I changed the config to "server-media" as name for the export and did a 'sudo systemctl restart nbd-server.service' on the server and then I connected from the client via 'sudo nbd-client -name "server-media" shi /dev/nbd1': Jan 19 11:05:55 shi nbd-server[20236]: Stopping Network Block Device server: nbd-server. Jan 19 11:05:55 shi nbd-server[20239]: nbd-server. Jan 19 11:06:13 shi nbd_server[20241]: Spawned a child process Jan 19 11:06:13 shi nbd_server[20257]: Connection not allowed (unknown by parent?!?) Jan 19 11:06:13 shi nbd_server[20257]: Modern initial negotiation failed Jan 19 11:06:13 shi nbd_server[20241]: Child exited with 1 Then I changed the name of the export back to "shi-media", did the same to restart and connected from the client to shi-media: Jan 19 11:08:16 shi nbd-server[20597]: Stopping Network Block Device server: nbd-server.

HTH and thanks for looking into this. ATM I'm hearing music thanks to your nbd related efforts. Regards, Gregor
