Nie wiem czy pisałem o tym, ale mimo to, że 99% czasu spędzam na Windows, to mam styczność praktycznie 100% z linuksem, a to za sprawą routera. Mój ruch sieciowy filtruje router z firmware na bazie linuxa:
Zastanawia mnie czy w dzisiejszych czasach kernel 2.4.18, taki jak jest w rutku, jest wystarczający by pełnic rolę FW, ale jeśli nie stosują nowsze, to domniemywam, że tak.
Jak to widzicie?
