Faq Troubleshooting Installation Problems

The Network Simulator ns-2 Frequently Asked Questions (This FAQ is also on the web at httpwwwisiedunsnamnsns-faqhtml)

The mailing is is now subscriber only---please see the FAQ entry on How do I post to the mailing list Why was my post rejected for details

bull Where do I get ns

From the ns web site at httpwwwisiedunsnamnsnshtml and the download page httpwwwisiedunsnamnsns-testshtml

bull 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 httpwwwisiedunsnamnsns-buildhtmlstart

bull What should I do if I have trouble downloadingextracting ns

This question is answered in detail at httpwwwisiedunsnamnsns-problemshtmldownloading

bull 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

httpwwwisiedunsnamnsns-problemshtml 3 the archives of the ns-users mailing list httpwwwisiedunsnamnsns-

listshtml 4 post a bug report (see below) httpwwwisieducgi-

binnsnamreportbugcgi bull What do I do after I successfully build ns

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

bull Where can I find documentation for ns

All documentation is linked from the main ns web page httpwwwisiedunsnamns Documentation includes a tutorial (originally from Marc Greis) and a reference manual (ns notes and documentation)

bull 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-2tclex and ~ns-2tcltest

bull 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

bull How do I know that ns correctly implements these protocols

Ns has validation tests that cover many protocols see httpwwwisiedunsnamnsns-testshtml 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

bull Are there any contributedadditional protocols not in the main distribution

Yes please see the contributed code web page httpwwwisiedunsnamnsns-contributedhtml The mailing list archives can also be helpful (see below)

bull 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 tclex or tcltest in the distribution) and then start changing things

bull What should I do to compile ns to reflect my changes if Ive modified some cc or h files

go to ns directory and run make or make depend make

bull How do I subscribe to the ns-users mailing list How do I search old list archives I cant take any more---how do I get off this list

To subscribe or unsubscribe see httpwwwisiedunsnamnsns-listshtml The list archive is at httpwwwisiedunsnamnsns-listshtml

bull How do I post to the mailing list Why was my post rejected

As of June 2004 the ns-users lists allow posts from subscriber only If youre not a subscriber your posts to the list will be rejected (This is unfortunately necessary to dispose efficiently of spam manual filtering is too expensive) We realize that the list is high traffic so if you wish to post to the list without receiving messages on it please subscribe and select the no-mail option for your subscription

For details about the mailing list including mailing-list specific FAQ (for example what if youre subscribed but still cant post) please see httpwwwisiedunsnamnsns-listshtml

bull Did my post appear on the mailing list (Or why didnt my post appear on the mailing list)

See the httpwwwisiedunsnamnsns-listshtml web page for help debugging mailing list problems

bull What if I have a question thats not answered here

If youve checked the installation problems and bug fixes web page (httpwwwisiedunsnamnsns-problemshtml) and theres no answer to your question you may want to file a bug report or post a question to the ns-users mailing list

First you should check the archive of the list at httpwwwisiedunsnamnsns-listshtml Your question may already be answered there

If not you can post a bug report using the web form at httpwwwisieducgi-binnsnamreportbugcgi

If your question is NOT about ns implementation bugs you may wish to post to the list First you should subscribe Subscription instructions are at httpwwwisiedunsnamnsns-listshtml

Please note that mail sent to the list is publicly distributed and archived If you have concerns about your message being made public (spam harvesting of your address) please consider that before posting We cannot remove messages from reciepients mailboxes or the public archive after theyre posted

When posting bug reports please always include information including at least (the bug report form includes spaces for these)

o what version of ns youre using o what operating system youre running on (not just Linux or Solaris but

RedHat version 70 or Solaris 24---send us the output of uname -a)

o what specific behavior you see (if ns doesnt compile whats the specific error if TCP does something strange what exactly did it do [send a pointer to a packet trace])

o what behavior you expected to see (if ns doesnt compile this is obvious but if TCP does something strange why is it strange where is the TCP spec violated)

o pointers to your script detailed output files o a statement that yes Ive read the FAQ ns-problems page and manual

and I couldnt find the answer there (or a statement about why you didnt do that yet -)

Soo-Hyun Choi observed from posts to the list Sometimes I see this list is filled with the questions with 1) asked many times before 2) hardly understandable what this guy is asking 3) too easy to find an answer over a few clicks over the Internet 4) soliciting to do their homework in a simple way by asking in this list 5) easily seekable an answer by contributing a couple of hours of reading the ns-manual 6) etc etc

As many of us in this list are doing an advanced degree it would be suggested to read the following article in order to raise a usefulmeaningful question in a smart way httpwwwcatborg~esrfaqssmart-questionshtml

This is very good advice since asking the Right Question is very likely to get a goodhelpful answer while asking a question poorly For example think about how you would answer these two questions Ns doesnt work for me it crashes Help as compared to I get a segmentation fault when running test script test-suite-webcache on Mandrake 10 Linux The backtrace is on my web page at wwwsomeuedu~someone It looks like it passes in the on-line test suites but it fails for me Am I doing something wrong

A reminder about mailing list etiquette

o Please check the web pages and list archives before posting your question o Please keep the body of your post to simple ASCII not HTML o 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) o 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)

o Please dont post subscribeunsubscribe requests directly to the list use the lists information page (see the web page mentioned above for details)

Installation troubleshooting ns-allinone package

Note you may also want to consider tips under the entries for the individual packages below to see if your allinone installation problem is found there

Installation of ns-2292 fails on x86_64 platform

bull Description otcl-111 compilation fails in the following way

gt usrbinld skipping incompatible usrX11R6liblibXextso when gt searching for -lXext gt usrbinld cannot find -lXext gt collect2 ld returned 1 exit status gt make [otclsh] Error 1 gt otcl-111 make failed Exiting

bull Previous solution Find the path to the 64-bit libraries and modify the makefile (eg usrX11R6lib64)

bull New solution Use the ns-allinone-2293targz package

Precompiled NS2-234 binaries for OS X Leopard 105 Snow Leopard 106

You can download my precompiled package of ns2 for Snow Leopard Leopard at the following address

OS X Leopard 105

Lloyd Wood notes

gtIm trying to install octcl 113 on Mac OS X 1052 as part of the ns 232 allinone install

checking for X11 header files checking for X11 library archive checking for XOpenDisplay in -lX11 no cant find X library

