?Has anyone seen this before? The last time I noticed spurious activity like this, I thought a neighbor was playing pranks on me, and increased the security of my insecure wireless a bit. But there isn't actually any network activity I can detect. Any server that I'm running is liable to get scanned with fairly pointless requests at roughly the same time each day. The IP in the logs is almost always one assigned to my own computer, and not another on my network. There doesn't have to be any connection to the Internet or wireless, and Ethereal doesn't capture anything matching the logs. Avast and Spybot Search&Destroy don't find anything wrong on my computer.
Apache sometimes gets asked for something like "Nice ports,/ Trinity.txt.bak" except with several characters replaced by HTML entities.
