Cannot create nodes in ns-allinone-2.30 using the 'set n0 [$ns node]' command
As per the ns2 tutorial http://www.isi.edu/nsnam/ns/tutorial/ to set up nodes the command set n0 [$ns node] is used, when I try this command I get an error, I can not also open the files including all the code in tutorials that you can use as a base point. The errors I get are as below for setting up the nodes:
% set ns [new Simulator] _o11 % set nf [open out.nam w] file4 % $ns namtrace-all $nf file4 % proc finish {} { global ns nf $ns flush-trace close $nf exec nam out.nam & exit 0 } % set n0 [$ns node] class Node: constructor failed: invalid command name "_o4 _o11" % set n1 [$ns node] class Node: constructor failed: invalid command name "_o4 _o11" To display the TCL files the following error occurs: % ns ns-simple.tcl error when calling class OldSim: ns-simple.tcl Any help would be greatly appreciated as I need ns2 for my dissertation urgently and I cannot find any way of resolving the issues. |
Welcome to LQ.
Please start here http://www.isi.edu/nsnam/ns/tutorial/nsscript1.html And have a look at this thread to see some of the examples put together into a workable tcl script. http://www.linuxquestions.org/questi...roblem-726993/ ..... ns-simple.tcl , have a look here http://nile.wpi.edu/NS/Example/ns-simple.tcl ... open it with 'ns ns-simple.tcl' and click the "Play button" in nam. http://nile.wpi.edu/NS/simple_ns.html ..... P.S.: I can't see where you got your file, or what made you write it in that way ..... a direct link may help. And please put code into code tags .... http://www.linuxquestions.org/questi....php?do=bbcode ..... |
