Hi, Thanks for replying my question.

yes, the message "received-bundle queued-bundle expired-bundle deleted" appear instantly in the notice log when the dtnping start

it doesn't say that the bundle refused, just repeating received-queued-expired-deleted message and got timeout for dtnping.

yes, i also check the date/time and it was same for all my machines

i try to add --lifetime parameter and the message still appear(same with before)

on the other side (my raspi) when it dtnping to my ubuntu, it got exactly the same message. but both node can dtnping its local daemon

i want to try enable the timesync but i dont know which one of the time config that i can enable.

Hi,

...

• new bundle queued

• bundle deleted

• bundle has been expired

• bundle received

does the expired message appear instantly? does it say the bundle was refused? if so, check the time/date setting an all machines. you can try to add the parameter --lifetime 7200 or so(i think, can't check it right now)...

what about the other side? can you ping your local daemon?

another option is to enable the dtn timesync in the config, but johannes/the documentation knows better about this...

regards, Stephan
