.. it does not display : Please install a valid nam package :

$ sudo apt-get remove nam
... and remove any nam you may have on your OS,
i.e. 'nam' executable´s and nam-1.**/ folders.

Nam packages that will work, post #2 here ...
http://www.linuxquestions.org/questi...-4175524760/#2

Note : A file.tcl must be attached as file.tcl.txt,
and a unique file name must be used, like sm3-mary1001.tcl.txt

About your file : No issues here, the nam window opens OK.

yes yes my nam has an error, when i run nam command in terminal it has this error : Segmentation fault
what should i do?

← #3 .

Segmentation fault :
That's the error from all the faulty Ubuntu nam packages.
It's old news :
No valid nam packages for any later Ubuntu versions for many months.

Solution :
Install a proper package for your OS → Read post #2.

Any doubts : Specify your OS →
a) Please show the output from the command $ uname -m
b) $ cat /etc/issue

HP-PC ex # uname -m

← #5 . OK, Mint 17.1 - 64bits.

Released a few days ago. Mint 17.1 = Ubuntu 14.04.

You can use the package nam_1.15-10-ubuntu14_amd64.deb :
1) $ sudo apt-get remove nam
2) Download the new package, click the package,
and your 'Package Installer' will install it.

hi
can anyone send me a scenario like the one in #1 (sm.tcl) ?
wireless with more than 30 nodes and aodv routing....
i want to know if the problem is with my scenario !!!

← #8 .

The file in post #1 is not a scenario file. Is a simulation file.

AODV with > 30 nodes : Please see this example → →
http://enggedu.com/ns2_simulator/ns2...ffic/index.php
= Aodv-enggedu.tcl : Can be expanded to more than 30 nodes.

My test (-example) is with 33 nodes : Aodv-enggedu-33.tcl
