From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Selfhost offline software (lemmy.ml)

Recently in Spain we have suffered a complete power outage, with no electricity for a long time. Some were able to have power on their computers with generators, solar panels, etc. And I know you can have data connectivity with SDR or HAM radio. But my question here is, what are some good self-host/local offline software that we can have and use for when something like this happens. I know kiwix, and some other for manuals. Please feel free to share the ones you know and love, can be for any type of thing as long as it works completely offline, just name it. Of course for GNU/Linux (using Arch myself BTW). Thanks in advance.

I have my homeserver rsync three Arch mirrors and three Arch ARM mirrors in rotation on three days every week. Thus I have full local repos for these. All my machines are configured to use this local repo. The reason I do this is precisely to be prepared for the inevitable 'Internet is broken' scenario.

total respect

Since this has seen some interest – here's how much disk space this opulence costs: Arch x86 repository is 113 Gb and Arch ARM is 123 Gb :)

That’s actually much smaller than I expected.

Yeah, some people don't like to run with full repo mirrors but keep updated copies of the Debian ISO that can be mounted as repositories at any point:

It's essentially the same, but in another format.

One can also use a cache to hold deb and rpm files requested by the machines. (Works great when running hundreds of systems.)

I like "apt-cacher-ng". It will do deb and rpm. https://wiki.debian.org/AptCacherNg

Caches expire, eventually.

[–] [email protected] 1 points 1 hour ago

Apt-cacher-ng doesn't tend to expire automatically. It can be configured to keep the last version regardless. https://www.unix-ag.uni-kl.de/~bloch/acng/html/maint.html#extrakeep
