Executing .sh script to run ZRP simulations on patched NS-2.35

EddieXS · 07-23-2019, 03:00 PM

Running ns-2.35 on ubuntu 16.04 doing an analysis of different routing protocols. No problems with AODV & DSDV as i know they are in the base version. Have got an automation script that runs and takes in my simulation results and creates neat folders and .csv files.

After a struggle getting ZRP patched in and successfully testing the demos from a tutorial: https://www.linuxquestions.org/quest...on-4175526171/ Post #7

I tried to change my existing .tcl file to run the ZRP simulation using my .sh automation by using:

Quote:

set val(rp) ZRP ; #Routing protocol

...

Agent/ZRP set radius_ 2; # Setting ZRP radius =2

But the result i get at this point is

Quote:

$ ns235-zrp ./automate.sh
invalid command name "mkdir"
while executing
"mkdir mobility_files"
(file "./automate.sh" line 4)

And if i try run it without using the ns235-zrp command (just to test out different options) i get:

Quote:

invalid command name "Agent/ZRP"
while executing
"Agent/ZRIP set radius_2 "

Not entirely sure what to do at this point as the older forum answers seem to have run dry.

Let me know if you need anything more information about the steps i took upto this point.

Welcome to LQ.

Also ref. https://stackoverflow.com/questions/...after-patching

You can of course not use a tcl-otcl interpreter like 'ns' to run a shell script.
It is `$ ./automate.sh´ ... or if it's a bash script also `$ bash automate.sh´

Quote:

invalid command name "Agent/ZRP"
.
"Agent/ZRIP set radius_2 "

See the EDIT below ...

Ubuntu 16.04: No issues with ns-2.35 + ZRP, unless you changed the default compiler:
The ns-2.35 2014 update (ns-allinone-2.35_gcc482.tar.gz or ns-allinone-2.35_gcc5.tar.gz) requires g++ version <= gcc-5.4 ( ver. 4.4 .. 5.4 No PIE.)

Build example

Code:

tar xvf ns-allinone-2.35_gcc5.tar.gz
https://drive.google.com/file/d/0B7S...ew?usp=sharing
cd ns-allinone-2.35/
patch -p0 < zrp-ns235.patch
https://drive.google.com/file/d/0B7S...ew?usp=sharing
./install
        // ( or : export CC=gcc-4.8 CXX=g++-4.8 && ./install )
cd ns-2.35/
cp ns ns235-zrp
sudo cp ns235-zrp /usr/local/bin/

------------ Simulation ----------
ns235-zrp zrp-Demo1-1.tcl

zrp-examples-06.2019.tar.gz

EDIT : You have some typo´s → "Agent/ZRIP set radius_2 " ... must be:

Code:

Agent/ZRP set radius_ 2

I should have attached both. I have renamed what was called aodv.tcl to zrp-setup.tcl to make it appropriate for the actual protocol I am using within it, please let me know if you think more detail should be in the file name.

EddieXS · 07-26-2019, 10:26 AM

I hope its okay for me to make another reply on here. Just been testing with my actual AODV script that worked, thought i would try open one of my simulations in nam (Which i've used successfully with it plenty before) and now im getting the following error that could be related to whats going on with the above?

Quote:

$nam
Can't find a usable init.tcl in the following directories:
:/opt/ns-allinone-2.35/tcl8.5.10/library/

This probably means that Tcl wasn't installed properly.

Aborted (Core dumped)

Like i say this definitely worked before i started trying to implement the ZRP patch.

knudfl · 07-26-2019, 01:41 PM

Re #5.

"automate.sh" : Line 43, the command is not ns but ns235-zrp.
My line 43: ns235-zrp zrp-setup.tcl mobility_files/mob$i
(The command 'ns235-zrp' can usually also be used for simulations with other protocols.)

"zrp-setup.tcl", line 50 : Must be `# source $mobility´, i.e. commented out.
→ You already have the real settings of $mobility in automate.sh

About nam :
Better install a package for your OS, e.g. nam_1.15-10-ubuntu14_amd64.deb
https://www.linuxquestions.org/quest...-4175524760/#2
... Delete the current 'nam', or hide it away.
Note : There is no usable nam package from Ubuntu for versions 14* .. 17.04.
Oct 2014: https://bugs.launchpad.net/ubuntu/+s...m/+bug/1376970
→ fixed after 42 months!

Download the package ... and install

Code:

sudo gdebi Downloads/nam_1.15-10-ubuntu14_amd64.deb

P.S.: Will appreciate a copy of your "analysis.awk".

Hi, many apologies for the late response.

I have spent the last few days starting again with my VM & Ubuntu, creating backups along each step of the way to make this process much easier.

Now that is sorted I have started at the point of installing everything fresh using the steps and files provided in post #2

Moving the file, using tar and applying the patch seems to work fine (files appear to transfer), but once ./install is used the following error occurs:

Code:

I was unsure how much of the error was relevant so i tried to go up as far as i could.

This means ns has not installed correctly at all? I am not sure if i have missed anything else to do before the patch & ./install

Aside from the steps given here before i began i went through the standard steps i have gone through previous to get my unpatched version of ns-2.35 working:

Code:

sudo apt-get update
sudo apt-get install gcc
sudo apt-get install build-essential autoconf automake
sudo apt-get install tcl8.5-dev tk8.5-dev
sudo apt-get install perl xgraph libxt-dev libx11-dev libxmu-dev

Again im very sorry for the late response, and i hope the steps i have taken to start fresh and get this working are reasonable.
I have also still attached analysis.awk for you to take a look if you wish to do so.

EddieXS · 07-28-2019, 06:39 AM

Ah! forget my last post i believe.

I left it for a few minutes, checked my permissions (sudo chmod -R 777 FILENAME) everywhere i had been using, and retried ./install

Worked!
Tested the demo, no problem

Altered my files as you suggested (No changes to .awk) and the simulation has run sucessfully.

Currently nam is still playing up but i will follow your instructions to sort that (i also have a working version on my other VM copy so i can transfer files over to that one if needs be)

I was wondering if it would be okay for me to do one last final post on here, explaining every step i went through to get towards this stage? As i know i struggled so much i would like to leave a full tutorial with any fiddly bits in it people may not know they need to do

Re #8, #9.

Thank you for the awk script.

gcc-4.8 : $ apt-get install g++-4.8
Suggest a search when packages are wanted: $ apt-cache search gcc-4.8
Or on-line https://packages.ubuntu.com/search?s...searchon=names
Or install `synaptic´ package manager. Can search in all the 40,000 available packages.

About gt-itm/ :
ns-allinone-2.35_gcc5.tar.gz has an ns-allinone-2.36 version. Worked for a short time.
The current most usable gt-itm/ is found in ns-allinone-2.33 .

Not a good idea to use opt/ for package builds.
Default / safe is /home/name/tmp/ ... and for ns2: /home/name/ns2/(protocol)
I.e. you are exposed for attacks whenever using sudo.

Sorry I just need some clarity on this, when i install NS2 it is safer / better to place into directory /home/name/ns2 ?

Thankyou again for all your help.
