Conoce alguien de un ATA inalámbrico ?

Anyone know of a wireless ATA ? Q / I have a project to interface an ATA to "standard" security alarm panels. I have already got quite close with an Sipura SPA3000 ATA, however, a potential marketing company want a "plug and play" solution where all the customer has to do is unplug the RJ11 from their existing alarm monitoring, connect it into an ATA, power up the ATA and that's it. They do not want the customer to start running ethernet cables through their homes to a router that is in the lounge one week and a bedroom the next. The only wireless ATA I have managed to find so far is from a company called SMC. It has custom tone generation (which I require), but it does not have remote provisioning - which would be nice. Anyone know of another wireless ATA ? **Please note I am not sending DTMF over a VoIP channel. I use IP dialing to send data via UDP. Steve N. A/ Steve: You could connect your SPA3000 to a WBP54G and it (SPA3000) will be a wireless ATA. Yo can buy it from amazon.com for about US$38. Juan C. Product Features

Apple Introduces Innovative Cellphone By JOHN MARKOFF Published: January 10, 2007 SAN FRANCISCO, Jan. 9 — With characteristic showmanship, Steven P. Jobs introduced Apple's long-awaited entry into the cellphone world Tuesday, pronouncing it an achievement on a par with the Macintosh and the iPod. Apple Apple iPhone.   The creation, the iPhone, priced at $499 or $599, will not be for everyone. It will be available with a single carrier, Cingular Wireless, at midyear. Its essential functions — music player, camera, Web browser and e-mail tool as well as phone — have become commonplace in hand-held devices. But it was the ability to fuse those elements with a raft of innovations and Apple's distinctive design sense that had the crowd here buzzing. Apple's goal, Mr. Jobs said, was to translate the Macintosh computer's ease of operation into the phone realm. "We want to make it so easy to use that everyone can use it," he said. And he was clearly betting on translating Apple's success with the iPod music player to a hot category of multifunction devices. Underscoring the transformation of a quirky computer maker into the dominant force in digital music, and signaling his ambitions to extend that reach, Mr. Jobs also announced that Apple was dropping "computer" from its name and would henceforth be known as Apple Inc. Investors took quickly to the pitch, sending Apple's stock price up to a record close, while shares of established cellphone makers slumped. Still, the phone is a gamble on a new business for Apple. And even with its success with the iPod and a reborn line of computers, it has not been immune to marketplace failures, like the Macintosh Cube introduced in 2000. But in his two-hour presentation before an audience of reporters, analysts and Apple employees at the Macworld Expo trade show, the parallel he repeatedly drew was between the new phone and the Macintosh personal computer, which had a vast impact on the computer industry when it arrived in 1984. Noting that there are occasionally new products that change everything, Mr. Jobs said, "Apple has been able to introduce a few of these into the world." He said Apple had set the goal of taking 1 percent of the world market for cellphones by the end of 2008. That may seem small, but with a billion handsets sold last year worldwide, that would mean 10 million iPhones — a healthy supplement to the 39 million iPods that Apple sold last year. "Steve can make the internal combustion engine appear to be something new and cool," said Reed E. Hundt, the former commissioner of the Federal Communications Commission. "He will provide a certain magic even to the 30-year-old cellphone." Mr. Jobs's product tour de force was even more remarkable for its timing, as questions continue to be raised over the company's stock options practices and his role in them. "The truth of the matter is everything is fine," he said during an interview after his presentation. "We've shared it all with the S.E.C." He acknowledged the controversy over the timing of some of Apple's stock option grants, which Apple appears to have fanned recently with a disclosure to the Securities and Exchange Commission that contained a circumspect description of his role in the options award process. "It's raised questions," he said, "but some of the journalism has been so off the mark. But I know the truth. It's painful to read some of this stuff, but I know it's kind of ridiculous and will pass." If he is in any trouble, Mr. Jobs showed no signs of it either on stage, where he was treated with great warmth by his audience of 4,000, or in an interview afterward in which he showed obvious delight in highlighting subtle industrial design features. Mr. Jobs showed a series of applications including e-mail, advanced voice mail, photo collections and visually appealing Web searching. He promoted the fact that the new iPhone is