Planet-Lab.org traffic
by Drew Linsalata 23 Mar '12

23 Mar '12

At about 17:40 EDT today we started seeing traffic from planet-lab.orgnodes at 25+ US universities all directed at one of our hosting boxes. Its all ICMP and high port UDP stuff. Nothing terrible from what we can tell, but its triggering a constant stream of IDS alerts and auto-blocks. Not easy to configure for since the traffic originates from subnets all over the place, and the list of originating nodes is growing every few minutes. Its horribly annoying, and trying to determine the source using the tools provided on the planet-lab.org site is pretty much impossible as the search tool returns nothing at all times. Yes, we've opened a ticket with support(a)planet-lab.org already. Has anyone else had to deal with this, or is anyone connected to that particular project listening? Im all for academic projects, but the approach here is rubbing me the wrong way.

Looking for advice - Auditing zones on a set of name servers
by Landon Stewart 22 Mar '12

22 Mar '12

Hi Everyone, I'm looking for some advice here. I'm attempting to clean up a set of name servers and have a list of domain names that should not actually be hosted on those name servers. In some cases there are issues where there are actually no NS records in a domain but it should be hosted on those name servers. In some cases the name servers just aren't authoritative and the domain should be removed. The name servers are all djbdns, not that it matters a whole lot. I'm wondering if anyone knows of some tools that I can use other than homegrown ones that are a little more robust in terms of thinking of every little possible issue for or against a domain than I can think of. Of a list of domains that I marked for deletion some of them simply had little problems but should not be deleted (rather just have their NS records fixed). I also don't' want to pound on someone else's recursive name servers or even the root name servers trying to audit ours since that's not very nice. If anything I guess I could spread out the queries if I had the right tools. I wrote a quick script that looks up the NS records for a zone, then the A records for those NS records and checks the resulting IP addresses against a list of IP addresses that are our name servers. It's not quite doing all I need it to do since sometimes we are authoritative but there are no NS records or they are wrong. I'm also not sure beating on google's name servers is a good idea either so you should fill in your OWN recursive name servers instead f 8.8.8.8 and 8.8.4.4.
