The old "year 1999 text" about "adding *PATH´s to .bashrc"
was meant for a "University Computer" where you had no
write permissions to /usr/.

When it's your computer, you can do :
$ cd ns-allinone-2.35/ns-2.35/ && sudo make install
('make install' will copy the executable 'ns' to /usr/local/bin/.)
Or you can do $ sudo cp ns-protocol-name /usr/local/bin/.
* Which you will have to do when using multiple ns2 versions →
You can only have one executable by name 'ns'.

The executable 'ns-<any-name>' is hard coded to know the location
of it´s libraries : ns-allinone-2.34/{ lib/*, bin/* }
I.e. adding a *PATH text to .bashrc makes no sense at all.

Xgraph : $ sudo apt-get install xgraph
Nam : If nam works →
$ cd ns-allinone-2.35/nam-*/ && sudo make install
.. Or use a valid nam package, post #2 here :

About the ns2 instructions you can find on the Internet :
The most are written by young students using Linux and ns2 for the first time.
Mostly just a copy of the texts written by other young students.
And : Don't believe everything you can read on the Internet.

So now what should I do? Should I remove the path ?

← #33 .

It's your choice. As long as you avoid using $ ns
or $ nam , an ns2 *PATH text in .bashrc makes no harm.

Read post #22 ...
/usr/local/bin/{ns, ns-orig, ns-mannasim, ns235-mannasim},
etc. etc.

But why I can run any scenario on wired node.thay are not any problem
