Reflector.service fails to start automatically after reboot.

Zibi1981 · 2023-11-28 20:58:30

For an obscure to me reason reflector.service fails to start automatically after I boot into Arch, but I can start it manually without any issues.

Here's what I see after reboot

$ systemctl --failed
  UNIT              LOAD   ACTIVE SUB    DESCRIPTION

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

I based the configuration of reflector.service on it

$ systemctl is-enabled NetworkManager-wait-online.service
enabled

$ systemctl is-enabled systemd-networkd.service
disabled

Likewise useless by default, https://wiki.archlinux.org/title/Networ … ait-online
Removing the "-s" will break the service for static leases.

Zibi1981 · 2023-11-30 20:17:12

So, if I get you right, regardless of the configuration, automation won't work for reflector.service?

seth · 2023-11-30 20:32:17

The "network-online.target" won't do by default what any sane human would ever expect - regardless in what context.
You can alter the behavior of the NetworkManager-wait-online.service itr, w/ the known caveats.

If that's undesireable, you could just "ExecStartPre=sleep 60" to unconditioanlly wait 60s before reflector actually runs.
Or sth. like

while ! ping -qc1 google.com > /dev/null; do sleep 1; done

In which part of the /etc/systemd/system/multi-user.target.wants/reflector.service should I add this entry?

seth · 2023-12-01 22:25:45

ExecStartPre - I'm at hand not sure whether it'll use a system call to execute this (ie. you can use shell logics) but you could wrap it in an executable "wait_for_interwebz.sh" or "bash -c '…'" it.

Maybe there should™ be a systemd service that actually provides this for an "internet-ready.target"…

Are the "Incorrect system calls (core dumps)" due to the script trying to and failing to connect/ping, but eventually succeeding, or is it pinging endlessly?

single and double quotes have different features.
Seriously, just put that into a script

/usr/local/bin/wait_for_interwebz.sh

#!/bin/bash
while ! ping -qc1 google.com > /dev/null; do sleep 1; done

chmod +x /usr/local/bin/wait_for_interwebz.sh

ExecStartPre=/usr/local/bin/wait_for_interwebz.sh

I see your point, but the external script works the same way as putting it inside the Reflector's config file

"Błędne wywołanie systemowe" is apparently a SIGPIPE ?

while ! ping -qc1 google.com; do sleep 1; done

"Błędne wywołanie systemowe" (Polish) = "Invalid system call" (English).
I'm not sure what a SIGPIPE is, I'm not a programmer.

$ while ! ping -qc1 google.com; do sleep 1; done
PING google.com (142.250.186.110) 56(84) bytes of data.

I googled the polish token and it showed up in relation to https://en.wikipedia.org/wiki/Signal_(IPC)#SIGPIPE - which doesn't make a lot of sense, but whatever.

The plan was to use the unredirected call in the systemd service, systemd might exit w/ that but there's also the default of https://www.freedesktop.org/software/sy … reSIGPIPE=

This might be down to all the ridiculous hardening stuff in the service.

I don't have the slightest idea what are you writing about when it comes do SIGPIPE, but when I consider to make the reflector.service unconditionally wait for 60 seconds before running I have one doubt: quite often my Arch (which I dual boot beside Windows 11) has some issues to connect to my 6GHz WiFi and it could take more than 60 seconds. Quite often I have to turn on and off the WiFi switch for more than once to make it see this WiFi.

If you
1. remove the > /dev/null for the ExecStartPre script
2. Explicitly add "IgnoreSIGPIPE=true" to the service
3. start the service only when you've established an internet connection

Do you still get any errors?
Do you still get errors when starting the service w/ the boot?
Does reflector itself still error or does it wait until you got an internet connection.

As a third alternative, you understood that you can change the NM wait-online service in a way such that it only fires when you actually have an internet connection?
https://bbs.archlinux.org/viewtopic.php … 2#p2134412
If you don't use static leases, the caveat becomes irrelevant.

Zibi1981 · 2023-12-06 22:18:37

For now the "sleep=60" thing seems to make its job. I've read the wiki about modifying NetworkManager-wait-online.service and there are issues with it as well.

seth · 2023-12-07 07:54:32

If you want to re-explore the ping test and there're remaining issues a subshell

(while ! ping -qc1 google.com > /dev/null; do sleep 1; done; true) > /dev/null

might help you out.

I'd been using a "ping" ExecPre= on most of my network-reliant services quite successfully. With reflector, on the other hand, ping uniformly dumped core.

The solution I found is to add a line

SystemCallFilter=capset setuid

below the line

SystemCallFilter=~@resources @privileged

in the reflector service file. This restores capabilities ping needs to operate.
