(recommended method):
Create a file inside the folder /etc/systemd/system named passerverd.service
with a content like this
[Unit] Description=GiD password server: floating password for GiD and problemtypes Requires=network.target After=systemd-user-sessions.service StartLimitIntervalSec=0 [Service] Type=simple ExecStart=/usr/local/passerver/passerverd -port 7073 Restart=always RestartSec=1 [Install] WantedBy=multi-user.target
And to enable it during startup run once
sudo systemctl enable passerverd.service
then the service can be started/stopped with
sudo systemctl start passerverd.service sudo systemctl stop passerverd.service
