Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.

Our splicer, part funded by the campaign and a generous donor, has reached its intended location in Kharkiv, Ukraine and was immediately put to use. Here you can see our founding team member and driver Rene loading it into his truck in Ljubljana, Slovenia. This article was originally published over on Global NOG Alliance: The splicer has arrived — but we need more.
In technology terms a black is a full outage and a brown out is a congestion situation. The usual thing is that a blackout is debilitating while a brownout is an inconvenience. However, in many cases congestion is just as debilitating as an outage especially in the case of a network or even a service desk. Domino effect Let us assume that to deliver a resources we need 10 resources. These resources might be people, processes or tools. Now, assume there are only 9 resources. Logic would deduce that the delivery service would degrade by 10%. However, this is incorrect as the delivery of services immediately drops by 25%. This is because the impact of forcing other resources to try and close the gap, also reduces their effectiveness. Additionally, over time the service delivery starts trending further downwards because of a cascading dominoes effect where eventually a full outage situation might as well be declared. Thus if you have a service desks that
The madumbi farm In the midlands of Kwazulu Natal, a few kilometres north of the small town of New Hanover is the farm where I grew up. The farm is nestled in a beautiful valley where my father grew potatoes and cabbages and other vegetables including madumbis (read about them here ). The farm house was located on the one slope of the valley. It was a dusty house with wooden floors, red bricks and a green tin roof. Outside my window grew a glorious old wild fig tree. It was more on the side of being a hovel than a mansion. Tea Room We did not have television until the late seventies and then it was only a couple of hours a day with mostly government propaganda. My recollection of the Apollo moon landings were the interesting books and stickers that the Total fuel service station in town gave us. We never watched those landings live on TV like the rest of the world! Americans call a fuel service station, a gas station, but to us gas meant a fart. It
The life and times of BB These are the travels and the stories of Ronald Bartels, born a South African. The four corners of the Earth are where we have been, where we are, where we will be going and where we end up. When I was a baby my parents told me I was attached to my bottle and would not give it up. They concocted a story that they had to give it to the elephant in the Bloemfontein zoo to feed her babies. That was the last I saw of it, but every family gathering they would have great pleasure in retelling the story. never realizing that it wasn't appropriate to retell traumatizing events. These are my stories.

Bill Gates is a rich man. At one stage he was the richest. However, many people believe he is inherently evil because he funds vaccine research and as a result the conspiracy theories abound. His opponents have a number of problems and attempt to restrict his behaviour. They say he is no vaccine expert but ironically they think themselves qualified to make that observation to which they themselves invariably don't measure up. The fundamental point they miss is that Bill Gates has never himself done the work but hired the best in the world to do it and as such promotes it. At the heart of it all is an intellectual bigotry. It is similar to other forms of bigotry that exist and also abounds with name calling. Its juvenile behaviour that involves throwing insults and encouraging a few of your compatriots to join you in your crusade to malign an individual. None of it is rational or objective. It is all subjective and discriminatory. Heck, the phenomenon is not new. In the
MPLS migration MPLS has been used in the enterprise since the late 2000's and many networks are built using this technology. In reality it is still the significant majority. An MPLS network is used in a scenario where an organization has a number of geographically dispersed branches. These are interconnected using MPLS from network operators. MPLS is inherently expensive. A link to a branch averages out at about R12k while alternatives are in the region of R3k. Besides the cost, the implementation of these types of networks is difficult and time consuming. High level engineers are required and often extensive troubleshooting is required to operationalize deployments. MPLS is provided by the larger network opertors, the architecture requires long design, quote, order and implementation cycles. Configuration is also a complex undertaking that can lead to costly errors that take time to identify and fix. Extending MPLS networks into cloud hosting or to reach cl

Data security and data privacy have become increasingly important as the digital world becomes our reality. Laws and regulations have emerged to support this, and every industry now has some form of compliance requirement to keep data safe while maintaining industry standards. Networks and devices can be points of vulnerability that allow bad actors access to data, particularly now as more people are working remotely. A Software-Defined Wide Area Network (SD-WAN) can help organisations to secure both networks and devices to support compliance and ease data security challenges. Read the article published over at Engineering News by Amritesh Anand, Associate Vice President - Pre Sales at In2IT Technologies: How can SD-WAN help to ease data security and compliance headaches?
S oftware-defined networking (SD-WAN) underwent some fairly interesting changes in 2020. HPE acquired SD-WAN market leader Silver Peak, CloudGenix was bought by Palo Alto Networks, Juniper Networks bought 128 Technology, VMware acquired Nyansa, and Ericsson trundled off with Cradlepoint. Secure access service edge (SASE) technology continued down its own evolutionary path, a development that has bolstered the potential and capability of SD-WAN significantly. The two combine to create a far more agile and secure solution to the business that’s juggling remote working and an increasingly globalised workforce. In fact, a recent Forrester analysis pointed out that SD-WAN is the remote office in a box, but only if the investment into the technology is not a plug and play affair, but rather a long-term focus on skills, process, metrics and procedures that leverages automation and orchestrated service-chaining. This article published over at ITWeb is a deep dive into why any o
