the good old syslog daemon

warning for gnu/linux

there has been some attempt to have sysklogd on debian in the past – but you need to build yourself as for 2024 – see sysklogd

otherwise as for 2024 there is GNU’s implementation as package

    apt install inetutils-syslogd

    #cd /etc/
    #cp -pi syslog.conf syslog.conf.dist
    #vi syslog.conf

systemctl restart inetutils-syslogd.service
systemctl status inetutils-syslogd.service # generated
find /etc/rc*.d/ | grep syslog
