Having problem implementing blackhole and grayhole in ns2 on Ubuntu linux 11.04

Dear Sir,

I am new to ns2 and trying to implement blackhole and grayhole attacks in ns2 installed on Ubuntu 11.04 32-bit machine.

First of all i am getting the following error in running "ns blackholeaodv.tcl" OR "ns grayholeaodv.tcl"

Code:

invalid command name "Agent/rtproto/blackholeAODV"

while executing

"Agent/rtproto/blackholeAODV" instproc init args {

$self next $args

}

(file "blackholeaodv.tcl" line 19)

http://www.btechnos.com/2012/05/tcl-...blackhole.html

If i use the tcl file for blackhole available at above mentioned link and generating scenario file using "./setdest" and cbr file using "ns cbrgen.tcl" then it gives following error

Code:

num_nodes is set 20

Creating nodes...

Please guide me to resolve this problem.

The most versions of "blackholeaodv patch for ns2" do not implement a new "rtproto/...".

I.e. examples.tcl with "rtproto/.." : Either edit , or don't use the example.

blackholeaodv-btechnos.tcl http://www.btechnos.com/2012/05/tcl-...blackhole.html :
Works OK here.

Ubuntu 11.04 is no longer supported by Canonical. If you want to learn something new then you are much better of learning on a system that is supported.

@Knudfl

Thanks for your blackholeaodv examples.

But i want to ask where to put the file "blackholeaodv.tcl" which was made available with "blackhole.tar.gz" and has following contents:

Code:



# ======================================================================

# Default Script Options

# ======================================================================



set opt(ragent)                Agent/rtProto/blackholeAODV

set opt(pos)                NONE



if { $opt(pos) != "NONE" } {

        puts "*** WARNING: blackholeAODV using $opt(pos) position configuration..."

}



# ======================================================================

Agent instproc init args {

        $self next $args

}      

Agent/rtProto instproc init args {

        $self next $args

}      

Agent/rtProto/blackholeAODV instproc init args {

        $self next $args

}      



Agent/rtProto/blackholeAODV set sport_        0

Agent/rtProto/" set dport_        0



# ======================================================================



proc create-routing-agent { node id } {

        global ns_ ragent_ tracefd opt



        #

        #  Create the Routing Agent and attach it to port 255.

        #

        set ragent_($id) [new $opt(ragent) $id]

        set ragent $ragent_($id)

        $node attach $ragent 255



        $ragent if-queue [$node set ifq_(0)]        ;# ifq between LL and MAC

        $ns_ at 0.$id "$ragent_($id) start"        ;# start BEACON/HELLO Messages



        #

        # Drop Target (always on regardless of other tracing)

        #

        set drpT [cmu-trace Drop "RTR" $node]

        $ragent drop-target $drpT

        

        #

        # Log Target

        #

        set T [new Trace/Generic]

        $T target [$ns_ set nullAgent_]

        $T attach $tracefd

        $T set src_ $id

        $ragent log-target $T

}





proc create-mobile-node { id } {

        global ns_ chan prop topo tracefd opt node_

        global chan prop tracefd topo opt



        set node_($id) [new MobileNode]



        set node $node_($id)

        $node random-motion 0                ;# disable random motion

        $node topography $topo



        #

        # This Trace Target is used to log changes in direction

        # and velocity for the mobile node.

        #

        set T [new Trace/Generic]

        $T target [$ns_ set nullAgent_]

        $T attach $tracefd

        $T set src_ $id

        $node log-target $T



        $node add-interface $chan $prop $opt(ll) $opt(mac)        \

                $opt(ifq) $opt(ifqlen) $opt(netif) $opt(ant)



        #

        # Create a Routing Agent for the Node

        #

        create-routing-agent $node $id



        # ============================================================



        if { $opt(pos) == "Box" } {



            set spacing 200

            set maxrow 3

            set col [expr ($id - 1) % $maxrow]

            set row [expr ($id - 1) / $maxrow]

            $node set X_ [expr $col * $spacing]

            $node set Y_ [expr $row * $spacing]

            $node set Z_ 0.0

            $node set speed_ 0.0



            $ns_ at 0.0 "$node_($id) start"



        } elseif { $opt(pos) == "Random" } {



            $node random-motion 1



            $ns_ at 0.0 "$node_($id) start"

        }

        

}

Should i make any changes within this file. And also where to put this file in ns2.34?

# 4 .

All blackholeaodv examples can be located anywhere.
None of the scripts have any other dependencies than accompanied the cbr and scen files.

About the post #4 "blackholeaodv.tcl" from "blackholeaodv.zip" or similar :
Any location. Not really an issue, as the script can't be used.

P.S. : When you show error output (post #1) or code (post #4) :
Code tags must be used ..