Thanks to gier egeland and David Viera for the hints

configure --x-includes=DeveloperSDKsMacOSX104usdkusrX11R6include --x-libraries=DeveloperSDKsMacOSX104usdkusrX11R6lib make

worked for me to successfully configure and make otcl-113 tclcl-119 and ns-232 on Leopard

That also worked for configuring nam-113 but that failed at the linker stage bleating

Undefined symbols __TkCreateXEventSource referenced from _TkpInit in tkUnixInito

so I grabbed nam-1-20080222tar which failed with the same linker error

(I was using the available TclTk in the system but using the allinone compiled TclTk made no difference here)

I expect that the above will work for any Mac OS X 104 or 105 with XCode with the added X11 headers -theres a pkg on Leopard Install disc 1 The parallel MacOSX105sdk tree is pretty empty relying heavily on the base code in 104u (for universal on Intel and PowerPC) On 103 using directories under DeveloperMacOSX1039sdk may well work - that directory exists but the tree under it is mostly empty under Leopard

ns-2

ns-2 not building with gccg++ 432

bull Description the screen is filled with warnings such as

commonpacketh358 warning deprecated conversion from string constant to lsquocharrsquo

bull Solution Add this flag -Wno-write-strings to the CCOPT line in the Makefile eg

CCOPT = -g -Wall -Wno-write-strings

ns-230ns-231 do not build with gccg++ 41

bull Description Linking stage fails with error

usrbinld ns hidden symbol `__stack_chk_fail_local in usrliblibc_nonshareda(stack_chk_fail_localoS) is referenced by DSO usrbinld final link failed Nonrepresentable section on output collect2 ld returned 1 exit status

bull Solution Apply the following patch to configurein in otcl-112 or otcl-113

diff -uNr otcl-112configurein otcl-112-patchedconfigurein --- otcl-112configurein 2006-09-25 010237000000000 -0400

+++ otcl-112-patchedconfigurein 2007-04-12 114509000000000 -0400 -747 +747 Linux) SHLIB_CFLAGS=-fpic - SHLIB_LD=ld -shared + SHLIB_LD=$CC -shared SHLIB_SUFFIX=so DL_LIBS=-ldl SHLD_FLAGS=

then rebuild the OTcl configure script

otcl-113$ autoconf -f

You should now be able to build OTcl (and everything else) normally Thanks go to Chia-Yung Su for figuring this out and for providing a reference to a similar problem in a different program

bull Alternative To work around the problem install gcc-40 and g++-40 and use them to compile OTcl

otcl-113$ configure CC=gcc-40 CXX=g++-40 --with-tcl=tcl8414 --with-tk=tk8414

You can also use gcc-40 and g++-40 to compile everything This may be simpler than using 40 for just OTcl (as suggested above) Type the following before you start building the programs

export CC=gcc-40 export CXX=g++-40

ubuntu

if previous tips dont work and after the configurein tric do the following (source [1]) It solves the issue on edgy with

gcc version 412 20060928 (prerelease) (Ubuntu 411-13ubuntu5)

bull for otcl use configure then manualy edit Makefile8

- CFLAGS= -g -O2 + CFLAGS= -g -O2 -fno-stack-protector

bull for ns nam use configure then manualy edit Makefile82

- CFLAGS += $(CCOPT) $(DEFINE)

+ CFLAGS += $(CCOPT) $(DEFINE) -fno-stack-protector

ns-229 does not compile on Fedora Core 5 (FC5)

bull Description ns-229 release does not compile on FC5 bull Old solution This patch contributed by Qihe Wang

httpmailmanisiedupipermailns-users2006-May055811html bull New solution Use the ns-allinone-2293targz package if you just want to use

ns-229 release if you want to use current cvs snapshot apply Qihe Wangs patch to that

nam-1

bull Description Youve installed ns and run an example script and get this error

ns finishcouldnt excute namno such file or directory while excuting exec nam outnam amp (procedure finish line 7) invoked from within finish

bull Solution This indicates that you have not installed nam or the nam binary is not being found by the script Perhaps you need to add the path to the binary Make sure you have added the path to the nam binary to your shell variable $PATH (I am presuming you are using Linux and bash as you didnt specify) using the following export $PATH=$PATHpathtonambinary Note this will have to be done every time you start a new terminal as it only lasts as long as that particular session To make it permanent you will have to enter this line into either your bashrc or bash_profile (or similar) (Thanks to Matthew Jakeman for this note)

nam-112 does not compile on 64-bit platforms

bull Description nam-112 will not build on 64-bit platforms bull Solution This is an open issue

httpsourceforgenetpmtaskphpfunc=detailtaskampproject_task_id=122153ampgroup_id=149743ampgroup_project_id=45608

The current cvs directory (as of November 19 or later) contains code that will build on 64-bit machines but you may need to edit the Makefile (change lib to lib64 directories) since the autoconf code is not working just yet Here is a link to the daily snapshot of nam-1 httpwwwisiedunsnamdistdaily

Post-install troubleshooting

ns-2 builds but fails some validation tests

bull Description ns-2 fails some validation tests bull Solution ns-2 is known to have problems with some validation tests on certain

platforms due to 64-bit problems or floating point differences on different platforms If the particular validation test is not central to your work the error may be safely ignored Please consider reporting a bug if you find new validation problems

unexpected behavior or crash (segfault) after code extension

In order to determine why ns-2 does not work as you expect or or why it crashes you have to use a debugger like gdb to figure out what happened

If you have never worked with a debugger before it might look a little bit difficult at first but its an absolute necessity for any serious programmer to master it People on the mailing list wont be willing to help you unless you have not tried seriously to fix the problem yourself

To get you started there are some excellent tutorials on the Internet for both gdb (like [2] [3]) and ddd a GUI to gdb (PDF slideshow) Install either of them make sure you have enabled debugging symbols in ns-2 (see the relevant part in the user tips) and re-compile everything Afterwards start ns through the debugger pass your tcl-script as argument using set args ltpath to scriptgt and either choose a reasonable breakpoint or let ns-2 crash and watch the backtrace depending on whether after adding your code the simulator just does not work appropriately or crashes respectively When you managed to narrow down the responsible piece of code use the debuggers capabilities to investigate even further (print watchpoints change variable values etc) in order to fix the bug(s)

