DisplayFusion 3.2 has been released! This is a hefty update, filled with tons of new features and a handful of bug fixes. Version 3.2 was built using community feedback (from the forums and email), and was tested extensively by the community for over 2 months. The result is one of the most stable and feature-packed releases yet! Here is just a taste of the new features in this release:

• Taskbars can now show a clock
• Multi-Monitor Screen Savers are now supported
• Added more Window Snapping options (snap mode, snap key modifier… etc)
• Window application edges are now lined up (if close enough) when snapping
• Wallpaper Profiles are now supported
• Flickr random image loader will now select from the newest 500 images, not the newest 100
• Added an Advanced Setting called “Wallpaper: Run Program After Wallpaper Change” to run an external program after each wallpaper change (like BGInfo)
• Added a “Move window to specified location” HotKey (custom) and TitleBar Button
• Added a “Toggle Window Transparency” HotKey and TitleBar Button
• Added a “Backup Settings” button to the Troubleshooting tab in the Settings window for generating a .REG file backup
• Added the ability for system Administrators to set certain settings, look in the FAQ
• Fixed some font scaling issues at lower scales (110%)
• Fixed some localization issues in the Settings window

To see the complete list of changes, please visit the DisplayFusion Change Log. As always, I would encourage everyone to update to this new version today. If you run into any issues, please visit the DisplayFusion Support page to see all of the different support options available. Thanks everyone!

我们单位用1台T3500+4个创维电视构成的一个电视墙，目前用的管理软件就是DisplayFusion 3.2，非常方便，都是快捷键实现。有多显示器的也装个试试吧，VERY GOOD！

网上有一些文档介绍如何在nginx下安装nagios，但一般都是用的nginx维基上的fcgi插件例子，我认为效果不理想，再者既然我们已经使用了fcgiwrap（Nginx下配置FastCGI.pdf），就按这个思路下去吧，所以有了这篇nginx下安装nagios。

这篇文章所述的内容我都是测试过的，有什么请大家还是到首页意见和建议联系我。

为了让大家更快速安全的安装cacti，已经在soft区里新加了一个cacti目录，专门放置cacti安装所需文件，如果有任何遗漏请大家联系我补充，谢谢！！

我们单位一直使用nagios监控服务器状态，目前官网放出了3.2.2版本，我们看看3.2.2版本有哪些特性吧

摘录：

Php5.2.14 安装后的加速和安全
注意事项：
本文档版权属于techlife.com.cn网站，以及所有人Mr.Xu，如果转载，请移步
https://techlife.com.cn/yijian.php发送申请，并请保留此版权信息。

 下文所述适用于RHEL、CENTOS、FREEBSD环境，其他未做测试。

一、加速
eAccelerator已经是很常用的PHP平台预编译加速的手段了，加速方面我们就采用这个软件
获得源代码：
https://bart.eaccelerator.net/source/

编译：需要有autoconf支持，解包后在源程序目录下：

 /usr/local/php/bin/phpize

 ./configure –enable-eaccelerator=shared –with-php-config=/usr/local/php/bin/php-config

 make;make install

Security Enhancements and Fixes in PHP 5.2.14:

• Rewrote var_export() to use smart_str rather than output buffering, prevents data disclosure if a fatal error occurs.
• Fixed a possible interruption array leak in strrchr().(CVE-2010-2484)
• Fixed a possible interruption array leak in strchr(), strstr(), substr(), chunk_split(), strtok(), addcslashes(), str_repeat(), trim().
• Fixed a possible memory corruption in substr_replace().
• Fixed SplObjectStorage unserialization problems (CVE-2010-2225).
• Fixed a possible stack exaustion inside fnmatch().
• Fixed a NULL pointer dereference when processing invalid XML-RPC requests (Fixes CVE-2010-0397, bug #51288).
• Fixed handling of session variable serialization on certain prefix characters.
• Fixed a possible arbitrary memory access inside sqlite extension. Reported by Mateusz Kocielski.

Key enhancements in PHP 5.2.14 include:

• Upgraded bundled PCRE to version 8.02.
• Updated timezone database to version 2010.5.
• Fixed bug #52238 (Crash when an Exception occured in iterator_to_array).
• Fixed bug #52237 (Crash when passing the reference of the property of a non-object).
• Fixed bug #52041 (Memory leak when writing on uninitialized variable returned from function).
• Fixed bug #51822 (Segfault with strange __destruct() for static class variables).
• Fixed bug #51552 (debug_backtrace() causes segmentation fault and/or memory issues).
• Fixed bug #49267 (Linking fails for iconv on MacOS: “Undefined symbols: _libiconv”).

