[SOLVED] systemctl instructions unclear

theking2 · 2015-11-21 12:51:19

The instruction in https://wiki.archlinux.org/index.php/Ju … stemd_unit are unclear

After following the steps enabling or starting the service with

systemctl start setmtu@enp2s0.service

A Failed to start error is displayed.

/etc/systemd/system/setmtu@.service
[Unit]
Description=Set mtu on device
Before=network.target

[Service]
Type=oneshot
EnvironmentFile=/etc/conf.d/setmtu
ExecStart=/usr/bin/ip link set dev %i up mtu ${%i}

[Install]
WantedBy=multi-user.target

/etc/conf.d/setmtu
enp1s0=9000
enp2s0=9000

Does the command work in isolation?

Try binding the .sevice to the device:

[Unit]
BindsTo=sys-subsystem-net-devices-%i.device
After=sys-subsystem-net-devices-%i.device

Please post the full error message and the output of:

systemctl status setmtu@enp2s0

`systemctl status setmtu@enp2s0.service` will tell you more, as will `journalctl -u setmtu@enp2s0.service`

Thanks Spider.007 and Head_on_a_Stick

I had put the setmtu@.service file in /etc/systemd/ instead. Moving it to /etc/systemd/system makes it working perfectly.

The instructions are clear. It was my mind that was clouded.

Although what is really confusing is what I find under
https://wiki.archlinux.org/index.php/Ne … eue_length

is the udev method preferable over systemd?
