Facebook Servers Pinging Home Users?

I’ve been playing around with splunk lately, and one thing I’ve noticed is that I am getting a lot of pings from a certain range of IPs. I block inbound ping at my firewall, but this was so persistent I got a little curious. Here’s the log exerpt that piqued my interest:



Jan 23 2012 22:02:17 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.63.186.228 on interface outside
Jan 23 2012 22:02:17 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.63.186.228 on interface outside
Jan 23 2012 22:02:16 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.63.186.228 on interface outside
Jan 23 2012 21:55:05 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.171.228.232 on interface outside
Jan 23 2012 21:55:05 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.171.228.232 on interface outside
Jan 23 2012 21:55:04 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.171.228.232 on interface outside
Jan 23 2012 21:45:58 brt-fw-01 : %ASA-3-313001: Denied ICMP type=8, code=0 from 69.63.179.30 on interface outside

That’s the trimmed output, but you can see a bigger set of logs if you’re interested.

So just who are these persistent pingers?

As you can see, both ranges are owned by Facebook. So the question of the day… Why is Facebook ping scanning me?!? Get your guesses in now, because I’m going to email their abuse address and see what they say. 😉

Online Automation – IfTTT

Just a quick note about a new service I think lots of my friends might find useful – If This Then That. It’s a service that let’s you drag-n-drop connections between events online. I’m testing it out right now with the following rules I added:

  1. If a new WordPress blog entry is posted, post a tweet to my Twitter account with the URL.
  2. If a new WordPress blog entry is posted, post a tweet to my Facebook with the URL.

Those two rules look like this in their simple, graphical, rule builder:

The IfTTT Dashboard

And in the detailed task editor:

IfTTT Task Editor

I’m hoping this really simplifies the growing web of online services I use to communicate online! You can see the list of services they support on their website under the list of Channels. If you try it out, let me know how it works for you and what creative uses you find for it!
