Hallo, please note, I am looking for a solution to build a out-of-the-box dtn with raspberry pies. The Goal is a runnig system with three notes (two pie stations and one mobile pie) with a step by step tutorial and ready to use downloads for the sd-cards including mimimum an e-mail-communication. An easy-to-use-out-of-the-box-set would be a good integration in mesh-networks like freifunk or for underdeveloped regions without constant internet-connection. If you have any solutions, ideas or sources please let me know. I take all informations about dtn. running soultions or projects, what i can get. Björn Stoffers

Hello Mehrdad, please reply to the list, so that the discussion can be found by others also. Depending on the type of installation it may not be enough to kill the service. Systemd recognizes it and restarts the service on its own. Please make sure that dtnd is not running after all (ps aux | grep dtnd). We have successfully run IBR-DTN in several different VM types in the past. Passing through a physical network interface was never a problem. - Björn On 25.11.19 12:14, asadii.mehrdad(a)gmail.com wrote: > Hello, > Yes I have installed it from repo, > I also tried to kill the deamon and rerun deamon but still the same error happens. > Do you have any previous experience if running linux on vm and using external wifi adapters cause this type of problems?
