otcl: /root/nn/ns-allinone-2.35/otcl-1.14
tclcl: /root/nn/ns-allinone-2.35/tclcl-1.20
ns: /root/nn/ns-allinone-2.35/ns-2.35/ns

---------------------------------------------------------------------
Please put /root/nn/ns-allinone-2.35/bin:/root/nn/ns-allinone-2.35/tcl8.5.10/unix:/root/nn/ns-allinone-2.35/tk8.5.10/unix
into your PATH environment; so that you'll be able to run itm/tclsh/wish/xgraph.
IMPORTANT NOTICES:
(1) You MUST put /root/nn/ns-allinone-2.35/otcl-1.14, /root/nn/ns-allinone-2.35/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 /root/nn/ns-allinone-2.35/tcl8.5.10/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
For trouble shooting, please first read ns problems page
http://www.isi.edu/nsnam/ns/ns-problems.html. Also search the ns mailing list archive for related posts.

Step 7:Understand this important instruction properly and set path according the instruction.

Step 8:As per instruction, we modify two file name as a .bash_profile and .bashrc which are already hide in ns-allinone-2.35 Folder, so we need to unhide of all the file in ns-allinone-2.35 Folder.

Step 9:Modify .bash_profile file as follows:
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/root/ns-allinone-2.35/bin:/root/ns-allinone-2.35/tcl8.5.10/unix:/root/ns-allinone-2.35/tk8.5.10/unix
LD_LIBRARY_PATH=/root/ns-allinone-2.35/otcl-1.14:/root/ns-allinone-2.35/lib
TCL_LIBRARY=/root/ns-allinone-2.35/tcl8.5.10/library
export PATH
unset USERNAME

Step 10:Modify .bashrc file as follows:
# .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
PATH=$PATH:$HOME/bin:/root/ns-allinone-2.35/bin
Step 11:Save that two file and close terminals and all file, folder. Reopen a terminal and write the ns command. If % sign display as responds. This means ns-2 successfully install on machine.
