Linux Mandriva 2008のネットワークシミュレータNS-2 - namエラー：「既存のnamインスタンスに接続できません」

トピックはここから始まります---https://superuser.com/questions/525110/installing-network-simulator-ns-2-allinone-on-linux-mandriva

特定のエミュレータがあります -NS-2。

これは、ネットワークトポロジ、トラフィックソースと宛先の設定、すべての接続パラメータ（帯域幅、待ち時間、パケット損失確率、およびシミュレートされたシステムの他のいくつかのパラメータ）を記述するために使用できます。

にインストールしました。Linuxマンドレと2008効果がある

しかし、可視化することは不可能です。その理由は次のとおりです。到来の牙。

簡単な例を実装しようとしています（コードをもう一度繰り返します） -

ns-simple.tcl:

#Create a simulator object
set ns [new Simulator]

#Define different colors for data flows (for NAM)
$ns color 1 Blue
$ns color 2 Red

#Open the NAM trace file
set nf [open out.nam w]
$ns namtrace-all $nf

#Define a 'finish' procedure
proc finish {} {
        global ns nf
        $ns flush-trace
        #Close the NAM trace file
        close $nf
        #Execute NAM on the trace file
        exec nam out.nam &
        exit 0
}

#Create four nodes
set n0 [$ns node]
set n1 [$ns node]
set n2 [$ns node]
set n3 [$ns node]

#Create links between the nodes
$ns duplex-link $n0 $n2 2Mb 10ms DropTail
$ns duplex-link $n1 $n2 2Mb 10ms DropTail
$ns duplex-link $n2 $n3 1.7Mb 20ms DropTail

#Set Queue Size of link (n2-n3) to 10
$ns queue-limit $n2 $n3 10

#Give node position (for NAM)
$ns duplex-link-op $n0 $n2 orient right-down
$ns duplex-link-op $n1 $n2 orient right-up
$ns duplex-link-op $n2 $n3 orient right

#Monitor the queue for link (n2-n3). (for NAM)
$ns duplex-link-op $n2 $n3 queuePos 0.5


#Setup a TCP connection
set tcp [new Agent/TCP]
$tcp set class_ 2
$ns attach-agent $n0 $tcp
set sink [new Agent/TCPSink]
$ns attach-agent $n3 $sink
$ns connect $tcp $sink
$tcp set fid_ 1

#Setup a FTP over TCP connection
set ftp [new Application/FTP]
$ftp attach-agent $tcp
$ftp set type_ FTP


#Setup a UDP connection
set udp [new Agent/UDP]
$ns attach-agent $n1 $udp
set null [new Agent/Null]
$ns attach-agent $n3 $null
$ns connect $udp $null

しかし、エラーメッセージが表示されます。

再建しようとしています南、彼らが言うようにここ、私のremote-create-animator機能は次のとおりです -

AnimControl instproc remote-create-animator {trace_file args} {
    catch "array set opts $args"
    AnimControl instvar PORT_FILE_
    if [catch {set f [open $PORT_FILE_ RDONLY]}] {
        error "Cannot read server port from $PORT_FILE_"
    }
    set port [read $f]
    close $f

        puts -nonewline "Cannot connect to existing nam instance. "
    puts "Starting a new one..."
    $self local-create-animator $trace_file [join $args]

    #if [catch {set sock [socket localhost $port]}] {
    #   puts -nonewline "Cannot connect to existing nam instance. "
    #   puts "Starting a new one..."
    #   $self local-create-animator $trace_file [join $args]
    #} else {
    #   if {$trace_file == ""} {
    # puts "A nam instance already exists. Use nam <trace file> to view an animation"
    #       close $sock
    #   } else {
    #   global tcl_platform
    #   if {$tcl_platform(platform) == "windows"} {
    #       if [regexp {^(\\\\|[A-Za-z]:[/\\])} $trace_file] {
    #           set tf $trace_file  ;# Absolute pathname
    #       } else {
    #           set tf [pwd]/$trace_file    ;# Relative pathname
    #       }
    #   } else {
    #       if [regexp {^[~/]} $trace_file] {
    #           set tf $trace_file  ;# Absolute pathname
    #       } else {
    #           set tf [pwd]/$trace_file ;# Relative pathname
    #       }
    #   }
    #   puts $sock "CA $tf [join $args]"
    #   flush $sock
    #   close $sock
    #   }
    #}
}

しかし、何も変わらなかった。最近のお知らせは――"Cannot connect to existing nam instance. Starting a new one..."
