FTDI Reportedly Bricking Devices Using Competitors' Chips.

ptudor Re:Bad for Biz (595 comments)

Amen. I just received a handful of FT323RLs in the mail today from Mouser. It costs 5x as much as a Chinese import, but this certainly isn't the first time FTDI has used driver updates to protect their technology, it's just the first time (that I know of) they've actively disabled chips. But if FT-Prog can fix them, great.

Anyway, there are cheaper alternatives, I'm growing fond of the WCH CH340/341 series for being a tenth of the price of an FT232. But it requires driver installation, whereas MacOS just works with FT232s.

I mean, I even address that in eBay listings for products built on CH340s ("this is $4 cheaper because you have to install drivers, and it's known to not be counterfeit") and in my products using the FT232RL ("It costs more, but you just want it to work, right?"). Like my USB GPS adapter.

What To Do If Police Try To Search Your Phone Without a Warrant

ptudor Legal protection, and reality (286 comments)

Most people involved in a pre-textual motor vehicle stop and issued a warning for a trivial non-offense won't know to say the magic words that begin their legal defense: "Am I free to go? Why am I being detained?" and when the polite officer says, "Well, I'm sure you've got nothing to hide, let me search your vehicle, and no matter what I'll make sure you're on your way quickly," many quickly hope compliance is their best option in the short-term.

So they say, "Yeah, go ahead," instead of the alternative, "I do not consent to search and invoke all protections afforded me by the Constitution; while I am cooperating within those constraints, please advise me promptly when I am free to go."

You'll get searched anyway, whether it's your phone or your car. You might get arrested anyway. But having invoked your rights instead of freely waiving your rights gives the defendant ample opportunity to assert their innocence in court without having already accidentally proven their guilt without the benefit of counsel.

I expect most people, despite the Supreme Court ruling, will find their phones searched anyway; consider stop-and-frisk in New York City. Please set a passcode on your device, preferably alphanumeric instead of a simple PIN, and avoid interacting with law enforcement, they have better things to do than read a neckbeard hacker's text messages to his mom about picking up more Mountain Dew at the store.

(Nevermind Border Patrol checkpoints in the US or Customs/Immigration interviews...)

Nagios-Plugins Web Site Taken Over By Nagios

ptudor Alternatives... (119 comments)

After having the good fortune to spend a few weeks testing everything free, I've got to spend a minute evangelizing for Zabbix.

It took me a week to understand the concepts, but the clone button and templates make Zabbix my favorite tool. The local Zabbix agent on each host gives detailed metrics and the screens of graphs are great.

Check out the appaloosa-zabbix-templates for more MySQL and Memcache charts than you ever thought might work out of the box.

Zabbix is ridiculously powerful, from auto discovery on subnets, to simple ping and snmp, up through more advanced tools.

Security Expert: Yahoo's Email Encryption Needs Work

ptudor Re:Even good ciphers are mostly useless (123 comments)

I'd add a #4, or #2a, Man-In-The-Middle the certificate. Diginotar's compromise, never the huge bundle of trusted certificates in every browser/OS, makes it easy. Whatever an enterprise can do with GPOs and Websense can happen in the wild too. (I kinda prefer self-signed certificates anymore.)

Overall I agree, but I still cry out in pain when I see people choosing to use 3DES and disable PFS.

Security Expert: Yahoo's Email Encryption Needs Work

ptudor Progress. (123 comments)

It's important to remember that only a year ago RC4 was a recommended solution and TLS1.2 support in browsers like Firefox and older operating systems has been slow to arrive. So I look at this as an important first step, with progressive refinements sure to follow. In the same way that Facebook introduced https in response to Tunisia and slowly made it an option for all users before making it default, Yahoo, while slow in adopting a model of default security, has to walk similar steps. They may have had an SSL-beta-option for the last year, but given their AOL-Like user base, I can understand being conservative in adopting new methods and being liberal in the ciphers they provide. Someone using Chrome in Mavericks may expect support for SPDY3 with AES-GCM, but for a user base that may be using IE6 or FF3 on XP still, for a company that caters to people who will never know what GCM or SHA2 is it best to avoid the headline, "Yahoo Mail is Broken for tens of thousands of users." They'll get there. Thanks for trying, Yahoo.

Now, can someone at Microsoft turn on STARTTLS? For that matter, I wish NANOG would turn on STARTTLS for inbound connections.

Also, IPv6... please... IPv6...

Why Can't Big Government Launch a Website?

ptudor Government success: DNSSEC (786 comments)

The headline could do without that loaded word "big" and the connotations it brings. An easy counterpoint is DNSSEC: The entire dotgov TLD has had DNSSEC deployed for years in stark contrast to the adoption rate among the general population. Complex projects in technology are not all alike.

George "geohot" Hotz Arrested In Texas For Posession of Marijuana

ptudor End Prohibition Now (578 comments)

Eighty years ago, alcohol was unconstitutional. Temperance unions succeeded in making dry counties a dry country and organized crime profited. Cannabis had not yet been vilified in place of beer.

Today, Budweiser advertisements can occupy an entire subway car on the New York MTA while the NYPD ensures >85% of those arrested for simple possession in both 2010 and 2011 are black or brown. What wasted resources! What an undue burden on citizens!

We must end the prohibition of cannabis. We must return justice to our courts. We must turn a black market into a taxed market. We must embrace research demonstrating controlled apoptosis in various cancers. You must join me. Prohibition harms everyone.

