Hello everyone! I know that there are many resources on OpenVPN settings. However, I found that there is a lack of systematic information on the topic of the title and decided to share my experience primarily with those who are not gurus in OpenVPN administration but wish to achieve site-to-site connections for remote subnets on a Synology NAS.

It seems that the developers of Terraform provide quite convenient best practices for working with AWS infrastructure. However, there’s a catch. Over time, the number of environments increases, each with its own peculiarities. There’s an almost exact copy of the application stack in the neighboring region.

I made the following key points […]
As we prepare for the launch of a new set for the 'Databases' course, we continue to publish a series of articles on encryption in MySQL. In the previous article in this series, we discussed how encryption works with the master key. Today, based on the knowledge gained earlier, we will look at the rotation of master keys. Master key rotation involves generating a new master key and using this new one […]
tl;dr: I am building an image of Kali Linux for an ARM computer using debootstrap, linux, and u-boot. If you purchased a less popular single-board computer, you may have encountered a lack of an image for your favorite distribution. A similar situation occurred with the planned Flipper One. There is simply no Kali Linux for IMX6 (I'm preparing it), so I have to build it myself. The boot process is quite […]
