Im testing dtnsend and cant seem to send a file with 100 MB. Is it impossible to send it?
Currently, I'm using an Alix3d3 with 256MB RAM and ibrdtn deamon says it can't allocate memory (BinaryStreamClient) for sending a file with 100 MB... where is this memory allocated in the code?

Hi Leonel,
256MB of RAM may not be enough, can you check, what free -m says? You can search for the exact error code in the source code, either using grep on your machine, or -- more convenient -- at github.
Best, Stephan

Thanks Professor. The error message in daemon is:
Wed Apr 12 14:49:24 2017 ERROR BinaryStreamClient: output stream went bad [Cannot allocate memory]; 134217728 of 134482789 bytes copied
Could this problem be solved with fragmentation? How can payload size of fragment be defined in the configuration file in OpenWrt? limit_payload=500K does not seam to work...

In order to get rid of bundles stored in memory you can define the blob_path in the configuration. It should point to a writable folder on a harddrive with twice as much space as the largest bundle you like to send (maybe even some more).
Kind regards, Johannes Morgenroth

Thanks Doctor Morgenroth, I will try that alternative. Could you please explain how can the payload size of fragmentation be configured in OpenWrt?

In order to activate fragmentation you need to set two options in /etc/config/ibrdtn.
config 'daemon' 'main' option fragmentation yes option blocksize 1M

Thanks Dr. Morgenroth. Are the repositories of IBR-DNT in Debian_8.0 folder totaly compatible with Debian 8.7?
