Preparing Your Enterprise for World IPv6 Launch
Things you should be doing even if you are not participating
Submitted by Scott Hogg on Sat, 05/19/12 - 3:35pm.
Last year on June 8, 2011 we all experienced World IPv6 Day. This was a 24-hour test for web sites to use both an IPv4 and IPv6 addresses simultaneously for the same URL. One June 6, 2012 there will be World IPv6 Launch in which many organizations will enable IPv6 forever. Enterprises will need to prepare for World IPv6 Launch whether or not they are actively participating and enabling IPv6.

My Take On Security IPOs
Infoblox, Palo Alto Networks, and Splunk
Submitted by joltsik on Fri, 04/20/12 - 10:07am.
Splunk (SPLK) went public this week and both Infoblox and Palo Alto Networks will soon follow. This could be the start of a security IPO run moving forward. Why? Status quosecurity defenses aren't working so there is a burgeoning market for next-generation security technologies. This market opportunity has driven M&A activities for years but we've recently seen far broader interest in security. HP grabbed ArcSight and started a security business unit. IBM acquired Q1 Labs and did the same. Dell purchased SecureWorks and SonicWall. Read more

Wikipedia parent finally ditching Godaddy over SOPA support
UPDATED: Wikimedia Foundation chooses MarkMonitor as new registrar
Submitted by Paul McNamara on Thu, 03/08/12 - 10:45am.
The Wikimedia Foundation, making good on a Dec. 23 promise by Jimmy Wales during the height of the anti-SOPA firestorm, has publicly announced it is transferring all of its domain names from GoDaddy to MarkMonitor as punishment for GoDaddy's early support of the failed anti-piracy legislation.

AT&T DSL: Getting What I Pay For?
By Mark Gibbs on Wed, 02/29/2012 - 4:24pm.
So, here in Gearhead last week I discussed the problems AT&T has been having in providing me with a reliable DSL service and it seems a significant number of you feel my pain.

Worst of SOPA out, White House bolsters opposition
ISP blocking provision to be removed; Lawmakers say ‘consensus’ needed
Submitted by Paul McNamara on Sat, 01/14/12 - 11:16am.
While it's far too early for SOPA opponents to declare victory, a trio of developments late last night and this morning make clear that concerted efforts to block or dramatically alter this ill-conceived antipiracy legislation are having a significant effect.
(Pics of near-riot, egging of Apple store in China)
Those developments: Read more

Reading up on SOPA can both clarify and muddy the waters
Dueling experts and pundits continue to slug it out
Submitted by Paul McNamara on Wed, 01/11/12 - 5:31pm.
Having spent a good chunk of the afternoon hopscotching from SOPA-related news story to blog post to social-media forum and back again, I'm thinking it might be worthwhile to point to a handful of the more notable stops. Read more

It’s Time to get Jiggy with Active DDI
DDI has been typically been something that only the biggest organizations with huge networks purchased. However, there are several strong forces such as IPv6, consumerization, mobility, virtualization and cloud that is making DDI an absolute must-have for organizations today. This will drive the evolution of DDI to Active DDI.

FBI takes out $14M DNS malware operation
NASA computers amongst 4 million infected by DNS-based malware scam
Submitted by Layer 8 on Wed, 11/09/11 - 3:28pm.
US law enforcement today said it had smashed what it called a massive, sophisticated Internet fraud scheme that injected malware in more than four million computers in over 100 countries while generating $14 million in illegitimate income. Of the computers infected with malware, at least 500,000 were in the United States, including computers belonging to U.S. government agencies, such as NASA. Read more

Swapping DSL modems, AT&T gets into the act
By Mark Gibbs on Wed, 09/28/2011 - 4:34pm.
My editor is being very understanding because this column is late, late, late. Why? Well, if you recall, last week I was wrestling my 2Wire 2701HG-B DSL Gateway trying to persuade it to recognize a really cool NAS device, the QNAP TS-1079 Pro, so I could enable port forwarding to expose the QNAP to the world.