Iran Shuts Down US Virtual Embassy

ptudor Re:U.S. (451 comments)

Al-Jazeera is a Qatari network, not Iranian. The difference is quite a gulf.

Functionally, companies in the United States block Al-Jazeera. I challenge you to actually watch their CNN-like feed on your local cable station. The best I can do is their half-hour daily news program broadcast alongside BBC America and (that wretched) RT News on KCET in Los Angeles; today I consider Al-Jazeera's reporting premeir among broadcast television.

We at slashdot all know it's easy to intercept and redirect DNS (unless you're in Sweden, those fine adopters of DNSSEC), or insert in a transparent Squid/whatev with a hosts file, but I'm confident at least they're probably not using Websense, years ago I installed the mod_geoip ruleset to deny access to daily updates for requests originating from embargoed nations.

Last time I was in Syria Facebook was blocked at the port 80 level. But ssh forwarding 3128 worked fine, hopefully no one was etherealing 53. Funny it took Syria three years to finally ban iPhones, I lost a brand-new 3G getting out of a taxi in Damascus... the one time I didn't photograph the license plate of the car I was getting into.

Seeing "Persian" instead of "Farsi" struck me as odd, but I suppose I'm the odd one.

How To Catch a Laptop Thief?

ptudor Re:The other side (485 comments)

html5 geolocation tends to look at the MACs of nearby BSSIDs to assist in the triangulation. It's not just MaxMind-style tables of IP addresses anymore, check out Google Location Services (used by firefox). It combines four elements: IP addresses, Cell Triangulation, nearby access points, and GPS. Blaming wifi for misdirection is plausible, but it also indicates that stolen property was perhaps next-door or across the street.

Vint Cerf Says No To IPv7, Yes To InterPlanetary Web

ptudor Re:So much for R&D and innovation -- (108 comments)

I do not miss your point, I make mine that R&D advances best with a common capable foundation. Ethernet addressing is static, yet Ethernet interfaces advance. IPv4 has been static since RFC1918, yet applications on it have evolved. People will find new uses for multicast and peer-to-peer communications in IPv6. The methods behind DNS haven't changed much since the end of the global hosts file, yet new record types like SRV, AAAA, and RRSIG can arise because of the sublime framework that underlies name resolution.

I mention an encouragement for adoption because remaining with IPv4 works against both our interests, yours in the continuing innovation -- we can't have IP-next-next-gen until we have an IPng network that bests the legacy IPv4 -- and mine in restoring the Internet to its peer-to-peer model.

"Privacy Extensions" address your concern about trackable addresses in IPv6. Browser cookies are a much greater threat to personally identifying a unique machine as it moves from location to location but nonetheless Windows by default enables the generation of a random host address and on linux grep sysctl to enable temp_addr.

Vint Cerf Says No To IPv7, Yes To InterPlanetary Web

ptudor Re:So much for R&D and innovation -- (108 comments)

IPv6 dual-homing was still in progress.

I had IPv6 BGP with PI space in late 2006, so... uh...

I'll also add two comments concerning stagnation of technology. 1) MAC Addresses haven't changed in a long time. Yet Ethernet continues to advance, from coax to twisted pair, wireless, and fiber and from a bus to hubs then switches and now L3 switches. (although where are my end-to-end Jumbo Frames already?). A capable foundation does not hinder innovation. 2) Globally unique addresses in applications are the key. Returning the Internet to its mid-90s status quo of every host being a unique peer enables technologies that are simply painful to adopt today, like SIP communications or IPsec between islands of NAT. So we have created an inefficient clientA-server-clientB bandage so people can send each other images in IMs or actually use their webcams. Once the software developers (yes, they're part of my presentations) grasp the advantages of IPv6 I can't even imagine the wonderful new ideas they'll deliver.

IPv4 is simply unsustainable: at some point we'll simply run out of ports per IP to use for PAT. IPv6 has enough addresses to last effectively forever, through the lifetimes of people born today. Versus the status quo, where each person on earth has about half of an IP address if you consider the overhead of VLSM, not enough to cover my mobile phone, my SIP phone, my iPod, my iMac, my MacBook, my colocated servers, nevermind all the nerds in India or China... Would people adopt IPv6 faster if they saw it as a matter of social justice and equal access to technology for all the children of the earth?

(P.S. Everyone please hire me and some of my friends to teach IPv6 classes at your organization and organize your deployment. Thanks)

Allegations regarding OpenBSD IPSEC and FBI code

ptudor (22537) writes "Gregory Perry has emailed Theo de Raadt, claiming 'the FBI implemented a number of backdoors and
side channel key leaking mechanisms into the OpenBSD Crypto Framework' as the reason 'inside FBI folks have been recently
advocating the use of OpenBSD for VPN and firewalling implementations in virtualized environments.' de Raadt notes because OpenBSD 'had the first IPSEC stack available for free, large parts of the code are now found in many other projects/products' he is making the allegation public so 'those who use the code can audit it for these problems.' A decade of changing code leaves it 'unclear what the true impact of these allegations are.'"

Passport Cards For Border Towns Now Shipping

The article continues, 'Federal officials announced Tuesday that the wallet-sized cards are in production and that those who preapplied for them starting in February should be receiving theirs by Sept. 30. More than 350,000 people have ordered passport cards and at least 7,600 have been mailed, according to the State Department.' The initial press release from the State Department is available as well as a FAQ on the new cards."
