Only using IPv4 for dgram:udp
by Timo Wischer 06 Nov '15

06 Nov '15

Hi guys, I am looking for a way to run the dgram:udp cl only for IPv4. I want to test the throughput of IBR-DTN on an Raspberry Pi over IPv4, because I want to compare this implementation with my implementation. I have tried the following: Removed the IPv6 address from the discovery configuration discovery_address = 224.0.0.142 # ff02::142 But the bundles will send over IPv6 anyway. Switch off IPv6 support with $ echo 1 > /proc/sys/net/ipv6/conf/all/disable_ipv6 But then I get the following error message: Wed Oct 28 16:20:26 2015 ERROR ApiServer: Cannot bind to socket with address [::1]:4550 And no dtn application can connect to the daemon. If have seen that the multicast addresses are hard wired in https://github.com/ibrdtn/ibrdtn/blob/master/ibrdtn/daemon/src/net/UDPDatag… Is there a possibility for only using IPv4 without recompiling IBR-DTN? Best regards, Timo

Patch: dtnping
by Kevin Baron 06 Nov '15

06 Nov '15

To whom it might concern, while I was playing around with dtnping I found out, that you are not able to close dtnping in case you called it with the option --nowait. Neither helped CTRL+C nor a kill command. I looked at the code for the case without --nowait, and found a helping piece for the --nowait case. Now you are able to interrupt dtnping even if you called it with --nowait. Hope my solution, which is in the attachment, is okay. With best regards, Kevin Baron

Patch: dtninbox
by Kevin Baron 06 Nov '15

06 Nov '15

To whom it might concern, don't really know how to contribute with a little patch so I used the git option to implement patches to a mailing list. As I already mentioned there is a little bug in the function dtninbox with the option --quiet. It wasn't working. I fixed this and now everything should work as intended. The patch is in the attachment. Best regards, Kevin Baron

Patch: dtnconvert
by Kevin Baron 06 Nov '15

06 Nov '15

To whom it might concern, again I contribute a little patch to the IBR-DTN this time concerning dtnconvert. In case you called it with -h the help was printed twice. With this patch implemented the help should only get printed once. See the attachment for the patch. Best regards, Kevin Baron

Question: Bundle version and --workdir option
by Kevin Baron 06 Nov '15

06 Nov '15

To whom it might concern, I have two little questions and hope you can help me. My first question is about bundle versions. If I start the daemon with -d 10 and check the messages I found DEBUG.10 BinaryStreamClient: Bundle version differ from ours. DEBUG.10 BinaryStreamClient: unexpected API error! Conditional has been unblocked in the case of receiving bundles from dtnsend or the last ping of a series of pings. I checked the version in Serializer.cpp and saw that it is, despite of the last bundle, always 6 (as it is defined in dtn::data::BUNDLE_VERSION) and at the last bundle only 0. The stream _stream.get(version); isn't reading any version from the bundle, the version stays 0. Is it intended to be so? If yes why is it the way it is? My second question refers to the option -w|--workdir in the function dtninbox and dtnoutbox. I don't really understand how this is intended to work. Can someone explain me what I can accomplish with this feature? Thank you in advance. Best regards, Kevin Baron
