行一下标准的修复(上面的第二种方法)。
快速检查和修复表：shell> myisamchk --silent --force --fast --update-state \
-O key_buffer=64M -O sort_buffer=64M \
-O read_buffer=1M -O write_buffer=1M \

修改默认的HTTP Response Header
黑客通常通过获取一个HTTP Response，然后解析出HTTP Response Header来知道对方用的是什么web 服务器软件，如下：
对于Tomcat,Header一般会暴露如下信息:
Server: Apache-Coyote/1.1
修改是在conf/server.xml,在Connector 元素中设置server属性即可。如下：
对于apache呢？
只要在httpd.conf中配上如下两个参数：
对于IIS来说有一个工具（URLScan）可以用来修改这个HTTP Response Header，让黑客得到假的Header信息，URLScan的地址：http://learn.iis.net/page.aspx/473/using-urlscanHTTP/1.1 200 OK
Server: Microsoft-IIS/5.0

Go figure
Example 1:Ironically, when asked about improvement, both parties indicated
that they thought communication should be more intense. Go figure!
Example 2: The prepositions are strangely the last thing almost all the children learn in a language. Go figure!
Example 3: Women and children are the first targets of war. Go figure.
Example 4: Go figure: Weight loss is one of the worst reasons for exercise.
Now, if your definitions of "go figure" run along the lines of "wow, isn't that right?" or "who'd have thought?" or "how come", they're all correct.
Think of "go figure" as short for "go and figure it out for yourself". It is used more like an exclamation, though, punctuating an unexpected fact. Oh yeah, that's right.

甲骨文74亿美元收购Sun
甲骨文周一（09-4-20）宣布，将以每股9.5美元的价格收购Sun，这一价格比Sun上周五收盘价高出了42%。包括Sun的现金和债务在内，该交易的价值为74亿美元。
如果此次交易顺利达成，则Sun将成为甲骨文自2005年1月以来的第52个收购对象。其中最大的几次并购分别是：2005年初，甲骨文以103亿美元收购全球第二大客户关系管理软件厂家仁科(PeopleSoft)；2007年以33亿美元收购商业情报软件厂家海波龙(Hyperion)；2008年初，以85亿美元收购中间件巨头BEA。

而甲骨文的收入也迅速膨胀。2004财年甲骨文总收入102亿美元，实现净利润27亿美元，2008财年总收入224亿美元，实现净利润55亿美元。
Sun今年1月份发布第二财季财报时表示，软件业务营收增长了21%，增幅似乎不小，但软件业务年营收仅为6亿美元。分析师预计今年Sun营收将达到124亿美元。Sun从本质上来说是一家硬件公司，这也是分析师预计其本财年将会亏损的原因。Sun各项业务并入甲骨文后，甲骨文将有能力向全球企业用户提供包括硬件、软件和技术支持在内的一店式整体解决方案。
立此存照。Lenny中用LVM调整磁盘卷大小
最近报/root分区磁盘不足，有幸是在安装系统时采用了LVM,否则问题就难解决了。
最初的分区：
现在要压缩myserver-home ,增加myserver-root。
查看物理卷
#pvdisplay
略……
查看卷组
#vgdisplay
略……
查看逻辑卷
#lvdisplay
确定要变更的两个逻辑卷名：
/dev/myserver/home 挂载点是 /home
/dev/myserver/root 挂载点是 /
(一)减少/dev/myserver/home
#umount /home
#mke2fs -n /dev/myserver/home
执行这个命令是要计算调整块的最终大小。我要将/dev/myserver/home减少到50G,而将腾出的空间给/dev/myserver/root.
上面的数据显示，每块大小为4096Bytes ，总共有74249216块。
50G=53687091200 Bytes =13107200 blocks
减少的块数=74249216 - 13107200=61142016
减少的61142016块= 238836M
#resize2fs -f /dev/myserver/home 13107200
#lvreduce -L-238836M /dev/myserver/home
#mount /home
检查是否减少了
#df -lh
(二)扩展/dev/myserver/root 的大小
#lvextend -L+238836M /dev/myserver/root
注意，这里在其他某些linux系统本可以执行ext2online 来实现，但是Lenny中没有这个命令，本应该用
#resize2fs /dev/myserver/root
检查是否增加了

