[Click] nsclick promiscuous interface

[Bart.Jooris]

Hello,

Based on the information I found from Mike (November 2004 Archive) I added
a sniffer to the simple wired lan example (nsclick tutorial by Michael Neufeld).

This is the code of my Sniffer.click:

  // Sniffer
  //
  FromSimDevice(eth0,4096) ->
	ToDump(Sniffer)->
	Discard;
	
  Idle->
	ToSimDevice(eth0);	

I inserted this code in the tcl script after the node generator for loop

  set i 4

  set node_($i) [$ns_ node] 
  $node_($i) add-wired-interface $chan_1_ $netll $netmac \
    	  $netifq 1 $netphy 
*  $node_($i) setpromiscuous 0 1*
  $node_($i) random-motion 0 
  $node_($i) topography $wtopo 
  $node_($i) nodetrace $tracefd 
  [$node_($i) set classifier_] setnodename "node$i­sniffer" 
  [$node_($i) entry] loadclick "Sniffer.click" 


After running the simple wired lan example I opened the
Sniffer file with ethereal. There was only one entry, the arp broadcast :(

any ideas on this?

Thnx,

Bart.

 

Hello-
You can do promiscuous mode in nsclick, you just have to enable it from 
the tcl part of your scripts. For example, to make eth0 go promiscuous:

$node setpromiscuous 0 1
