I'm studying in University of St. La Salle, i am currently
studying in advance how to setup a server. I don't know anything about networking or linux but i want to learn, so bear with me if my question is stupid :). I'm just wondering if i still need to install a firewall to my
mini server (my computer, installed with a linux. it has an ethernet card connected to a hub with 2 modems connected to each slot. I am connected to a the internet).
When someone connects to one of the modem, do they still need to log in ? or are they automatically connected to the dialup network and to the internet? well, i want them to login first, i don't want any stranger wondering around my connections....do i still need the firewall?? in my understanding firewall are suppose to protect my modems from unauthorize entry..by requiring user to login.
