Buying an iPhone 7 or iPhone 7 Plus may be impossible today

The iPhone 7 is already off to a booming start. Shortly after pre-orders began, Apple's carrier partners were blown away by unprecedented demand. Most notably, T-Mobile said that pre-orders were up 400% relative to the iPhone 6. Just yesterday, T-Mobile CEO John Legere added that the iPhone 7 is now the most pre-ordered device in T-Mobile history. On top of that, Sprint relayed that iPhone 7 pre-orders this year are up an astonishing 375% compared to last year. Suffice it to say, the iPhone 7 may very well set a new weekend sales record, though as we covered earlier, Apple won't be releasing specific sales figures this year.Speaking to the popularity of the iPhone 7, most prospective buyers hoping to walk into an Apple retail store and pick up the iPhone 7 model of their choice may be in for a rude awakening. According to a statement from Apple, all in-store stock of the iPhone 7 Plus and the Jet Black iPhone 7 are already sold out.To read this article in full or to leave a comment, please click here

Don’t pardon Snowden, lawmakers tell Obama

U.S. lawmakers are trying to stifle any hope that National Security Agency leaker Edward Snowden will receive a pardon. On Thursday, the House intelligence committee sent a letter to President Obama urging him to treat Snowden as a criminal.“Mr. Snowden is not a patriot. He is not a whistleblower,” the letter said.The letter was sent amid calls from tech leaders and liberal activists for Obama to pardon Snowden. The campaign, supported by Apple co-founder Steve Wozniak and celebrities including actor Daniel Radcliffe, argues that Snowden sparked an important debate about government mass surveillance.To read this article in full or to leave a comment, please click here

Multi-Chassis-Link Aggregation (MC-LAG)

In my earlier blog (Junos High Availability Design Guide) it was discussed how to make use of redundant routing engines by configuring features like (GRES, NSR, NSB)  for reduction of downtime to minimum possible level.

The real problem is that one RE is active at one time and all PFEs must be connected with active RE . In case of failure of primary Routing Engine (RE) the backup RE will take over  and all PFEs now, needs to connect to new primary RE. This scenario can cause momentary disruption of services.

MC-LAG (Active-Active) is correct solution to above described problem as it offers 2 active REs in 2 different devices/ chassis. Important concepts for MC-LAG proper configuration / functionality  are as under:-

  • Inter Chassis Control Protocol. The MC-LAG peers use the Inter-Chassis Control Protocol (ICCP) to exchange control information and coordinate with each other to ensure that data traffic is forwarded properly. ICCP replicates control traffic and forwarding states across the MC-LAG peers and communicates the operational state of the MC-LAG members. It uses TCP as a transport protocol and requires Bidirectional Forwarding Detection (BFD) for fast convergence. Because ICCP uses TCP/IP to communicate between the peers, the two peers must be connected to Continue reading

Time to move away from HPE Software

If you are still using HPE Software, you should actively plan to migrate away. The recent divestiture does not look good to me – I think existing customers are going to get soaked. Plan your migration now.

I’ve said it before, that I retain a soft spot for Hewlett-Packard. They gave me my first professional job out of university. I served my sentence doing HP OpenView consulting, and HP-UX Administration, but still: it got me started. Once you have some professional experience, it’s much easier to move to the next role.

It saddens me to watch HP’s ongoing struggles. It’s sad to watch a big ship get broken up for parts. But things had to change. They need to do something to adapt to the realities of modern IT demands.

There was one line in the recent announcement about divesting HPE’s software assets that stood out to me:

Micro Focus expects to improve the margin on HPE’s software assets by approximately 20 percentage points by the end of the third full financial year following the closing of the transaction

(Emphasis added).

It has been clear for a while that HP Software was no longer a core asset for HPE. It Continue reading

U.S. consumer agency issues official Samsung Galaxy Note 7 recall

The U.S. Consumer Product Safety Commission (CSPC) late Thursday issued an official recall of 1 million Samsung Galaxy Note 7 smartphones. Samsung had issued its own recall Sept. 2, but there was no formal recall in cooperation with the CPSC until now. The recall is necessary because the Note 7 "presents such a fire hazard," Elliot Kaye, the CPSC chairman, said in a news conference. Kaye said customers subject to the recall have two options: either to seek a replacement or a refund, "which is the choice of the customer and the customer alone."To read this article in full or to leave a comment, please click here

Junos High Availability Design Guide

High availability is one of the important consideration during network design and deployment stage and all most all the network vendors support various high availability features.

The objective of this article is to describe Junos best practices required to achieve minimum downtime in case of fail-over scenarios.

The Routing Engine or Control Plan is the brain in Junos based devices to run and execute all the management functions. Most of the  Junos based devices offers redundant routing engines (either through default configuration or through explicit configuration virtual chassis ). At one time only one Routing engine can be active (exception of Active-Active MC-LAG which is beyond the scope of this blog).  The mere presence of 2nd routing engine in the Junos device will not add any advantage with respect to high availability until certain features are not configured.

  •  Grace-full Routing Engine Switch Over  (GRES). GRES enables synchronization of kernel and chassis demon between mater routing engine and backup routing engines and in case of failure of master routing Packet Forwarding Engine (PFE) will simply join to new master routing engine (which was backup routing before fail-over).

Preparing for a Graceful Routing Engine Switchover

 

Graceful Routing Engine Switchover Process

GRES can be configured by following configuration command:-

The FBI could have saved money with this iPhone 5c hack

The FBI may have paid a small fortune to unlock an iPhone 5c used by the San Bernardino shooter. But a security researcher has demonstrated a way to do it for less than US $100. Sergei Skorobogatov at the University of Cambridge used a technique known as NAND mirroring to bypass the passcode retry limit on an iPhone 5c. Using store-bought equipment, he created copies of the phone’s flash memory to generate more tries to guess the passcode.   Skorobogatov detailed the whole process in a new paper that disputes the FBI’s assertion that the San Bernardino shooter’s iPhone couldn’t be accessed with the NAND mirroring technique.  To read this article in full or to leave a comment, please click here

Worth Reading: IPv6 versus v4 performance map

This is a world map showing the average value of the relative performance of observed connections in IPv6 compared to IPv4. The values are in units of milliseconds. For each observed dual stack end device, the TCP SYN exchange connection times are recorded and the best IPv6 and IPv4 Round Trip Times (RTT) are retained. …. Where IPv6 is faster, the IPv6 RTT is smaller than the IPv4 RTT and the result of the subtraction is a negative number, displayed as a shade of green in the above map. Where IPv4 is faster the result of the subtraction is a positive number, displayed as a shade of red in the map. —APNIC

Nenshou Fire: Recoil

My daughter has started a new fiction series on her blog; I’ll just link to it here for anyone who’s interested.

A cold circular object is pressed to my head, a hand reaching around to cover my mouth before I can make a sound. My eyes squeeze shut reflexively. Is this it? Is this how I’m going to die? After so much time of hiding, running, escaping the war around me, am I finally reaching the end of my life? My heart explodes inside me, waiting for the explosion of powder, marking the final moments of my life…but nothing comes. I open my eyes, surprised. What is this? Why hasn’t he made that one little motion that would end my life? —Nenshou Fire
