#systemadministration — Public Fediverse posts

Hello #Mastodon! First post here.

I've been developing mend: a Zsh-native recovery tool for #ArchLinux. It maps terminal exit codes to the Arch Wiki using #fzf.

v0.4.0 is live. Short demo video attached. (1/2)

#Linux #OpenSource #Zsh #TUI #SystemAdministration #AUR #Mend

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.

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:

1. Learn more about system administration
2. Get their hands dirty while doing so
3. Maintain our own shared server
4. 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:

1. Find a name for this group/server/mission
2. Plan a series of (free, open) intro lessons with guests
3. Start hosting some things
4. Migrate things I am already hosting with YunoHost in our community server
5. 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

My website is probably down, my server is broken because yesterday out of the blue I decided to upgrade to the major @yunohost beta even though it was the last thing I was supposed to be doing. WHYYY do I have to follow this impulses doomed to faaail?

I made a mess and now I am stuck 🫠

Any help is welcome, I also accept commiseration if there is no other choice 😩

What I believe has happened is that I updated dependencies to Debian Trixie but the system and YunoHost are still in Bookworm, but I can’t really say 🤔

I wrote about it here. Tons of gratitude to anyone who will decide do spend a tiny bit of their weekend helping me 💕

Hi fedi folx. I was laid off just before the start of the year. This is a reach out for support, not in the monetary way but in an information and connections way.

I'm wanting to use this as an opportunity to work for organizations who's values I can support. I am looking for a remote role, working with a nonprofit.

I'm a chronically ill trans person in the US. A sys admin with 5 years experience, mostly in the windows ecosystem with some moderate Linux experience. I have done some containerization and virtualization. I love to improve systems, processes and security.

It has been nagging me a lot, but I finally decided to shut down my Pixelfed server.

There are several reasons. Here are the ones off the top of my mind.

• Pixelfed governance is unclear and its maintenance is spotty and obscure. The project has no clear roadmap and it all feels very off. Even though I was enthusiastic about @PixelfedGlitch, it still seems like this fork is not attracting enough interest and participation to establish a forward-looking plan.
• Beyond governance, I share these concerns.
• I don’t want to maintain a whole instance merely for a single profile—especially after it has been inactive for a long while. Friends and folks who are curious and interested in exploring the Fediverse are welcome to join pan.rent, that is a collective, communal, and cosy instance.
• I am having trouble with the pixelfed_ynh package for YunoHost. PHP dependencies are a mess and services constantly fail. I believe it’s not the fault of YunoHost packaging, but I am no expert, just a feeling. No energy and not worth figuring it out. I tried for a while, I gave up.
• I am generally against the idea of having multiple Fediverse accounts on multiple servers for different uses. Instead, I believe we should improve filtering and sorting posts depending on their type, and having one single account linked to one identity. Overall, Mastodon Glitch Edition does the job for my occasional image and video posting, even if it’s not optimal.
• I want to use the domain https://tmi.pics for a different purpose, probably an Immich server.

Now, a question for all the sysads out there: what are the best practices you recommend before shutting the server down? I have a strong emotional attachment to the ~15 pictures and posts I have on my profile there.

What I am doing, so far:

• saving all Web pages of profiles and posts on the Wayback Machine
• performing and archiving a YunoHost backup of the application
• ?

GT-CLPM: مدير الحزم الشامل الذي طالما انتظرته مجتمع Linux

📖 المقدمة

في عالم Linux المتنوع، يواجه المستخدمون تحديًا دائمًا في التعامل مع أنظمة إدارة الحزم المختلفة. كل توزيعة لها مدير الحزم الخاص بها: APT لـ Debian/Ubuntu، DNF لـ Fedora، Pacman لـ Arch، وهكذا. هذا التنوع، رغم كونه ميزة، يمكن أن يكون مصدر إرباك للمستخدمين، خاصة الجدد منهم.

GT-CLPM يأتي كحل ثوري لهذه المشكلة - مدير حزم موحد يعمل على جميع توزيعات Linux تقريبًا!

🎯 ما هو GT-CLPM؟

GT-CLPM (GNUTUX Command Line Package Manager) هو مدير حزم شامل مفتوح المصدر، صممه المطور SalehGNUTUX، بهدف تبسيط إدارة الحزم عبر توزيعات Linux المختلفة من خلال واجهة سطر أوامر موحدة وسهلة الاستخدام.

✨ المميزات الرئيسية

• 🌐 دعم متعدد اللغات: واجهة بالعربية والإنجليزية
• 📦 دعم 12+ مدير حزم: APT, DNF, YUM, Pacman, Zypper, Eopkg, XBPS, Emerge, PKG, APK, Nix
• 📱 تكامل مع Flatpak و Snap: إدارة شاملة لجميع أنواع الحزم
• ⚙️ أدوات نظام متكاملة: نسخ احتياطي، صيانة، معلومات النظام
• 🎨 واجهة ملونة: تجربة مستخدم جذابة وسهلة الاستخدام

🔧 كيف يعمل؟

الهيكل التقني

يستخدم GT-CLPM آلية ذكية للكشف التلقائي عن مدير الحزم المناسب لنظامك، ثم يقوم بتوجيه الأوامر إلى المدير الأصلي مع تقديم واجهة موحدة.

# مثال على الكود الذي يكشف مدير الحزم
detect_package_manager() {
    if command -v apt &> /dev/null; then
        echo "apt"
    elif command -v dnf &> /dev/null; then
        echo "dnf"
    # ... وهكذا لبقية المديرين
    fi
}

الوظائف الأساسية

1. إدارة الحزم التقليدية: تثبيت، إزالة، تحديث، ترقية
2. البحث والمعلومات: البحث في المستودعات، عرض معلومات الحزم
3. الصيانة: إصلاح الحزم المعطلة، تنظيف الذاكرة المؤقتة
4. النسخ الاحتياطي: حفظ واستعادة قائمة الحزم المثبتة

🚀 طريقة الاستخدام

التثبيت السهل

# التثبيت برمزة واحدة
curl -fsSL https://raw.githubusercontent.com/SalehGNUTUX/GT-CLPM/main/install.sh | bash

التشغيل

gt-clpm

الواجهة التفاعلية

عند تشغيل البرنامج، تظهر قائمة رئيسية منظمة:

🏠 القائمة الرئيسية
1. 📦 عمليات مدير الحزم
2. 📱 مدير فلاتباك

Server monitoring 101

I have been running a @yunohost server for ~5 years now, but there is one question I have never been able to answer: how loaded is my server? 👀

I know, I am a terrible sysad (actually, I am not a sysad, at all), because I have no idea how to determine:

• if my server is running smoothly
• if the server is under stress, and why
• what applications are the heaviest
• if there is the possibility of installing more apps
• when peaks of stress are happening and what is causing them

In general, I would like to understand the fundamentals of server monitoring: what are the most critical metrics and what do they mean? What parameters do I have to keep an eye on?

I installed Prometheus and Grafana, but then I realized I have absolutely no idea what to do next… Do you have any suggestions?

I thought about watching some video tutorials, but I would not really know how they would relate to YunoHost installations.

Please, if possible reply in this thread of the YunoHost forum, so that we can keep track of this useful information also for others in the future. 🌻

Once I will have learned the basics, I would be very happy to write some pointers about this in the documentation, or an essential YunoHost Monitoring tutorial.
