I've configured splunk to receive logs on syslog port 514/udp. I can also see it's listening on that port:
[root@splunk01 ~]# netstat -an
Active Internet connections (servers and established)
Proto Recv-Q Send-Q Local Address Foreign Address State
tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:8089 0.0.0.0:* LISTEN
tcp 0 248 10.22.76.12:22 10.22.20.20:2485 ESTABLISHED
udp 0 0 0.0.0.0:514 0.0.0.0:*
But I see no traffic coming in to the splunk server from the firewall. I find this strange.
The splunkserver has iptables turned off.
In the Astaro FW I've temporarily configured this rule - "any -> syslog -> splunk-server"
What have I missed?
(I have not yet activated the Splunk Enterprise 30-day trial since I'm soon going on vacation.)
