Introduction

Zabbix is an open-sourced tool used to monitor various IT components such as servers and hardware that they are running, cloud services, whole networks, etc. Zabbix can monitor the network health and integrity of your servers. All monitoring can be done through Zabbix’s web-based frontend. This means that you can quickly check the status of your servers from anywhere! This article describes how to install the Zabbix monitoring tool, create a database, and configure the frontend on Ubuntu 20.04.

Introduction

In this article, we will be exploring GnuPG or GPG as it is more commonly known. We will discuss if this software platform is still needed, if it will still be useful in the future, and how to install and utilize it. 

What is a Python Function? 

In this tutorial, we discuss one of the most useful attributes of Python: the function. Python functions are considered “First Class” objects. A First Class object can be assigned to variables, stored in data structures, passed as arguments to other functions, or even return values from other functions. Other examples of First Class objects in Python are integers, strings, and dictionaries.

Introduction

Just as regular visitors reach our server every day, so do others with more nefarious intentions. It is simply not reasonable to run an online service without some layer of protection. To protect against some of these attacks, Ubuntu ships with ufw (Uncomplicated Firewall). This is a tool designed to make Ubuntu firewall management as easy and user-friendly as possible. Specifically, ufw provides a cleaner interface for the core firewall tools netfilter and iptables, which, while robust, can be challenging to master.

What is ClickHouse?

ClickHouse is an open-source column-oriented DBMS (or database management system) primarily used for OLAP (or the Online Analytical Processing of queries). It is capable of blazing fast generation of real-time analytical data and reporting utilizing SQL queries. It is fault tolerant, scalable, highly reliable and contains a feature rich tool set.

What is ArangoDB?

ArangoDB is a high availability and scalable multi-model NoSQL database that natively works with graphs and documents and includes a full-text search. It is a free, open-source software developed and maintained by ArangoDB GmbH. The system supports three different data models with one database core and includes a unified query language called AQL (ArangoDB Query Language). This query language is declarative and allows the combination of different data access patterns in a single query. The software can be implemented on multiple systems, including Windows, macOS, Linux, Kubernetes, Docker, and on our Managed Cloud. It has a strong community support base on GitHub, StackOverflow, Google Groups, and Slack. 

One of the most significant advantages of Python is how easy it is to reuse existing code. 

What is Bashtop?

What is Django?

Django is a Python-based web framework that is used for developing complex, database-driven websites. It also operated under an open-source license indicating it is free to use. Django is ultra-fast and encourages security, and it is exceptionally adaptable, which is the cause of its immense popularity.

This article will discuss the methods to send information securely over email using GPG/PGP as the main encryption tool. The difference between PGP and GPG is mainly that PGP is a proprietary solution controlled by Symantec, and GPG is the open-source standard that is defined by RFC 4880. Functionally, each format is virtually identical due to GPG being the offspring of the original PGP standard. Because there are numerous email clients, specific GPG settings will vary. For this tutorial, we will use Gmail and Thunderbird as examples.