powered by the same core OS X operating system that the Macintosh computer is based on, offering power-management features and advanced graphics abilities. The user interface relies heavily on a high-resolution touch screen that makes it possible to use a finger to control the phone. It has features that are still more subtle, including sensors that track light and movement and proximity, to prompt the phone to control screen brightness and physical orientation and other aspects of its operation. For example, when the phone is placed next to the user's face, the keyboard is automatically turned off. Apple chose the name iPhone even though Cisco Systems, the network and consumer wireless company, has recently introduced a Wi-Fi-based phone with the same name. Mr. Jobs had been negotiating with Cisco executives over the trademark in recent days. The $499 version of the device will have four gigabytes of storage, and the $599 version will offer twice that. "At $499 and $599, it's a pretty expensive deal," said Rob Glaser, chief executive of Real Networks, whose online music store is a rival of Apple's iTunes Store. "Steve is more focused on not cannibalizing iPod sales than on driving volume of phones. Those are not high-volume prices." Mr. Jobs defended the higher price of the new phone in a market where prices of so-called smartphones — those combining voice calling with Internet functions — are rapidly plunging to $200 and below. He contrasted the iPhone, which has only one mechanical button on its surface, with the BlackBerry and smartphones from Motorola and Palm. Rather than what he called "small plastic keyboards," the iPhone will have a display that becomes both the keyboard and control panel, morphing to suit the current application. "After today I don't think anyone is going to look at these phones in the same way," he said. Apple's relationship with Cingular began two years ago when Mr. Jobs phoned Stanley T. Sigman, Cingular's chief executive, and proposed that they speak about a relationship. The two had an initial meeting in February 2005 in a New York hotel. Apple spoke with other carriers before committing itself to its exclusive link with Cingular, Mr. Jobs said, but he would not give details. In addition to the Apple relationship with Cingular, which Mr. Jobs said was forged without offering the wireless carrier even a peek at an early prototype, the iPhone will offer special applications from both Google and Yahoo. Users will be able to use both services' search and e-mail services as well as a custom version of Google Maps. Eric E. Schmidt, who is chief executive of Google as well as a member of Apple's board, and Jerry Yang, co-founder of Yahoo, came on stage to endorse the new hand-held. "I'm not a board member of Apple, but I would like one of these, too," Mr. Yang said. Regis McKenna, the veteran public relations specialist and corporate strategist who tutored Mr. Jobs in the art of high-tech marketing beginning in the late 1970s, said: "This compares favorably with the launch of the Macintosh. The price is high, but it will come down." Despite the widespread comment and enthusiasm that the phone generated, there were also many questions about its design and about Apple's strategy. Some analysts and industry executives noted that the Apple designers had shunned Cingular's higher-speed digital cellular network. Mr. Jobs said later models would have additional networking standards. Others questioned whether the device would be as versatile as other smartphones if it was not truly open — that is, able to accommodate many programs from third parties, as personal computers are. Mr. Jobs would not say how open the phone would be to other developers, but added: "I don't want people to think of this as a computer. I think of it as reinventing the phone." He also said he was anxious to help protect the Cingular network from the kind of viruses and worms that bedevil the PC world today. The phones will go on sale in June through Apple and Cingular (online, by phone and in stores). Mr. Jobs said the phone was being announced ahead of its availability to head off disclosure that might have resulted in the course of Federal Communications Commission licensing. Although it will be a half-year before it is possible to know whether Mr. Jobs has another hit product, there was no shortage of enthusiasm based on the first glimpse today. "It's like they read our minds," said David Myers, executive chef at Sona restaurant in Los Angeles and chief executive of the Food Arts Group, where the employees currently use the Treo smartphone from Palm. "This is the next step in not accepting poor design any longer." Before he introduced the phone, Mr. Jobs said Apple TV, the digital video system that he announced as iTV last year, would be available for $299 in February. The device will store up to 50 hours of video and permit wireless streaming of content from a computer to a television. Laurie J.

