Cisco To Acquire OpenDNS
New submitter Tokolosh writes: Both Cisco and OpenDNS announced today that the former is to acquire the latter. From the Cisco announcement: "To build on Cisco's advanced threat protection capabilities, we plan to continue to innovate a cloud delivered Security platform integrating OpenDNS' key capabilities to accelerate that work. Over time, we will look to unite our cloud-delivered solutions, enhancing Cisco's advanced threat protection capabilities across the full attack continuum—before, during and after an attack." With Cisco well-embedded with the US security apparatus (NSA, CIA, FBI, etc.) is it time to seek out alternatives to OpenDNS? -
OpenDNS Phases Out Redirection To Guide
First time accepted submitter Jim Efaw (3484) writes "Tired of the OpenDNS Guide surprise from website-unavailable.com when you go to an old link or a typo from some ISPs? Relief is at hand: On June 6, 2014, OpenDNS will stop redirecting dead hostnames to Guide and its ads; the OpenDNS Guide itself will shut down sometime afterwards. OpenDNS nameservers will start returning normal NXDOMAIN and SERVFAIL messages instead. Phishing protection and optional parental controls will still stay in place." -
OpenDNS Releases DNS Encryption Tool
wiredmikey writes "It's not news that some of the underlying foundations of the DNS protocol are inherently weak, especially what they call the "last mile" — or the part of the internet connection between the client and the ISP. To address this, OpenDNS has released a preview of DNSCrypt, a tool that enables encrypted DNS traffic, much in the same way SSL enables encrypted HTTP traffic. DNSCrypt will stop DNS replay, observation, and timing attacks, as well as Man-in-the-Middle attacks and resolver impersonation attacks. The tool, available already compiled for OS X, will also run on OpenBSD, NetBSD, Dragonfly BSD, FreeBSD, and Linux. There is no Windows client, which is odd considering a majority of the 30 million OpenDNS users run Microsoft's operating system." -
Ask Slashdot: How To Combat IP-Based Censorship?
An anonymous reader writes "For a while now there has been a lot of buzz on a new proposed censorship scheme in Turkey. The government wants to crack down on freedom of speech and other rights by preventing us from accessing any websites it deems unsuitable. The reasons for that could be criticism of the government, pornography and basically anything a politician might dislike (YouTube is blocked for example — I'm not sure about Google, etc., because I'm bypassing the filter). Right now the state is using DNS-based filtering which can be circumvented with OpenDNS or proxy services which everybody knows about in Turkey. On August 22, however, a new scheme will go into effect that uses IP-based filtering. Bypassing this by any means is illegal, but I wanted to get some opinions on how this could be done without having to set up a VPN server outside of Turkey and using it as a private proxy." -
Happy System Administrator Appreciation Day
ArbiterOne writes "The 11th Annual System Administrator Appreciation Day is today. Celebrated worldwide on the last Friday of July, this day honors those who fight in the digital trenches to keep the Net alive. OpenDNS offers a way to remind your boss about the holiday, while another blogger shares war stories. The startup Ksplice has created an homage to these heroes in the style of Choose Your Own Adventure." Reader Netbuzz submits a sobering look at the profession from Network World, which notes, "In the past year, [sysadmins'] pay has dropped, and more of their positions are being farmed out to temporary workers." -
How CDNs and Alternative DNS Services Combine For Higher Latency
The_PHP_Jedi writes "Alternative DNS services, such as OpenDNS and Google Public DNS, are used to bypass the sluggishness often associated with local ISP DNS servers. However, as more websites, particularly smaller ones, use content distribution networks via embedded ads, widgets, and other assets, the effectiveness of non-ISP DNS servers may be undermined. Why? Because CDNs rely on the location of a user's DNS server to determine the closest server with the hosted content. Sajal Kayan published a series of test results which demonstrates the difference, and also provided the Python script used so you can test which is the most effective DNS service for your own Internet connection." -
OpenDNS To Block and Monitor Conficker Worm
Linker3000 writes "According to The Register, OpenDNS plans to introduce an new service that will prevent PCs infected with the Conficker (aka Downadup) malware from contacting its control servers, and will also make it easy for admins to know if even a single machine under their control has been infected by Conficker: 'Starting Monday, any networks with PCs that try to connect to the Conficker addresses will be flagged on an admin's private statistics page. The service is available for free to both businesses and home users.' With the amount of trouble this worm has caused, perhaps this is a good time to take a look at OpenDNS if you haven't done so already." -
OpenDNS As Quick-Fix To DNS Patch Dilemma
CWmike writes "It turns out that problems with the July 8 patch that was rolled out to fix a cache poisoning flaw discovered by researcher Dan Kaminsky are causing headaches for admins. Preston Gralla suggests a 30-second quick-fix, perhaps until everyone is patched up: Use OpenDNS, which has been patched, as your personal DNS. If you run a corporate network and need help getting OpenDNS set up, your best bet is to go to the OpenDNS FAQ page, he writes." -
Charter Implements SiteFinder-Like DNS
paulbiz writes "Charter Cable's DNS servers have just started resolving all invalid hostnames and pointing them to their own error page. The About page states: 'This service automatically eliminates many of the error pages you may encounter as you surf the web. No software was installed on your computer for this service to work.' It has an 'opt-out' page, but when you use it Charter simply sets a cookie that makes their page redirect errors to Microsoft Live Search instead!" One more reason to use OpenDNS, where you can actually opt out of the custom error page. -
Earthlink Offers Alternate DNS Without "Dead DNS"
Joshua Flory writes, "In response to the story about Earthlink and their version of 'Site Finder', I learned today that Earthlink has provided alternate DNS servers that will remain outside of their 'dead DNS' service. However, this is a completely unsupported service, which begs the question, WHY? Everyone can gain access to public DNS servers, or create their own. The point is that people wanted DNS servers supported by EL that do not include this dead DNS service." Sounds like it's time for Earthlink users to check out OpenDNS.com... they make it easy to turn off the bad-URL behavior. -
New(?) Anti-Fraud DNS service
knownsense writes "A new DNS system to foil spammers, abusers, and other ills of the Internet is around the corner, reports Wired. It claims to be more user-friendly than your ISP's DNS. Among its claimed advantages . . . Faster myspace(!?), coordination with spamhaus, and typo-squatter squashing. The actual service is called OpenDNS."
