Welcome to the ns-users mailing list!
We automatically send this message to every new person who sends mail
to the list. You should only receive it once. My apologies if the
program contacts you twice, perhaps because you have multiple e-mail
addresses or send mail from multiple machines.
If you are an experienced ns-user who simply has not posted since we
started using this responder, our apologies for inconveniencing you
with this message. This message is intended to help inform users and
cut down on redundant posts, which benefits everyone.
Please look at the attached list of ns Frequently Asked Questions.
If it answers your question, great! You're done.
If not, please RE-SEND your original message to [email protected].
A copy of your original message is included below for reference.
You will NOT have to do re-send your message every time you post, only
the FIRST time you send from a new account. The goal is to quickly
help new users find the FAQ (hopefully answering their question).
Thanks,
-John Heidemann

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 question to the mailing list (see below).
* _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
documentation, above), then start with an example program that is
most similar to yours (in the tutorial, or in tcl/ex or tcl/test
in the distribution), and then start changing things.
* _What should I do to compile ns to reflect my changes if I've
modified some .cc or .h files?_
go to ns directory and run "make" or "make depend; make"
* _What if I have a question that's not answered here?_
If you've checked the installation problems and bug fixes web page
(http://www.isi.edu/nsnam/ns/ns-problems.html) and there's no
answer to your question, you may want to post a question to the
ns-user's mailing list.
First, you should check the archive of the list at
http://www.isi.edu/nsnam/ns/ns-lists.html. Your question may
already be answered there.
If not, you may wish to post to the list. First you should
subscribe. Subscription instructions are at
http://www.isi.edu/nsnam/ns/ns-lists.html.
When posting bug reports to the list, please _always_ include
information including at least:
+ what version of ns you're using,
+ what operating system you're running on (not just Linux or
Solaris, but RedHat version 7.0 or Solaris 2.4---send us the
output of "uname -a"),
+ what specific behavior you see (if ns doesn't compile, what's
the specific error; if TCP does something strange, what
exactly did it do [send a pointer to a packet trace]),
+ what behavior you expected to see (if ns doesn't compile this
is obvious, but if TCP does something strange, why is it
strange, where is the TCP spec violated?),
+ pointers to your script detailed output files,
+ a statement that "yes, I've read the FAQ, ns-problems page,
and manual and I couldn't find the answer there" (or a
statement about why you didn't do that yet :-)
A reminder about mailing list etiquette:
+ Please check the web pages and list archives before posting
your question.
+ Please keep the body of your post to simple ASCII, not HTML.
+ Please do _not_ send large attachments (if what you have is
bigger than a few kilobytes, put it on a web page and send a
URL)
+ Before posting a question like "did people see my post" or
"the list seems down", please check the archives (you can
answer this question more accurately by checking yourself
rather than asking).
+ Please don't post subscribe/unsubscribe requests directly to
the list, send them to [email protected] (see the web page
mentioned above for details).

Hi,ns user and Padmaparna,
Sorry for disturbing every one, but I need the help urgently.
I install ns-allinone-2.1b8a on the Linux 7.0 red hat platform
recently.
After installation, I validate the ns, all tests are passed, but I found
there are some warning in the test results.One of these is listed as
follow,
==========================================================================
Running test wireless2:
../../ns test-suite-WLtutorial.tcl wireless2 QUIET

[suppressing additional MAC cache_ warnings]

All test output agrees with reference output.

=============================================================================
I would like to know how I can suppress this warning,since I do some
simulation on wired-cum-wireless secenario,which has the some waring when
I run it with ns.
Thank you very very much in advance!
p.s I try to sign on in the mailing-list,but failed.Sorry for disturbing.
With best Regards.
