Since I first encountered Vyatta two years ago, they have grown beyond merely being an open source software router. These days, Vyatta is calling itself an “open-source networking” company, and their router is now a router/firewall/VPN.

Dave Roberts, Vyatta’s VP of Strategy, spoke on a panel session called “Open source networking: An insanely smart idea?” at Interop Las Vegas 2008. I asked Dave whether open source networking was making any progress against the common arguments against its use in businesses, such as companies wanting the assurance of “one (vendor’s) throat to choke” should they have problems with the technology. Dave says that issue is “exactly the problem Vyatta was created to solve,” and said that they wanted to bring together all the disparate open source parts to become the “Red Hat of the networking industry.”

In this video, Dave talks a little bit about where Vyatta is now, some of the company’s recent price/performance successes, and new features they’re offering.

SHARKFEST: Open source network analysis fans churn up the waters with the Father of the Internet and Mother of Invention

Just when you thought it was safe to go into the NOC….da, dum….da, dum….that’s when SHARKFEST sneaks up on you.

Actually, SHARKFEST is an event about protocol analysis, an activity we at SearchNetworking highly recommend to make you safer, in networking terms, at least. The use of protocol and network analyzers can not only root out problems in network performance but also discover all kinds of nasty security holes and potential vulnerabilities in your network. The conference is put on for developers and users of the open source network analyzer Wireshark (formerly known as Ethereal). If you live or plan to be in the Mountain View, Calif., area this week, SHARKFEST will be held at Foothill College today through April 2.

What’s really exciting for the Wireshark folks is that the keynote speaker on Tuesday is Dr. Vinton Cerf, a man regarded by many as one of the Fathers of the Internet. Cerf now serves as vice president and chief Internet evangelist for Google (but, hey, we all have to eat, right?), chairman of the board of ICANN and honorary chairman of the IPv6 Forum. According to the SHARKFEST agenda, Vint will be talking about “non-discriminatory network service.”

In a press release, Gerald Combs, Wireshark creator and director of open source projects at CACE Technologies, co-sponsor of the event, said, “Dr. Cerf’s presence at SHARKFEST ‘08 is an amazing testament to the importance of the open source movement and the Wireshark project.” I have to agree. Although Vint’s role at Google is “evangelist,” you don’t see him speaking often to IT audiences, so his presence is quite a coup. I hope the attendees think of some tough questions to challenge him.

So SHARKFEST has a lot going for it. 1.) It has a very cool name (despite the hyper-capitalization). 2.) It has the Father of the Internet. 3.) It has my all-time favorite IT speaker in the whole world: Laura Chappell. She’ll be giving sessions on trace file analysis, TCP/IP resolution processes, network forensics, cool security tools, and case studies about solving network performace issues with WireShark.

Laura is the founder of Wireshark University and the Protocol Analysis Institute. She has trained thousands of network and security administrators, saved hundreds of companies from ruin and embarrassment, and worked extensively with government agencies to safeguard networks and improve security measures.

If you have not seen Laura Chappell in action, you do not know what you’re missing. Not only is she funny and energetic and a riveting speaker, but she will show you things you can find out about your network that you never thought were possible. All with very simple, mostly free, tools. She’s so neat that Disney has optioned a script tentatively called “Mother of Invention” based on her life.

Open source networking hums along, quietly

Open source has been buzzing lately: Gartner identified it as one of the top 10 trends for 2008, and last week Microsoft announced it was publishing 30,000 pages of documentation for Windows Server 2008 and Windows Vista and launching an “Interoperability Initiative.” Google is pushing open applications and development of the new Android operating system, while Verizon claims to be opening its network.

In the networking industry, however, while open source adoption seems to be growing at a good clip, I don’t see much hoopla about it. So I’ll forgive you if you missed Shamus McGillicuddy’s article about the launch of ZipForge, a new website Alterpoint developed to support its ZipTie open source network configuration product. The ZipForge site provides a place where AlterPoint vendor partners can post interoperable ZipTie components that developers and users can download, review, and contribute to.

snortIt would be great to see users take advantage of this repository to consolidate other networking-specific software tools, much like a true SourceForge (from which the new site partly takes its name) for networking pros. According to the article, networking has experienced less of an upsurge in open source because the technology itself is so reliant on hardware. While that may be true in a basic sense, software is becoming far more important and familiar. There are already several open source programs that networking folks use regularly, and that list is bound to expand.

