T5700 SlimNAS Server: Now With 512 MB Memory

Well it took a couple of tries but I finally got my little SlimNAS server running with 512 MB of memory. I first tried a 1 GB stick of DDR-333 (PC2700), but the T5700 BIOS doesn’t deal with memory greater than 512 MB.

I next tried a 512 MB stick of DDR DDR-333 (PC2700) but that didn’t work either. The little T5700 simply didn’t boot. It never got past the BIOS splash screen.

Then Fedex delivered a 512 MB stick of DDR-266 (PC-2100) that I had mail ordered from www.zipzoomfly.com. That finally worked. So here’s the proof.

Ramble: New Keyboards Making Me Look Bad

I’m kinda picky about PC keyboards. My employer makes a line of TV graphics equipment and has historically bought keyboards from Cherry, a major German manufacturer. I have always liked their feel.

Some time ago they switched to a keyboard that is being custom made for us. Our gear needs a pile of custom keys dedicated to specific functions. So we always need to have keyboards customized.

Customer Owned Fiber

Timothy B. Lee over at Ars technica has an excellent piece on a pilot project going on in Ottawa, Ontario. A neighborhood is getting fiber installed to their homes at their own expense. Once that’s in place any ISP that wants to sell into that area will simply access a central facility to link to the homes in question. The homeowner owns the famously troublesome last mile. It completely bypasses the ILEC and CableCo.

My reactions to this are many. I certainly hope that the project is successful. Ottawa, while unbearably cold in winter, is a serious high-tech town at heart. I wish someone were that adventurous in the US.

With installation costs per home in the $1000 to $2700 range I don’t mind telling you that I’d jump on this in a heartbeat. It’d be like getting FiOS, but owning the last hop yourself.

In the US I doubt our backward thinking ILECs and CableCos will even notice. I see nothing that suggests they are interested in new ways of approaching the market, even if it could leapfrog them into new opportunities. All they want to do is protect their monopoly positions and find new ways to charge ever more for the same old level of service.

No, this kind of NewThink takes a fresh perspective. Let me state unequivocally, if you build it I will pay.

Traffic Shaping For VOIP With m0n0wall

My screencast guide to traffic shaping for VOIP using m0n0wall has been posted on the m0n0wall web site.

However, Manuel Kasper (m0n0wall project lead) had some interesting ideas on how to revise and perhaps simplify my approach. What he describes departs from the approach underlying the present implementation of the Magic Shaper in m0n0wall. Use of the Magic Shaper is the basis of the existing screencast.

Updated to provide a YouTube version in the post and ftp downloadable high quality version.

Updated Home-Office Network Diagram

I puzzles me how to see how many people find the diagram of my home/office network interesting. Yet it consistently gets a lot of traffic, so here’s an update to the original one I posted in March.

m0n0wall Traffic Shaping For VOIP Screencast

After several months of thinking about it I finally got around to recording a screencast tutorial about setting up the traffic shaping feature in m0n0wall to accommodate VOIP traffic. Phillip Cooper’s series of screencasts were the inspiration for this. In going though his work (thank you!) it occurred to me that  documenting the settings that allow my VOIP systems might be useful to others.

I have a new (ish) Comcast cable modem service here in my office, which gave me a testbed to setup another router and go through the setup process from scratch.

The finished screencast is not online yet. I’ve passed it to the m0n0wall project leads for comment & revision before making it public. It should be available in the next few days.
