In our case no dns/access via firewall was possible to multiple timouts/net traffic generated which was stopping other clients connecting reliably. Edited the input to "connection_host" to "none", restarted splunk and all was well with no further connection timeouts in splunkd.log etc. ... View more

Simple question is do the splunk inputs dedicated to universal forwarders need configuration regarding DNS? I thought that the hostname was provided by the splunk forwarder config files rather than DNS. Am I confusing other inputs with which need this? Any advice gratefully received. ... View more
