[ibr-dtn] (dtnping) WARNING : TCPConnection & WARNING BundleCore

Hello,

I'm trying to do a "dtnping" between two dtn nodes (node1 and node2).

from node 2 : dtnping dtn://node1/echo

I have noticed that they can see each other, however, when I try to make a ping from node2 to node 1, I get this warning : *WARNING: bundle rejected: bundle has expired **([415720186.377] dtn://node2.dtn/zsKZSPktexxyNvJ dtn://node2.dtn/zsKZSPktexxyNvJ -> dtn://node1.dtn/echo dtn://nodeC.dtn/echo) **WARNING: bundle has been rejected: bundle is **expired

*I cannot understand the reason. Someone have an idea how may I resolve it?

Thanks!

Best Regards,

Farouk
