SmartWiFi Security
I recently subscribe to smartwifi and guessed what I discover…..
I have 3 computers running Windows XP, Bayanihan Linux, and a dedicated Linux Router/Firewall. I got disconnected one day so decided to use my WindowsXP just to test the connection, after I release and renew my IP address I have also checked my Microsoft Network and as I have checked it I can actually see other workgroup computers and checked their shared folder… if this computer does not have a router/firewall installed one can easily checked or browse one shared folder and can easily get accessed to their home computer… I think smart should act on this security they are applying on their connection specially those computers connected directly to their network… if your just using one (1) computer directly connected to the their wireless router disable your windows file and printer sharing.. how to do this right click on LAN and go to properties and uncheck file and printer sharing … disable all shared folders and I my suggestion is to use a router that has a built in firewall link dlink or linksys if you have multiple computers or if you have a 486 computer or an ordinary Pentium class computer that you don’t use then you can set this as a router/firewall using linux… just go to coyote linux website and download the router/firewall and set this up on your computer… it runs only on a single floppy no monitor, hard drive or cdrom needed to run this system administration can be performed via web.. happy browsing or should I say hacking…..hehehehehe…
