#Sysops

FrançoisThe systemd project was and is a *huge* leap forward for Linux. I can't imagine doing sysops without it.<a href="https://blog.tjll.net/the-systemd-revolution-has-been-a-success/" rel="nofollow noopener" translate="no" target="_blank">https://blog.tjll.net/the-systemd-revolution-has-been-a-success/</a>Update: suspected "AI" usage for the images in the post, in case you want to avoid this.<a href="https://floss.social/tags/systemd" class="mention hashtag" rel="nofollow noopener" target="_blank">#systemd</a> <a href="https://floss.social/tags/Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#Linux</a> <a href="https://floss.social/tags/sysops" class="mention hashtag" rel="nofollow noopener" target="_blank">#sysops</a>

Roni LaukkarinenBeen doing good shit lately - building clustered server stacks for some of the world's greatest corporations.I've been doing Bash programming for over 20 years, long before Puppet and Ansible came along, so I never really got into those technologies. I gave them a chance, but I prefer having full control, access to sources, and flexibility in my work. That's why I'm not a fan of the previously mentioned tools - or things like Tailwind and Docker. I love building my own tools and frameworks.<a href="https://mementomori.social/tags/Bash" class="mention hashtag" rel="nofollow noopener" target="_blank">#Bash</a> <a href="https://mementomori.social/tags/Servers" class="mention hashtag" rel="nofollow noopener" target="_blank">#Servers</a> <a href="https://mementomori.social/tags/SysOps" class="mention hashtag" rel="nofollow noopener" target="_blank">#SysOps</a> <a href="https://mementomori.social/tags/Sysop" class="mention hashtag" rel="nofollow noopener" target="_blank">#Sysop</a> <a href="https://mementomori.social/tags/Work" class="mention hashtag" rel="nofollow noopener" target="_blank">#Work</a>

Roni LaukkarinenSomething in the Managed Cloud hosting has always bugged me as a DIY dedicated hardware sysop guy. However, times change and currently I'm looking for one or setting up one myself for a site that has insane amount of requests per second. WP Engine, Pressidium, Pressable, Kinsta, WordPress VIP or custom AWS or what?

Roni LaukkarinenA while back I was super tired and had too many command line windows open. I typed in the wrong command on the wrong server. This caused system being partly broken, because I accidentally upgraded a held-back package. Eventually got it fixed by recompiling that certain package, but it contained a module compiled by an external party, so had to wait and not restart any services for 24 hours.Happens to all of us sometimes.However, what I learned is I should finally really change the color of each prompt for every single server I have. I have dozens of them. I'm lazy that way, I just customize my local prompt but rarely do it on production servers, despite how easy it is.For Mastodon my prompt is deep purple, like it should.```bash PS1="\[\e[38;5;141m\]\u@\h:\w\$ \[\e[0m\]" ```Here are my other prompts, feel free to use these colors in your .bashrc:```bash PS1="\[\e[38;5;99m\]\u@\h:\w\$ \[\e[0m\]" # Light Purple PS1="\[\e[38;5;141m\]\u@\h:\w\$ \[\e[0m\]" # Pastel Purple PS1="\[\e[38;5;183m\]\u@\h:\w\$ \[\e[0m\]" # Lavender PS1="\[\e[38;5;217m\]\u@\h:\w\$ \[\e[0m\]" # Light Pink PS1="\[\e[38;5;216m\]\u@\h:\w\$ \[\e[0m\]" # Peach PS1="\[\e[38;5;117m\]\u@\h:\w\$ \[\e[0m\]" # Sky Blue PS1="\[\e[38;5;159m\]\u@\h:\w\$ \[\e[0m\]" # Soft Cyan PS1="\[\e[38;5;121m\]\u@\h:\w\$ \[\e[0m\]" # Mint Green PS1="\[\e[38;5;229m\]\u@\h:\w\$ \[\e[0m\]" # Soft Yellow PS1="\[\e[38;5;210m\]\u@\h:\w\$ \[\e[0m\]" # Light Coral ```<a href="https://mementomori.social/tags/Linux" class="mention hashtag" rel="nofollow noopener" target="_blank">#Linux</a> <a href="https://mementomori.social/tags/SysOps" class="mention hashtag" rel="nofollow noopener" target="_blank">#SysOps</a> <a href="https://mementomori.social/tags/SysAdmin" class="mention hashtag" rel="nofollow noopener" target="_blank">#SysAdmin</a> <a href="https://mementomori.social/tags/Server" class="mention hashtag" rel="nofollow noopener" target="_blank">#Server</a>

Roni LaukkarinenJust spent 6 hours trying find out and solve why my Matrix instance is showing: {"errcode":"M_NOT_FOUND","error":"Not found"} when trying to access images. I did not notice this problem before, because Matrix/Element caches images locally using blobs, but realized this after uploading images to IRC via heisenbridge.I first thought I had messed up my S3 Object Storage. Then thought I messed up my filesystem. Then I thought I made a mistake in yaml configs. But it was none of that.It's a while since I installed my Matrix server and completely forgot on how I set up my S3 Object Storage. It seems it is literally not documented. Like at all. Just like the half of Matrix and Synapse.I ended up debugging literally anything and everything without any solution. After turning all stones I even asked ChatGPT and it started to run in loops in despair. Finally ended up reading synapse changelog here one bit by bit: <a href="https://element-hq.github.io/synapse/latest/upgrade.html#authenticated-media-is-now-enforced-by-default" rel="nofollow noopener" translate="no" target="_blank">https://element-hq.github.io/synapse/latest/upgrade.html#authenticated-media-is-now-enforced-by-default</a>It seems, I have upgraded in some point. And wow, in between of upgrades the whole thing has broken. I mean it runs without erros, but it's broken. No deprecated warnings in the log, no warnings in release logs. Left a comment here: <a href="https://github.com/element-hq/synapse/pull/17889#issuecomment-2564520513" rel="nofollow noopener" translate="no" target="_blank">https://github.com/element-hq/synapse/pull/17889#issuecomment-2564520513</a>My solution was to add in homeserver.yaml: enable_authenticated_media: falseWhat I hate about Matrix is:- Nothing is documented - Nothing is explained - Everything is complicated to set upEach upgrade and extension is like building and tinkering for hours and hours and hoping for the best.I don't know why I keep using Matrix.

I'm still in a sysop team and been doing servers for 20 years.Top 5: 1. Human error, someone restarted an erroneous process or crashed production in some way - deploy fails, workflow fails, etc. 2.

Larvitz :fedora: :redhat:Found this one in my basement today. It was the book, I used in my classroom training when I properly learned a programming language for the first time during my first job in 2002 (I had programmed before, but only on a surface level as a hobbyist)At this job, I was a Java backend developer for almost 7 years, at a company that developed software for logistics and fulfillment of pharmaceuticals. At some point, I even got the SCJD (Sun Certified Java Developer) certification 😆In 2010, my professional career as a software developer ended and I moved into IT-infrastructure and Consulting and I do Linux systems, open source and related technologies ever since. Mainly Linux Sysops, Container technologies and Ansible automation nowadays. (And hobby development in python and rust.
