Welcome to LQ. http://www.linuxquestions.org/linux/rules.html

Please read the LQ rules : Short hand writing is not allowed.
And then use a readable English : I have no idea, what you ask.

Some more information is required to answer ...
http://www.catb.org/~esr/faqs/smart-questions.html

( 1. The Linux, you use : Debian 5 Lenny ? )
2. ns2 version, like ' ns-allinone-2.34 '.
3. The directory and files in question.
... Like ns-allinone-2.34/ns-2.34/tcl/xxx/xx.
4. The command, you are trying to use ?
5. The exact code used by that command ?
6. The error message ?
7. A link, an URL with info about the protocol in question. Link layer ?

With those things made clear, somebody may have an answer,
or can (may be) point to someone familiar with the protocols,
you are working at.

i am using ns 2.27..
in lenny 5.
ok, i resolved the problem.
but now, i want ns2.34 with LEACH routing protocol for sensor network simulation.
Can you help me in this matter......



thanks

LQ member @emtarik05 has ported the mit code to ns-allinone-2.34 :

Message from @debanga :
? Which version of ns-allinone-2.xx are you trying to compile ? ? ?


Old tcl , tk , otcl , tclcl cannot be compiled on Debian (or Ubuntu.)
The oldest for Debian = ns-allinone-2.27, using tcl etc. from 2.34.
The install instructions are here, post #3 :
http://www.linuxquestions.org/questi...10-a-782356/#3

'ns-allinone-2.26' : Any other Linux, e.g. Fedora or CentOS.
'ns-allinone-2.1x' : CentOS 3.9 only.
Please read post # 2 again : Says 'LQ Search' , "Tag Name" = ns2
( ns226 posts are tagged too.)

New message by email from @debanga :

'ns-allinone-2.29.3' .. Ubuntu 9.10 Karmic
 

Ref. post # 6

sudo apt-get install \
libx11-dev libxmu-dev libxmu-headers libxt-dev libtool g++-4.1

If you want to use nam-1.11 ( any nam can be used ) :
http://bugs.gentoo.org/attachment.cgi?id=161242
cd ns-allinone-2.29.3/tk-8.4.11/
patch -p0 < tk-8.4-lastevent.patch

Edit some 'Makefile.in' :
otcl-1.11/, line 7 : CC = gcc-4.1
tclcl-1.17/, line 40 : CC = gcc-4.1
tclcl-1.17/, line 41 : CPP = g++-4.1
ns-2.29/ , line 36 : CC = gcc-4.1
ns-2.29/ , line 37 : CPP = g++-4.1
nam-1.11/, line 44 : CC = gcc-4.1
nam-1.11/, line 45 : CPP = g++-4.1

Do 'make clean' in otcl-1.11/ and next delete the 'Makefile'.
Now ./install will work.
..

thnx for your help!

llType command invalid
 

guys the problem llType appears since the program has TAB space between them so remove those space and then try it and please try to type the program do not just copy form sites.

using nist-mobility and sip togather
 

Hi every body

I need to simulate a mobility scenario that needs MIH and SIP together. I installed ns2.27 on my Ubuntu 10.04 and installed ns2.27 on it, according to your good guides and finally I could install NIST SIP and RUI Prior SIP on it.
but when I want to install NIST MIH, I seen that it needs ns2.29 with gcc-4.1!!! I can't install ns2.29 and NIST MIH according above helps.
I become confused. What I must do for using both in one simulation. Can anybody help me, please!

fahimeh_ak, post # 12 : Please start a new thread.
( This one has poor formatting. ( Reported )).
And I will have a look at "ns2.29 and NIST MIH".
Also : Please provide links to NIST + MIH files
and to their documentation.

Regards, knudfl.

Hi Kudfl,
can you please clear which Makefile is to be deleted, as in otcl-1.11, there is Makefile.in and Makefile.vc.
Thanks

@ FFatima, post # 14 : Welcome to LQ.

Most often the command 'make clean', will also delete the Makefile.
May not happen with a couple of the 'ns-allinone-2.xx' applications.

But if there is no file by name 'Makefile', there is nothing to delete.

( Makefile is generated from Makefile.in . ( Makefile.vc : Probably for Windows©.))
