NS2 with ubuntu

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：

到或等地方下载ns-allinone-2.33.tar.gz
因为ubuntu的source没有ns2；
# wget -c url;

(这一步可以不要,因为ns2 all in one包里就有,很多人介绍安装)
# 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......
