I can spin up new VMs on the server in my living room and install software on it. But it's more complex than just installing the software on a baremetal server.

With years, I accumulated devices on my local network, which in general run on Linux. I meticulously added them to my /etc/hosts/ file, so as not to remember their IP. Something puzzled me, though: my Synology NAS was readily available as nas.local on the network, without doing anything. I have close to zero skills in system administration, so here are my findings.

We are happy to announce the next major 6.0.0 release of the VyOS Ansible Collection. It is now available from Ansible Galaxy and is also a certified collection for the Red Hat Ansible Automation Platform. If you are an active Ansible user, you surely noticed that the Ansible collection for VyOS lost its momentum at some point and remained stagnant for quite some time. Earlier this year, we had the repositories transferred to our organization on GitHub, took over the development, and formed...| VyOS - Blog

Until now, automating Proxmox cluster setups with Ansible often meant relying on hacky shell or command module usages within playbooks/roles and dealing with poor error handling.

We’ve always believed in building infrastructure like we write software: version-controlled, repeatable, and disposable when needed.

Ansible is a great tool for configuration management but because of the way it’s designed a common complaint is that it’s not as fast as other tools like Salt, Chef or Puppet. This is because Ansible doesn’t have an agent that listens (although it can) on a host and uses a different type of deployment methodology that is based on SSH. This post isn’t about the pros and cons of each tool, but rather about ways to improve upon Ansible’s default configuration values. By default Ansible...| Chris Bergerons Tech Blog

I’m limited to about 80MB/s on downloads on my VPC at Digital Ocean, but I run Nzbget for downloading large files from usenet. It doesn’t take long to download at all, but out of curiosity I wanted to see if I could parallelize this and download multiple files at the same. I use Sonarr for searching usenet for freely distributable training videos which then sends them to NZBget for downloading.

Knock Knock is a Sherlock from HackTheBox that provides a PCAP for a ransomware incident. I’ll find where the attacker uses a password spray to compromise a publicly facing FTP server. In there, the attacker finds a configuration file for a port-knocking setup, and uses that to get access to an internal FTP server. On that server, they find lots of documents, including a reference to secrets on the company GitHub page. In that repo, the attacker found SSH creds, and used an SSH session to d...| 0xdf hacks stuff

The feedback I received from the first comparison was great – thank you all. Obviously the example I used was not really something that you would use in the real world – because no-one actually creates a only a VPC – and does not create anything inside it, that is pretty futile.
