Hello Anthony! Thank you for the help. I was able to successfully install and run Squid. Thank you to all the help I got from this group!
Yes I didn't install any DNS on my server. Now for the firewall... I am still thinking whether to do it the hard way (a friend of mine lent me a book in iptables today) or get the shorewall firewall and make things easier. I just got a basic rule right now. Block everyone else except me. Funny thing happened... I even blocked myself a while ago. Had to run to the server room and change all the config. Again, thank you for the help folks! I really appreciate this. Especially on the recent attacks on windows servers. I want to protect not only the linux servers but also the windows users.
