More instructions for changing your DNS settings

by John Roberts on Jul 31st, 2006

When we launched three weeks ago, we had a reasonable cross-section of instructions for some of the most popular routers and operating systems. We knew, of course, that there are many, many different devices and scenarios, and we’d have to keep updating our instructions to match the real world.

Our customers couldn’t wait for us (good!). My thanks for these instructions go to individual customers.

We’re adding more ourselves, of course, like Windows 98.

I’m not ashamed to continue asking for help, whether corrections or new screenshots and instructions. We’re quite happy to take raw materials and clean them up (add our orange highlights, spell-check, etc.) to help get the word out to others who might have the same equipment or situation.

Email us your instructions and screenshots: contact at opendns dot com. All the credit will be yours!

Additional information about static IP addresses

We’re learning, to our dismay, that some routers will only let their owners set DNS servers if the owner has a static IP address. Most folks connecting from home (i.e., those who would use the router instructions) have a dynamic IP address.

One example, which was confirmed today to a customer by Motorola customer support is the Motorola WR850 wireless broadband router. Both models, the GP and G, only allow DNS settings to be changed for static IP addresses (PDF manual). Frustrating, but good to know. Earlier, we learned that the Linksys WRT54GC Compact Wireless-G Broadband Router (PDF manual available via this page) has the same limitations.

Fortunately, most people can simply use the operating system instructions, and the settings “closest to the customer” are the dominant ones, corporate networks excluded.

All of this information will make its way into the Get Started pages as we learn more.

OpenDNS out loud: two audio clips

by John Roberts on Jul 31st, 2006

For the audio-inclined, I wanted to share with you two recent clips about OpenDNS.

The first is an interview of David Ulevitch by Mark Howson of The Mac Nurse, conducted via Skype on July 20. The interview runs a bit over 14 minutes. Go listen for yourself (link is to web page, not file). Mark put together an interesting slideshow on top of the audio interview.

The second item for your listening pleasure comes courtesy of David Redekop, one of the founders of Nerds on Site. David and his colleagues join host Ryan Spence every Tuesday to talk about technology on Ask the Experts, on Newstalk 1290 CJBK, in London, Ontario, Canada. This past Tuesday, July 25, Redekop told Spence (and his audience) about OpenDNS.

Listen to the MP3 (6 minutes, 53 seconds; 1.6MB). Redekop explains DNS, explains phishing (and how DNS can help…more on this soon), and explains OpenDNS. I’m pleased to hear that he’s been using OpenDNS since he heard about it, and considers it for his clients.

I would clear up one point from the Ask the Experts segment. The search results page you see if

  1. OpenDNS cannot resolve the entered domain
  2. OpenDNS cannot fix a typo

has both organic (unpaid) search results and clearly labelled advertisements. Redekop says he think that OpenDNS is a service worth using even if all the results are ads on that page (thanks!), but I wanted to clear that up all the same.

Note: In describing OpenDNS, Redekop throws out what he calls “the old phrase”: “There’s majesty in simplicity and simplicity in majesty.” I didn’t recognize the phrase, but a bit of poking around leads us to Alexander Pope, the English poet.

There is a certain majesty in simplicity which is far above all the quaintness of wit.

Learn something new every day.

In his June post Why I Started OpenDNS, OpenDNS founder and CEO David Ulevitch explained how running EveryDNS taught him a lot.

Spammers, Phishers, Botmasters and other Internet Bad Guys use DNS as a vector for running their attacks and schemes to send spam, spread malware and operate phishing sites.

On Friday, July 29, Shadowserver, a public group that tracks and tries to get rid of Botnets (and other bad actors) recognized EveryDNS and David in its inaugural Shadowserver Hall of Fame. Here’s the write-up:

EveryDNS (http://www.everydns.net/) David U. and the EveryDNS team has shut down many botnets. Botnet operators who choose to run domain names provided through EveryDNS have found their net is shut down in quick order. Every abuse email is followed up on quickly and David regularly looks at botnet data provided by Shadowserver Foundation and other agencies to proactively remove abusing botnets before we can send out an abuse report! EveryDNS is responsible for the takedown of a 250k drone botnet last year!

EveryDNS is a separate company from OpenDNS, and focused on a different part of DNS (domain management), but David’s five years at EveryDNS play a large role in the intelligence we’re applying at OpenDNS. We’ve spent a lot of time and attention in talking about phishing, but OpenDNS has plans to contribute in the fight against Botnets, too. Stay tuned.

I know this isn’t the baseball (U.S.) Hall of Fame, which inducted its 2006 class yesterday, but congrats to David and the EveryDNS team, and the other inductees.

Catching up on stats processing (and more)

by David Ulevitch on Jul 27th, 2006

If any of you look at our stats page as often as we do you might have noticed that the weekly graph was a bit wonky today and that we (temporarily) dropped the daily graph. I put a note up on the stats page explaining it but I’m putting a note up here for posterity.

Basically, in order to keep DNS as reliable and awesome as possible we process all of our DNS stats on other machines, out of the DNS traffic’s line-of-fire to you. The machines we use right now to do stats needed some more RAM and hard drives so we paused the stats processing, had some lunch, added some disks and RAM, and then went home. Sometime this morning we decided to start up stats processing again and now it’s nearly all caught up. So there ya have it, the stats were kinda wonky, but our DNS service was hummin’ along like the well oiled machine it should be and is.

As for future changes to the stats page, I have a lot of ideas in my head but I want to know what you want. What kinds of stats are important to you? I want to be sure what’s important to me isn’t just important to me.

On on,
David Ulevitch

Update: I just got teased by some of the guys here for ’signing’ a blog post. Well now there’s a smiley too. :-)

Debian Administrator? Come work for OpenDNS!

by David Ulevitch on Jul 26th, 2006

Update: The position has been filled! Thanks for sending in all the resumes. Good to know lots of folks love Debian as much as we do.

Think you’re elite? Come work with some multi-talented and brilliant folks as our new Systems Administrator.

We’re looking for a really strong Debian Administrator. (in San Francisco)

I put up a post on craigslist.org today with a specific job description but I wanted to get the word out to our users who might be a good fit or know someone who is.

We run a very cool globally distributed network that’s built on Debian Linux so the person we’re looking for should have experience rolling their own packages, running their own apt repositories in addition to being a straight-up unix command-line ninja. Experience with FreeBSD and some networking understanding really helps in this job, too.

You might be wondering why we don’t have one right now and the reason is that I (yeah, a CEO with kung-fu like ops chops), along with some of the developers, all have seasoned skills in the systems and networking area. But that’s going to change when we hire you, it’s time to hand over the reins to someone dedicated to operations full time.

Sometimes people in this kind of position worry that if they do such a good job they’ll be fired because nothing ever goes wrong and it looks like they don’t do anything. That won’t happen here, we all know what it takes to be a really good operations leader. :-)

If you’re interested in this position, just send us all a note at team (at) opendns (dot) com
