Standard x86 linux install service will not start on boot

[sadkisson]

I am using this script on a x86 linux install with systemd. I cannot get the script to auto start on boot.

sudo systemctl enable sqm@wan
Created symlink /etc/systemd/system/sys-devices-virtual-net-wan.device.wants/[email protected] → /usr/lib/systemd/system/[email protected].
Unit /usr/lib/systemd/system/[email protected] is added as a dependency to a non-existent unit sys-devices-virtual-net-wan.device.

When I check the status after rebooting:
sudo systemctl status sqm@wan
○ [email protected] - SQM scripts for iface wan
Loaded: loaded (/usr/lib/systemd/system/[email protected]; enabled; preset: disabled)
Active: inactive (dead)

When I start manually after booting the script works:
sudo systemctl start sqm@wan
[email protected] - SQM scripts for iface wan
Loaded: loaded (/usr/lib/systemd/system/[email protected]; enabled; preset: disabled)
Active: active (exited) since Thu 2022-10-20 21:14:19 UTC; 5s ago

Thanks for making this, it works great!

Erm, is your network interface actually called 'wan'? That's usually an openwrt thing...

[sadkisson]

yes, i renamed the interface to wan using systemd link file in /etc/systemd/network

[Match]
MACAddress=xx:xx:xx:xx:xx:xx

[Link]
Description=Ethernet WAN Interface
Name=wan

Hmm, what's the output of: systemctl | grep wan on your system?

[sadkisson]

sudo systemctl | grep wan
sys-devices-pci0000:00-0000:00:1c.0-0000:01:00.0-net-wan.device loaded active plugged 82583V Gigabit Network Connection

sys-subsystem-net-devices-wan.device loaded active plugged 82583V Gigabit Network Connection

[tohojo]

Right, could you try editing the unit file to replace this line: WantedBy=sys-devices-virtual-net-%i.device with WantedBy=sys-subsystem-net-devices-%i.device (disable the unit first, then edit it, then do 'systemctl daemon-reload', then re-enable) and see if that helps?

[sadkisson]

The post above is with the script active after manually start. This is what it looks like on reboot before starting the script.

sudo systemctl | grep wan
sys-devices-pci0000:00-0000:00:1c.0-0000:01:00.0-net-wan.device loaded active plugged 82583V Gigabit Network Connection
sys-subsystem-net-devices-wan.device loaded active plugged 82583V Gigabit Network Connection

I made the change and ran

sudo systemctl enable sqm@wan
Created symlink /etc/systemd/system/sys-subsystem-net-devices-wan.device.wants/[email protected] → /usr/lib/systemd/system/[email protected].
Unit /usr/lib/systemd/system/[email protected] is added as a dependency to a non-existent unit sys-subsystem-net-devices-wan.device.

I rebooted and ran systemctl status sqm@wan:

[sadkisson@router ~]$ sudo systemctl status sqm@wan

That appears to have fixed it! Thank you!
