Just push the button on the remote and you're scanning the airwaves.

Not all, but some pay providers still are gaining customers, not a net loss.

Back in the last century, when ZyXel was the modem name to look for, some SGI engineers had written fax software named Zfax for use with those modems -- it used to have such capabilities as you seek. For today, though, I'd advise trying the links that crop up when YaBinGling : zyxel Zfax Sender ID (or variations on that search string). HTH.

No sports fans here. Nor MTV fans, nor fans of much else that has lots of fans. But we are fans of CNN and BBC, and those seem to be available (to us, at least) only through a "premium" $30/mo. add-on bundle to a "basic" $70/mo. cable subscription -- not available OTA. FWIW.

Subject: Defeating the modern Leviathan Message-ID: <email@example.com> Defeating the modern Leviathan of corporate-government data collection Individuals face an unholy alliance of data-hungry private firms and public agencies. Only citizen action can win back our privacy by Bruce Schneier Imagine the government passed a law requiring all citizens to carry a tracking device. Such a law would immediately be found unconstitutional. Yet we all carry mobile phones. If the National Security Agency required us to notify it whenever we made a new friend, the nation would rebel. Yet we notify Facebook Inc. If the Federal Bureau of Investigation demanded copies of all our conversations and correspondence, it would be laughed at. Yet we provide copies of our email to Google Inc, Microsoft Corp or whoever our mail host is; we provide copies of our text messages to Verizon Communications Inc, AT&T Inc and Sprint Corp; and we provide copies of other conversations to Twitter Inc, Facebook, LinkedIn Corp or whatever other site is hosting them. The primary business model of the internet is built on mass surveillance, and our government's intelligence-gathering agencies have become addicted to that data. Understanding how we got here is critical to understanding how we undo the damage. http://www.theguardian.com/commentisfree/2013/aug/06/corporate-government-data-collection -or- http://goo.gl/GI3A0G -- Bill Horne (Remove QRM from my address to write to me directly)

Subject: Gone in 30 seconds: New attack plucks secrets from HTTPS-protected pages Message-ID: <firstname.lastname@example.org> Gone in 30 seconds: New attack plucks secrets from HTTPS-protected pages Exploit called BREACH bypasses the SSL crypto scheme protecting millions of sites. by Dan Goodin Aug 1 2013 Ars Technica The HTTPS cryptographic scheme, which protects millions of websites, is susceptible to a new attack that allows hackers to pluck e-mail addresses and certain types of security credentials out of encrypted pages, often in as little as 30 seconds. The technique, scheduled to be demonstrated Thursday at the Black Hat security conference in Las Vegas, decodes encrypted data that online banks and e-commerce sites send in responses that are protected by the widely used transport layer security (TLS) and secure sockets layer (SSL) protocols. The attack can extract specific pieces of data, such as social security numbers, e-mail addresses, certain types of security tokens, and password-reset links. It works against all versions of TLS and SSL regardless of the encryption algorithm or cipher that's used. It requires that the attacker have the ability to passively monitor the traffic traveling between the end user and website. The attack also requires the attacker to force the victim to visit a malicious link. This can be done by injecting an iframe tag in a website the victim normally visits or, alternatively, by tricking the victim into viewing an e-mail with hidden images that automatically download and generate HTTP requests. The malicious link causes the victim's computer to make multiple requests to the HTTPS server that's being targeted. These requests are used to make "probing guesses" that will be explained shortly. ... http://arstechnica.com/security/2013/08/gone-in-30-seconds-new-attack-plucks-secrets-from-https-protected-pages/ ***** Moderator's Note ***** This weakness is called a "known plaintext attack". If an attacker knows what is in an encrypted communication, and where it's located in the stream, (s)he can sometimes obtain the encryption key. Bill Horne Moderator

It has two RF inputs, one for an antenna and one for cable, with the requisite CableCARD slots and a USB connection for SDV. Because I don't have reliable OTA reception where I live, I usually have the broadcast channels disabled, but I configure my TiVo to think I have an antenna, so that I can switch over in just these sorts of cases. Can you or anyone else explain, by the way, why cablecos put the HD versions of various services (both local and national programming) on different "channel" numbers from the downconverted SD versions? The "channel" numbers are just arbitary digit strings, and back in the analog days they had no difficulty remapping channels affected by ingress interference; surely, now that everything is digital, it would make more sense for the decoder to use one "channel" number and select the correct program stream automatically depending on the type of device and customer authorization. (On my TiVo I disable all of the downconverted SD channels; if I used Comcast's equipment instead, they would not allow me to do this.) -GAWollman -- Garrett A.
