I have a problem. Sometimes I'm slightly paranoid about computer security. Sometimes I wonder if the pages I visit are being logged somewhere when I'm on my university network. And when it comes to servers I manage, sometimes I wonder if I'm actually alone or not. Logs aren't enough, as someone clever enough may wipe their footprints after getting access to the server. If you want to reliably track break-in attempts, you'll have to log them outside your server, somewhere where your lurker won't be able to remove the traces. How about one of the many chat applications that are always running on my phone?
