there has been some attempt to have sysklogd on debian in the past – but you need to build yourself as for 2024
otherwise there is GNU’s implementation as package
apt install inetutils-syslogd
cd /etc/ mv -i syslog.conf syslog.conf.dist grep -vE '^#|^$' syslog.conf.dist > syslog.conf.clean grep -vE '^#|^$' syslog.conf.dist > syslog.conf
systemctl restart inetutils-syslogd.service systemctl status inetutils-syslogd.service find /etc/rc*.d/ | grep syslog
