From time to time, I use nmap -sP 10.0.0.1-254 to check how many IP devices are online in my home network. There are now more than 50, half of them Raspberry Pis. The need for a central syslog server is slowly growing. An old miniature PC with an Intel Atom, which I retrofitted with an SSD, is the designated candidate for this permanent task. The syslog server comes courtesy of the standard rsyslogd. In its configuration file (/etc/rsyslog.conf), the following lines ensure that the server can receive syslog data from other hosts via UDP and TCP:
$ModLoad imudp $UDPServerRun 514 $ModLoad imtcp $InputTCPServerRun 514
On the other machines, I added an entry of *.* @10.0.0.254 to rsyslog.conf so that they all send their log data to the server on 10.0.0.254.
