[ibr-dtn] WARNING BundleFilter: bundle rejected due to invalid authentication

When using:

*$ dtnping dtn://zed1/echo*

dtnd returns the following error before the echo times out:

*WARNING BundleFilter: bundle rejected due to invalid authenticati**on ([0.233726701] dtn://zed0/aSreNqipcPcrKVmE)*

Where zed0 is the pinging host device.

The setup is two ZedBoards connected via an ethernet switch on the same subnet.

Attached is my ibrdtn.conf file which is identical between the two devices with the only difference being the local node name which is zed0 or zed1.

I tried explicitly setting the

* security_level = 0*

as well to the same effect.

Thanks.