Network engineers have long used open source software to run routers, VPNs and VLANs on run-of-the mill servers. Snort, OpenNMS, Nagios and Nessus are staples in networks big and small. And the popularity of Asterisk, the open source IP telephony platform, continues to grow in leaps and bounds.asterisk

Open source is definitely a part of the network, but I think that’s how most networking pros view it — as just a part of the network. They choose it because it works well, it interoperates, or it’s cheap, and they don’t get too caught up in the idealism and spreading the word about the benefits of open source. Also, most networking pros wear so many hats that they can’t spend a lot of time thinking about one system or product. They are even less likely to use that time evangelizing or flaming posts over at Slashdot.

I recall a network administrator I met a while back at a trade show. He had installed a few Vyatta routers, and he thought they were fantastic. But he was also in the throes of rolling out Avaya IP telephony to multiple locations and installing a new supply chain automation system. So while he was happy with his open source routers, they probably weren’t the first thing on his mind. The buzz about open source in the network is there, but sometimes you have to listen hard to hear it.

Bizarro VoIP: Is it evil? Do you care?



Posted by: Amy Kucharik

Recently, Tom Keating at TMC wrote in his blog about Digium acquiring Switchvox, a proprietary Asterisk-based VoIP solution. Keating had interviewed Asterisk inventor and Digium CTO, Mark Spencer, who explained that one of the goals of that acquisition was to assimilate some of the proprietary technologies from Switchvox back into open source. Keating remarked:

I recalled Mark Spencer’s IT Expo keynote where he espoused the benefits of truly 100% open source solutions and how this contrasted sharply with some of Digium’s competitors such as Fonality. Again, Mark called hybrid-open/proprietary solutions “evil.” I couldn’t help but think of Digium vs. Fonality as Superman vs. Bizarro. Who is Bizarro and who is Superman I leave for you to decide…

One month ago, at TMC’s Internet Telephony Conference & Expo in Los Angeles, I had the pleasure of meeting Mark Spencer. Unfortunately, I had missed the relevant part of Mark’s keynote, which (fortunately) Greg Galitzine summed up nicely in his blog:

[Spencer] mentioned the evolution in the open source world, where things have gone from a simple “good versus evil” debate (open source vs. proprietary) to a complicated new world where we find open source (good) fake open source (bad) proprietary open source (evil), and even proprietary hybrid hosted (really evil).

Naturally, being drawn to all things evil, the next day at the conference I met with the dark lord of the open source PBX world, Chris Lyman. OK, Chris isn’t actually evil (to my knowledge) — he’s the CEO of Fonality. Fonality, one of the “proprietary hybrid hosted” companies makes low-cost phone systems — according to Lyman, their Trixbox platform is the first and biggest built on top of Asterisk code.

According to Fonality’s website, being a hybrid-hosted phone system means that the free software is first downloaded by a business and installed on a local computer and local IP phones. After this step, the local computer connects to the Fonality network where server health, call quality and usage are constantly monitored. The hybrid-hosted nature of trixbox Pro also securely extends the phone system outside the corporate firewall, so an employee’s extension can follow them when they work from home, remotely on a laptop, or even on a mobile phone. (Thanks to Alicia diVittorio for tracking down the definition.)

Sounds like a pretty good arrangement, especially for SMBs who may not have the resources on staff to manage a premise-based solution. In a tip on SearchVoIP.com, Yankee Group senior vice president Zeus Kerravala advised companies:

Even if you’re a predominantly do-it-yourself IT organization, consider a hybrid environment where the hosted services are used for some of the smaller branches and telecommuters. This will probably scale much more easily for you as you move more locations over to VoIP.

What I’m trying to figure out here is why the proprietary hybrid hosted model is “really evil,” and I can’t seem to track down Mark Spencer to comment. (Hey Mark, if this is a secret alter ego thing, I’d be just as happy to talk with Superman!) Personally, I’ve been a proponent of open source for some time now. I understand the benefits of encouraging innovation and avoiding vendor lock-in and lowering per-port charges. So, is Fonality locking in their customers? Are they corrupting open source ideals? Will they stifle innovation? Will mixing open source and proprietary code cause an explosive reaction, like encasing Kryptonian crystal in green kryptonite?

And, despite all this, “Most of the people buying the phone systems in the SMB space don’t even care if it’s open source,” Chad Agate, Co-Founder & CEO of NeoPhonetics, a Digium partner, said during a conference session on “Selecting an open source VoIP solution for the SMB.”

When I asked Lyman about the whole “very evil” issue, he pointed out that Digium has their own tricky issues and aren’t as pure as the driven snow when it comes to open source and their “Digium Waiver” (Read xrobau’s blog on Fonality and the GPL for more about that.)

“This shouldn’t be a war of the Davids; the Davids should join forces and take on Goliath, which is Cisco,” Lyman said. “Fonality and Digium don’t equal one half of one percent of U.S. PBX market share.”

Hmmm…