What makes things a little more complicated is the fact that ns-2 not only uses C++ but OTcl as well When the simulator crashes and leaves you with an OTcl backtrace try to figure out what happened by watching at that If that does not suffices and there is no valuable C++ backtrace take a look at the ns-2 debugging page to learn how to include and use the Tcl debugger Since its not as sophisticated as gdb you might want to consider setting debug 1 at different points within the Tcl simulation script first and see from what point on it crashes Apart from that the page tells you how to determine a nodes (string) name from C++ jump into Tcl space and use the tcl debugger from there before possibly returning to C++ space

when and how to write to the users mailing-list If you think you need to ask people on the mailing-list please consider the following prior to submitting

1 VERY IMPORTANT in general have you tried hard enough to solve problems you encounter yourself This includes (and goes beyond) reading anything possibly related to your problems as covered in the ns-2 manual this wiki and the ns-2 webpage

2 if ns-2 ceased to work properly after you made some changes please o read the wiki part about debugging first o get a book on C++Tcl andor search the web to solve common

progamming language problems 3 search the mailing-list archives exhaustingly (this is mandatory) 4 consider this very good advice in asking and receiving help How To Ask

Questions The Smart Way particularly o Use smart subjects httpwwwcatborg~esrfaqssmart-

questionshtmlbespecific o Dont flag your question as acircVœUrgentacircVV even if it is for you

httpwwwcatborg~esrfaqssmart-questionshtmlurgent

o Follow up with a brief note on the solution httpwwwcatborg~esrfaqssmart-questionshtmlfollowup

o Dont re-issue mailing list questions shortly after you asked initially 5 for compiling issues

o include compiler errors in English language using LC_ALL=C make o include complete error messages on the relevant parts (dont truncate

line numbers) o include part of code which errors relate to

Some problems when using ns-2 C++

How to callback to OTcl from C++ code For example In OTcl you have the object named object(i) and simulator object named ns In C++ you should use as follows Tclinstance()evalf( $object(d) operation d d d d src src des master object) You also can add when to execute this operation Tclinstance()evalf( $ns [$ns now] $object(d) operation d d d d src src des master object)

Older versions of ns-2 nam-1 tclcl and otcl This wiki page started maintaining troubleshooting information as of the releases of the following packages

bull ns-229 bull nam-111 bull otcl-111 bull tclcl-117 bull ns-allinone-2292

For troubleshooting older versions of these packages please see the following page httpwwwisiedunsnamnsns-problemshtml

The Network Simulator ns-2 Installation Problems Bug Fixes and Help This page has moved and can now be found here The below page will be maintained for reference to older versions

INSTALLATION PROBLEMS This section will hold installation problems weve heard about and possible fixes for them between releases In general these are fixes for nsotcltclcl installation problems

For TclTk-80 installation problems refer to TclTk installation info page

IMPORTANT If you experience problem when building a ns daily snapshot you probably want to update your otcl and tclcl to the most current snapshot as well Sometimes changes in ns will REQUIRE an updated tclcl If you are using nam with ns snapshot it is recommended that you update nam together with ns because ns may provide new visualization features which requires an updated nam

General Problems

bull Problem I cant download ns from your web site

Work-arounds First many people have successfully downloaded ns (unless youre the first person to get a brand new release) Odds are that the solution to problems downloading lie on your end make sure that your browser isnt compressing or uncompressing it for you try Netscape if youre using IE or try another program to download like GNU wget make sure you use (GNU) gunzip to uncompress it not PKZIP

If these tricks dont help you might also try getting it via FTP (from ftpftpisiedunsnam) instead of HTTP (from httpwwwisiedunsnamdist) If ftping try using a dedicated FTP client instead of a web browser and make sure you transfer in BINARY mode not TEXT

bull Problem I cant subscribe or unsubscribe to the mailing list I get error messages back like

bull gtgtgtgtgt This is a multi-part message in MIME format bull gt Command this not recognized bull gtgtgtgtgt bull gtgtgtgtgt ------=_NextPart_000_0013_01C008417A1B9BA0 bull gtEND OF COMMANDS

Solution Send simple text (ASCII) e-mail to the subscribe address not MIME Majordomo the mailing list management program we use cant handle MIME

bull Problem My posts to the mailing list are rejected Im even subscribed to it

Solution Please see the mailing-list FAQ

bull Problem I was successful in installation but I cant run the example script in in tutorial simpletcl When i tried to run it gives few errors like

bull use-scheduler command not found bull attach-node command not found bull

Solution you need to run the script by issuing command ns simpletcl and you should add ns directory to the environment variable PATH

bull Problem Ok but I still cant run simpletcl under the ~nstclex directory it gives an error saying

bull couldnt execute nam bull no such file or directory while executing exec nam outnam amp

(Also when I try typing the comamnd ns simpletcl and I get the error ns command not found)

Solution Well you need to add nam directory to the environment variable PATH or specify its location in the tcl script (PATH is part of Unix so if youre not sure how it works please consult a local Unix expert or search the web on unix PATH)

bull Problem To fix another problem it says to apply a patch file Whats that How do I do that

Solution To apply a patch file get the the patch program (it ships with Linux and FreeBSD or you can get it from ftpgnuorg Change into the directory with the source code you want to patch and type patch lt pathtopatch-filepatch See the patch(1) man page for details about what messages youll see

Bonus answer how to generate a patch file To generate a patch file use the diff program with the -u or -c option diff -u old-copy-of-filecc filecc (This requires that you have saved a copy of the file before you modified it)

bull Problem I tried to apply a patch but it failed For example I got messages like bull [rootsrn04 ns-227] patch lt newfipatch bull patching file Makefilein bull Hunk 1 FAILED at 25 bull 1 out of 1 hunk FAILED -- saving rejects to file bull Makefileinrej bull patching file Makefilein

Solution Patches will succeed when applied to the same version of code against which they were generated If the code has changed you will get error messages like hunk failed

Unfortunately there is no general solution to failed patches It could be that the underlying code changed so much the old patch will not work But it could be that there were minor changes to the basic code and you could apply the patch manually

Some hints if you want to try manually applying a patch If you want to try applying a patch by hand you need to understand what youre patching more or less If youre trying to patch a Makefile and you have no idea what a makefile is its very possible youll make an accidental error that prevents things from working But dont fear you can at least try and you can always read the

documentation about the make program and learn something In the worst case you have to undo what you did Also although you will need some clue about what youre doing you probably dont have to completely understand the code If you try to manually apply a patch you should study the patch manual page so you can understand the simple format that a patch file and a rej file use

