hello, okay i will try it soon and report to you if any error appear

Hi.

You have disabled dynamic routing completely on nodeA. Thus, even direct delivery is not performed in this case. Without any additional static route nodeA does not know how to route bundles for nodeB.

I assume dtnping is working if you ping from nodeA to nodeC, right?

To allow nodeA to ping even nodeB, you need to add an additional route to the configuration of nodeA.

route2 = dtn://nodeB.dtn/* dtn://nodeB.dtn

Alternatively, you can define one route to send all traffic through nodeB.

route1 = dtn://* dtn://nodeB.dtn

Kind regards, Johannes
