Cudo zvano internet

Petljam danas nesto sa serverima, mrezama itd i trebalo mi je da proverim nesto komandom tracerout. Kada sam video rezultat prilicno sam se zacudio! Jedan racunar nalazi se u AMRES-u drugi, moj kucni, na SBB-u.

Kada uradim traceroute iz AMRES-a ka kucnom racunaru… obidjem pola Evrope:

Nije mi bas najjansije zasto u jednom smeru paketi zalutaju a u drugom sve radi kao sto treba ocekivat. Nisam expert, ali rekao bih da na AMRES-u neke stvari ne funkcionisu bas najbolje? 🙂

ps. Sad sam primetio da SBB vec koristi .rs 🙂
