Re: [ns] how can implement DDoS attack using ns2

2007-11-25 Thread Arturo Servin


It would depend of what you want to do. I am using UDP and CBR in a
manual topology that I generated. There are some tools to automatic
generate a big number of nodes but I have not tested yet. Now my attacks
are confined to a small network.

 The Network Simulator ns-2: Frequently Asked Questions

(This FAQ is also on the web at
http://www.isi.edu/nsnam/ns/ns-faq.html.)

  * _Where do I get ns?_

From the ns web site at http://www.isi.edu/nsnam/ns/ns.html and
the download page http://www.isi.edu/nsnam/ns/ns-tests.html.

  * _What platforms does ns run on and what kind of hardware do I
need?_

Please see where to start on the building ns web page:
http://www.isi.edu/nsnam/ns/ns-build.html#start.

  * _What should I do if I have trouble downloading/extracting ns?_

This question is answered in detail at
http://www.isi.edu/nsnam/ns/ns-problems.html#downloading.

  * _What should I do if I encounter problems building ns?_

Check:
  1. the README that comes in the distribution (very brief),
  2. the installation problems, bug fixes and help web page
 http://www.isi.edu/nsnam/ns/ns-problems.html,
  3. the archives of the ns-users mailing list
 http://www.isi.edu/nsnam/ns/ns-lists.html,
  4. post a bug report (see below)
 http://www.isi.edu/cgi-bin/nsnam/reportbug.cgi.

  * _What do I do after I successfully build ns?_

   + Put the path to your ns executable into your PATH environment
   + Put the path to your otcl into your LD_LIBRARY_PATH
 environment
   + Put the path to your tcl library into your TCL_LIBRARY
 environment

  * _Where can I find documentation for ns?_

All documentation is linked from the main ns web page
http://www.isi.edu/nsnam/ns/. Documentation includes a tutorial
(originally from Marc Greis) and a reference manual (ns notes and
documentation).

  * _Words, words, words... that documentation is nice, but where are
some sample scripts I can start from?_

Many sample scripts can be found in the ns distribution in
~ns-2/tcl/ex and ~ns-2/tcl/test.

  * _What protocols does ns support?_

A lot! Almost all variants of TCP, several forms of multicast,
wired networking, several ad hoc routing protocols and propagation
models (but not cellular phones), data diffusion, satellite, and
other stuff. See the documentation (described above) for details,
or download ns and look.

  * _How do I know that ns correctly implements these protocols?_

Ns has validation tests that cover many protocols, see
http://www.isi.edu/nsnam/ns/ns-tests.html. However, ultimately
users are responsible for verifying that ns is accurate for their
purposes---since we cannot foresee all the ways ns may be used, we
cannot test all cases with all inputs.

  * _Are there any contributed/additional protocols not in the main
distribution?_

Yes, please see the contributed code web page
http://www.isi.edu/nsnam/ns/ns-contributed.html. The mailing list
archives can also be helpful (see below).

  * _How should I get started doing something (like implementing a new
protocol or trying an experiment)?_

We recommend that you look through the tutorial (see

 Dear all
 
 I am a newbie in NS2. I need an urgent help regarding;
 
 1- I found many main() in C++ code, although I was expecting only one,
 which
 would control the whole NS - what does this mean?
 2- Apparently 802.11e is not part of NS 2.31, and there is code available
 at
 some sites. How should I fit that separate code into the big NS 2.31;
 place
 of keeping it; recompiling steps etc?
 3- Any help specifically to change the parameter set of EDCA, during start
 of superframes? How to do it, and any code available?
 4- Do I need to understand the class hierarchy of NS 2.31 in order to run
 it
 after modifying or adding some code of my own? where to put that added
 code?
 steps involved?
 
 I would highly appreciate any help (even related to 802.11 context).
 Thank you very much.
 
 kind regards
 B
 
 

hello Basim,

plz provide information about the patch and web link so some can help. on
the other hand you should have the instructions along with the patch file to
use it with NS.

regards,

This is just an example awk script to calculate Throughput. It may help you. 

BEGIN {
ue1_throughput=0; 
}
  
{
   
  if($1==r  $4==2  $5==tcp  $8 == 0) 
{
ue1_throughput = ue1_throughput + $6 - 40;
}  
}
END {

  print Throughputs for each user equipment -
print Total throughput achieved by UE1:
(ue1_throughput/10)*(8/1000) kbps;
print End of Results; 
}
