Hi, yes, I am 99% sure Prophet keeps its routing table in RAM, so it would be lost when a node is powered down/a daemon restarted. In case you extend or modify this behavior we always welcome pull request towards our Github project https://github.com/ibrdtn/ibrdtn/ I guess the best option would be an additional configuration option in the routing section, so people can choose whether they want to have a persistent routing table or not.

I think it also stores its variables in RAM memory.

Is the problem, that the nodes do not _discover_ each other (i.e. you do not see "nodeXX available" log messages)? IP-Multicast needs to work for discovery to work. Or is the problem, that the nodes discover each other, but IBR-DTN is unable to establish a TCP connection? If this is the case, can other apps establish a TCP connection (e.g. netcat) ? > > > Sebastian > > > > > > On 2014-04-08 10:11, Romeu Monteiro wrote: > Dear all, > > I have two questions regarding IBR-DTN: > > - If the daemon (or the device where the daemon is running) is turned > off, all the bundles in storage and data from the Prophet routing > algorithm are lost, right?

2 questions on IBR-DTN
by Romeu Monteiro 08 Apr '14

08 Apr '14

Dear all, I have two questions regarding IBR-DTN: - If the daemon (or the device where the daemon is running) is turned off, all the bundles in storage and data from the Prophet routing algorithm are lost, right? Is there anyway to prevent this? We have devices which are sometimes turned off and we would not like them to loose all their information each time that happens. - We are having problems transfering files between devices, and perhaps between different subgroups of IP addresses. In our case, we have 3 devices originally set on the IP addresses: 20.0.5.13/24, 20.0.5.56/24 and 20.0.6.66/24. We changed the network mask (to 16 bits) to allow all the devices to contact each other. With this change, we can ping and even dtnping all the devices with each other. In spite of that, while we are able to send files from 20.0.5.13 to 20.0.5.56, we cannot send them from 20.0.6.66 to 20.0.5.56. It seems we cannot exchange files with the 20.0.6.66 board at all using IBR-DTN. Is there something we should be careful about in this situation? Some kind of network mask situation IBR-DTN cannot handle yet? Thank you, Romeu
