When you log in as otsmanager, you will see instructions like this:

 1===================   TFS commands   ===================
 2 If you run TFS with the following commands, it will auto restart.
 3  Enable auto-start on boot:  sudo systemctl enable tfs
 4 Disable auto-start on boot:  sudo systemctl disable tfs
 5                  Start TFS:  sudo systemctl start tfs
 6                   Stop TFS:  sudo systemctl stop tfs
 7                Restart TFS:  sudo systemctl restart tfs
 8        Check status of TFS:  systemctl status tfs
 9          Show full TFS log:  journalctl -u tfs (q to exit)
10         Follow TFS console:  journalctl -u tfs -f (CTRL+C to stop)
11
12===================  Useful commands   ===================
13Update TFS to latest master:  updatetfs
14      Show service due date:  duedate
15             Show server IP:  serverip
16               Share a file:  transfer path/to/file

Initially, when your service is freshly installed, TFS is not running. It is also not set up to launch on boot.

It is highly recommended that you enable start on boot so that your TFS launches automatically if your machine reboots!

If you use our commands which launch TFS (or any other engine) as a service, it will automatically restart if the process crashes.

Therefore, you should first enable tfs (sudo systemctl enable tfs):

 1otsmanager@176-31-89-137:~$ sudo systemctl enable tfs
 2Created symlink from /etc/systemd/system/default.target.wants/tfs.service to /etc/systemd/system/tfs.service.

Then you can start tfs (sudo systemctl start tfs):

 1otsmanager@176-31-89-137:~$ sudo systemctl start tfs
 2otsmanager@176-31-89-137:~$ sudo systemctl status tfs
