1. Setup your CHARON virtual machine as a service. To do so, refer to the corresponding documentation or install and use the Charon Linux Toolkit.
   .

2. Edit the service configuration file and add the following parameters:

   Parameter	Type	Description
   Restart	text	Configures whether the service shall be restarted when the service process exits, is killed, or a timeout is reached
   RestartSec	numeric	Configures the time to sleep before restarting a service (as configured with Restart=). Takes a unit-less value in seconds, or a time span value such as "5min 20s". Defaults to 100ms.
   StartLimitInterval	numeric	Configure service start rate limiting. By default, services which are started more than 5 times within 10 seconds are not permitted to start any more times until the 10 second interval ends. With these two options, this rate limiting may be modified. Use StartLimitInterval= to configure the checking interval (defaults to DefaultStartLimitInterval= in manager configuration file, set to 0 to disable any kind of rate limiting). Use StartLimitBurst= to configure how many starts per interval are allowed (defaults to DefaultStartLimitBurst= in manager configuration file).
   StartLimitBurst	numeric

   More parameters can be defined for auto-restart. Please refer to your Linux distribution documentation (see 137077595 further)

   Example: The following service will restart in case of failure (Restart=on-failure) after 30 seconds (RestartSec=30) with a limit of 2 (StartLimitBurst=2) within 10 minutes (StartLimitInterval=600)

   # vim /usr/lib/systemd/system/as4100.service [Unit] Description=DEMO as4100 After=atd.service postfix.service ncu.service aksusbd.service Wants=aksusbd.service   [Service] Type=forking WorkingDirectory=/charon/log ExecStart=/opt/charon/bin/as4100 -d /my_services/as4100-service.cfg ExecStop=/charon/scripts/mystopscript /my_services/as4100-service.cfg Restart=on-failure RestartSec=30 StartLimitInterval=600 StartLimitBurst=2   [Install] WantedBy=multi-user.target Div class commandline

3. Reload systemd manager configuration:

   # systemctl daemon-reload
