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

install

debian

    apt install inetutils-syslogd

setup

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