Blue Box: The VoIP Security Podcast

Blue Box is now on Twitter... and new shows *are* coming...

FYI, if you use Twitter, you can now find out when new shows are out and/or interact with Jonathan and I by following us at:

http://twitter.com/blueboxpodcast

And yes, new shows are on the way. I've been a wee bit busy with a recent job role change and Jonathan's had some crazy times on his end as well... but soon... real soon...

eComm 2009: Dan, Jonathan and Martyn together for the first time

Last week at the Emerging Communications Conference (eComm) 2009 in San Francisco, a remarkable event happened: Jonathan Zar, Martyn Davies, and I (Dan York) all wound up at the same place at the same time. Over the 3.5 years since we started Blue Box back in October 2005, Jonathan and I have met at events, Martyn and I have met and Jonathan and Martyn have met. But the three of us had never been together at the same place.

Now the particular place we met was a "Dev Dinner" hosted by (my employer) Voxeo after the end of eComm - and we had some great conversations along with the food. Martyn produced his camera and we did record the actual event:

Alas, it was too noisy there for us to do any actual recording, but it was great to have all three of us there. For those who may not recall the history, Martyn was one of our earliest listeners and is the person who provided both the image that we use for Blue Box (in iTunes, in the MP3 file, etc.) and also the music that we use for the intro and outro. He's also guest-hosted several times and contributed a couple of interviews over the years.

P.S. And yes, Jonathan and I will be getting some more shows out...

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!
