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 NativeDaemon: API initialized using tcp socket: loopback:4550
^^This line is important, it tells, that the API port is successfully bound, so that tools such as dtnping/dtnsend etc. can talk to the daemon. 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


MfG

Sebastian
