Hi guys,

This is Madhu. I am working on tcp/ip for wireless networks on Linux Redhat, on an opensource tool NS2, since i am a beginner i am facing a problem in showing the simulations on the NAM window. i hav installed Ns all-in-one 2.34 package. i am writing the code in an editor window and save it as .tcl, then if i open it in the nam window, the file name which i saved is not existing , by this problem i am unable to open the created file to simulate it, can anyone help me to solve this problem.

Regards

not a networking problem. moved to Linux - Software. Please use useful and informative thread titles in future.

'nam' is not the tool for files.tcl . 'ns' is.
Please open a terminal window, and type : pwd <Enter>
The pwd command informs about your location. Probably /home/<your-user-name>/

If you saved file.tcl in say Documents/, either use a full path :
'ns Documents/file.tcl . Or use the cd command to change to
the directory with file.tcl : 1) cd Documents/ 2) ns file.tcl

The command 'ns file.tcl' may activate nam too.
Else run nam afterwards, to run a possible "out.nam" file : nam out.nam

And please try out some examples in ns-allinone-2.34/ns-2.34/tcl/ex/ ,
like 'ns ns-allinone-2.34/ns-2.34/tcl/ex/simple.tcl'
Or this one : cd ns-allinone-2.34/ns-2.34/tcl/ex/ && ns nam-example.tcl
( Etc. etc. : There are 400 examples ).

hi knudff,
i am doing wit the procedure which u mentioned but in the terminal window once i change the directory and type as ns file.tcl, i am getting it as ns command not found, so can u please tel me how can take the steps further.

1) cd ns-allinone-2.34/ns-2.34/ ; su ; make install
2) cd ../nam-1.14/ ; make install

The two 'make install' commands will copy 3 files to /usr/local/ :
a) The man page 'ns.1'
b) /usr/local/bin/ns
c) /usr/local/bin/nam
.... So now you can type ns or nam anywhere :
the command is in a system path and will always be found.

.

Hi,

I am doing with cd ../nam-1.14/;make install, but i am reporting with a message as permission denied, so what process can i do with. can u please send the complete prcess of writing the code and in which the file should be saved like .tcl or.tr or .nam, and how should i run it or simulate it in the nam window. how do we extract the saved code and simulate the file. please explain me.

Regards
Madhu

The 'make install' command requires root privileges.


1) su 2) Enter password 3) make install

HI,

yess i am getting the nam editor window once i do all the process, but wen i am trying to open the saved file the file is not shown in that path. i created my own folder named madhu, i have written the code in kedit and saved as example.tcl in madhu, one i open the nam editor window for simulation of that example.tcl i am unable to see the file example.tcl in nam window. like in nam window i go to file-open-home-madhu but in this madhu folder it shows all other files that i saved like pdf r any other document but i am unable to see the file saved as example.tcl . can you please tel me where am i doing mistake.

Regards
Madhu

Hi please give me some solutions sir, i am in trouble. i am unable to run the file.

Nam can not be be used for files.tcl. See post # 3.

About the 'ns' command : Some files.tcl must be run inside ns-2.34
in the folder relevant for that file.
Like : cd ns-allinone-2.34/ns-2.34/tcl/ex/ && ns nam-example.tcl

.

So now how can i run with the simulation, any other steps to be done

HI Knudfl,

Thanks alot, I got the simulation output. Thank you.\