If youre not willing or able to manually apply a patch you have one other alternative A patch file takes original code (call it X-orig) and changes it into new code (call it X-new) by applying the differences described in the patch Patches fail if the patch program cannot find whats described in the patch in X-orig So an alternative to manually applying the patch is to find different original code If you find the same original code the person who made the patch used you should get it to apply cleanly So for example if a patch was generated against ns-226 and it fails when applied to ns-227 you could get rid of your copy of ns-227 and go get ns-226 then apply the patch to that older version (Of course this approach has other problems since you may want other things that are only in ns-227 TANSTAAFL)

bull Problem When I run validate or one of the test suites I get these messages warning using backward compatibility mode and using backward compatible AgentCBR use ApplicationTrafficCBR instead Is my simulator broken

Solution No ns is not broken These are warning messages output by the test suites not errors (However if you get these messages from your scripts we encourage you to move to the newer APIs)

bull Problem I got the following error message during building OTcl bull creating cache configcache bull No configure file found in current directory bull Continuing with default options bull checking host system type alpha-dec-osf40 bull checking target system type alpha-dec-osf40 bull checking build system type alpha-dec-osf40 bull checking for gcc gcc bull checking whether the C compiler (gcc ) works yes bull checking whether the C compiler (gcc ) is a cross-compiler

no bull checking whether we are using GNU C yes bull checking whether gcc accepts -g yes bull checking for c++ c++ bull checking whether the C++ compiler (c++ ) works no bull configure error installation or configuration problem C++

compiler bull cannot create executables

Solution Your c++ compiler (with exact name c++) does not seem to work Check with your sytem admin

bull Problem I get linking errors when building ns or nam like bull Undefined first referenced bull symbol in file bull et_tclobject bull spaceoptns-allinone-21b6tclcl-10b9libtclcla(Tclo) bull ld fatal Symbol referencing errors No output written to ns bull collect2 ld returned 1 exit status bull Error code 1 bull make Fatal error Command failed for target `ns

(or other symbols that begin with et_)

Solution Build everything with gcc dont mix gccg++ and ccld (Insure that if you build any C++ code with g++ that you link with g++ and that theyre the same version)

(These very confusing errors are from gcc et is part of the run-time type checking This code is generated at load time gcc gets confused if you mix compilers)

bull Problem I get errors like this when building ns-allinone bull [rootlocalhost unix] make bull gcc -pipe -c -O2 -Wall -Wno-implicit-int -fno-strict-aliasing -

bull homevahidDesktopTemptk847generictkh573 parse error before Window

bull

Solution You dont have the development libraries for X11 installed on your system (see X11Xlibh No such file or directory)

Fix install the X11 development libraries How you do this is system-specific In Redhat-like Linux distributions make sure you have the X11 -devel packages installed (In Fedora Core 2 installing xorg-x11-devel will fix this specific problem in general you may need other -devel packages for libc X11 and Tcl)

bull Problem Validation under Windows does not work

Solution As of ns 226 the windows port uses Cygwin which should substantly reduce validation errors Please have a look at individual ns versions for specific details The following information is way outdated

First you need to download Cygwin as of 2000-06-22 at version 112 which provides GNU binary utilities for the Windows platforms You may also want to download pre-compiled Perl for Windows After youve got all these tools apply the following patch to ~nstcltesttest-all-template1 to get around the rn problem

NOTE Some of the test suites will fail on win32 platform As of Feburary 26 1999 snapshot of ns the following test suites fail

test-all-simple test-all-tcp test-all-red test-all-sack

test-all-schedule test-all-red-v1 test-all-sack-v1 test-all-v1 test-all-vegas-v1 test-all-ecn test-all-manual-routing test-all-intserv test-all-webcache test-all-srm

However all of them failed because of floating point rounding differences on win32 and on unix We will test current ns snapshots and update the results here Thanks to Christian Joensson for his enthusiasm in keeping providing the information and patches for many ns releases

IMPORTANT NOTE The cygwin release 132 currently available (as of 072001) which we installed in win2000 doesnt seem to have a functional awk utility A significant portion of the ns validation script uses awk so we tried to replace awk with perl but now the bash shell (another cygwin utility) didnot handle stdinstdout correctly So we were unable to validate the windows version (ns21b8a) in this platform We welcome any suggestion from windows users to help solve this problem

bull Problem The test suites and validation fail with errors like bull ns _o3 cleanup file5 sackB4 Syntax error in file

binraw2xg at bull line 43 next 2 tokens my( bull Syntax error in file binraw2xg at line 59 next 2 tokens bull translate_point( bull Syntax error in file binraw2xg at line 94 next 2 tokens bull translate_point( bull Execution of binraw2xg aborted due to compilation errors bull Cant locate 50010000000000003 in INC at bingetrc line

4 bull while executing

(where the key parts are syntax error near my( and cant locate 5001)

Solution Get perl5 andor make sure the programs in ~nsbin are invoking perl5

Nss configure checks for perl5 but apparently this check is not sufficient for many peoples systems Suggestions for improving the check are encouraged (it already works on our systems)

bull Problem Things built OK but dont run because of missing shared libraries (for example you get the message cant load library libotclso or fatal libotclso cant open file errno=2 [from Solaris]) or libotclso can not open shared object file No such file or directory

Solution Many systems require that you do something special when installing new shared libraries Shared-library loading is system-dependent so consult the

man page for ld(1) on your system On many systems the program ``ldd can be used to diagnose shared-libary problems

A couple of hints many systems require that you set the environment LD_LIBRARY_PATH to specify where to look for shared libraries So if (lets say) you get the above error with otcl shared library (libotclso) you should append the path to your libotclso (which typically would be in the directory you have installed and built otcl) to the LD_LIBRARY_PATH macro in your cshrc file Other systems require that you run ldconfig when using new libraries

bull Problem Ns (or otcl or tclcl) gets link errors when building with references to dlopen similar functions beginning with dl

Work-around You need to manually add the library for dynamic linking to nss Makefile Look in the Makefile for the line LIB= and add your systems library for dynamic linking (typically -ldl)