Locard's Exchange Principle
On a live system, changes will occur simply due to the passage of time, as processes work, as data is saved and deleted, as network connections time out or are created, and so on. Some changes happen when the system just sits there and runs. Changes also occur as the investigator
runs programs on the system to collect information, volatile or otherwise. Running a program causes information to be loaded into physical memory, and in doing so, physical memory used by other, already running processes may be written to the page file. As the investigator collects information and sends it off the system, new network connections will be created. All these changes can be collectively explained by Locard’s Exchange Principle.
In the early 20th century, Dr. Edmond Locard’s work in the area of forensic science
and crime scene reconstruction became known as Locard’s Exchange Principle.
This principle states, in essence, that when two objects come into contact, material is
exchanged or transferred between them. If you watch the popular CSI crime show
on TV, you’ll invariably hear one of the crime scene investigators refer to possible
transfer.This usually occurs after a car hits something or when an investigator examines
a body and locates material that seems out of place.
Edmond Locard (1877–1966) studied law at the Institute of Legal Medicine and worked subsequently as an assistant to the forensic pioneer Alexandre Lacassagne prior to directing the forensic laboratory in Lyon, France. Locard's techniques proved useful to the French Secret Service during World War I (1914–1918), when Locard was able to determine where soldiers and prisoners had died by examining the stains on their uniforms.
Like Hans Gross and Alphonse Bertillon before him, Locard advocated the application of scientific methods and logic to criminal investigation and identification. Locard's work formed the basis for what is widely regarded as a cornerstone of the forensic sciences, Locard's Exchange Principle, which states that with contact between two items, there will be an exchange. It was Locard's assertion that when any person comes into contact with an object or another person, a cross-transfer of physical evidence occurs. By recognizing, documenting, and examining the nature and extent of this evidentiary exchange, Locard observed that criminals could be associated with particular locations, items of evidence, and victims. The detection of the exchanged materials is interpreted to mean that the two objects were in contact. This is the cause and effect principle reversed; the effect is observed and the cause is concluded.
Crime reconstruction involves examining the available physical evidence, those materials left at or removed from the scene, victim, or offender, for example hairs, fibers, and soil, as well as fingerprints, footprints, genetic markers (DNA), or handwriting. These forensically established contacts are then considered in light of available and reliable witness, the victim, and a suspect's statements. From this, theories regarding the circumstances of the crime can be generated and falsified by logically applying the information of the established facts of the case.
Locard's publications make no mention of an "exchange principle," although he did make the observation "Il est impossible au malfaiteur d'agir avec l'intensité que suppose l'action criminelle sans laisser des traces de son passage." (It is impossible for a criminal to act, especially considering the intensity of a crime, without leaving traces of this presence.). The term "principle of exchange" first appears in Police and Crime-Detection, in 1940, and was adapted from Locard's observations.

Open Source ETL (Extraction, Transform, Load) Written in Java[收藏]
- Octopus
- Octopus is a simple Java-based Extraction, Transform, and Loading (ETL) tool. It may connect to any JDBC data sources and perform transformations defined in an XML file. A loadjob-generator is provided to generate Octopus loadjob skeletons from an existing database. Many different types of databases can be mixed (MSSQL, Oracle, DB2, QED, JDBC-ODBC with Excel and Access, MySQL, CSV-files, XML-files,...) Three special JDBC drivers come with Octopus to support JDBC access to CSV-files (CSV-JDBC), MS-SQL (FreeTDS) and XML. Octopus supports Ant and JUnit to create a database / tables and extract/load data during a build or test process. - Xineo - Xineo XIL (XML Import Langage) defines an XML language for transforming various record-based data sources into XML documents, and provides a fully functional XIL processing implementation. This implementation has built-in support for relational (via JDBC) and structured text (like CSV) sources, and is extensible thanks to its public API, allowing dynamic integration of new data source implementations. It also provides an abstraction over output format, and the Xineo implementation can generate output documents into stream or as DOM document. Xineo's implementation built-in data sources include : Relational data via JDBC and Structured text via regular expressions.
- CloverETL - CloverETL Features include internally represents all characters as 16bit, converts from most common character sets (ASCII, UTF-8, ISO-8859-1,ISO-8859-2, etc), works with delimited or fix-length data records, data records (fields) are internally handled as a variable-length data structures, fields can have default values, handles NULL values, cooperates with any database with JDBC driver, transforming of the data is performed by independent components, each running as an independent thread, framework implements so called pipeline-parallelism, metadata describing structure of data files (records) can be read from XML and transformation graphs can be read from XML
- BabelDoc - BabelDoc is a Java framework for processing documents in linear stages, it tracks documents and can reintroduce documents back into into the pipelines, it is monitorable and configurable through a number of interfaces, it can be run standalone, in server processes or in application servers, it can be reconfigured dynamically by text files and database tables.
- Joost - Java implementation of the Streaming Transformations for XML (STX) language. Streaming Transformations for XML (STX) is a one-pass transformation language for XML documents. STX is intended as a high-speed, low memory consumption alternative to XSLT. Since it does not require the construction of an in-memory tree, it is suitable for use in resource constrained scenarios.
- CB2XML - CB2XML (CopyBook to XML) is a COBOL CopyBook to XML converter written in Java and based on the SableCC parser generator. This project includes utilities to convert an XML instance file into its COBOL copybook equivalent string buffer and vice versa. You can find additional information about supporting Jurasic systems here.

