The ip route show or ip r s commands will display the routing table on a Linux system. The routing table contains information about how to reach different network destinations. The cat /etc/sysconfig/routes command will display the static routes configuration file, which may not reflect the current routing table. The other commands are either invalid or unrelated to routing. References:https://documentation.suse.com/sles/15-SP3/html/SLES-all/sec-network-routing.html

If you have a service named tftp, the command and options that would enable tftp to start automatically when the server starts are systemctl enable tftp. This command will create symbolic links in the appropriate systemd target directories to enable the tftp service unit. To start the service immediately, you can also use systemctl start tftp or systemctl enable --now tftp.

The configuration files that have a format that is compatible with the system logging facility in SUSE Linux Enterprise are /etc/syslog.conf and /etc/rsyslog.conf. These files contain rules that specify how to filter and process log messages from different sources and destinations. The /etc/syslog.conf file is used by the traditional syslogd daemon, while the /etc/rsyslog.conf file is used by the more advanced rsyslogd daemon. SUSE Linux Enterprise uses rsyslogd by default, but it can also read /etc/syslog.conf for backward compatibility.

The program systemd is the process with process ID 1. It is responsible for initializing the system in the required way. systemd is started directly by the kernel and resists signal 9, which normally terminates processes. All other programs are either started directly by systemd or by one of its child processes.

The system initialization system used in SLES 15 is systemd. It is a modern and powerful system and service manager that replaces the traditional init system. It provides faster boot times, better dependency handling, parallelization, and more features and capabilities.
