Re: collectd as alternative to RTG for high-resolution polling and long term storage?
Be aware that collectd itself is a collection agent. It doesn't include (last I checked) a grapher. There are however a number of graphers out there to work with those RRD files, if you use that to store the data. I personally have been using collectd across hundreds of Linux systems, using rrdcached to a central collector and wrote my own grapher for that stuff I am interested int. Ulf.

Re: Dealing with auditors (was Re: We hit half-million: The Cidr Report)
The auditors VMware sent to us were just as bad. To ensure we weren't running "rogue" ESX(i) servers or WorkStation, they made us provide full arp/cam tables. Then a list of the virtual machines. "Oh look, this MAC isn't listed as one of your virtual machines". It isn't because it was running on virtual box or something like that.

Re: Comcast DNS Issue?
Is your issue that it gives out old DNS records? Because I am trying to track something down for an user on Comcast who is still getting the old IP of a VPN concentrator. The DNS records has a TTL of 30 minutes, yet a week later the end user is still getting the old IP. Haven't been able to get him to query 75.75.75.75 and 75.75.75.76 directly to see if he gets the IP from there.

Running 7.2.00 This is with code 07.2.00aT7f3. Had two units stacked together, rebooted/power cycled at least once and it worked.
