Hi
i have installed ns2.35 in Mint17 but i modified an add some thing to ns2. now i have some problems that i think by reinstalling ns2 may be my problems will solve.
my OS is 64 bit.
so i want to know:
1- how uninstall ns2.35
2- i want a reliable ns2 file, where can i get it? i get here :http://sourceforge.net/projects/nsna...e=typ_redirect
3- how to install it.

The original ns-allinone-2.35 :
http://sourceforge.net/projects/nsnam/

ns-allinone-2.35 updated to gcc / g++ version 4.8.2 ... 4.9.1 :
https://drive.google.com/file/d/0B7S...ew?usp=sharing
→ ns-allinone-2.35_gcc482.tar.gz

ns-allinone-2.35 updated, also to include ns2 official Codel patches etc.:
https://drive.google.com/file/d/0B7S...ew?usp=sharing
→ ns-allinone-2.35_gcc491.tar.gz

Latest update = ns-allinone-2.36.rc1.tar.gz
http://www.isi.edu/nsnam/dist/releas....36.rc1.tar.gz


Removing a folder "ns-allinone-2.35/" : $ rm -r ns-allinone-2.35/
* But really not required :
You can have as many ns-allinone-2.35 as you want,
installed at the same time.
But do not add any *PATH text to .bashrc.


Add 3) : 3- how to install it.
? Why ask ? You have done ns-allinone-2.35 builds several times.
Old 2011 version : $ export CC=gcc-4.4 CXX=g++-4.4 && install
Updated versions : $ ./install

i am realy thankful to you for your help...

i dont know what happend for my ns now. it worked very well, but now every thing has problem also the protocol that i did not change them. i reinstall the ns2.35, but again i dont know why sometimes a simple tcl cant run...
i use aodv and i usualy see this error: "ns: scheduler going backwards in time from 72.997428 to 0.000000."

i add a aodv-malicious_ns235.patch as you say here :http://www.linuxquestions.org/questi...-a-4175505657/ #6

but by runing a tcl scenario in each time i get diffrent errors like :

PacketQueue:: remove() couldn't find target
or
ns: scheduler going backwards in time from 180.507428 to 0.000000.
or
Segmentation fault


i attach the tcl file,by puting different hacker nodes in this scenario in each time that i run the scenario, i get different errors...
i dont know why?!!! my ns2.35 is the source that i install today.

Make sure that you are using a named copy of 'ns' for any added protocol.
Like 'ns235-malicious' : That's for hacker / malicious simulations.

And another 'ns' for default simulations (ns-orig, ns235, ns235-orig).
Not all the default files.tcl may work with "ns235-malicious".

Also :

Are you sure that your Mint 17 is the 32bits (i686) version ?

no i tellyou in #1 that my OS is 64bit...mint 17.1 64bit

so you say "PacketQueue:: remove() couldn't find target" is not a error? and is the scenario compeletly run?

sorry if you can plz put more than 3 or 4 nodes hacker to my scenario you can see another errors as i told in #3

why this happend? i run this before and i never had this errors.

← #6 .

Sorry. I missed the "64 bit".

Your errors : May be you updated some packages ?
* Updates will constantly change the OS.
And by using a 64bits OS for ns2 :
You are always close to the point of "not working at all".

Generally : ns2 is for a 32bits OS.
However, some protocols may work OK with a 64bits OS.
( You will always get a poor validate result.)

realy?!!! ohhhh my God.
so i should change to 32bit

i think you are right...it can be the main reason of this problem...
thanks a lotttttt...

is it nessesery that i use a named copy of 'ns' for any added protocol?!! i think by adding a malicious node to aodv if any malicious node be in the tcl file ,bu run "...$ns name.tcl" could be run..it is not deffirent with using a "...$ns235-malicous name.tcl" is it?

my problem does not solved by changing my OS from 64bit to 32bit....i have all the problem in #3 . for example by runing this scenario i see segmentation fault error....but the trace file created (the scenario that i attached here).

plz tell me whats the problem with me?

error:

me@me-HP-ENVY-15-Notebook-PC ~/Desktop/exa $ ns sm.tcl

... How about using some unique file names ?
And please also use unique names for files.tr, instead of sm.tr.

Your file sm"5".tcl, attached to the above post #1 :
No `Segmentation fault´ here with : set val(nn) 20
( Can result in 'Segmentation fault' with :
less than 20, or more than 20 nodes.)
