| netbios-ns | 137 | / | UDP(tcp) | NETBIOS Name Service | WindowsのWinsockが、NET-BIOS名（Windowsのクライアント名）を宣言したり・問い合わせたり・応答したりする際に、共通でこのポートが使用される。 Windowsはなーんもないときでも「おれは○○だー！」とクライアント名をLAN上に撒き散らすため、一部では「バカパケット」と呼ばれる。UDPだから許されるってもんだ。 Windowsマシンから どこかをNSLOOKUPすると、53番だけでなく、相手のこのポートにも問い合わせを行うため、自分のやったことがバレバレとなる。非常に悪名が高い。 |
