Diode Receiver Add-On

This Add-On works together with the Diode Sender Add-On (https://splunkbase.splunk.com/app/4263/)

It is designed to send data between Splunk servers that can pass through a data diode, while preserving the Splunk metadata.

The sender will encapsulate Splunk metadata like sourcetype, source, host, _time into the _raw message which can then be forwarded over syslog via UDP or TCP. The receiver will unpack this and populate the metadata fields as well and restore the _raw to its original state.

Create a local/inputs.conf and enable either TCP or UDP:
The ports can be changed as long as they match the sender Add-On.

# Listen on a TCP port to receive syslog traffic from the diode
# Configure incoming TCP syslog to not append a timestamp or hostname.
# TCP does not strip the priority byte by default.
disabled = 0
sourcetype = diode-syslog

# Listen on a UDP port to receive syslog traffic from the diode
# Configure incoming UDP syslog to not append a timestamp or hostname.
# UDP strips the priority byte by default. Keep it to be consistent with TCP.
disabled = 0
no_appending_timestamp = true
no_priority_stripping = true
sourcetype = diode-syslog
