Containers present a hefty challenge for traditional firewall rules and iptables.
I was at the London Network Automation meetup this past week. London has a great community of network engineers that are eager to improve their current skill set and make their work lives easier. This meetup was geared towards learning new technologies around automation in the networking industry. There were talks about new ways to implement various existing automation tools, as well as real world discussions around how automation was implemented in the industry.
One common theme I experienced was how eager all network engineers are to open the scripts and code they write to administer their network devices. The sense of community and camaraderie amongst peers in this industry is one of the reasons I really enjoy working in this field. This is a real change in the industry. Even one year ago, the majority of network engineers did not have accounts on github or gitlab. Now, all these same network engineers exchange github and gitlab accounts like business cards. I couldn’t be happier with the direction this industry has taken.
However, I also couldn’t help but think about the irony of this situation. These creative and intelligent engineers are creating innovative scripts to shoehorn solutions into closed systems. Continue reading
New technologies such as IoT and cloud architectures are driving computing to the edge. Companies must embrace this trend in order to survive.
One person's deep artistic meaning is another person's network.
How Does Internet Work - We know what is networking
There is always the option to edit a file locally on your computer in notepad++ and then upload it to Cisco device. With this trick, you can write or edit a file from Flash memory directly from Cisco IOS console. If you need it for whatever reason, maybe to change something in the config file or something else, this is the way to do it. I was using if for my next article lab where I needed a file on the flash with at least 1600 bytes so I can pull it from neighbouring router with HTTP and check some
One of my readers sent me this question:
I'm in the process of researching SD-WAN solutions and have hit upon what I believe is a consistent deficiency across most of the current SD-WAN/SDx offerings. The standard "best practice" seems to be 60/180 BGP timers between the SD-WAN hub and the network core or WAN edge.
Needless to say, he wasn’t able to find BFD in these products either.
Does that matter? My reader thinks it does:
Read more ...On 11 October 2018, should ICANN roll the Root Key Signing Key (KSK) that is at the heart of DNSSEC? ICANN is planning to restart the rollover process for the Root KSK and is therefore seeking public review of their new plan. It includes more publicity about the need to be prepared for the rollover, and analysis of data indicating the level of preparedness.
The Plan for Continuing the Root KSK Rollover describes how ICANN intends to roll the root key signing key (KSK), and is based on input from the technical community following their decision to postpone the rollover last year.
Further input is requested by 2 April 2018. This will be used to prepare a final plan that will be presented to the ICANN Board for approval. ICANN is seeking public comments and we encourage you to read the plan and submit your views.
The Root KSK was originally planned to be rolled over on 11 October 2017, but ICANN postponed the rollover due to collected data that showed that a significant number of resolvers used by network operators were not ready for this. This meant that significant sections of the Internet could experience Continue reading
