tcp Transferrate anzeigen

[peyote]

Wie kann ich unter linux den reinen tcp traffic anzeigen (also Transferrate) up und down?
Ein simples Kommandozeilenprogramm wäre mir am liebsten.

Danke erstmal, aber das ist doch der gesammte Traffic und nicht nur die reine TCP Nutzlast, oder?
Hintergerund ist der, dass ich über wlan verbunden bin und grade hier die TCP Nutzlast wesentlich kleiner ist als der Traffic über ath0.
