hello! i am a newbie to linux as well as ns-2.34 , working with it for my FYP on asymmetric mobile adhoc networks. All was going well untill now i dont know what actually happened my nam is not working properly it is showing the following error
Cannot connect to existing nam instance. Starting a new one...
as well as this one
*** !!! ***
nam cannot recognize the trace file tmp
Please make sure that the file is not empty and it is a nam trace

kindly guide me what to do ???

Welcome to LQ.

Is it the ns-allinone-2.34/nam-1.14/ ? Or is it an installed Ubuntu package ?

"Cannot connect to existing nam instance. Starting a new one..." :
→ Is the normal behavior.

May be it isn't a usual "out.nam" that you are trying to open ?

Please make a nam test with a well tested out.nam :
The attached `Marc Greis´ example3.tcl will create the perfect out.nam
( Ref. http://www.isi.edu/nsnam/ns/tutorial/nsscript3.html )

perl visualize.pl Obstacles.txt 10 simple-manet.nam
it gives his error
Cannot connect to existing nam instance. Starting a new one...
*** !!! ***
nam cannot recognize the trace file tmp
Please make sure that the file is not empty and it is a nam trace

MCM, Mission Critical Mobility model :
The " www.wltl.ee.upatras.gr/mcm/‎ " links are currently down,
have you got another link for the files ?

Ubuntu : Please specify your version, and :
? What is the output from the command $ uname -m <Enter>

http://www.wltl.ee.upatras.gr/mcm/
yup used the same mcm website ...my tcl script my scenario file and trafic file it gives out a .nam file as well as .tr
but when i try to visualize it perl visualize.pl Obstacles.txt 10 simple-manet.nam
it gives the error i stated above

# 6 .

Did you check http://www.wltl.ee.upatras.gr/mcm/ ?
... The link is still down here.


Repeat : Ubuntu : Please specify your version, and :
? What is the output from the command $ uname -m <Enter>

Ubuntu version is 12.10
ns version is ns-allinone-2.35 package
yes i have used the same website for mcm simulation ....

# 8 .

Did you do a check with the link right now ?
→ http://www.wltl.ee.upatras.gr/mcm/
.... The link doesn't work here.
Alternatively you can upload the MCM files as a package, to GoogleDocs,
then I will make a test build etc. with Ubuntu 12.10 - <?>.
The two "12.10" versions are Ubuntu 12.10-i686 and Ubuntu 12.10-x86_64 →
→
→ Repeat : Please show the output from the command $ uname -m
.. to decide if your OS is i686 or x86_64.
It's actually crucial, as not all protocols will work with both 12.10 versions.

configure: error: Installation of tcl seems incomplete or can't be found automatically.
Please correct the problem by telling configure where tcl is
using the argument --with-tcl=/path/to/package
(perhaps after installing it),
or the package is not required, disable it with --with-tcl=no.

# 10 .

"./configure" won't do, when it is ns-2.35. Is for all earlier versions.
Do a $ make clean in ns-2.35, and edit the Makefile.in : `mobile/obstacle.o´
then go to the top directory ns-allinone-2.35/,
and do $ ./install

The link http://www.wltl.ee.upatras.gr/mcm/ is up again.
But I can't unzip the package mcm.zip ( 'unzip' or '7z x' ).
? How did you unpack "mcm.zip" ?
EDIT : The downloaded mcm.zip is 4.8 kB !

-

for unzipping mcm use this command

tar -xzvf mcm11.tar.gz

secondly i have to patch mcm with ns-2.35 but every time i try to run install_mcm it dosent work

./install_mcm dosent works either
sudo install_mcm dosent work
how to install it?????

# 12 .
Please supply a link to "mcm11.tar.gz".

Or upload mcm11.tar.gz to e.g. `Google Docs,
and show a link to the package.

i am sorry actually i renamed my mcm "mcm11"
follow the same command for mcm

how do i run install_mcm ???

# 14 .

Please upload a usable package "mcm.?" to Google Docs.
