The Valuable News weekly series is dedicated to provide summary about news, articles and other interesting stuff mostly but not always related to the UNIX or BSD systems. Whenever I stumble upon something worth mentioning on the Internet I just put it here.
Today the amount information that we get using various information streams is at massive overload. Thus one needs to focus only on what is important without the need to grep(1) the Internet everyday. Hence the idea of providing such information ‘bulk’ as I already do that grep(1).

CzeΕΔ, czy w FreeBSD jest taki konsolowy program jak “nemesis”? Mam jakieΕ anomalie w sieci i chciaΕbym sprawdziΔ, czy jakiΕ program nie podmieniΕ mi i nie podszywa siΔ pod jeden z moich adresΓ³w mac w sieci lan. Jest jakiΕ prosty sposΓ³b w systemach unix typu FreeBSD i Linux, aby namierzyΔ podmieniony adres mac? Mam taki program ntop ale on mi tego nie pokazuje.
