Setting up a cracking box using Paperspace

Today I've solved the problem of one server being to slow to handle the growth of my zabbix configuration. I'm using zabbix-server 2.2.2 with MySQL/Debian backend and around 20 zabbix-agents with Debian installed.

Let's say old Zabbix server IP is: A.B.C.D and new is: U.X.Y.Z. The domain name for the instalation will be: http://zbx.newmachine.com

Below you will find all steps to migrate your configuration:

Ensure all agents will accept connections from the new IP Modify each agent configuration file (in debian: /etc/zabbix/zabbix_agentd.conf) and add new IP

This note explains the common issue of "notapplicable" results when running openSCAP and SCAP-Security-Guide on CentOS.

SCAP seems like it should be easy because it is "just XML". Then you dig into looking for a test and it gets confusing fast. So it is good to have some background.

SCAP (Security Content Automation Protocol) is actually a set of multiple standards and specifications that are used together to enable automatically testing hundreds of nerd settings. Let me emphasize that: SCAP is not a single XML specification -- SCAP is multiple standards and specs. Whenever you give "SCAP Content" to a scanner to check a system configurations you are giving the scanner multiple XML files representing multiple standards.

Overview: running crc on a remote server

This document shows how to deploy an OpenShift instance on a server using CodeReady Containers (crc) that can be accessed remotely from one or more client machines (sometimes called a "headless" instance). This provides a low-cost test and development platform that can be shared by developers. Deploying this way also allows a user to create an instance that uses more cpu and memory resources than may be available on his or her laptop.

While there are benefits to this type of deployment, please note that the primary use case for crc is to deploy a local OpenShift instance on a workstation or laptop and access it directly from the same machine. The headless setup is configured completely outside of crc itself, and supporting a headless setup is beyond the mission of the crc development team. Please do not ask for changes to crc to support this type of deployment, it will only cost the team time as they politely decline :)
