Linux tip: Use “journalctl -f -u servicename” for real-time service logs. The “-u” targets specific service units, “-f” follows live output. Add “-p err” for errors only.

Linux tip: Use “systemctl mask servicename” to securely prevent a service from starting. Masked services can't start, even if they're enabled accidentally. “systemctl unmask” reverts the block.

Linux tip: Use the “setgid” mode bit on shared directories: “chmod g+s /shared/project”. New files will inherit group ownership, which prevents permission chaos between users.

Never trust untested backups. With Borgmatic, use `borgmatic check --verbosity 2` for repository integrity and `borgmatic extract --dry-run` to simulate restores. Schedule monthly tests.

Hey #Mastodon users running online servers,
I have a question:Is auto-ban IP for 24h systematically if they call well known ports without any service provided (FTP / SMB / ...) a good way to limit port scanners efficiency?

TIL (at 3 am): Upgrading Dovecot is not fun when the behavior changes a lot. Took several hours to get it running identical to before. But at least I could remove some old configuration parts.

Easy way to kickstart a runbook: Log actions with “history | tail -20 | tee file.md” to capture recent commands, then add explanations.

Linux tip: Use “ss -tuln” to check for open ports. Filter specific port numbers by adding “| grep :80”, for example.

If you want to raise your shell scripts to a new level, give this a try! It'll give useful feedback on the style of your shell code and on possible issues with it.
PS: Know when to switch to a proper programming language.

If your terminal ever gets confused by random control sequences, for example after you accidentally output binary data, there's a good chance you can restore order with the `reset` command.

Sooooo my recent mishaps with server administration are making me speed up my plans of shifting towards community-owned and -maintained hosting.
Ever since my conversation with @boris almost one year ago, I took his quote “self-hosting is selfish” as a mantra. It’s time to act accordingly.
Together with @Holly and @youjungnoh, we are putting together a group of tech-savy people who want to, respectively:
- Learn more about system administration
- Get their hands dirty while doing so
- Maintain our own shared server
- Host their own things (be them websites, projects, or services) together with comrades instead of individual infrastructure.
There are many super cool collectives that are doing this already, and we intend to draw inspiration from their work and their documentation, but we really want to do this together!
Who wants to join? Please, do reach out! I already spun up a small-ish VPS that is now hosting all my static websites. If you’d like to get involved, reach out and I would be happy to give you SSH access 🌻
We would also be very grateful if more experienced sysAds want to help us out by hosting workshops or brief classes.
We intend to meet for the first time in South Holland (but maybe virtually too) sometime during the first two weeks of March.
Next steps:
- Find a name for this group/server/mission
- Plan a series of (free, open) intro lessons with guests
- Start hosting some things
- Migrate things I am already hosting with YunoHost in our community server
- Migrate to a physical device in a home of ours?
EDIT: I forgot to add this, but it goes without saying that ours would be a queer and transfeminist server
