Blue Box: The VoIP Security Podcast

Blue Box RSS feed dead - waiting for Feedburner to update its DNS

Ah, the joys of switching domain name providers. I transferred blueboxpodcast.com from one registrar to another last week shortly before the domain name was set to expire. Unfortunately, I made one serious mistake - I didn't check the DNS nameservers for the domain at the new registrar (GoDaddy) to ensure they were pointing to the new nameservers. They weren't... they will still pointing to the old nameservers. As a result, when the domain name expired at the end of the day on Friday, the web site was no longer available and had the message that the domain name had expired.

MANY THANKS to the couple of you who contacted me on Saturday to let me know about this!

So I fixed the web site yesterday morning so that "www.blueboxpodcast.com" pointed over to TypePad, where I host this site, and that all seems to be back in action. If you type in "blueboxpodcast.com" without the "www", it was going to a generic GoDaddy page but I've set up the forwarding now so that this should now redirect you to www.blueboxpodcast.com once the DNS propagation occurs.

What is still dead, though, is the RSS feed... which is rather annoying since that is what podcast subscription tools like iTunes use! In working through the issues this morning, it appears to be the issue that

Feedburner is not using the updated DNS information.

The Blue Box RSS feed, which is http://feeds.feedburner.com/BlueBox is somehow pointing over to the old page. Yet the base feed for this site, http://www.blueboxpodcast.com/atom.xml resolves perfectly fine and does have the RSS information. (Please don't switch to subscribe to that one... I do like the stats I get through Feedburner.)

So it appears that I'm waiting for FeedBurner to update its DNS. I've tried all sorts of options in the FeedBurner settings, including the "Resync Feed" but nothing works because it seems that it is unable to get to the new site (because of DNS).

I've filed a help request in the FeedBurner Google Group (which appears to be the only way to get help). Hopefully FeedBurner will age out its DNS info soon and the feed will be back in action.

What I find strange, though, is that I'm 99% sure that all the DNS records had a TTL of 1 hour (and I'm 100% positive the new ones do). So my question to FeedBurner is - if that is the case, why aren't they respected the TTL settings of the domains?

I'll update this post once I have more information.

Three years of Blue Box podcasts....

Today is a special day for me. It was three years ago on October 24, 2005, that Blue Box Podcast #1 was uploaded. It was an 11-minute episode where I talked about... Skype security, SIP security, IETF, VOIPSA and some other VoIP security news..... (Hmmm... sounds lot like our recent shows, too, eh?)

Jonathan Zar joined me a week later on Blue Box Podcast #2 and we've been going ever since. We've now produced over 112 episodes, had close to 245,000 downloads of our various shows, met some amazing people, learned a lot along the way... and hopefully helped you all learn a lot out there as well.

Thank you to all of you who have joined with us on this journey... whether you've listened to our show from the very beginning (and we know of a couple of you who have) or have only recently joined in... thank you!

And now... on to the next three years... :-)

Blue Box's 3-year anniversary coming up on Friday...

It was three years ago Friday, on October 24, 2005, that I uploaded Blue Box Podcast #1, an 11-minute show where I introduced the show, talked about VoIP security news (To no surprise, I was talking about Skype security!), some projects of VOIPSA and some other podcasts people might find interesting. A week later, on Halloween 2005, Jonathan joined me in Blue Box Podcast #2 and we were off and running...

Three years later... 84 main Blue Box episodes (with one more recorded) .... 26 Special Editions (with about 10 in the queue)... almost 250,000 downloads... we're still here and, with an admitted bit of a rough patch this summer, are still going along creating shows and enjoying what we do.

Jonathan and I are planning to record a 3-year show on this coming Friday, October 24th, and if you have any comments you would like us to include in that show, please do get them to us by the end of the day on Thursday, October 23rd. You can send them to us via:

• Email to blueboxpodcast@gmail.com
• Phone to +1-415-830-5439
• Phone via SIP to sip:bluebox@voipuser.org

The show started out 3 years ago as really an experiment in seeing whether or not podcasting could be used to reach out to very specific audiences... and it's been both fun, amazing and interesting to see how well it's done.

Thank you to all of you who have continued to listen and contribute over the years!

Show Content:

In this interview, I sat down with Eric Hernaez, CEO of Solegy, to talk about the OpenSBC Project and how it provides an open source implementation of a session border controller (SBC).  We talked about how OpenSBC came about, who is using it, how scalable it is and where users can learn more.  We also discussed Solegy, the company supporting the open source OpenSBC project and what they are doing. It was an enjoyable talk that really came about randomly when I met Eric near the press room at IT Expo in Los Angeles back in September 2007. We had been wanting to learn more about the OpenSBC project so I put my recorder on a table and we started talking.

More information about the OpenSBC project and other open source SIP-related projects can be found at opensourcesip.org.

Production assistance on this Special Edition was provided by Sergio Meinardi.
