backstory Recently I helped someone out online (by providing a tiny pointer) with rootless containers and I realized that I might have some useful pointers (bits and bobs). These are somewhat related to my previous blogpost about JFrog - Xray and Insight.
In the last couple of years, I have had experience with running OCI (Open Container Initiative) compliant rootless containers with podman rootless and sometimes with docker rootless. Most docker-compose files and how to’s online focus on the root full variants, which you definately do not want.
JFrog is probably mostly known, because of their software product: Artifactory (artifact management software). But they also provide other pieces of software which integrate with Artifactory. For example they have XRay (security essentials) and Insight (DevOps intelligence tool).
Recently I was able to play around with both XRay and Insight (together with a good friend) to get those Java tools to run on a hardened Linux server, as a proof of concept.
Last week I talked to an excellent coworker at the office and we got talking about the Fallout TV series. Then we talked about Fallout 4 and I mentioned I started to play it a couple of months ago. He (thankfully) warned me about the recently released borked “next gen” update on Steam (sources: IGN, Rock Paper Shotgun, PC Gamer).
As a proponent of DRM free content, I prefer to buy games on Good Old Games.
Inoculation Science has 5 short videos to assist in resisting unwanted online persuasion.
They cover emotional language, incoherence, false dichotomies, scapegoating and ad-hominem attacks.
Due to recent news, I wanted to share this resource again. The more people are aware, the better. You will probably also recognize a lot of patterns used in media and discussions.
Video length is < 2 minutes per video and they can be found on the main webpage and on this youtube playlist
Ever since I switched to podman, I really appreciated the rootless setup. Something about increased security.
Recently I had to help someone out with docker rootless and I was really missing podman unshare. Which basically is the unshare subcommand. Luckily something similar exists, which can be used for docker rootless, namely nsenter.
To execute a command in the namespace of the docker rootless daemon, you can use this:
nsenter -U --preserve-credentials -n -t $(pgrep dockerd) somecommand
Recently I started playing Fallout 4 by Bethesda via Steam on my Ubuntu desktop with Awesome WM.
Quite quickly in the game (once you gather different bits of ‘junk’ and other pieces), you will get annoyed by the fact you can not do a simple search in a cabinet/container for an item. You have you manually scroll through the entire list and I was fed up with that. Luckily there appears to be a perfect mod to fix this issue: Fall UI - Inventory.
Recently I had to use the nsset commandline tool, which can be used to modify the DNS records of your Ubuntu LoCo (Local Community). The nsset tool can be found on the LoCo Teams DNS Admin wiki page in the attachments section. Just want to say that I really appreciate this tool and want to thank all contributors!
I’ve discovered a bug (deprecation actually), which I can not fix. To be honest, I am a SysAdmin and not a programmer.
Mozilla Firefox has been a privacy-first browser for years and is excellent. Recently I found my way to (yet another page on the excellent) page on the Arch wiki, about Firefox privacy. There I found out about the following setting (which can be modified in about:config) to increase/enhance your privacy to resist fingerprinting even more:
privacy.resistFingerprinting The wiki page includes a warning (which, I hoped for, would have been exaggerated). It made me find a bug in the website of a primary school, but also broke DRM playback for a major streaming service.
Veeam has a plugin for Oracle RMAN. Unfortunately this plugin encountered a slightly grumpy sysadmin who wants to keep servers secure.
the documentation In the the official documentation they state to run the tool and it should just work. We got the following output (I’ve omitted the output after the error):
user@host:~$ ./OracleRMANConfigTool --wizard Enter backup server name or IP address [hostname]: Enter backup server port number [10006]: Enter username [username]: Enter password for username [(do not change the existing password)]: Available backup repositories: 1.
Somewhat recently I was reading about x265 (High Efficiency Video Coding (HEVC)) and noticed it had quite some (space) advantages over its predecessor x264 (Advanced Video Coding (AVC)). I have a large family video collection (which keeps growing) and thought I might save some space and bandwidth, by converting them from 264 to 265. Reading up on my GPU ( 6600 XT ) specifications, it should support hardware encoding! Then my time got consumed by other projects, until…
