So far I have the following setup: hosts.deny:
ALL:ALL hosts.allow: ALL: my_work.domain My intention is to prevent everyone from the 'outside' from reaching my box. I do realize that anyone in my_work.domain would also be able to get at it. It is my understanding that this will prevent anyone not in my_work.domain from getting to my box with telnet, ftp, etc. Is this correct? Is this secure? If this is indeed correct could someone tell me why I would need/want a firewall and/or what benefit it would provide me over what I already have setup? More specifically how does a firewall differ from using the hosts.allow/hosts.deny files as I described above. Appreciate any advice on this... Bill
