Dear Sebastian,
Thank you very much,
The problem already solve, I change the Api interface to Any, before I use Api interface = wlan0 because I use ad-hoc for my mesh network. So I think this item make the problem occur.
Thank's very much

Hi,
This implies, that the daemon on A is running, but was unable to bind the API port. (Because the dtn tools are also using a TCP port to communicate with a locally installed daemon). You can check whether IBR-DTN is bound to the API port (usually 4550) by using
netstat -lnp
(assuming you are using linux). It should be bound to a loopback interface.
Also, when the daemon is starting, you should get a message that the API has been bound to the correct interface.
For reference, on a correctly configured system it might look like this for netstat -lnp
tcp 0 0 127.0.0.1:4550 0.0.0.0:* LISTEN 7085/dtnd
You will find other lines with port 4556 for every interface where a TCP convergence layer is used and udp port 4551 if discovery is enabled.
The startup of the daemeon should look similar to this:
Sat Dec 20 21:15:37 2014 INFO NativeDaemon: IBR-DTN daemon 0.13.0-414 (build 63c8a50) Sat Dec 20 21:15:37 2014 INFO Configuration: Configuration: /tmp/ibrdtn.config Sat Dec 20 21:15:37 2014 INFO BundleCore: Local node name: dtn://sbase.dtn Sat Dec 20 21:15:37 2014 INFO BundleCore: Lifetime limited to 1209600 seconds Sat Dec 20 21:15:37 2014 INFO BundleCore: Pre-dated timestamp limited to 604800 seconds in the future Sat Dec 20 21:15:37 2014 INFO BundleCore: Forwarding of bundles enabled.

I guess this failed in your case
Sat Dec 20 21:15:37 2014 INFO NativeDaemon: TCP ConvergenceLayer added on eth0:4556 Sat Dec 20 21:15:37 2014 INFO NativeDaemon: TCP ConvergenceLayer added on br-lan:4556 ^^This tells that TCP convergence layers are bound to the two listed interfaces. I guess this worked on your host A, which explains why it can answer to pings
