自己实践了一下在linux下安装ns2，很顺利；
默认安装好的xubuntu 8.04下：
到http://jaist.dl.sourceforge.net/sourceforge/nsnam/或http://sourceforge.net/project/s ... 3&package_id=169689等地方下载ns-allinone-2.33.tar.gz
因为ubuntu的source没有ns2；
# wget -c url;
下载过程中可以安装相关的库等：
# sudo apt-get install build-essential
# sudo apt-get install tcl8.4 tcl8.4-dev tk8.4 tk8.4-dev
# sduo apt-get install libxmu-dev libxmu-headers
可以把解压缩后的源码放到欲安装的位置。例如：
# sudo mkdir /usr/local/NS2
# tar xvfz ns-allinone-2.33.tar.gz
# sudo mv ns-allinone-2.33/* /usr/local/NS2
# cd NS2
# sudo ./install
安装完后，注意提示：
IMPORTANT NOTICES:
(1) You MUST put /usr/local/NS2/otcl-1.13, /usr/local/NS2/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 /usr/local/NS2/tcl8.4.18/library into your 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
可以在shell下添加更新环境变量，或者在～/.bashrc尾部添加：
export PATH=$PATH:/usr/local/NS2/bin:/usr/local/NS2/tcl8.4.184/unix:/usr/local/NS2/tk8.4.18/unix
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/NS2/otcl-1.13:/usr/local/NS2/lib
export TCL_LIBRARY=$TCL_LIBRARY:/usr/local/NS2/tcl8.4.18/library
对于是.cshrc，方式为：
set path = (/sbin /bin /usr/sbin /usr/bin /usr/local/sbin /usr/local/bin /usr/X11R6/bin
$HOME/bin /usr/local/NS2/bin /usr/local/NS2/tcl8.4.18/unix /usr/local/NS2/tk8.4.18/unix)
setenv LD_LIBRARY_PATH /usr/local/NS2/otcl-1.13:/usr/local/NS2/lib
setenv TCL_LIBRARY /usr/local/NS2/tcl8.4.18/library
做验证安装情况：
# cd /usr/local/NS2/ns-2.31
# ./validate
验证OK;
#ns
%
......ok...... |