MacWorld 2007 San Francisco Presentación del iphone Apple

New Mobile Phone Signals Apple's Ambition By JOHN MARKOFF Published: January 9, 2007 SAN FRANCISCO, Jan. 9 — Steven P. Jobs introduced an Apple wireless phone today that he said would lead to a new synthesis of communications, video, music and computing. Kimberly White/Reuters Steve Jobs, Apple's chief executive, said the iPhone would "reinvent" the telecommunications sector. Paul Sakuma/Associated Press Steve Jobs introduced AppleTV at the MacWorld Conference & Expo in San Francisco today.   In an exclusive partnership with Cingular, the nation's largest cellular phone carrier, Mr. Jobs brought his legendary product design sense to bear on one of the world's most ubiquitous products. He said Apple had set the goal of taking 1 percent of the world market for cell phones, or 10 million phones per year, by the end of 2008. Underscoring the transformation of a quirky computer maker that during the past half decade has come to dominate the world of digital music, and signaling his ambition to become a force in new markets, Mr. Jobs announced that the Apple was dropping the "computer" from its name and would henceforth become Apple Inc. Repeatedly during his two-hour presentation before an audience of journalists, analysts, Apple employees and customers, Mr. Jobs drew parallels between the Macintosh personal computer, which had a vast impact on the computer industry when it was introduced in 1984, and the new phone. Noting that there are occasionally new products that change everything, Mr. Jobs noted, "Apple has been able to introduce a few of these into the world." Apple's stock price rose more than 7 percent after the announcement, climbing over $92. Shares of two companies that make competing smart wireless devices, Palm Inc. and Research in Motion, fell more than 5 percent. Touting the fact that the new iPhone is powered by the same core OS X operating system that runs Macintosh computers, Mr. Jobs showed a series of applications including e-mail, advanced voice mail, photo collections and visually appealing Web searching all on a device that will be priced beginning at $499. That model will have four gigabytes of storage, and an eight-gigabyte model will be available for $599. The iPhone will offer five hours of operating time and 16 hours of audio playback, Mr. Jobs said. The phone will be compatible with Cingular's digital EDGE data network as well as Wi-Fi and Bluetooth networks. Mr. Jobs defended the higher price of the new phone in a market where smartphone prices are rapidly plunging to $200 and below. He compared the iPhone, which has only one mechanical button on its surface, to smartphones from Motorola, Research In Motion and Palm.

Regis McKenna, the veteran public relations specialist and corporate strategist who originally tutored Mr. Jobs in the art of high-tech marketing beginning in the late 1970s, said: "This compares favorably with the launch of the Macintosh. The price is high, but it will come down." The new phone will not go on sale at Apple and Cingular stores in the United States until June of this year, Mr. Jobs said, noting that he had chosen to avoid early public disclosure on a Federal Communications Commission Web site. The iPhone will be introduced in Europe during the fourth quarter and in Asia in 2008.The user interface of the iPhone rests heavily on a high-resolution touch screen that makes it possible to use a finger to control the phone. It also has several more subtle features, including sensors that track light and movement to prompt the phone to control screen brightness and physical orientation and other aspects of its operation. For example, when the phone is placed next to the user's face, the keyboard is automatically turned off. One of the immediate questions that analysts and industry executives posed about Apple's new product was why the designers eschewed the higher-speed Cingular digital cellular 3-G network. Mr. Jobs said later models would support additional networking standards.