- Transmorpher - Transmorpher is an environment for processing generic transformations on XML documents. It aims at complementing XSLT in order to:
- describe easily simple transformations (removing elements, replacing tag and attribute names, concatenating documents...);
- allowing regular expression transformations on the content;
- composing transformations by linking their (multiple) output to input;
- iterating transformations, sometimes until saturation (closure operation);
- integrating external transformations.
- XPipe - XPipe is an approach to manageable, scaleable, robust XML processing based on the assembly line principle, common in many areas of manufacturing.

The intention of Flume is that each of the workers would provide access to a different type of technology. For example, a pipeline could consist of a Jython script worker followed by a BeanShell script worker followed by an XSLT worker.
- Smallx - Smallx supports streaming of XML infosets to allow processing of very large documents (500MB-1GB). Processing is specified in an XML syntax that describes an XML pipeline--which is a sequence of components that consume and produce infosets. This allows chaining of XML component standards like XSLT. Also, there is a full component API that allows developers to easily write their own components.

Trend Prediction in Network Monitoring Systems[收藏]
Trend Prediction in Network Monitoring Systems
March 4th, 2009 by Tim BassFollowing up on Real-Time Predictive Analytics for Web Servers I thought we should “move up a level” and look at various open network monitoring platforms with trend prediction capabilities.
Our web server management team picked Zabbix to monitor a busy production server and then we started to look into adding predictive analytics afterwards. Alberto recommended we look into The R Project for open source predictive analytics, which was interesting because I was just about to blog on TIBCO’s integration of S-Plus with Spotfire. Then, my research led me to an interesting comparative analysis regarding S, S-Plus and R based on Aberto’s recommendation. (Thanks Alberto!)
Instead of writing on S, S-Plus and R today, I thought it might be good to take a look at potential trend prediction capabilities in network monitoring systems, especially the “open, free ones” under the GPL or similar license. Based on this Wikipedia chart, A short comparison between the most common network monitoring systems, there are 3 out of 40 listed NMS platforms with trend prediction capabilities, GroundWork Community, Osmius and Zenoss. Unfortunately for us, Zabbix does not yet have trend prediction capabilities; however, the Zabbix project leader says he plans to add this functionality “in the future,” which is not very encouraging, since we don’t know what “this future functionality” will be.
Osmius claims to be event-oriented software with a “realistic and practical platform” to apply research and investigative results including AI and event correlation processes. Osmius aims reduce the volume of “final events” to process to identify the root cause of problems, including predicting problems before they occur. Osmius boasts off-line data mining capability with a pattern language to discover event occurrence patterns. We need to look into Osmius more and see if there is any substance to the marketing claims.
Unfortunately, we could not find any concrete trend prediction capabilities in GroundWork, especially in the free and open community version of the software. This makes sense since GroundWork is based on Nagios, and Nagios does not have built-in forecasting and predictive analytics. Also, a preliminary look into Zenoss was not very encouraging, as we could not find solid evidence of predictive analytics and forecasting functionality.
As for next steps, I think we’ll look a bit deeper into a few of these software platforms and see if we can find out exactly what forecasting methods they use, if any, for outage prediction. If anyone has any knowledge or experience in these NSM event processing platforms and their capabilities regarding predictive analytics and outage forecasting, please comment. Thanks!
Also, I still have some blogging to do on TIBCO’s integration of Spotfire and Insightful’s S-Plus, both acquired by TIBCO last year, as I recall. I am interested to see when and how TIBCO integrates off-line analytics (Spotfire, Insightful, S-Plus) with real-time event processing.

