0. Install Red Hat 9 (complete installation is the best; otherwise include all ‘development tools’, ‘kernel development tools’, development programs (tk, gcc etc) ). Othewrwise, during NS installation, tck./tk etc can’t/fail to install.

(0) Download ‘ns-allinone-x.xx.tar.gz’

(1) Put the tar-ball into /usr/src and apply “tar xzvf ns-allinone-x.xx.tar.gz”

(2) Go into the newly formed “ns-allinone-x.xx” folder and type “./install”

(3) At the end follow the instruction to edit system files. To do so:

a) Type “gedit .bashrc” ( dot bashrc)

b) Type at th end of bashrc:

export PATH=$PATH:<\usr………>

Note: <……> path is derived at the end of tar-ball installation.

# .bashrc

# User specific aliases and functions

alias rm='rm -i'

alias cp='cp -i'

alias mv='mv -i'

# Source global definitions

if [ -f /etc/bashrc ]; then

. /etc/bashrc

fi

export PATH=$PATH:/usr/src/ns-allinone-2.1b7a/bin:/usr/src/ns-allinone-2.1b7a/tcl8.3.2/unix:/usr/src/ns-allinone-2.1b7a/tk8.3.2/unix

export LD_LIBRARY_PATH=/usr/src/ns-allinone-2.1b7a/otcl-1.0a6:/usr/src/ns-allinone-2.1b7a/lib

export TCL_LIBRARY=/usr/src/ns-allinone-2.1b7a/tcl8.3.2/library

---------------------------------------------------------------------------------

(4) Restart the PC and at terminal simply type “ns”. It will work.

Blog: I tried in Fedora 5 but failed.

Later I got back to old Redhat 9 and got success J
