Install the network simulation software of NS2.

For many of my friends, it seems that it is difficult to install the ns2-based Network Simulation Software in Ubuntu. I would like to write it out and share it with you. NS2. is a set of famous network simulation software, I think the installation on Ubuntu is still simple, the first thing to install is: # sudoapt-getinstallbuild-essential # sudoapt-getinstalltcl8.4tcl8.4-devtk8 Which of the following network simulation software is used in Ubuntu 6?

For many of my friends, it seems difficult to install the ns2-network simulation software in Ubuntu. I 'd like to write it out and share it with you.

NS2. it is a well-known network simulation software. I think it is simple to install it on Ubuntu. The first thing to install is:

# 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

First download the NS2. (http://jaist.dl.sourceforge.net/sourceforge/nsnam/ns-allinone-2.32.tar.gz) the latest version is 2.32.

Linux community suggestion: you can move the decompressed folder to the location you want to install. For example:

# Tar xvfz ns-allinone-2.31.tar.gz
# Sudo music ns-allinone-2.31/usr/local/NS2.
# Cd NS2.
#./Install

After waiting for some time, you will see a message asking you to modify. bashrc or. cshrc. Add it as prompted.

For example, my. cshrc will move or add the following lines:

Set path = (/sbin/bin/usr/sbin/usr/bin/usr/games/usr/local/sbin/usr/local/bin/usr/X11R6/bin
$ HOME/bin/usr/local/NS2./bin/usr/local/NS2./tcl8.4.14/unix/usr/local/NS2./tk8.4.14/unix)

Setenv LD_LIBRARY_PATH/usr/local/NS2./otcl-1.13:/usr/local/NS2./lib
Setenv TCL_LIBRARY/usr/local/NS2./tcl8.4.14/library

If it is. bashrc, it will be:

Export PATH = $ PATH:/usr/local/NS2./bin:/usr/local/NS2./tcl8.4.14/unix:/usr/local/ns2-tk8.4.14/unix
Export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH:/usr/local/int32/otcl-1.13:/usr/local/int32/lib
Export TCL_LIBRARY = $ TCL_LIBRARY:/usr/local/NS2./tcl8.4.14/library

Next, perform verification based on the last few lines of information, for example:

# Cd ns-2.31;./validate

After he finishes running, he can work (it's too slow to do this step ).

If "%" appears when "ns press ENTER", the statement is correct.

If there is a problem, run./install again after the above work is completed.
