I have a fxp0 (Interl 100 Pro+) NIC and I have no cable attached to it as I am setting up the local LAN at home now. I wanted to test a simple ping on the localhost and watch with tcpdump. I got no response. This got me curious, because as far as I know, a ping to localhost never leaves the card and should thus be seen by the tcpdump. Or does tcpdump, when listening on a NIC, only pick up ethernet frames which have been sent over the wire? Thanks for any hints/enlightenments... --- Jeroen Ruigrok van der Werven A veil of smoke is what I am, asmodai(at)wxs.nl I wait and I wait...
