My networks (12 x /16) get scanned continuously for one thing or another.[1] Everyone who puts a machine on the network is required to take responsibility for configuring it securely, and they know that I'll cut them off at the first hint of trouble. On my home machine, I am perfectly capable of only configuring those services which I actually need. -GAWollman [1] According to my ARP table, there are scans going on right now on all but two of my networks. The other two are probably also being scanned, but those networks are subnetted and thus don't leave telltale traces in the ARP table.
