Running a Network Server without a Computer

We recently pulled out the Linksys Network Storage Link USB 2.0, aka the NSLU2, affectionately nicknamed the SLUG by enthusiasts. The NSLU2 is actually a Linux-based device, which runs SAMBA, a version of Windows file sharing and has been hacked to run other things.

The NSLU2 is not your only choice for hacking in this manner. You can use the Synology DS101, the Iomega NAS100D, the D-Link DSMG600, or any device that uses the ixp4xxx chipset with attached storage. However, the NSLU2 has the most following, having had an established community for a long time.

There are several options for replacement firmware for the NSLU2. There is Unslung, which allows you to expand the ffunctionality of the NSLU2 without using the original product functionality and compatibility with the original Linksys firmware. However, unlike the stock firmware, Unslung contains support for NTFS(The formatting used for Windows drives), card readers, USB hubs to add extra devices, and other enhancements. Other packages can be installed to a drive hooked into the Slug as it has limited memory and run, for example, a streaming media server.

Alternatives to Unslung include OpenSlug and Debian for the NSLU2, which remove the Linksys functionality in favor of a complete Linux system, and thus are not for the neophyte.

For more information on the various aspects of the NSLU2, visit its unofficial homepage/wiki. We just set one up as a file server at a remote location. It will, as soon as we finish setting up the software, not only backup files from the main server, but allow users at the second site to access local copies of their documents.

Let's Talk about X10 and Insteon

Smarthome, Inc.

You may notice our Smarthome button available on all pages. We have not spent much time talking about them. Smarthome is a computer that specializes in home technology…including surveillance, lighting and appliance control, and so on.

They come to our mind today because we called in an electrician to fix the lighting system we’d failed to succeed in installing ourselves. The system uses X1o-based technology.

X10 is a standard that uses signals sent along the power lines. One can also use radio transmissions to trigger the powerline signals. X10 devices include dimmable lamp modules, appliance modules, outlets, and light switches…as well as a variety of control mechanisms.

One of X10’s problems is that is prone to interference from other devices. However, it remains popular despite this. The most common X10 switches are the inexpensive ones sold by X10 Technology, Radio Shack, and even Smarthome itself. These switches are easy to install, but are prone to failure. They are however a good starting point if you just want to experiment.

For reliability, try Leviton or Smarthome constructed X10 switches. They are a bit more expensive, but come at varying levels of quality…all of which are more reliably. Smarthome itself has been promoting its Insteon line of products. Insteon products are backwards compatible with X10, so you don’t have to rip out your existing wiring, should you have it. But they also send radio signals which are repeated by every Insteon device.

However, setting up Insteon is a bit more expensive than their X10 offerings, and their older X10 only lines are being discounted now…so it is a good time to click the link above and buy.

Thus, we come to the reason why we called an electrician. We have no trouble installing single switches, however,  three-way and four-way switches(where two or more switches control a single light) continue to elude us. That and the fact that whoever wired our home originally did it in an…as the electrician put it…”unconventional way.” We hope to master the skill someday. Fortunately, with the diagnostic assistance of the electrician, everything is working perfectly.

We take a targeted approach to home automation. It is set for certain lights. The lights on our exterior porch are set on a motion sensor that trigger the inside hall lights. In one room, remote switching is used to avoid installing a second switch in the room. When combined with a security system, we could extend this even more.

Give it a look. Feel free to comment with your home automation stories or questions. We may feature them in future posts.

More on Piracy

Last month, the Consumerist asked if the DRM phenomenon drove well-meaning people to piracy. We invite you to review the story of one man who did so despite his best efforts.

We may not be the right people to discuss DRM. We have never purchased music from an online store and we refuse to buy an iPod. But when hearing something like this…

There I sat, a loyal music fan who has shelled out actual money to a business that is supposed to be having financial problems, and the best they can do is tell me to wander the streets of Seattle looking for different internet providers who might allow me to download the music that I have already paid for, music that I have spent the better part of three house trying to listen to, and which is still unusable?

We tend to think we made the right decision. We rip our music from CDs, make plans to, but fail to convert our old cassettes and vinyl to MP3. But we have withdrawn from online music downloads because of the above…it just seems too complicated to us. And iPods…well…we bought a 1GB Sandisk MP3/WMA flash memory player for $19.99 after rebate. We haven’t had any problems with it.

There are people who are willing to deal with the restrictions of music in order to buy through these companies. We salute them. There are also people who find ways around it, and those who pirate. We wish them luck in their endeavors as well.

In good news, the EMI Group will be selling premium DRM free music via Itunes in May, excepting Beatles tunes. Higher-quality music files, which will play on any computer and any digital-audio player, will not replace the copy-protected EMI music currently sold through iTunes. They will still offer the standard 99-cent iTunes downloads. DRM-free will be 30 cents more. Existing customers will be able to upgrade. Full albums will costs the same, DRM or non-DRM.

Tests by EMI indicated the higher-quality, DRM-free songs outsold the DRM ones ten to one. Steve Jobs of Apple has advocated the elimination of DRM in the past, and this seems to indicate that the recording companies are reconsidering the current situation.

The PowerSquid

The Powersquid is an outlet multiplier…an alternative to the conventional power strip. Conventional powerstrips often find their outlets blocked by oversized cables and transformers. The Powersquid, which is available in models with and without surge suppression. Phillips Electronics also makes a version of the product found in stores.

