Thank you all for your input’s !

As I’m not familiar enough with BGP, AS etc…

I think I’ll go for the list generated by
https://github.com/lord-alfred/ipranges
https://github.com/sakib-m/IP-Prefix-List

To start with.

Then I’ll see if it’s possible to gather those IP ranges without relying on third party services…
but that seem unfeasible without be connect to a Internet Exchange Point (IXP) right ?

Thank you all for your input’s ! \

So I have created a table , that I’ll put in my first post.

Feel free to post update like

|brand|model|Price €|GPIO pair|CP|Lan Ports|idle watt|Surface area cm²|Storage ports| WiFi / BT|url|
|Raspberry Pi|Pi 5 B (4GB)|52|12|Quad-core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5GHz.|1x 1GbE|3|47|SD|||

or even without the row header

setfacl -m m:r aFile
#re set the mask

solve the problem, but the question is: why the F**** this is happening !?

Update, this is only happening when I copy files from a ~SMB share… :'(
Otherwise it’s correct…

Thank you all !

Indeed setting execute perm on example, sub1, sub2, static

The program/user have now access to the directory.

In order words all the parents directory need at least execute in order to have access in the targeted directory…

Now I gave 751 for static. Meaning than others (here nginx) cannot list the files within. But never the less it works
the static files are appearing when requested (HTTP) but forbidding nginx to list the directory is changing something ? (performance/security)

Thanks

Thank you all for your quick reactions !!

To summarize if I want to use the PDF built-in signing I will need to convert my OpenPGP into a X.509 cert otherwise I can simply use the OpenPGP file signing

I want to stick to the UNIX Philosophy especially:

Write programs that do one thing and do it well.

So I will use the OpenPGP signing tool :)

Thanks !
