Thanks for help anyway, but,please read subj and body of my posting
again. The question is for comp.os.linux.networking, not for
*.broadband.voip.* or how.to.ebay.*. I know the diff between hub, switch
(managed,unmanaged,lowend/highend), router, etc. I'm also aware of arp
spoofing/overfloding/etc... As the box is running linux, so all
interfaces, links, routes, bridges, pppoatm, etc are created by linux
commands.So iss it possible to monitor/mirror a ether switch port having
root access to the box?
