Wireless Mesh Networks under FreeBSD (video)


Rui Paulo: Wireless Mesh Networks under FreeBSD

AsiaBSDCon 2010 paper session.

Abstract:

With the advent of low cost wireless chipsets, wireless mesh networks became much more attractive for both companies, governments, and the general consumer. Wireless mesh networks are being used extensively since the popularization of the 802.11 wireless technologies, but usually they worked with the help of layer 3 routing technologies.

Since 802.11 didn’t provide any kind of support for wireless mesh networks, in 2004, IEEE created the Task Group s (TGs) to develop a new amendment to 802.11 which would define the operation of a wireless mesh network using existing 802.11 hardware and having a routing protocol work at layer 2. Later, the amendment also included provisions for mesh authentication, encryption, link management, bridging mesh networks with other types of networks, and channel reservation.

This paper will talk about the FreeBSD implementation of 802.11s that’s available in version 8.0 and beyond. This work was sponsored by The FreeBSD Foundation.

Porting HPC Tools to FreeBSD (video)


AsiaBSDCon 2010 paper session.

Abstract:

Since 2001 we have used FreeBSD as a high performance computing (HPC) cluster operating system. In the process we have ported a number of HPC tools including Ganglia, Globus, Open MPI, and Sun Grid Engine. In this talk we will discuss the process of porting these types of applications and issues encountered while maintaining these tools. In addition to generally issues of porting code from one Unix-like operating system to another, there are several type of porting common to many HPC infrastructure codes which we will explore. Beyond porting, we will discuss how the ports collection aids our use of HPC applications and ways we think overall integration could be improved.

Audio presentations: 1 pfSense and 2 BSD for Linux Users

Dru Lavigne has uploaded the audio file of her presentation at SCALE 2010 talk on BSD for Linux Users is now available in mp3 format. Slides are available as PDF

She also mentioned an mp3 of a NYCBUG session on PFSense II, Rocking The Datacenter.

pfSense is a free, open source customized distribution of FreeBSD tailored for use as a firewall and router. In addition to being a powerful, flexible firewalling and routing platform, it includes a long list of related features and a package system allowing further expandability without adding bloat and potential security vulnerabilities to the base distribution.

AsiaBSDCon 2010

AsiaBSDCon 2010 will be held from 11-14 March in Tokyo

AsiaBSDCon is a conference for users and developers on BSD based systems. The next conference will be held in Tokyo, in 11-14 March, 2010. The conference is for anyone developing, deploying and using systems based on FreeBSD, NetBSD, OpenBSD, DragonFlyBSD, Darwin and MacOS X. AsiaBSDCon is a technical conference and aims to collect the best technical papers and presentations available to ensure that the latest developments in our open source community are shared with the widest possible audience.

Report from EuroBSDCon 2009

eurobsdcon2009Nik Clayton, site reliability engineer at Google,  has written up an account of what he’s seen, heard and done at EuroBSDCon 2009.

I’m no stranger to EuroBSDCon. After attending several very successful conferences in the US, three FreeBSD contributors and I decided that Europe needed a BSD conference too. In November 2001 we were proud to host 160 or so delegates in the first European BSD Conference. Over the last couple of years I haven’t been able to keep as up to date with the latest developments in the BSD world, so I was very interested to attendEuroBSDCon 2009, organised in collaboration with the UK Unix User Group.

With the conference split in to several tracks it was impossible to attend every talk, so I decided to focus primarily on those that talked about how BSD systems were helping people solve problems in the real world. Links to all the papers, slides, and in some cases audio from the presentations can be found at conference schedule page.

The first talk I attended was “How FreeBSD Finds Oil,” given by Harrison Grundy. Harrison runs a consultancy company in the US providing clustered computing systems to oil and gas companies.
