Manipulating operating system services

To be able to start, stop and restart the operating system services, you must use the command orbit service.

mt4adm@vmdf-giskard:~$ sudo orbit service --help
Usage: orbit service <service> <command>

Send commands to the systemd manager

Arguments:
  <service>    The service name
  <command>    Systemd command: [start|stop|restart|status]

Flags:
  --help     Show context-sensitive help.

  --force    Force the command execution, never prompt
  --show

As an example, let's see the status of the SNMP service.

mt4adm@vmdf-giskard:~$ sudo orbit service snmpd status
● snmpd.service - Simple Network Management Protocol (SNMP) Daemon.
   Loaded: loaded (/lib/systemd/system/snmpd.service; enabled; vendor
           preset: enabled)
   Active: active (running) since Fri 2020-06-12 21:18:21 CEST; 41min ago
  Process: 11119 ExecStartPre=/bin/mkdir -p /var/run/agentx (code=exited,
           status=0/SUCCESS)
 Main PID: 11120 (snmpd)
    Tasks: 1 (limit: 3489)
   Memory: 7.7M
   CGroup: /system.slice/snmpd.service
           └─11120 /usr/sbin/snmpd -Lsd -Lf /dev/null -u Debian-snmp -g
             Debian-snmp -I -smux mteTrigger mteTriggerConf -f -p /run/snmpd.pid

To restart a service, just use the command restart. The same syntax as in the example can be used for the commands start and stop, which will start and stop services, respectively.

mt4adm@vmdf-giskard:~$ sudo orbit service snmpd restart
