Hi Stephan,
I have just tried again on a brand new installation and observed something strange, hopefully I have found a fix to the problem. I tried to troubleshoot in stages, this is what I did:
1. Start dtnd with default conf file - Started OK with no convergence layer 2. Add custom conf file (below conf1), but do not specify the correct interface name, also do not start dtnd with -i option - Started OK with UDP Convergence layer (Datagram ConvergenceLayer (UDP) added on eth0:4556) 3. Add custom conf file (below conf2) with correct interface name and use -i option - Fails: (TCP ConvergenceLayer added on eno16777736:4556) 4. Revert back to step 2 - Started OK with UDP Convergence layer (Datagram ConvergenceLayer (UDP) added on eth0:4556) 5. Add custom conf file (below conf2) with correct interface name and _do_not_ use -i dtnd startup option - Works: (Datagram ConvergenceLayer (UDP) added on eno16777736:4556)
I think perhaps the net_eth_interface option in the conf file and the -i dtnd startup option may be conflicting with each other. It appears to start OK using only the net_eth_interface option in the conf file. When I am logged on to my test bed in a few hours I will try some data transfers and report back.
Kind Regards, Nik

Hi Stephan,
Thank you for your kind reply.
I originally tried both net_eth_type = udp & static1_proto = udp, but this didn't work. I will try them both as dgram:udp later and respond back.
Kind Regards, Nik

Hi Nik,
static1_uri = dtn://rx static1_port = 4556 static1_address = 10.0.1.3 static1_proto = udp
Have you tried dgram:udp at this point?
Best regards, Stephan