Solution Unfortunately nss autoconf support for dynamic linking isnt currently very good and we cant test ns on all the platforms on which its used This configuration is done in ~nsconfconfigureindynamic If you can adjust the code there to correctly detect your system well be happy to add your patch to our sources

bull ProblemWhile building ns it gets compiled but bails out with the following error message during linking

bull c++ -static -o ns bull tclAppInito randomo rngo ranvaro misco bull bull bull -lXext -lX11 -lsocket -lnsl -ldl -lm bull ld fatal library -ldl not found bull ld fatal File processing errors No output written to

ns bull Error code 1 bull make Fatal error Command failed for target `ns

SolutionThis error appears due to compiling with the static flag on In static mode ld selects only the shared object and archive files ending with a (unlike dynamic mode where files ending with either so or a are acceptable)

Thus you will need to either

o configure with static option explicitly turned off with --disable-static or o edit ns makefile to replace the value static for the macro STATIC with

blank (Dynamic mode is the default option) bull Problem Ns is running out of memory and segfaulting

Solution See the memory debugging tips section of the debugigng tips web page

bull Problem I want to simulate ATM networks in ns What should I do

Solution If you just want to treat ATM as a 155Mbs link for IP packets you can get a pretty good approximation by well making a 155Mbs link Or a better approximation by accounting for ATM framing and using a 135Mbs link

If you actually want to explore the interaction between ATM cells and IP packets or MPLS or something like that you may have to implement it yourself or pack up a third-party package

One user (thanks L) suggested in ns-users

httpfreebsd1lumsedupk~umairNSdocindexhtml (theres a mirror at httpwwweesurreyacukPersonalLWoodnsATM if you cant reach that)

Its for ns version 1 its third-party its unsupported youre on your own

Deriving an ATM node class for ns-2 would actually be one of the few cases where youd expect incompatibilities between the derived class and everything else and where the rest of the things ns simulates are _supposed_ to fail badly across it would make it easier to implement less testing required

bull Problem How do I properly reference the ns-2 simulatorin my papers

Solution

There are two answers to that question If you want to cite the software itself you can cite S McCanne and S Floyd ns Network Simulator httpwwwisiedunsnamns andor the manual Kevin Fall Kannan Varadhan and the VINT project The ns manual If you want something published in a refereed location [Breslau00a] Lee Breslau Deborah Estrin Kevin Fall Sally Floyd John Heidemann Ahmed Helmy Polly Huang Steven McCanne Kannan Varadhan Ya Xu and Haobo Yu

bull Problem What should I do if the ns executable has its modification time in the future when I re-start my machine after shutdown

Solution We recommend that you talk to your local sysadmin since this indicates a clock difference between the file server and the client (this has nothing to do with ns)

bull Problem When using nam I get the following error no display name and no $DISPLAY

Solution Start the X server using startx at the prompt Set the display environment variable using setenv DISPLAY my_hostname00 (if you are using cshrc) or export DISPLAY=my_hostname00 (if you are using sh or bash) This solution works for both cygwin and unix

bull Problem Some validation tests fail under Windows This is a carry-over from ns-228 (see below)

ns-228

bull Problem Some validation tests fail under Windows

SolutionCurrently on Windows XP SP2 and Cygwin 1512 only two test should fail -- newreno_rto_loss_ackf and the new smac-multihop test-suite Until now if your research direction involves these features its best to use ns under some kind of Unix

bull Problem When installing ns-allinone-228 in solaris there may be build problems

bull Solution Apply the following patch Reported and fixed by Qihe Wang

ns-227

bull Problem Ns doesnt build with gcc-34 (as ships in Fedora Core 3)

bull Problem I get segmentation fault while trying to simulate using DSR in dbugged version of ns-21b9 (ns-dbug-dsr-072202targz)

Solution The dbugged version of DSR expects CMUPriQueue instead of QueueDropTailPriQueue Hence change the older queue type in yr DSR simulation script to CMUPriQueue

bull Problem The newer version of DSR code in ns-21b9 (which has been ported from CMU) incurs a lot of packet drops (especially TTL drops) compared to the older DSR version in ns-21b8 Solution The higher no of TTL drops seen were due to forwarded packets that were looping between the DSRagent and the LL layer This happened becoz direction in pkt-hdrs was not correctly set to DOWN when DSRagent handed the pkt to the LL to be fwded to the next nodeAnother change made to the DSR code

is that DSR now uses a CMU version of PriorityQueue in place of the older version in ns This can found under ~nsqueuedsrqueuecchDownload ns-dbug-dsr-072202targz for the debugged version of the src code Note that since DSR now uses CMUPriQueue all dsr scripts previously using QueueDropTailPriQueue should be replaced with CMUPriQueue See dsr test scripts under tcltest for examples

bull Problem When trying to run a simulation of 1 wired node 1 base station and 31 mobile nodes (33 nodes in total) the simulator segmentation faulted This is because in simulatorcc the size of nodelist_ which is an array of all wired nodes (since next_hop info is generated based on the wired connectivity ) is not updated with value of nn_ which is the total no of nodes in the topology This bug was reported and suggested fix was provided by Donghua Xu SolutionApply the following patch to file ~nscommonsimulatorcc

Solution bcache only appears twice in aodvh and nowhere else So you can fix it by renaming bcache to something else (perhaps aodv_bcache) on those two lines in aodvh

bull ProblemI try to build ns-21b8 under windows but the compiler bails out with errors like

Solution There is a patched version of ns-src-21b8a-wintargz available that should build under windows Also please visit this page for other info about building under windows

bull Problem How do we use NS emulation on ns21b8 Solution NS emulation currently works on FreeBSD machinesand is being fixed for Linux machines Till then you can use emulation on ns21b7

bull Problem I had a problem compiling tcl832 in ns-allinone-21b8a The problem I had was that when compiling tcl the Makefile tried to generate tclStubInitc which is already in tcl832generic In order to generate tclStubInitc you need tclsh which is what I was trying to compile so it didnt work Reported by Michele C Weigle SolutionContributed by Lloyd Lim Tcl will try to regenerate tclStubInitc if it thinks its timestamp is earlier than that of tcldecls andor tclIntdecls To fix the timestamps just touch tclStubInitc and everything should compile normally

ns-21b6

bull Problem Some ns-21b6 test suites dont pass (test-all-monitor etc) when ns is built with tcl-83

