Workshop, Linux based consumer routers and WiFi, dd-wrt and OpenWRT

2008-12-11 19:30
2008-12-11 21:00

We will be having this event on two dates December the 11th and December the 18th.

Workshops on putting open source firmware on many of the consumer routers.

The LinkSys WRT-54GL and previous versions of that router were mainstream for years... but G radio is pretty weak by today's standard; The new N routers are not just about faster signal, but the real benefit is often the better antenna MIMO signal designs.

With many routers, two or more can act as wireless repeaters (WDS mode) allowing you to reach areas with wired or wireless. It is also possible to connect two routers back to back with Ethernet cable and share out an existing WiFi connection with a new name and signal.

I will bring two Linksys WRT-310N routers with dd-wrt loaded and discuss the loading process, features, and . This is a well supported Linux router available at Buy.com, Newegg, Amazon and so forth for around $85 (also goes on sale at times for lower). This is a Broadcom based router with 32MB of RAM for running Linux - allows you a lot of flexibility in what services it can perform for your network. It is a little more expensive model given it is also a gigabit switch for the cabled side of the network.

We will also show a Atheros based Netgear WNR2000 802.11n router running a customized version of OpenWRT. Information on OpenWRT is here

Presentations can be as short at 15 minutes or as long as 90 minutes. We have provisions for a VGA display hookup if you wish to bring a laptop for your presentation. ANYONE is welcome, you do not have to have presentation experience!

Please contact us on the mailing list, or reply to this topic if you are interest. we like to schedule presentations at least one week in advance. Thank you.

Installing Linux on low memory hardware.

Many distros do not install because of low memory on some old computers. I have a laptop for which, sans swap file, Ubuntu won't even boot and yet I have installed Open SuSE on it.

Never mind what the 'systems requirements' say. Many well known distros like ubuntu, opensuse and fedora can be made to install on low memory computers if you install a swap file first.

How to do it. Plan your basic partitioning. Download and burn the GParted Live CD. This Software can also be made to boot from a usb stick.

Boot, delete or move existing partitions and install a /boot and swap partition in the low numbered cylinders. (Old hardware is often subject to BIOS Cylinder limits. The /boot partition is used to insure that your kernel image and initrd are in partitons that satisfy these limits.)

With the Swap file in place, you can almost install your Distro as you would normally.

If the Distro installation procedure asks for permission to use your swap file, say "yes".

Do not let the distro installation procedure automaticly repartition your hard drive, because it may attempt to move the swap file. It won't work to try to move a swap file that is in use.

Specify "manual disk partitioning". This has different names for different distros.

During repartitioning, you can do anything you want except move or delete the swap file. (If you need to move the swap file, you will have to abort the installation, and go back to the beginning and repartition with the GParted LiveCD.)

Once the disk repartitioning phase is complete, the rest of the installation usually procedes normally. If you are installing on the typical piece of junk, expect everything to proceed slowly, much more slowly, than you are used to.

There are also other tricks to install Linux on computers without a CD or DVD drive.

The Linux Foundation excludes local Linux activist from local Summit

I am a local Linux activist. I am secretary of a local LINUX Lug, and I have written commentaries on Free Software/Open Source Software history. When I read about the LINUX Foundation Collaboration Summit in the local paper I thought I would like to attend. So, I put on my suit, which I do not wear often and headed off for the Pickle Research Center.

When I reached the summit registration, I talked to Jennifer Cloer. I said that I was secretary of a Local Lug and that I have written on Free software/open source history. I asked to attend as an observer and journalist. She said that journalists were only allowed the previous day and that remaining days were only for Linux Foundation Members. Our local LUG was never notified of the existence of the summit in Austin.

The front page of the Linux Foundataion's Web page says "The Linux Foundation is a non profit consortium dedicated to fostering the growth of Linux". Fostering the growth of Linux is also what Austin Linux Group is supposed to be doing. The event was called the "collaboration summit", but apparently the LINUX foundation did not want to colaborate with any one but themselves.

There was a forum on open source legal issues from which I could have profited. Too bad.

I believe that local LUGS and local LINUX activists have much to contribute to the development of LINUX. I believe that the LINUX FOUNDATION is making a mistake by excluding them.

We are stronger together than separate.