Proteja su computador contra software dañino

January 7, 2007 Tips for Protecting the Home Computer By JOHN MARKOFF Botnet programs and other malicious software largely take aim at PCs running the Microsoft Windows operating system, because Windows' ubiquity makes it fertile ground for network-based attacks. Using a non-Windows-based PC may be one defense against these programs, known as malware; in addition, anti-malware programs and antivirus utilities for the PC are available from several vendors. Windows users should use the Windows Update feature. Microsoft itself entered the computer-security business last year and now offers a free malware-removal tool for download from its Web site. The company says the program removes about two million pieces of malware each month, of which 200,000, or about 10 percent, are botnet infections. Like Windows, Microsoft's Internet Explorer browser is also a large, convenient target for code-writing vandals. Alternative browsers, like Firefox and Opera, may insulate users. Microsoft's most recent browser release, Internet Explorer 7, is said to offer significantly improved defenses. Adding software to your browser like Noscript, a plug-in utility, can limit the ability of remote programs to run potentially damaging programs on your PC. Security experts also offer these tips: ¶Don't share your computer (on which you pay your bills) with your children (who download games). ¶Use a firewall program that warns you about outgoing connections that botnets make to communicate with control software. ¶Don't use the same password on more than one financial site. ¶Don't let your browser store your password for such sites. ¶Don't buy anything offered by a spammer. ¶Don't click if someone offers you something too good to be true. It is. JOHN MARKOFF Copyright by The New York Times 2007