目前90%的病毒不再自我复制
Kaspersky Lab的高级反病毒研究员Roel Schouwenberg近日在谈到过去5年malware的变化时表示：
1、目前90%的病毒不再自我复制。
1、目前90%的病毒不再自我复制。
Criminals generally don't want to draw any attention from anti-malware companies and/or law enforcement. What also adds to this is that today about 90% of the malware we see is not self-replicating.2、malware数量迅速增长，2007年是前20年之和，2008年是2007年的10倍，目前每天发现的新威胁达4万种。
In 2008 we saw ten times as much malware as in 2007. In 2007 we saw the same amount of malware as in the whole twenty years before that combined. Right now we see up to 40,000 new threats per day, even two years ago that would have been very hard to imagine.3.写malware者向盈利性目的转变
There has also been a shift in how people are writing malware. In 2004 we were already seeing the change from people writing malware for fun to writing malware for profit. These days over 98% of all the malware we see is created with profit in mind. So we're fighting professional cyber criminals rather than teenage kids trying to prove themselves like five years ago.http://www.net-security.org/article.php?id=1219&p=1

Debian/Ubuntu Linux Install ntop[转]
Q. How do I track my network usage (network usage monitoring) and protocol wise distribution of traffic under Debian Linux? How do I get a complete picture of network activity?
A. ntop is the best tool to see network usage in a way similar to what top command does for processes i.e. it is network traffic monitoring software. You can see network status, protocol wise distribution of traffic for UDP, TCP, DNS, HTTP and other protocols.
ntop is a hybrid layer 2 / layer 3 network monitor, that is by default it uses the layer 2 Media Access Control (MAC) addresses AND the layer 3 tcp/ip addresses. ntop is capable of associating the two, so that ip and non-ip traffic (e.g. arp, rarp) are combined for a complete picture of network activity.
ntop is a network probe that showsIn interactive mode, it displays the network status on the user's terminal. In Web mode, it acts as a Web server, creating a HTML dump of the network status. It sports a NetFlow/sFlow emitter/collector, a HTTP-based client interface for creating ntop-centric monitoring applications, and RRD for persistently storing traffic statistics.Network Load Statistics
How do I install ntop under Debian / Ubuntu Linux?
Type the following commands, enter:$ sudo apt-get update
$ sudo apt-get install ntop
Set ntop admin user password
Type the following command to set password, enter:# /usr/sbin/ntop -A
OR$ sudo /usr/sbin/ntop -A
Restart ntop service
Type the following command, enter:# /etc/init.d/ntop restart
Verify ntop is working, enter:# netstat -tulpn | grep :3000
ntop by default use 3000 port to display network usage via webbrowser.
How do I view network usage stats?
Type the url:http://localhost:3000/
ORhttp://server-ip:3000/
Further readings:
- man ntop
- ntop configuration files located at /etc/ntop/ directory
- ntop project

Ubuntu8.10安装中文输入法
安装中文输入法
apt-get install scim-chinese
在/etc/X11/Xsession.d/里新建一个名叫95xinput的文件，文件内容如下
/usr/bin/scim -d
XMODIFIERS="@im=SCIM"
export XMODIFIERS
export GTK_IM_MODULE=scim
保存文件，确认内容无误后，退出X（建议退出X后运行exit命令重新login一次），再进入X的时候就可以用Ctrl+Space调出SCIM了！
现在还不能在基于GTK的软件中调出SCIM，例如不能在leafpad里使用SCIM。解决办法很简单，只要安装scim-gtk2-immodule就可以了。
apt-get install scim-gtk2-immodule
这个命令会根据依赖关系自动安装 scim-server-socket, scim-frontend-socket, scim-config-socket，如果没有安装scim，也会自动安装。

Ubuntu8.10中Eclipse SVN插件的unable to load default svn client问题
在Ubuntu8.10 Desktop，Eclipse 3.4，JDK1.6 的环境下，在Eclipse中按照下列地址安装的SVN：
http://subclipse.tigris.org/update_1.4.x
会报错“unable to load default svn client”，
解决办法：
将下面两行添加到 /usr/lib/eclipse/eclipse.ini 文件的 "-vmargs"下面
-Djava.library.path=/usr/share/java/
-Djava.library.path=/usr/lib/jni/
另外最关键的是在安装时必须选择安装SVNKit，不装这个就会报错。

vista中不能创建的目录
偶然发现在vista操作系统中,不能创建名为aux的目录。将此事作为bug向微软社区一提，
答复如下:
这个并不是BUG，而是VISTA中新的命名规则也就是说该名字无法作为文件夹名，这类的词语还包括con, aux, com1, com2, com3, com4, lpt1, lpt2, lpt3, prn 和 nul都是,主要是为了防止系统识别混淆。XP和SERVER中也是一样。
我认为像con,aux这种名字用做文件夹名是很平常的事,Vista为什么要有如此不合情理的规则? 看来，至少在设计的合理性方面，windows和linux相比不止逊色一点点。不禁让人反思，为什么那么多人好端端的linux不用，而要花那么多钱买正版的vista，图个啥？
有人提出可以用如下方式创建和删除：
mkdir c:\aux\\
rmdir c:\aux\\
的确是可以创建和删除aux文件夹，但是这个文件夹创建后无法在里面创建文件，所以只是一种治标不治本的办法。
