37 Service management with YaST #
YaST provides a service manager for controlling the default system
target, services, displaying service status, and reading the log file. New
in SUSE Linux Enterprise Server 15 SP6 is YaST support for systemd
socket-based
services activation, which configures services to start on demand.
systemd
supports starting services with socket-based activation, for starting
services on demand. These services have two unit types: service and socket.
For example, CUPS is controlled by cups.service
and
cups.socket
. YaST allows you to select the type of
service start-up you want to use.
Figure 37.1, “YaST service manager” shows the options in the Start Mode drop-down box: , , and . Select for socket-based activation. This opens a listening network socket, and the service starts when there is a request.
