引言
    晚唐诗人许浑曾写过一首诗《咸阳城东楼》，其中有一句名句，被传诵千古：山雨欲来风满楼。
    “山雨欲来风满楼”，是全诗的警句。周围的群山，雨意越来越浓，大雨即将到来，城楼上，已是满楼的狂风。全句只有寥寥七个字，却十分形象地写出了山城暴雨即将来临时的情景，使读者仿佛身临其境一般。因为这里作者准确地抓住了暴雨到来前狂风满楼的这种自然界变化的特点。但是，作者并不仅仅只是写自然界的变化，而是包含着另外一层意思。
    其实，不仅在自然界中有“山雨欲来风满楼”，在由比特组成的数字虚拟世界中，同样也存在“山雨欲来风满楼”的情景。这，就是网络中的广播风暴。广播风暴你也许没有听说过，但，你或多或少曾经遇到过广播风暴。
    本文将就广播风暴的定义、原因、以及应对手段等方面做一番阐述。

废话开讲前，请大家先看看我的屏幕效果图一张：

默认Ubuntu Gutsy，默认的Compiz Fusion，安装Freewins插件
先下载这个 [url]http://img1.51cto.com/attachment/200711/69882_1194308328.zip[/url]
看实录，包括错误和处理
lzy@Gusty:~$ cd freewins-0.3-0.6
lzy@Gusty:~/freewins-0.3-0.6$ ls
AUTHORS freewins.c freewins.xml Makefile
COPYING freewins.o libfreewins.la
lzy@Gusty:~/freewins-0.3-0.6$ make clean
rm -rf *.lo *.o libfreewins.* .libs *~ freewins.schema
lzy@Gusty:~/freewins-0.3-0.6$ make
libtool –mode=compile gcc `pkg-config –cflags compiz` -Wall -shared -c -o freewins.lo freewins.c
Package compiz was not found in the pkg-config search path.
Perhaps you should add the directory containing `compiz.pc’
to the PKG_CONFIG_PATH environment variable
No package ‘compiz’ found
/bin/sh: libtool: not found
make: *** [freewins.lo] 错误 127

通过新立得软件包管理器搜索libtools安装上并重新来一遍：

lzy@Gusty:~/freewins-0.3-0.6$ make
libtool –mode=compile gcc `pkg-config –cflags compiz` -Wall -shared -c -o freewins.lo freewins.c
Package compiz was not found in the pkg-config search path.
Perhaps you should add the directory containing `compiz.pc’
to the PKG_CONFIG_PATH environment variable

make: *** [freewins.lo] 错误 1

晕，请教酷狗大神后找到治疗秘方：

lzy@Gusty:~/freewins-0.3-0.6$ sudo apt-get install compiz-bcop compiz-dev build-essential libxcomposite-dev libpng12-dev libsm-dev libxrandr-dev libxdamage-dev libxinerama-dev emerald libstartup-notification0-dev libgconf2-dev librsvg2-dev libdbus-1-dev libdbus-glib-1-dev libgnome-desktop-dev x11proto-scrnsaver-dev libxss-dev libxslt1-dev libtool
……
……
装完后重来，
make clean
make
mkdir -p ~/.compiz/metadata/
make install
