Hi you all.
By exploring the code I found out that a telnet server is running on localhost:4550. By grep-ing "if(cmd" in the files I found some command could be issued.
However I could send/receive any bundle through this interface.
I'm working on ibr-dtn and I'm in needs, as I already told in a previous mail, of using Java and ibr-dtn.
Instead of working on a specialized JNI/JNA solution or whatever-else I decided to write a telnet server (which will be then usable from Python, Java, C, C++, everything else! But do not want to recreate something which already does exist.
