Hi David,

Thanks for your reply. I'm trying to make dtntunnel transparent for the endpoints by substituting original source and destination addresses and ports. With my modifications one instance of dtntunnel can handle traffic for multiple hosts. When I started to the same for UDP I suddenly discovered that it is unidirectional.

Regards,
Sergey

Hi Sergey,Looks like you are pushing the dtntunnel envelope again:)

I've been using the UDP tunnel as a unidirectional transmitter for a good while but never tried the return path. I experimented this evening and looked at the code a bit. It is definitely only unidirectional at the moment and would take a decent amount of coding to make it bidirectional. 

Sorry, no quick fix,
DZ

PS. I haven't forgotten the TCPTunnel patch and I'll try to get that done this weekend with my home-hobbyist hat on. I was waiting for my other updates to get approved for export but I think they got lost on someone's desk. Those are now 3 patches behind so I'll have to play catch up again once they do get approved.

Subject: [dtn-users] Is dtntunnel in UDP mode unidirectional?

Hello
dtn users,

During my experiments with sending data with nc through dtntunnel, I have found
out that dtntunnel doesn't send data from the nc server to the nc client while
working in UDP mode.

Is my observation correct, or I have misconfigured my system?
