注意：在普通用户在Fedora 8下安装ns2.30,最好不要在root下，虽然也可以安装成功，如果提示权限问题，请确认是安如下步骤进行，否则有可能你的解压在非此用户进行的。
1.http://www.isi.edu/nsnam/ns/ns-build.html下载最新版本，我这是ns2.30,ns-allinone-2.30.tar.gz
2.cp到你的目录~/
3.解压:tar -zxvf ns-allinone-2.30.tar.gz
4.安装：cp /ns-allinone-2.30
./install
等上5分钟左右，出现以下信息
Nam has been installed successfully.
Ns-allinone package has been installed successfully.
Here are the installation places:

otcl: /home/ninga/ns-allinone-2.30/otcl-1.12
tclcl: /home/ninga/ns-allinone-2.30/tclcl-1.18
ns: /home/ninga/ns-allinone-2.30/ns-2.30/ns
nam: /home/ninga/ns-allinone-2.30/nam-1.12/nam

gt-itm: /home/ninga/ns-allinone-2.30/itm, edriver, sgb2alt, sgb2ns, sgb2comns, sgb2hierns
Please put /home/ninga/ns-allinone-2.30/bin:/home/ninga/ns-allinone-2.30/tcl8.4.13/unix:/home/ninga/ns-allinone-2.30/tk8.4.13/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.
IMPORTANT NOTICES:
(1) You MUST put /home/ninga/ns-allinone-2.30/otcl-1.12, /home/ninga/ns-allinone-2.30/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/ninga/ns-allinone-2.30/tcl8.4.13/library into your TCL_LIBRARY environmental
variable. Otherwise ns/nam will complain during startup.
(3) [OPTIONAL] To save disk space, you can now delete directories tcl8.4.13
and tk8.4.13. They are now installed under /home/ninga/ns-allinone-2.30/{bin,include,lib}
