Hi,
im a beginner at ns2 and i need to use the emulator for my project.
i downloaded this example from the ns-manual
set ns [new Simulator]
$ns use-scheduler RealTime
set me [exec hostname]
set bpf0 [new Network/Pcap/Live]
$bpf0 set promisc_ true
set ipnet [new Network/IP]
set nd0 [$bpf open readonly fxp0]
$ipnet open writeonly
set filt "(not ip host $me)"
$bpf0 filter $filt
set a0 [new Agent/Tap]
$a0 network $bpf0
set n0 [$ns node]
$ns attach-agent $n0 $a0
$ns run
but i got the output:
warning: no class variable Scheduler/RealTime::adjust_new_width_interval_
see tcl-object.tcl in tclcl for info about this warning.
warning: no class variable Scheduler/RealTime::min_bin_width_
invalid command name "Network/Pcap/Live"
while executing
"Network/Pcap/Live create _o11 "
invoked from within
"catch "$className create $o $args" msg"
invoked from within
"if [catch "$className create $o $args" msg] {
if [string match "__FAILED_SHADOW_OBJECT_" $msg] {
delete $o
return ""
}
global errorInfo
error "class $..."
(procedure "new" line 3)
invoked from within
"new Network/Pcap/Live"
invoked from within
"set bpf0 [new Network/Pcap/Live]"
(file "rt3.tcl" line 4)
the same thing happens for the other emulation examples ive tried.The
simulation examples run fine.Ive downloaded and installed
ns-allinone-2.33.Please help me out.
Thanks
