i am using ubuntu 8.04. i have installed ns-2.34. i extracted it in the directory /home/bambos. i then wrote the following lines of code at the end of the bash file.

# LD_LIBRARY_PATH
OTCL_LIB=/home/bambos/ns-allinone-2.34/otcl-1.13
NS2_LIB=/home/bambos/ns-allinone-2.34/lib
X11_LIB=/usr/X11R6/lib
USR_LOCAL_LIB=/usr/local/lib
export

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$OTCL_LIB:$NS2_LIB:$X11_LIB:$USR_LOCAL_LIB

# TCL_LIBRARY
TCL_LIB=/home/bambos/ns-allinone-2.34/tcl8.4.18/library
USR_LIB=/usr/lib
export TCL_LIBRARY=$TCL_LIB:$USR_LIB

# PATH
XGRAPH=/home/bambos/ns-allinone-2.34/bin:/your/path/ns-allinone-2.34/tcl8.4.18/unix:/your/path/ns-allinone-2.34/tk8.4.18/unix
NS=/home/bambos/ns-allinone-2.34/ns-2.34/
NAM=/home/bambos/ns-allinone-2.34/nam-1.14/
PATH=$PATH:$XGRAPH:$NS:$NAM

after this i run the command

source ~/.bashrc

in the terminal and then restarted my computer. after that i tried to run a program that i wrote by giving the command

ns example.tcl

in the terminal which gave the following error message:

example.tcl does not exist, try again

i then gave the command

$ns example.tcl

in the terminal and it gave the following error message:

bash: /home/bambos/ns-allinone-2.34/ns-2.34/example.tcl: Permission denied

what can possibly be going wrong? if you need more info on my problem please let me know in case i left something out.

thank you in advance guys

Hi

Did you check the files' permissions? You didn't tell about that.

And BTW, if you 'source' your bash config file, there is no need to reboot.

hi mojo

thank you for replying. no i did not check the files permissions. how can i do that?

i also validated it and it came up with

what do i do
thanks in advance

hi again guys,

i think i managed to overcome the problem i had before. i used the command

chmod u+x filename

in the terminal and then run the following program

set ns [new Simultator]

set n0 [$ns node]
set n1 [$ns node]

$ns duplex-link $n0 $n1 1Mb 10ms DropTail

set tracefile [open out.tr w]
$ns trace-all $tracefile

set nf [open out.nam w]
$ns namtrace-all $nf

proc finish {}
{
global ns tracefile nf
$ns flush-trace
close $nf
close $tracefile
exec nam out.nam &
exit 0
}

$ns at 5.0 "finish"

$ns run

by typing $ns example.tcl in the terminal but i got the following errors.

/home/bambos/ns-allinone-2.34/ns-2.34/example.tcl: line 6: duplex-link: command not found

can someone please tell me what went wrong?

thanks a lot mates

Your modified file is attached as "mate1984example.tcl.txt
( Formatting was changed. May not work as you intended ?
But it will display in nam.)

P.S. : I don't know, why your validation fails, usually no errors
with ns-allinone-2.34 at Ubuntu 8.04 Hardy. Will test it later.

Attached Files

mate1984example.tcl.txt (685 Bytes, 2 views)

Required : libx11-dev , libxmu-dev , libxmu-headers , libxt-dev , libtool

And this may fix your issues ? :
sudo apt-get remove tcl8.3 tcl8.4 tcl8.5
.. Will prevent ns2 applications from compiling with any system tcl, tk.
(You can install tcl8.4 tk8.4 , when ns2 install and validate are finished.)

sudo apt-get install g++ libstdc++6 libstdc++6-4.2-dev libc6-dev
.. to be sure, they are updated.

'validate' result :

hi again guys,

first of all thanks for the time and effort you put in helping me.

unfortunately i still can't get it to run. dear knudfl it seems that i don't have

libx11-dev , libxmu-dev , libxmu-headers , libxt-dev , libtool.

how can i get them i case that is what is causing all my problems. also i gave the command

sudo apt-get remove tcl8.3 tcl8.4 tcl8.5

and i got the following

Reading package lists... Done
Building dependency tree
Reading state information... Done
Package tcl8.3 is not installed, so not removed
Package tcl8.4 is not installed, so not removed
Package tcl8.5 is not installed, so not removed
The following packages were automatically installed and are no longer required:
linux-headers-2.6.24-19-generic libdns35 linux-headers-2.6.24-19
Use 'apt-get autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

i then proceeded to giving the command

sudo apt-get install g++ libstdc++6 libstdc++6-4.2-dev libc6-dev

and got the following

Reading package lists... Done
Building dependency tree
Reading state information... Done
g++ is already the newest version.
libstdc++6 is already the newest version.
libstdc++6-4.2-dev is already the newest version.
libc6-dev is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

i also tried to install

tcl8.4/tk8.4

and i got

Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Release 'tk8.4' for 'tcl8.4' was not found

i still can get any program to run. is it advisable to uninstall ns2 and reinstall it again in case something went wrong there or i didn't get all the file necessary?

again thanks a lot for your time mate.

The command is of course :
sudo apt-get install tcl8.4 tk8.4
Also easier to find valid package names, by doing this first:
sudo apt-cache search tcl8.4
.. Or use the "package search site"
Example : http://packages.ubuntu.com/hardy/tcl8.4
( Or use the search in 'synaptic )
... Sorry, if I confused you with the tcl/tk "word".
But : Do not install tcl8.4 tk8.4 before building ns2.

I do not know, what your 'validation' issue is now.
Suggest : Delete all ns-allinone-2.34 and start from scratch,
and : cd ns-allinone-2.34/ && ./install
..

hi guys,

i have just reinstalled ns 2.34. the validation issue was overcome but i am still not able to run a single code with the same errors. every time i give the command

ns myfile.tcl

it keeps telling my that no such file or directory exists. on the other hand if i change the command to

$ns myfile.tcl

it gives the error permission denied.

nothing seems to be happening. any suggestions.

thanks a lot again for your time

hi mates

i don't know how to thank you everything seems to be working just fine. thanks a lots

hello

am getting problem with ./configure getting error like this
/ns-allinone-2.34/ns-2.34$ ./configure
./configure: line 1520: config.log: Permission denied
./configure: line 1530: config.log: Permission denied


i tried to enable permission its denied? how can solve this?

Post #12, @yashu.

Install ns-allinone-2.34 in /home/yashu/ (Or any folder in /home/yashu/)

Then there should be no more permission issues.


By the way : Why are you using './configure' in ns-2.34/ ? ?

.

to perform otcl linkage

1) i have to exe ./configure
2)make
3) make clear

am trying to exe these commands

hi,

i want obstacle model in ns2.33,how can i add? please help me

# 14.

Probably have a look here http://moment.cs.ucsb.edu/mobility/
> http://moment.cs.ucsb.edu/mobility/R...tacleModel-NS2

> Libraries http://moment.cs.ucsb.edu/mobility/libraries.html
> Plugins http://moment.cs.ucsb.edu/mobility/plugins.html
Don't know which ns2 it's for, but then again :
You can have as many versions of ns-allinone-2.xx as you want,
installed at the same time. But do not add any of them to a *PATH.

Other info : Google .. ns2 obstacle model ..
