[Ethereal-users] tcpdump lines to use when capturing

[cplusplus@xxxxxxxxx]

Hello ethereal-admin!

I am trying to capture only smtp.

I have tried to use the tcpdump syntax
to capture only "smtp" but with no success...

I thought i could do it by entering:
ether proto smtp
but no such luck.. :/

Is it possible to catch only the smtp traffic?

Br,
