The post Noction releases IRP 3.9 appeared first on Noction.
Tech M&A this year includes hyperconvergence and software-defined WAN deals.
Netfortius made an interesting comment to my Ansible playbook as a bash script blog post:
Ivan - aren't we now moving the "CLI"[-like] approach, upstream (the one we are just trying to depart, via the more structured and robust approach of RESTAPI).
As I explained several times, I don’t know where the we must get rid of CLI ideas are coming from; the CLI is root of all evil mantra is just hype generated by startups selling alternative approaches (the best part: one of them was actually demonstrating their product using CLI).

More than one year after publishing a previous VyOS version, the new VyOS 1.1.8 is finally released. VyOS is an open source network operating system that can be installed on physical hardware or as a virtual machine. It is based on GNU/Linux and joins multiple applications such as Quagga, ISC DHCPD, OpenVPN, StrongS/WAN and others under a single management interface. VyOS is a cheap and effective solution for those who want to learn Junos like CLI.
Linux user can use my installation scripts for zero-touch VyOS deployment. Scripts download the newest stable VyOS x86-64 Live ISO image from web, create VMware VMDK disk and install VyOS from ISO on the disk. The scripts are available here (part 1.1).
Picture 1 - VyOS Version 1.1.8
Note: The scripts are tested on Linux with installed Qemu, KVM and Expect. First, run the Bash script deploy vyos.sh. The script downloads the latest VyOS ISO image. Then run the Expect script install vyos.exp that install on VyOS Live CD.
Whitespace handling is one of the most confusing aspects of Jinja2, thoroughly frustrating many attendees of my Ansible and Network Automation online courses.
I decided to fix that, ran a few well-controlled experiments, and documented the findings and common caveats in Whitespace Handling in Jinja2 video.
