For #NixOS Unstable users:

We're about to stop shipping VPN plugins by default with #networkmanager.

This means you'll need to explicitly configure the ones you need via `networking.networkmanager.plugins`.

In fact, if you are relying on a VPN via #NetworkManager go and do that now to prevent any interruptions.

See this post for further details:

Wenn wer Ärger mit dem #NetworkManager im #AccessPoint Mode hat oder #DHCP, #DNS upstream, DNS port usw. individuell einstellen will...
...ich kann jetzt qualifiziert helfen...

Kein Witz - ich habe sowohl im NetworkManager als auch #dnsmasq jede verfluchte Zeile im Code gelesen und verstanden die das Zusammenspiel beider Dienste im AP-Mode betrifft...

Sysadmin journal: setting up wireguard on all of my Linux desktops

I had to hack together a few things to use wireguard transparently on my Android phone and all of my Linux laptops and desktop.

#Linux Weekly Roundup for March 2nd, 2025: #NVIDIA 570 graphics driver hits stable, #NetworkManager 1.52 addsIPvlan interface support, #Armbian 25.2 ships Linux kernel 6.12 LTS, #FrameworkDesktop, #FrameworkLaptop 12, #LibreOffice 25.2.1 fixes 77 bugs, #KDE Plasma 6.3.2, #LinuxMint's revamped #Cinnamon app menu, and more https://9to5linux.com/9to5linux-weekly-roundup-march-2nd-2025

Setup -> I have a #RaspberryPi #RaspberryPiZero2W running #linux #pios #RaspberryPiOS #headless

Aim: I want the pi to always offer a #hotspot #wifihotspot on #boot
based on the command

nmcli device wifi hotspot ssid pizerohotspot password my_password

Is this below a bad solution ?? -> I came up with this solution in the link below using a .service but fear it shows I am clueless? Is there a better way? Thanks!

#NetworkManager 1.52 Released with IPvlan Interface Support, ethtool FEC Mode, and Much More https://9to5linux.com/networkmanager-1-52-released-with-ipvlan-interface-support-ethtool-fec-mode

#TIL you'll need to set
`nmcli con mod <SSID> wifi.powersave disable`
for your headless pi that it doesn't lose wifi connectivity on idle.

Why is this not in the docs?

If it was a true #opensource project, I'd put up a pull request...

Hmpf. Ich hätte gedacht, dass es leichter ist, einen #RaspberryPi ins #WLAN zu bekommen.

raspi-config macht gefühlt gar nix.

Der #NetworkManager fragt immer wieder nach dem Passwort, das er schon kennt und auch vorschlägt.

#wpa_supplicant scheint einerseits mit dem NetworkManager zusammenzuarbeiten, hat aber auch eigene Konfig.

Und der Kernel schmeisst teilweise Fehler, dass er schon auf unterster Ebene den RF-Channel nicht konfigurieren könne... zumindest lese ich das da raus. Google findet zu der Meldung auch nix hilfreiches. Dann hilft auch nur noch ein Reboot, ansonsten spammt er mir die Logs zu.

Die Doku im Netz geht wild durcheinander und ist meistens undatiert, so dass nicht immer sofort ersichtlich ist, auf welche Generation der Reinen Lehre sie sich gerade bezieht.

Sieht so aus, als wenn ich mich erst einmal tiefer einlesen muss, wie all die Komponenten ineinandergreifen und welche zusammen und welche gegeneinander arbeiten.

So I recently used a #sledgehammer where a #scalpel was needed.

I've got an #HP DL80 Gen9 with the iLO license, but without the #FlexibleLOM card... so to access the iLO I have to have an ethernet cable plugged into the first ethernet port.

Problem is, no matter what I tried in #Webmin or #NetworkManager, every reboot would re-enable that port... which would then get a IP via DHCP (even when I'd disabled it in nm...), which would mean #Zabbix would pick it up as a client and add it.. meaning every time a disk got a little "backed up", I'd get two alerts, and this machine has 12 very old SATA drives in it.

Tired of messing with the damned thing, I finally got out the sledgehammer....
....and blacklisted HP's #OUI from the #DHCP server.

No IP, no extra client created in Zabbix, and only the normally-annoying amount of alerts.

I'll #fsck with it for real, later...

Managing IPv4 Address Conflict Detection with NetworkManager

https://fedoramagazine.org/managing-ipv4-address-conflict-detection-with-networkmanager/

I am really confused why my #NetworkManager nm-applet uses these barely visible icons (first picture) instead of icons provided by upstream (second picture). Anyone having the same issue on #Fedora ?

I suppose it's never too late to discover that #NetworkManager's “IPv6: disable” setting leaves accept_ra = 1 meaning you can still get a scope global IPv6 via your ISP's box, while “IPv6: link-local only” actually does what it says on the box (and indeed, accept_ra = 0).

Hm ich habe hier ein #Debian bei dem der #Networkmanager plötzlich denkt, dass das WLAN "not managed" ist. Das ging Jahrelang bei dieser Kiste. hardware ist in Ordnung manuelles config klappt. Was kann denn da passiert sein?

Hmm, I wonder how much data Ubuntu is mining from connectivity-check.ubuntu.com Are they selling that to someone? #privacy #linux #ubuntu #networkmanager