Ataque de los computadoras Zombie crece

January 7, 2007 Attack of the Zombie Computers Is Growing Threat By JOHN MARKOFF In their persistent quest to breach the Internet's defenses, the bad guys are honing their weapons and increasing their firepower. With growing sophistication, they are taking advantage of programs that secretly install themselves on thousands or even millions of personal computers, band these computers together into an unwitting army of zombies, and use the collective power of the dragooned network to commit Internet crimes. These systems, called botnets, are being blamed for the huge spike in spam that bedeviled the Internet in recent months, as well as fraud and data theft. Security researchers have been concerned about botnets for some time because they automate and amplify the effects of viruses and other malicious programs. What is new is the vastly escalating scale of the problem — and the precision with which some of the programs can scan computers for specific information, like corporate and personal data, to drain money from online bank accounts and stock brokerages. "It's the perfect crime, both low-risk and high-profit," said Gadi Evron, a computer security researcher for an Israeli-based firm, Beyond Security, who coordinates an international volunteer effort to fight botnets. "The war to make the Internet safe was lost long ago, and we need to figure out what to do now." Last spring, a program was discovered at a foreign coast guard agency that systematically searched for documents that had shipping schedules, then forwarded them to an e-mail address in China, according to David Rand, chief technology officer of Trend Micro, a Tokyo-based computer security firm. He declined to identify the agency because it is a customer. Although there is a wide range of estimates of the overall infection rate, the scale and the power of the botnet programs have clearly become immense. David Dagon, a Georgia Institute of Technology researcher who is a co-founder of Damballa, a start-up company focusing on controlling botnets, said the consensus among scientists is that botnet programs are present on about 11 percent of the more than 650 million computers attached to the Internet. Plagues of viruses and other malicious programs have periodically swept through the Internet since 1988, when there were only 60,000 computers online. Each time, computer security managers and users have cleaned up the damage and patched holes in systems. In recent years, however, such attacks have increasingly become endemic, forcing increasingly stringent security responses. And the emergence of botnets has alarmed not just computer security experts, but also specialists who created the early Internet infrastructure. "It represents a threat but it's one that is hard to explain," said David J. Farber, a Carnegie Mellon computer scientist who was an Internet pioneer. "It's an insidious threat, and what worries me is that the scope of the problem is still not clear to most people." Referring to Windows computers, he added, "The popular machines are so easy to penetrate, and that's scary." So far botnets have predominantly infected Windows-based computers, although there have been scattered reports of botnet-related attacks on computers running the Linux and Macintosh operating systems. The programs are often created by small groups of code writers in Eastern Europe and elsewhere and distributed in a variety of ways, including e-mail attachments and downloads by users who do not know they are getting something malicious. They can even be present in pirated software sold on online auction sites. Once installed on Internet-connected PCs, they can be controlled using a widely available communications system called Internet Relay Chat, or I.R.C. ShadowServer, a voluntary organization of computer security experts that monitors botnet activity, is now tracking more than 400,000 infected machines and about 1,450 separate I.R.C. control systems, which are called Command & Control servers. The financial danger can be seen in a technical report presented last summer by a security researcher who analyzed the information contained in a 200-megabyte file that he had intercepted. The file had been generated by a botnet that was systematically harvesting stolen information and then hiding it in a secret location where the data could be retrieved by the botnet master. The data in the file had been collected during a 30-day period, according to Rick Wesson, chief executive of Support Intelligence, a San Francisco-based company that sells information on computer security threats to corporations and federal agencies. The data came from 793 infected computers and it generated 54,926 log-in credentials and 281 credit-card numbers. The stolen information affected 1,239 companies, he said, including 35 stock brokerages, 86 bank accounts, 174 e-commerce accounts and 245 e-mail accounts. Sensor information collected by his company is now able to identify more than 250,000 new botnet infections daily, Mr. Wesson said. "We are losing this war badly," he said. "Even the vendors understand that we are losing the war." According to the annual intelligence report of MessageLabs, a New York-based computer security firm, more than 80 percent of all spam now originates from botnets. Last month, for the first time ever, a single Internet service provider generated more than one billion spam e-mail messages in a 24-hour period, according to a ranking system maintained by Trend Micro, the computer security firm. That indicated that machines of the service providers' customers had been woven into a giant network, with a single control point using them to pump out spam. The extent of the botnet threat was underscored in recent months by the emergence of a version of the stealthy program that adds computers to the botnet. The recent version of the program, which security researchers are calling "rustock," infected several hundred thousand Internet-connected computers and then began generating vast quantities of spam e-mail messages as part of a "pump and dump" stock scheme. The author of the program, who is active on Internet technical discussion groups and claims to live in Zimbabwe, has found a way to hide the infecting agent in such a way that it leaves none of the traditional digital fingerprints that have been used to detect such programs. Moreover, although rustock is currently being used for distributing spam, it is a more general tool that can be used with many other forms of illegal Internet activity. "It could be used for other types of malware as well," said Joe Stewart, a researcher at SecureWorks, an Atlanta-based computer security firm. "It's just a payload delivery system with extra stealth." Last month Mr. Stewart tracked trading around a penny stock being touted in a spam campaign. The Diamant Art Corporation was trading for 8 cents on Dec. 15 when a series of small transactions involving 11,532,726 shares raised the price of the stock to 11 cents. After the close of business that day, a Friday, a botnet began spewing out millions of spam messages, he said. On the following Monday, the stock went first to 19 cents per share and then ultimately to 25 cents a share. He estimated that if the spammer then sold the shares purchased at the peak on Monday he would realize a $20,000 profit. (By Dec. 20, it was down to 12 cents.) Computer security experts warn that botnet programs are evolving faster than security firms can respond and have now come to represent a fundamental threat to the viability of the commercial Internet. The problem is being compounded, they say, because many Internet service providers are either ignoring or minimizing the problem. "It's a huge scientific, policy, and ultimately social crisis, and no one is taking any responsibility for addressing it," said K. C. Claffy , a veteran Internet researcher at the San Diego Supercomputer Center. The $6 billion computer security industry offers a growing array of products and services that are targeted at network operators, corporations and individual computer users. Yet the industry has a poor track record so far in combating the plague, according to computer security researchers. "This is a little bit like airlines advertising how infrequently they crash into mountains," said Mr. Dagon, the Comic Sans MS Tech researcher. The malicious software is continually being refined by "black hat" programmers to defeat software that detects the malicious programs by tracking digital fingerprints. Some botnet-installed programs have been identified that exploit features of the Windows operating system, like the ability to recognize recently viewed documents. Botnet authors assume that any personal document that a computer owner has used recently will also be of interest to a data thief, Mr. Dagon said. Serry Winkler, a sales representative in Denver, said that she had turned off the network-security software provided by her Internet service provider because it slowed performance to a crawl on her PC, which was running Windows 98. A few months ago four sheriff's deputies pounded on her apartment door to confiscate the PC, which they said was being used to order goods from Sears with a stolen credit card. The computer, it turned out, had been commandeered by an intruder who was using it remotely. "I'm a middle-aged single woman living here for six years," she said. "Do I sound like a terrorist?" She is now planning to buy a more up-to-date PC, she said.   Copyright by The New York Times, 2007