To prepare for upgrading to PHP 5.3, now that PHP 5.2’s support ended, a migration guide available on https://php.net/migration53, details the changes between PHP 5.2 and PHP 5.3.

Changes with nginx 0.8.50                                        02 Sep 2010

    *) Feature: the "secure_link", "secure_link_md5", and
       "secure_link_expires" directives of the ngx_http_secure_link_module.

    *) Feature: the -q switch.
       Thanks to Gena Makhomed.

    *) Bugfix: worker processes may got caught in an endless loop during
       reconfiguration, if a caching was used; the bug had appeared in
       0.8.48.

    *) Bugfix: in the "gzip_disable" directive.
       Thanks to Derrick Petzold.

    *) Bugfix: nginx/Windows could not send stop, quit, reopen, and reload
       signals to a process run in other session.

目前官方的页面上还是RC1，国内都是RC1，俺偶然得到未放出的RC2版本，这说明flashfxp的正式版本马上就要出了，着急的朋友去软件区先睹为快吧。安装前请先读INFO.txt,本软件有patch。

辛辛苦苦写了一堆shell，由于某些不可见人的原因，我要把它们加密，就找到了shc这个工具
1) 工具说明
shell脚本是可读写的, 很有可能会泄露敏感信息, 如用户名/密码/路径/IP等. 同样在shell脚本运行时会也泄露敏感信息. shc是一个加密shell脚本的工具, 它的作用是把shell脚本转换为一个可执行的二进制文件. 这就很好的解决了上述问题.

下载安装
下载: https://www.datsi.fi.upm.es/~frosal/sources/shc-3.8.7.tgz

安装:

 mkdir /usr/local/man/man1/ (install时会把man文件放入该目录,如果该目录不存在需提前建好)

 tar vxf shc-3.8.7.tgz && cd shc-3.8.7

 make test

 make strings

 make install

     Installing shc and shc.1 on /usr/local
     Do you want to continue? <输入y>
install -c -s shc /usr/local/bin/
install -c -m 644 shc.1 /usr/local/man/man1/

用法:

 which shc

/usr/local/bin/shc

 shc

shc parse(-f): No source file specified
shc Usage: shc [-e date] [-m addr] [-i iopt] [-x cmnd] [-l lopt] [-rvDTCAh] -f script

3) 加密脚本

 shc -v -f test.sh

-v是verbose模式, 输出更详细编译日志;
-f 指定脚本的名称.
$ ll test*
-rwxr-xr-x  1 oracle oinstall   1178 Aug 18 10:00 test.sh
-rwx–x–x  1 oracle oinstall   8984 Aug 18 18:01 test.sh.x
-rw-r–r–  1 oracle oinstall  14820 Aug 18 18:01 test.sh.x.c
$ file test.sh.x
test.sh.x: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped

可以看到生成了动态链接可执行二进制文件test.sh.x和C源文件testup.sh.x.c, 注意生成的二进制文件因为是动态链接形式, 所以在其它平台上不能运行. 

4) 生成静态链接的二进制可执行文件
可以通过下面的方法生成一个静态链接的二进制可执行文件:
$ CFLAGS=-static shc -r -f test.sh
$ file testup.sh.x 

5) 通过sch加密后的脚本文件很安全吗?
一般来说是安全的, 不过可以使用gdb和其它的调试工具获得最初的源代码. 如果需要更加安全的方法, 可以考虑使用wzshSDK. 另外shc还可以设置脚本的运行期限和自定义返回信息:
$ shc -e 03/31/2007 -m "the mysql backup scrīpt is now out of date." -f test.sh
-e表示脚本将在2007年3月31日前失效, 并根据-m定义的信息返回给终端用户.

在Rob Flickenger写的linux server hacks里有过介绍，主要功能是可以把本地服务器流量传递给远程服务器，此工具可以运用在linux上以及win上。
rinetd默认的配置文件是/etc/rinetd.conf，格式很简单
源IP 源端口 目标IP 目标端口 比如
0.0.0.0 1234 1.1.1.1 22
在windows上，我们可以使用rinetd唯一的有用参数-c 来指定rinetd.conf的地址，一般来说应把rinetd.conf放在和rinetd.exe同一目录中，这样就可以用如下命令调用了
rinetd -c rinetd.conf
执行完后，DOS窗口不会退出就是成功了，你可以看看本地机器的1234启动了没有，如果启动了用putty连接看看是否可以连到1.1.1.1上？特别注意一下，用putty连接的时候IP要写127.0.0.1，否则会报错。
