Welcome to posting to the ns-users mailing list!
We automatically send this message to every new person who sends 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).

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
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
* _How do I subscribe to the ns-users mailing list? How do I search
old list archives? I can't take any more---how do I get off this
list?_
