Answer 1

Your above simulation ...

set val(chan) Channel/WirelessChannel ;#Channel Type 
set val(prop) Propagation/TwoRayGround ;# radio-propagation 
set val(netif) Phy/WirelessPhy ; 
set val(mac) Mac/802_11 ;# MAC type 
set val(ifq) Queue/DropTail/PriQueue ;# interface queue type 
set val(ll) LL ;# link layer type 
set val(ant) Antenna/OmniAntenna ;# antenna model 
set val(ifqlen) 50 ;# max packet in ifq 
set val(nn) 2 ;# number ofmobilenodes 
set val(rp) AODV ;# routing protocol 
set val(x) 500 
set val(y) 500 

set ns_ [new Simulator] 
set tracefd [open malicious.tr w] 
$ns_ trace-all $tracefd

$ns_ at 1.0 "[$node_(1) set ragent_] malicious"

... is very close to a copy of the classic "malicious.tcl" by Xuan Chen ( See aodv-malicious-examples-04.17.tar.gz https://drive.google.com/file/d/0B7S255p3kFXNRVBTU2JOUnpKclk/view?usp=sharing )

# $ns_ at 0.0 "[$node_(1) set ragent_] malicious"
$ns_ at 0.0 "[$node_(1) set ragent_] hacker"

The error ...

ns: _o40 malicious: (_o40 cmd line 1)

... can happen in two occasions : 1. No "aodv-malicious" was added to your ns-2.35 . 2. The wrong definition is used : In the most used patch, aodv-malicious_ns235.patch malicious is set as hacker (in aodv.cc). Which means the setting in the simulation script must be ...

$ns_ at 1.0 "[$node_(1) set ragent_] hacker"

( Other reason for the error : You could simply be using a wrong copy of the executable 'ns' for your command $ ns malicious.tcl ).
