DoS. Denial of Service. A DoS is usually used to stop people from accessing a network by flooding it with all sorts of crap. One way someone might DoS your server is by repeatedly pinging your server with large ICMP packets. Another form is apparently called smurfing... It's the same thing as repeatedly pinging except you spoof the victim I.P. and then pinging the broadcast address so every machine on the network is screwed. The last one is a SYN Flood where a server is sent a barrage of SYN packets requesting to start communication and won't communicate with any other requests until it can deal with the current ones. There's also DDoS which is just a DoS attack from multiple machines attacking multiple targets. So that's it. Gonna go cut my fingers on some Legos.
