Re: [ibr-dtn] [IBR-DTN] " ERROR IPNDAgent: failed "

Hi Matheus,

I'm replying public to the IBR-DTN-list since there are many other people reading and might have an idea, too. Thus, I also attached the files, too.

Can you draw an (ASCII-Art) image of the setup (network interfaces, ...) of what you are trying to do, please?

In the mail you said, you are using wlan0 for communication, but in the config, you defined wlan1 as the device, where you can reach the API. This means, that tools like dtnsend can connect to the deamon via this interface. If I get it right, there are no convergence layers defined in your config, which are needed for communication between the nodes.

How are the Raspberry and BeagleBone connected to each other, via Ethernet or WLAN?

Best regards, Stephan

Thanks for answering! The corresponding configuration file log of the previous email is ibrconf.

I tested again using the default setting when installing the program, the ibrdtnd_default.conf. The corresponding log is ibrdtn_default.log. Attached are also the interfaces settings.

I would like to stress that I am only interested in connecting a Raspberry Pi to others who are running the daemon to measure protocols performances, be a BEAGLEBONE or Raspberry well. Oh yeah, I'm using hostapd Program wlan0 interface. This affects something?

(Code attached).

    can you please attach your configuration file?

    Best regards to Manaus,