Solution Two choices (1) get tcl-803 (2) update to a snapshot of ns-2 and tclcl after 17 August 2000 For additional details see this message to ns-users

bull Problem ns crashes (segfaults) with Tcl_ParseCommand() at the top of the traceback or test-all-vc or test-all-monitor fail

One cause for this is that Tcl_Eval was called on a read-only string (Tcl_ParseCommand changes strings in-place in tcltk-83) This is a problem in some systems where the C compiler makes string constants read-only

Heres the top of the traceback from test-all-monitor

0 0x4012f1d7 in Tcl_ParseCommand () from usrliblibtcl83so 1 0x40130228 in Tcl_EvalEx () from usrliblibtcl83so 2 0x4012ff5e in Tcl_EvalTokens () from usrliblibtcl83so 3 0x401302a2 in Tcl_EvalEx () from usrliblibtcl83so 4 0x40130541 in Tcl_Eval () from usrliblibtcl83so 5 0x400fa063 in Tcl_GlobalEval () from usrliblibtcl83so 6 0x8114c97 in Tcleval () at genptypescc297 7 0x805eb87 in Agenttrace (this=0x83df338 v=0x83df57c) at agentcc282 8 0x8063f90 in TcpAgenttrace (this=0x83df338 v=0x83df57c) at tcpcc320 9 0x81161e9 in TclObjecthandle_TracedVar () at genptypescc297 10 0x811671f in TclObjectdelay_bind () at genptypescc297 11 0x8063412 in TcpAgentdelay_bind_dispatch (this=0x83df338 varName=0x83dd4c8 cwnd_ localName=0x83dd4c8 cwnd_ tracer=0x83df338) at tcpcc231

This problem has been observed on Linux systems running RedHat 70 (ie tclcl-83 and gcc 296) Probably it appeared there because either tclcl-83 changed Tcl_ParseCommand or gcc 296 changed string constants to be read-only by default

Solution Update to a tclcl snapshot after 17 August 2000 (or the 10b10 release whenever that happens)

Other work-arounds change your compiler to make string constants writable (in gcc add -fwritable-strings to CFLAGS and LDFLAGS)

As a work-around set the environment variable CC to gcc and CXX to g++ (setenv CC gcc setenv CXX g++) before configuring ns

In the next release of ns it will prefer gcc to cc when both ar available hopefully fixing this problem

bull Problem nam crashes when running the wireless examples in Marc Greiss tutorial

Solutionthere was a bug in hierarchical routing for wireless its fixed in the snapshot after 1252000

ns-21b5

bull Problem Compiler errors on htonl (occur on DEC Unix Debian Linux (but not RedHat) etc)

Solution Change the

if defined(hpux) || defined(sun)

defined in traffictracecc (around line 35) to be

if 1

(always) Eventually autoconf should figure this out

bull Problem On win9598NT ns compiles but does not run Doing a Simulator info instprocs shows nothing

Solution Comment out line source ns-autoconftcl in tcllibns-libtcl Because that file does not exist under win32 platforms the process that embedding tcl scripts into ns is aborted (Reported by David Lalla) This can also be solved by the following patch to bintcl-expandtcl

bull Problem Linker reports an error bull Undefined first referenced bull symbol in file bull _RENAMED

Solution Upgrade your TclCl

bull ProblemCompiling programs under indep-utilswebcache-conv on platforms other than FreeBSD or BSD44 systems will raise unresolved symbols heapsort and strsep

Solution Apply the patch to webcache-conv Or download ns snapshots after July 9th 1999

bull Problem If you run with assertion on (wo flag -DNDEBUG at compile)some assertions fail

bull Problem The wireless example script ~nstclexwirelesstcl when run with the DSR or DSDV routing option raises errors and then bails out with messages like

bull dfu ran off the end of a source route (for DSR) or bull dfu invalid UID etc

Solution Go to ns-build page for a special ns snaphot having the debugged version of CMUs wireless module in ns

ns-allinone-21b5

bull Problem When installing ns-allinone or ns I get an error message that includes

configure error can not run test program while cross compiling

For example

loading cache configcache checking for ranlib ranlib checking whether cross-compiling yes checking for BSDgettimeofday no checking for gettimeofday no checking for gettimeofday declaration missing checking for -linet no checking for neterrnoh yes checking whether char is unsigned configure error can not run test program while cross compiling tcl804 configuration failed Exiting

Solution You most likely have a gcc installation problem on your computer Please check gcc and try again (Also this is an error in tcl not in ns For other errors in tcl you may find help from Scriptics)

bull Problem When I went to install the ns-allinone-21b5 on Redhat 60 with Linux kernel 225-15 I got an error during compilation for tcl804

bull generictclPosixStrc In function `Tcl_ErrnoId bull generictclPosixStrc340 duplicate case value bull generictclPosixStrc328 this is the first entry for

that value bull bull generictclPosixStrc In function `Tcl_ErrnoMsg

bull generictclPosixStrc787 duplicate case value bull generictclPosixStrc775 this is the first entry for

that value bull bull make [tclPosixStro] Error 1 bull tcl804 make failed Exiting bull

Solution the compiler was complaining that the defined ENOTSUP and EOPNOTSUPP values in different case statements had the same value These statements are not defined the same in the ns-allinone package but if you look in usrincludebitserrnoh you will find the following statement

define ENOTSUP EOPNOTSUPP

so ENOTSUP is defined to the same value as EOPNOTSUPP in Linux Note this may not be true with different Linux kernel versions The solution to work around this is to

ifdef ENOTSUP case ENOTSUP return ENOTSUP endif ifdef ENOTSUP case ENOTSUP return operation not supported endif

comment out both of the above statements in tclPosixStrc They should be around lines 328 and 775 respectively

bull Problem ns-allinone fails to detect the correct version of tclsh ie tclsh80 As a result the installation script fails or worse finds an out-of-date tclsh in the directory which could cause some malfunctioning in the future

Solution

1 Download this patch and place it at your allinone directory 2 Apply the patch by typing patch -p lt ns-allinone-21b5patch 3 Remove configcache from your OTcl TclCl ns and nam directories 4 Re-install

bull Problem Ns doesnt generate nam traces for user-installed error modules Reported by Sarah Liu

