Note: Debian 9 Stretch reached end-of-life in June 2022. The compile-from-source method shown here is still valid on any current Debian or Ubuntu system — just substitute the Python version you need. I recently spent 30 minutes figuring out how to upgrade to python 3.7 and subsequently pip version on a fresh install of Debian 9. I ran into a number of issues doing this so I though that I would put this quick post together to make this a little bit less complicated for anyone else trying to this. ...

This is a local DNS server for local DNS requests. This post is going to explain the why and how I created a local DNS server in my home network environment. I used the PiHole project to make a network wide advert blocking a reality. https://pi-hole.net/ I have previously created a DNS server using Bind, running on CentOS 7. Thankfully digital ocean came to my rescue with some of the config in this home lab project, so be sure to check out their guide if you are looking for slightly higher level DNS setup: https://www.digitalocean.com/community/tutorials/how-to-configure-bind-as-a-private-network-dns-server-on-centos-7 ...

It is easily possible to use Read-Host to make this a little bit more interactive, but the purposes of my use-case it was just as simple to modify these variables before running the script. ...

Perhaps it is a case of a website which prevents text form being sent to a field from the clipboard, or in my case, a windows UAC prompt. If you are following password best practices, your passwords should be long, complex and contain zero dictionary words. Furthermore, you should have a different password for every site and service. So, when a user interface doesn’t allow you to paste a password, life gets that little bit more difficult. ...
