Services list	`# chkconfig –list \| grep ^Charon` There are 2 services that can be installed: `charon_gstart`: guests start/stop `charon_logchk`: log monitoring	`# systemctl \| grep ^charon` Typically there is: one service for dongle connection/disconnection monitoring (`charon_monusb`) 2 services per guest (virtual machine), one for the emulator itself and one for the log monitoring
Prevent service to start at boot	`# chkconfig <service> off`	`# systemctl disable <service>` It is not recommended to use command line to do so, please use menu option 6
Enable service start at boot	`# chkconfig <service> on`	`# systemctl enable <service>` It is not recommended to use command line to do so, please use menu option 6
Start or Stop service	`# service <service> start` `# service <service> stop` Without supplemental parameter, all guests or logs monitoring are stopped To stop a dedicated guest, add the configuration file name To stop a dedicated log file monitoring, add the log file name Files can be truncated to their name only, directory and extension will be automatically completed Example: `# service charon_gstart stop pluto` `# service charon_gstart stop /opt/charon/cfg/pluto.cfg`	`# systemctl start <service>` `# systemctl stop <service>` Example: `# systemctl start charon_pluto`
Service status	`# service <service> status`	`# systemctl status <service>` Use of the following options is recommended: "`-l --lines=xx`" where "xx" a number of lines from the journal to show, counting the most recent ones.
Service removal	`# chkconfig –del <service>`	First disable the service: `# systemctl disable <service>` then remove (optional) the associated service file: `# rm /etc/systemd/system/<service>.service` Example: `# systemctl disable` `charon_pluto` `# systemctl disable` `charon_logmon_pluto` `# rm /etc/systemd/system/charon_pluto.service` `# rm /etc/systemd/system/``charon_logmon_pluto``.service` It is not recommended to use command line to do so, please use menu option 6