Gibbs takes a look at a new QNAP NAS devices but his 2Wire DSL gateway doesn't help
By Mark Gibbs on Thu, 09/22/2011 - 12:00am.
"Currently 2Wire does not support Universal Plug and Play (UPnP). 2Wire customizes all gateway products and software to meet the requirements of our ISP partners. If supporting UPNP became a requirement, 2Wire will include the functionality to the system. UPNP allows the OS to control the firewall configuration that could have an adverse effect on any systems running behind a firewall that is being controlled by malicious software operating on a LAN-based computer."

Amazon denies being pressured to dump Wikileaks
Updated: Claims terms of service violated; Wikileaks calls company's statement a lie
Submitted by Paul McNamara on Fri, 12/03/10 - 11:08am.
Amazon.com is denying widespread reports suggesting that pressure from the office of Sen. Joseph Lieberman, chairman of the Homeland Security Committee, prompted it to boot Wikileaks from Amazon Web Services earlier this week.
Wikileaks replies that Amazon's pants are on fire.

Comcast outage encourages DIY DNS fix for some
Updated: Service disruption hits much of East Coast
Submitted by Paul McNamara on Mon, 11/29/10 - 9:06am.
Comcast customers on the East Coast looking to get an early jump on their Cyber Monday shopping last night were stymied by a DNS-related Internet service disruption. However, a number were able to fashion their own fixes to the problem after being directed to alternatives such as OpenDNS and Google Public DNS. Read more

Allow Both TCP and UDP Port 53 to Your DNS Servers
DNS queries are getting bigger so we do not want to accidentally block them
Submitted by Scott Hogg on Sun, 08/22/10 - 7:44pm.
Security practitioners for decades have advised people to limit DNS queries against their DNS servers to only use UDP port 53. The reality is that DNS queries can also use TCP port 53 if UDP port 53 is not accepted. Now with the impending deployment of DNSSEC and the eventual addition of IPv6 we will need to allow our firewalls for forward both TCP and UDP port 53 packets. Read more

Faulty firewalls and damaged DNS
By Mark Gibbs on Fri, 06/04/2010 - 12:00am.
Well, my tribulations with the Netgear eight-port Gigabit ProSafe VPN Firewall (model FVS318G) I discussed in the last installment of Gearhead appear to have been caused by faulty hardware.
To recap: I purchased one of these devices for my network and during the first few days of use my FVS318G randomly turned into a brick with pretty flashing lights that made it look like it was working when, in fact, it was not.

Google offers free, public DNS server
Google says its DNS server will make the Web faster and safer -- but is it too much power in Google's hands?
Submitted by Source Seeker on Thu, 12/03/09 - 5:22pm.
Google is planning on offering a free, public DNS server, adding yet another prong to its many-pronged attack on making the Web faster. With this move, anyone would be able to set up a browser to access Google's public DNS server, rather than using an Internet Service Provider or corporate DNS server. Read more

SRV Records and Active Directory, Part IV
What if there's no domain controller in a site?
Submitted by Glenn Weadock on Sun, 11/29/09 - 12:24am.
Today we get to take a look at one of the clever advantages of using SRV resource records in DNS to provide locator information for Active Directory domain controllers. Because Windows clients are “wired” to check DNS to find a DC, Windows can manipulate DNS to fool a client into thinking something that isn’t true! Read more

Submitted by Glenn Weadock on Mon, 11/23/09 - 4:07pm.
Earlier this month we discussed how special DNS resource records called SRV (service locator) records help Windows systems find domain controllers so they can authenticate to the domain. Interestingly, SRV records also help Windows systems find other kinds of important computers, too. Read more

SRV Records and Active Directory
How Windows Clients Find Domain Controllers
Submitted by Glenn Weadock on Mon, 11/16/09 - 7:46pm.
Any discussion of DNS and Active Directory must come quickly to a discussion of the AD “signposts” known as the SRV (service locator) records. SRV is just another resource record type, like A and PTR and MX. It is defined in the RFC 2782 document, which states that “The SRV RR allows administrators to use several servers for a single domain, to move services from host to host with little fuss, and to designate some hosts as primary servers for a service and others as backups.” Read more