Solution Add the following patches to tcllibns-libtcl and tcllibns-linktcl Note that these patches are against the current snapshot (ns-lib version 1139 and ns-link version 140) If you failed to apply them try download the current snapshot or use the context to apply these patches manually Previously there are two major OTcl methods to install a loss module in a simple link Simulatorlossmodel and SimpleLinkerrormodule These two methods insert an error module BEFORE the queue module in a link Simulatorlossmodel only inserts a loss module and is not capable of producing any traces (neither ns nor nam) for packet drops SimpleLinkerrormodule is able to produce ns and nam traces however the nam trace can only be visualized using nam snapshots after March 3rd 1999 After these patches both methods have identical effects but a new nam is still required In addition two new OTcl methods are added Simulatorlink-lossmodel and SimpleLinkinsert-linkloss These two methods insert an error module AFTER the queue module Their traces can be visualized by both the old nam and the new one Patch for ns-libtcl

bull bull sh tclsh80 not found bull bull Error code 1 bull bull make Fatal error Command failed for target genversionc

Reported 16 Dec 1998 by Raed Sunna

Solution There is a bug in ns-21b4s configure it only remembers that it finds tclsh80 not the complete path to it This will be fixed in tonights ns and nam snapshots for now the work-around is to manually edit the Makefile and specify the path to tclsh on the line that begins TCLSH =

bull Problem I cant compile embedded-tclcc (for example I get the message CCembedded-tclcc line 1 compiler limit exceeded lexical token too long on HP-UX 1020)

embedded-tclcc contains tcl code as one long string Some compilers (like yours) cant handle strings that are so long

Solution (choose one or the other)

o install gcc OR o rebuild tcl2c++ with TCL2C_INT defined then regenerate embedded-

tclcc with the new tcl2c++ (by deleting it and typing make after putting the new tcl2c++ in your path)

Heres the patch for HP-UX

bull Problem NS breaks on trying to use single level of hierarchy for hierarchical routing

Solution Apply patchfile hierpatch to remove the above bug

bull Problem mem-traceh doesnt compile or ns fails to link because of errors about getrusage

Solution Ns-21b4 and snapshots after 15-Sep-98 should autodetect getrusage Upgrade to those versions Work-around Comment out lines in mem-traceh which reference getrusage andor sbrk until things compile (This will disable memory monitoring but basic ns will still work)

bull Problem Static library of tcl-debug v17 on FreeBSD still contains symbols required by the dynamic libraries (crt0o) This is caused by compiling o files using -fpic and using those o files to build static library

3738c37 lt CFLAGS = DBG_CFLAGS lt SHCFLAGS = DBG_CFLAGS DBG_SHLIB_CFLAGS --- gt CFLAGS = DBG_CFLAGS DBG_SHLIB_CFLAGS 8587d83 lt SHCFLAGS_INT = $(MH_CFLAGS) $(CPPFLAGS) $(SHCFLAGS) lt lt SUFFIXES so 9192d86 lt cso lt $(CC) -c $(SHCFLAGS_INT) $(HDEFS) $lt 96d89 lt SOFILES = Dbgso Dbg_cmdso 114c107 lt $(DBG_SHARED_LIB_FILE) $(SOFILES) --- gt $(DBG_SHARED_LIB_FILE) $(OFILES) 116c109 lt TCL_SHLIB_LD -o $(DBG_SHARED_LIB_FILE) $(SOFILES) --- gt TCL_SHLIB_LD -o $(DBG_SHARED_LIB_FILE) $(OFILES)

Solutions

1 Download nam-snapshot from ns website or 2 Delete the line from your nam tracefile

(If youve done these and the problem persists check for old versions of nam in your path)

Solution This error suggests you upgraded ns without upgrading tclcl The recent ns release requires the current releases of otcl and tclcl

bull ProblemThe script tclextest-suite-intservtcl fails as does anything using the IntServ functionality SolutionThis patch to ns-libtcl fixes the problem

bull ProblemMulticast code breaks because the interfaces were not installed properly typically with an error message that goes as follows

bull omcc bull randomcc In function ìnt random() bull randomcc50 new declaration ìnt random() bull usrincludestdlibh198 ambiguates old declaration `long int

random() bull make [randomo] Error 1

Solution There seems to be differences in Linux definitions of random The Right Thing is to have autoconf detect the type of random but (since Ive not done that before) thats low on the priority list right now (code contributions are welcome of course---it should be easy to do this in autoconf)

Another approach would be to use an define which differs between Debian and RedHat I dont know of such a define

Until its fixed the Right Way this patch should work around the problem

bull Problem Ns doesnt write v events into nam trace files in correct format (without -t) It occurred in ns-allinone and has been corrected in daily snapshots

bull Problem Ns doesnt automatically find otcl-10b2 or tclcl-10b5 when running configure (Reported by Larry Wood)

Solution As a workaround configure --with-otcl=path_to_otcl and --with-tclcl=path_to_tclcl This is a bug which will be fixed in the next ns release

bull Problem Cannot find conf subdirectory in the ns-21b2 release

SolutionThe nsconf directory was inadvertently not added to the distribution list for ns-21b2 release The conf directory contains files consisting mainly of autoconf rules which are used during configuration for ns (looking for tcl tclcl otcl perl etc) Normally these files are believed to of no consequence to the functionalities of ns However if you want to take a look at these configuration files or play around with them they are available in a tarred format called ns-2conftar

bull Problem NS gets compiled fine but give the error ``Simulator not found when run

(A more specific error message)

[rdvomocha ex]$ ns rctcl invalid command name Simulator while executing Simulator create _o1 invoked from within catch $className create $o $args msg (procedure new line 3) invoked from within new Simulator (file rctcl line 10)

Solution Make sure you have tclsh in your path or change the Makefile to specify where tclsh is or generate genns_tclcc by hand (look at the Makefile for how) This problem often happens when genns_tclcc is incorrectly generated and can be deteced by that file being less than 1KB in size (it should be longer than 300KB) This error often occurs on FreeBSD where tclsh is installed as tclsh80

This problem should be fixed in ns-21b2

XGraph

bull Problem When trying to execute xgraph one gets the error cannot open display

Solution From the shell set the DISPLAY variable For example from bash one can do it with

export DISPLAY=machine00

bull Problem With RedHat Linux 60 or later xtbc fails to compile with the error

xtbc50 macro `strcpy used without args

Solution Apply the strcpy patchxgraph_strcpy_macro patch

bull Problem Using gcc 281 on HP-UX 1020 xgraph failed to compile

Solution Removing from lines 166 and 167 of xgraphh (Fixes provided by Fion Lee)

bull Problem Xgraph fails to build with errors about function mismatches in declarations of sprintf

