Fedora 13下NS2.34安装指南
最近在做网络协议研究，需要用到网络仿真器NS2，于是在Linux系统（Fedora 13）上安装之，相对Windows系统安装比较简单，但是过程中可能会遇到些小麻烦，先总结如下：
（一）下载NS的安装包，因为是菜鸟，入门选手，也许门还没入！所以我们那个实验书上推荐一次安装全部套件，一套安装下来好像要占用个200～300M的磁盘空间。到这个网站下载最新NS-allinone套件，我现在的最新套件是 ns-allinone-2.33 , 压缩包下载下来也有50M左右。
（二）配置系统环境。其实也不算配置，只是安装几个依赖包，没有这几个依赖包，我保证你100％不能把NS安装好。要安装依赖保，只需执行下面的命令。
＃yum install gcc-c++
＃yum install libX11-devel
＃yum install xorg-x11-proto-devel
＃yum install libXt-devel
上面是主程序的编译环境和依赖包，下面这条命令是nam的依赖包，当然如果你用数据就可以分析一个模拟网络，你可以NB的不安装！
＃yum install libXmu-devel
（三）正式安装NS套件。思路： 随便进一个你的家目录下，解压套件的压缩包，软后执行安装命令，最后配置相应的环境变量。（假定我是安装在/home/mozhu/Public目录下的）
进入Public目录：
＃cd /home/mozhu/Public
解压缩安装包：
＃tar xvzf ns-allinone-2.33.tar.gz
进入解压缩后的文件夹：
＃cd/home/mozhu/Public/ns-allinone-2.33
执行里面的一个安装文件，系统就自动安装所有的东西了：
＃./install
安装完之后（得花个大几分钟的编译时间吧），会出现一些信息。如下：
Ns-allinone package has been installed successfully.
Here are the installation places:
tcl8.4.18: /home/mozhu/Public/ns-allinone-2.33/{bin,include,lib}
tk8.4.18: /home/mozhu/Public/ns-allinone-2.33/{bin,include,lib}
otcl: /home/mozhu/Public/ns-allinone-2.33/otcl-1.13
tclcl: /home/mozhu/Public/ns-allinone-2.33/tclcl-1.19
ns: /home/mozhu/Public/ns-allinone-2.33/ns-2.33/ns
nam: /home/mozhu/Public/ns-allinone-2.33/nam-1.13/nam
xgraph: /home/mozhu/Public/ns-allinone-2.33/xgraph-12.1
gt-itm: /home/mozhu/Public/ns-allinone-2.33/itm, edriver, sgb2alt, sgb2ns,sgb2comns, sgb2hierns
Please put /home/mozhu/Public/ns-allinone-2.33/bin:/home/mozhu/Public/ns-allinone-2.33/tcl8.4.18/unix:/home/mozhu/Public/ns-allinone-2.33/tk8.4.18/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.
IMPORTANT NOTICES:
(1)You must put /home/mozhu/Public/ns-allinone-2.33/otcl-1.13,/home/mozhu/Public/ns-allinone-2.33/lib,
into your LD_LIBRARY_PATH environment variable.
If it complains about X libraries, add path to your X libraries
into LD_LIBRARY_PATH.
If you are using csh, you can set it like:
setenv LD_LIBRARY_PATH
If you are using sh, you can set it like:
export LD_LIBRARY_PATH=
(2) You MUST put /home/mozhu/Public/ns-allinone-2.33/tcl8.4.18/library intoyour TCL_LIBRARY environmental
variable. Otherwise ns/nam will complain during startup.
After these steps, you can now run the ns validation suite with
cd ns-2.33; ./validate
