I reinstalled ns-2.31 again, detailed steps:
1. tar -zxvf ns-allinone-2.31.tar.gz
2. cd ns-allinone-2.31
3. export CC=gcc-4.1 CXX=g++-4.1
4. ./install
then I follow your advice in the link:
http://www.linuxquestions.org/questi...rror-940388/#5
./ns test4maccon.tcl seems well, nam test.nam still appears "node i is not defined". However, when the topology script is changed into random.tcl, it nam well.

Concerning the node not defined problem:
1st define your nodes positions (x,y,z) coordinates 2nd Define node size. By that you'll be able to view them in nam without errors

Concerning the add-channel problem generated from start simulation button in CRCN GIU:
Just create your traffic,topo and other parameters and after that use your terminal to compile by ./ns yourfile.tcl , however I prefer not using that GUI.

i am using ubuntu 12.04
i installed ns2-2.31
i am getting an error in terminal


harsha@Harsha:~/ns2/ns-allinone-2.31/ns-2.31$ java -jar CRCN.jar

harshav you have to install java correctly and if you did otherwise you will get to CRCN problems, anyway I did not use the CRCN GUI try to write and run scripts of your calculation and drawings instead.

hi there,
is there any command to run throughput.awk that will relate to our throughput on my crcn?

as u mention before this:
echo | awk -f Throughput2007.awk

the results:
Average Throughput[kbps] = -0.00 StartTime=1000000.00 StopTime=0.00
Average Throughput[kbps] = -0.00 StartTime=1000000.00 StopTime=0.00

how can i fix this??
thank you in advance

# 20 .

Please try out one or more of the other *th* awk scripts:
avg_throughput.awk
avg_throughput(zigbee).awk
flow-thr.awk
genthroughput.awk
instantThroughput.awk*
instantThroughputStll.awk
Throughput2007.awk
throughput_newtrace.awk
thruput.awk

what about the nam?? i'm using nam1.13 for ns2.31..
but i dont understand the topology created by nam...the node represent for what and also the others

thank knudfl...

I've found some error while run this command:
./ns scenariowcett.tcl

You can attach scenariowcett.tcl to a new post, as scenariowcett.tcl.txt

thank you for your help knudfl..
thank god, the throughput.awk script that you gave me previously working perfectly..

i just want to know that the node below represent CR users or PR users?

-->if it represent the CR user, what command should i put to add the node that represent primary users?

it turn out like this after i enter tne command dpkg:
dpkg: requested operation requires superuser privilege

what should i do?
how about the node? is it for CR user environment only?

# 29 .

Sorry, it is of course $ sudo dpkg -i crcn-ns-2.31-ubuntu10_i386.deb


Which node ? What do you mean ? Please rephrase.