Solution We have patches to fix three problems with xgraph more Posix-friendliness (fixes a build problem under Linux and probably elsewhere) disable animation (works around a bug with movedraw commands) typo fix (fixes a typo found by Patrik Fors)

Tclcl-10b13

bull Problem Tclcl doesnt build against gcc-34 (as in Fedora Core 3)

Solution Fixed in current CVS Apply this patch

--- tclclh~ 2003-07-29 112450000000000 -0700 +++ tclclh 2004-12-10 085534692584936 -0800 -458 +458 include tclcl-configh -include tclcl-mappingsh include tracedvarh + tclcl-mappingsh included below AFTER definition of class Tcl struct Tk_Window_ -1586 +1588 Tcl_HashTable objs_ +include tclcl-mappingsh + class InstVar class TclObject

Tclcl-10b9

bull Problem When configuring tclcl it searches for an outdated version of OTcl (10a4)

Solution Apply this patch to tclcl-10b9configure

Tclcl-10b8

bull Problem Compiling TclCL 10b8 results in a warning or an error about TclObjectenum_tracedVars() does not return a value

SolutionApply the following patch to Tclcc

--- Tclcc~ 19990224 190449 +++ Tclcc 19990224 191807 -3556 +3557 for ( var = 0 var = var-gtnext_) if (var-gttracer()) var-gttracer()-gttrace(var) + return TCL_OK int TclObjecttraceVar(const char varName TclObject tracer)

Tclcl-10b6

bull ProblemDouble-free bug in Tclcl-10b6 You have random crashes in ns particularly after you have destroyed objects

SolutionApply the following patch tclcl-10b6patch

Otcl (general)

bull Problem Im building OTcl from source and it complains with an error like bull gcc -c -g -o2 -DNDEBUG -DHAVE_STL -DUSE_SHM -I -

Ihomevijaytk832generic -Iotclc2120 bull tclInthNo such file or directory bull make [libotcla] Error1

Solution OTcl needs the file tclInth and tclIntDeclsh from the source code to Tcl If youre building OTcl on a platform with a binary installation of TclTk you must get these header files from the matching source code for your version ot TclTk

Otcl-10a3

bull Problem The OTcl test suites crash after the line PASSED objectvariables

Solution None yet Ns doesnt exercise otcl autoloading so fixing this bug is a very low priority

bull Problem OTcl 10a3 doesnt compile with tcl 803 and 804 it complains about unknown variable isArg

Solution Add the following patch to otclc

--- otclc~ 19980723 172803 +++ otclc 19980907 185343 -7637 +76311 Tcl_ResetResult(in) while (args = 0) if TCL_MAJOR_VERSION gt= 8 +if TCL_RELEASE_SERIAL gt= 3 + if (TclIsVarArgument(args)) +else if (args-gtisArg) +endif endif Tcl_AppendElement(in args-gtname) args = args-gtnextPtr

bull Problem You have error while compiling otcl which bails out with something like the following message

bull cc -c -g -DNDEBUG -DUSE_SHM -I -Itkboxinclude bull -Itclboxinclude -Iinclude otclc bull otclc line 1102 syntax error before or at bull otclc line 1105 undefined symbol co bull [snip]

Solution Apply the following patch as a workaround to otclc

Otcl-096

bull Problem OTcl-096 does not compile with tcltk-80 bull otclc In function `ListProcArgs bull otclc654 Àrg undeclared (first use this function) bull otclc654 (Each undeclared identifier is reported only

once bull otclc654 for each function it appears in) bull otclc654 àrgs undeclared (first use this function) bull otclc654 structure has no member named àrgPtr bull otclc655 parse error before ìnt bull otclc661 ì undeclared (first use this function) bull otclc In function `ListProcDefault bull otclc684 Àrg undeclared (first use this function) bull otclc684 àp undeclared (first use this function)

Solution Get otcl-10a2 or later from the ns-build web page You will need access to the tcltk-80 sources to configure and compile otcl Please remember to build OTcl first before proceeding with building TclCL and ns

Intel Linux systems

bull Problem Validation tests that pass on machines running FreeBSD and Solaris but give different results and therefore do not pass on Intel Linux machines

Solution Our current understanding is that because Intel Linux doesnt use IEEE arithmetic floating point operations can give different results on Intel Linux machines than on other systems that do use IEEE arithmetic Our fix for this portability problem so far in NS has been to make liberal use of EPSILONs (or in our case SMALLFLOAT) for example to say ìf (oldrate_ + EPSILON lt rate_) instead of ìf (oldrate_ lt rate_) This issue is addressed in more detail at the FAQ on Frequently Asked Floating Point Questions Our assumption is that even with the liberal use of EPSILONs in floating-point arithmetic we will continue to have portability problems for NS on Intel Linux machines

bull Problem When installing Tcl804 under RedHat 6061 the compilation of TclPosixStrc may fail due to a conflict between ENOTSUP and EPROTONOTSUPP

Solution Change the following lines (339 and 786) in TclPosixStrc from

ifdef EOPNOTSUPP

to

if defined (EOPNOTSUPP) ampamp (defined(ENOTSUP)||(EOPNOTSUPP = ENOTSUP))

bull Problem Installation of ns emulator nse on Linux fails

Solution Please download the lastest snapshot of ns

Other Problems

bull 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-2tclex and ~ns-2tcltest

bull 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

bull How do I know that ns correctly implements these protocols

Ns has validation tests that cover many protocols see httpwwwisiedunsnamnsns-testshtml 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

bull Are there any contributedadditional protocols not in the main distribution

Yes please see the contributed code web page httpwwwisiedunsnamnsns-contributedhtml The mailing list archives can also be helpful (see below)

bull 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 tclex or tcltest in the distribution) and then start changing things

bull What should I do to compile ns to reflect my changes if Ive modified some cc or h files

go to ns directory and run make or make depend make

bull How do I subscribe to the ns-users mailing list How do I search old list archives I cant take any more---how do I get off this list

To subscribe or unsubscribe see httpwwwisiedunsnamnsns-listshtml The list archive is at httpwwwisiedunsnamnsns-listshtml

bull How do I post to the mailing list Why was my post rejected
