[SOLVED] Issues with rTorrent and systemd

Hello all,

I am trying to run rTorrent as a service that will startup with the system, and restart if an error occurs.
I have followed the instructions here: https://wiki.archlinux.org/index.php/RT … _or_screen

I tried with both tmux and screen but i am getting similar errors on each:

systemctl start rt@$USER

Job for rt@root.service failed. See 'systemctl status rt@root.service' and 'journalctl -xn' for details.

systemctl status -l rt@root.service

Re: [SOLVED] Issues with rTorrent and systemd

Is your user really called root, and does /home/root/ exist?

updating the user in the service file worked. Thanks!

Re: [SOLVED] Issues with rTorrent and systemd

FYI running rtorrent as root is the height of madness.

Re: [SOLVED] Issues with rTorrent and systemd

I'm experiencing similar problem. But in my case I don't want to run it as root but as regular user.

journalctl

Update: my rt service started after restart. But anyway it would be good to know how to fix my configuration to avoid such problems in future.

Re: [SOLVED] Issues with rTorrent and systemd

I think that the service should wait when the user has logged in.

Re: [SOLVED] Issues with rTorrent and systemd

I'm not sure as I also couldn't start this service being already logged in. I had to restart my machine.

Re: [SOLVED] Issues with rTorrent and systemd

Rebooting was not that much necessary.

# systemctl daemon-reload

could suffice

Thx for the hint! Is should be useful as I still have some issues starting rTorrent - sometimes the service starts sometimes not. For me it shouldn't be marked as solved

systemd does not have a way of knowing when the rtorrent process exits. systemd treats the service as stopped right after its ExecStop= exits, but rtorrent may need additional 3-5 seconds to shutdown. When the entire system shuts down in 2 seconds, then the rtorrent process is killed with rtorrent.lock file left on the filesystem. This will cause the rt.service to fail on the next boot.

Quick fix

journalctl -u rt@user
