I'm sorry when i checked the message again. it say "Could not create a temporary file" in the node A when i try to ping from node A to node C and then when i try to ping node B to node A it say different but similar message "could not create a temporary name" what does its mean? does it related to the storage path defined? hello Johanes, > thank you for replying my question. > > I'm sorry "Could not create a temporary file" is the right message. > I wrote it wrongly. > what's is the meaning of this message and how to solve it ? > > > > Am 28.05.2014 15:32, schrieb magda lena: >> > what() : could not create a temporary name >> >> Is that the correct error message? >> Or say it "Could not create a temporary file" instead? >> > > thank you :) > >

I think you should use dtn://nodeC.dtn/* for the regular expression to match. > 2. how about ibrdtnd.conf for node B and C, what can i configure? at node B, you can leave routing=default and routing_forwarding = yes, if you want node c to answer via node b (i.e. ping reply), then you have to add route1 = dtn://nodeA.dtn/* dtn://nodeB and also routing=none. (beware, node names are case sensitive!) > 3. i start ibrdtn using "dtnd -i wlan0", how can i start it with -v, > can you give me an example ? sure. dtnd -i wlan0 -c /path/to/config -v Btw, it is always the best to send the answer to the mailing list because others might have other ideas, too ;) So I added the list to CC.
