Response: Why On-Premises Software Will Die Sooner
This is the most compelling article I’ve ever read about why on-premises applications/software are less competitive. I am reasonably certain that private cloud infrastructure can be as efficient as public cloud and cheaper over some period. What I’m coming to understand is that many of types of cloud-based applications may be much more efficent than […]

Is BGP Really that Complex?
Anyone following the popular networking blogs and podcasts is probably familiar with the claim that BGP is way too complex to be used in whatever environment. On the other hand, more and more smart people use it when building their data center or WAN infrastructure. There’s something wrong with this picture.

Forensic Lab Game Zero – Level 1 Results
The goal of the post is to provide solutions for the first level of the game for "hackers" created by forensic lab of CESNET association. With this game CESNET introduces a work of forensic analysts and test your knowledge of Linux OS. They are several assignments and practical tasks included inside Debian image which is available for download here. The question / answer sheet is located inside the home directory of user kassad.
Picture 1 - Answer Sheet
1. In the Linux image, which username is logged in automatically on boot?
Check the desktop environment.
kassad@debian1989:~$ echo $DESKOP_SESSION
gnome-fallback
Check if automated login is enabled for Gnome desktop.
kassad@debian1989:~$ grep 'AutomaticLogin' /etc/gdm3/daemon.conf
AutomaticLoginEnable = true
AutomaticLogin = kassad
The automated login is enabled for the user kassad. Now we need to compute the sha1 hash for the result.
kassad@debian1989:~$ echo -n 'kassad' | sha1sum
fb1216c760d6c0996991108886d1797d8bd4ca27
2. On the provided Linux image, what is the “ls” command aliased to for user from question 1 ?
kassad@debian1989:~$ type ls
ls is aliased to `ls --color=auto'
We can get the result also by checking the content of the file /home/kassad/.bashrc.
kassad@debian1989:~$ grep 'alias ls' /home/kassad/.bashrc
alias ls='ls --color=auto'
kassad@debian1989:~$ echo -n 'ls --color=auto' Continue reading

Supporting the transition to IPv6-only networking services for iOS
Early last month Apple announced that all apps submitted to the Apple Store June 1 forward would need to support IPv6-only networking as they transition to IPv6-only network services in iOS 9. Apple reports that “Most apps will not require any changes”, as these existing apps support IPv6 through Apple's NSURLSession and CFNetwork APIs.
Our goal with IPv6, and any other emerging networking technology, is to make it ridiculously easy for our customers to make the transition. Over 2 years ago, we published Eliminating the last reasons to not enable IPv6 in celebration of World IPv6 Day. CloudFlare has been offering full IPv6 support as well as our IPv6-to-IPv4 gateway to all of our customers since 2012.
Why is the transition happening?
IPv4 represents a technical limitation, a hard stop to the number of devices that can access the Internet. When the Internet Protocol (IP) was first introduced by Vint Cerf and Bob Kahn in the late 1970s, Internet Protocol Version 4 (IPv4) used a 32-bit (four-byte) number, allowing about 4 billion unique addresses. At the time, IPv4 seemed more than sufficient to power the World Wide Web. On January 31, 2011, the top-level pool of Internet Assigned Numbers Authority Continue reading

Building a “Network” Network
Over my years as a network engineer, I’ve notice that the engineering job tends to be somewhat isolated (or isolating). Part of the reason is probably that there tend to be one or two network engineers at a single company, munged in with a lot of other IT folks who share some common ground (but not entirely), so there’s little chance to interact with others who are working on the same sorts of problem sets on a day to day basis. This tends to produce network engineers who are more attached to their vendor than they are to their “day job.” In fact, this tends to make the entire network engineering world, to the average network engineer, appear to be “not much more” than the vendors who show up on our doorsteps, the vendor specific trade shows we can attend, and what we read online. This is—how can I say this gently—??
This is an unhealthy situation for your career as a network engineer—and as a person.
What you need to do is build a network of other network engineers—a network network—so you can broaden your scope, keep your ear to the ground for changes, prepare for changes, have Continue reading
