iftop - como selecionar um dispositivo USB sem fio

Question

Eu quero monitorar meu tráfego de internet, pensando em mudar de provedor. Eu quero monitorar e registrar meu tráfego. iftop parece uma boa opção, corrija-me se eu estiver errado.

O problema é que minha máquina está usando uma placa sem fio USB. iftop será o padrão para eth0. Qual comando devo usar para ouvir o tráfego da placa USB sem fio ou qual comando devo usar para encontrar o nome do dispositivo da placa sem fio?

Estou executando o Ubuntu 12.04, aqui está minha saída lspci:

iftop -i wlan0 deve conseguir o que você precisa.

ifconfig -a mostrará todas as interfaces do seu sistema. Normalmente, as interfaces sem fio são wlan0 , wlan1 , etc.

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
