Logging Modem logs to remote rsyslog server
My FTTH ONU have remote logging option, this allowes me to log to a remote server running rsyslog.
On model, i set IP of my remote server and a UDP port. Default port was 514, i changed it to 511.
Configuring Remote Server
On the server, create file
vi /etc/rsyslog.d/10-remote.conf
Add
$ModLoad imudp $UDPServerRun 511 :fromhost-ip, isequal, "103.35.199.82" /var/log/remote.log & ~
Here “103.35.199.82” is IP address for my router/modem.
Now restart rsyslog
systemctl restart rsyslog
You will be able to see logs at /var/log/remote.log
tail -f /var/log/remote.log