Check it out. We have one and it avoids us having to use outlet extenders and other tricks to fill a power strip.

Why Can't We Be More Like Australia?

How often do you hear that line?

Australian news reported that Federal Environment Minister Malcolm Turnbull announced on February 20th that standard incandescent bulbs would be phased out within three years. Details of the plan, including costs, will be made available later. It is felt the change could cut greenhouse gases by 800,000 tons a year by 2012.

In Canada, Ontario, Nova Scotia and New Brunswick considered banning the incandescent light bulb, following Australia’s lead. After all, one part of the former British Empire can’t be more progressive than another.

And the United States doesn’t want to think Canada could be more progressive than it…so CBS news reports, California may also ban the light bulbs. Most light bulb manufacturers support the phasing out of the bulbs, but at their pace, feeling that it is unnecessary to ban older bulbs to force the issue.

We ourselves are fond of the bulbs, although we do have a few halogens in certain places for which there are not yet better replacements. We’ve been experimenting with dimmable fluorescents of various brands and the technology there continues to improve.

For those of you following, our new favorite place to buy bulbs is now 1000bulbs.com, which may have had our dimmable bulbs backordered, but provided excellent customer service and reasonable pricing on all our needs.

More on DRM and Illegal File Sharing

  • Bruce Schneier has an article on DRM in Windows Vista. Not only does Vista implement extensive DRM, but it also continuously spends CPU time monitoring itself, trying to figure out if you’re doing something that it thinks you shouldn’t. If it does, it limits functionality and in extreme cases restarts just the video subsystem. Not exactly a friendly feature.
  • The RIAA sued a woman for allegedly sharing copyrighted material. She had her case dismissed and was awarded attorney’s fees in excess of $50,000. The RIAA, however, filed an appeal, to reconsider the decision to make them pay. They want the judge to rule that an owner of an ISP account is responsible for all activity on that account. Such a ruling could make individuals running open hotspots and/or offering public wireless access liable. The RIAA has tried before to establish such a precedent.
  • The Consumerist reports that the RIAA has sent letters to 400 students at 13 universities encouraging them to confess to illegal file sharing and pay a “settlement” at P2PLawsuits.com. The RIAA has limited evidence these students are doing something illegal. They have a link to a PDF of the offending document here. If they don’t pay, the RIAA will subpoena the names of the students they say they’ve caught from the schools’ IT departments.

Verizon Suing Vonage for Infringement

The Asbury Park Press reports that Verizon is suing Vonage for patent-infringement, alleging that Vonage has “appropriated the results of years of research conducted by Verizon and its predecessors.” The patents Verizon claims have been violated cover the interfaces between the old phone system and the more modern computer system mimicking it and are essential for providing VoIP phone services that mimic traditional phone service.

Because the patent claims are so broad… Vonage would never be able to operate, nor would any other VoIP service, most likely. Vonage considers it likely that the courts will invalidate the patents.

Encrypting Your Web Browsing Session

Lifehacker has a great feature on how to encrypt your web browsing with an SSH Socks Proxy.

  1. You’ll need an SSH server. If you don’t have access or can’t get access through a web host, many of which allow this access, you can always run your own.
  2. You’ll also need a client. The most popular one for Windows computer is Putty. It is simple to use.
  3. Set up your SSH client to establish a tunnel between a local port and a port on the server.
  4. Set up your Internet browser to use a Socks proxy.

Now, that seems a bit hard for some people. There are alternatives.

  • Tor – Tor is a toolset for those who want to anonymize their internet usage.
  • Routers – Various routers can run SSH and even a SOCKS proxy. Most of these are Linux-based routers running custom firmware. More information

MPAA Violates a Licensing Agreement

The Motion Picture Association of America, best known for encouraging people to help stop movie thieves, and going after those they consider responsible for such thefts, was using a piece of software called Forest Blog to run its blogs, according to one blog.

Forest Blog, written by 29 year old developer Patrick Robin, is distributed under a Linkware license, which means that anyone who uses it must link back to his site or purchase a license. So essentially, the MPAA is so upset about piracy that they pirated software to run their blog. It is not the first time they have been guilty of such hypocritical behavior.

Removing Your Paper Trail

Many of us spend time organizing their computers…Courtesy of O’Reilly’s Onlamp.com, we present this simple article, with simple advice on ridding yourself of paper, slowly. Here’s our version.

  1. Document Control System. The simplest one is, of course, a simple folder structure. Using directories requires no special software. That also means it has no ability to assist or monitor your organization. The author of the article suggests Perforce, which is a commercial product that offers a free version. We recommend the alternative, the free open-source Subversion, based on CVS, which is used by programmers. PC Magazine had a good basic article on it you can find here.
  2. A Scanner – To get your documents into the computer and out of your hands. One with a reliable ADF(Automatic Document Feeder), will allow you to work much faster in ridding yourself of documents than otherwise.
  3. Organize your files – You have to be able to find your documents by creating a hierarchy…a series of directories and subdirectories that allow you to quickly navigate to your files.
  4. Integrate your scanned documents with ones created by computer…they are all forms of information. And one useful thing about computers…if something fits in more than one category, you can link your file to both locations.

For a while, we tried Paperport, which came with one of our first scanners. We still have hundreds of files in the proprietary Paperport format we plan to slowly converting to PDF files for the straight documents and JPEG and GIF files for the higher resolution imagery. More on our plans to come….
