iftop-ワイヤレスUSBデバイスを選択する方法

ISPの切り替えを考えて、インターネットトラフィックを監視したいと思います。トラフィックを監視してログに記録したい。 iftopは良い選択肢のように見えますが、間違っている場合は訂正してください。

問題は、私のマシンがUSBワイヤレスカードを使用していることです。 iftopはデフォルトでeth0になります。ワイヤレスUSBカードトラフィックをリッスンするためにどのコマンドを使用しますか、またはワイヤレスカードのデバイス名を見つけるためにどのコマンドを使用しますか？

私はUbuntu12.04を実行しています、これが私のlspci出力です：

iftop -i wlan0あなたが必要なものを手に入れるはずです。

ifconfig -aは、システム上のすべてのインターフェースを表示します。通常、ワイヤレスインターフェイスはwlan0、wlan1など。

iftop: display bandwidth usage on an interface by Host

Synopsis: iftop -h | [-npblNBP] [-i interface] [-f filter code]
                               [-F net/mask] [-G net6/mask6]

   -h                  display this message
   -n                  don't do hostname lookups
   -N                  don't convert port numbers to services
   -p                  run in promiscuous mode (show traffic between other
                       hosts on the same network segment)
   -b                  don't display a bar graph of traffic
   -B                  Display bandwidth in bytes
   -i interface        listen on named interface
   -f filter code      use filter code to select packets to count
                       (default: none, but only IP packets are counted)
   -F net/mask         show traffic flows in/out of IPv4 network
   -G net6/mask6       show traffic flows in/out of IPv6 network
   -l                  display and count link-local IPv6 traffic (default: off)
   -P                  show ports as well as hosts
   -m limit            sets the upper limit for the bandwidth scale
   -c config file      specifies an alternative configuration file
