My system logs show that psad detects scans like this every minute.

psad: scan detected: -> udp: [53] udp pkts: 2 DL: 2

If the first address is mine, and the second address is my router, then this would be a scan coming from my computer, correct?

Is this anything to worry about?

What is the output for cat /etc/resolv.conf and nslookup server – jippie Oct 14 '12 at 9:36

Port 53 is DNS; nothing to worry about unless you peep in with Wireshark and find that the requests are for hosts you don't visit.
