6 This is some kind of too slow link. Offline delivery methods is the only
7 choice. Just send files as shown in previous section, but use removable
8 media for transferring packets to other nodes.
10 Assume that you send two files to @emph{bob} node. Insert USB storage
11 device (SD is preferable!), mount it and run @command{@ref{nncp-xfer}}:
14 $ nncp-xfer -node bob /media/usbstick
17 to copy all outbound packets related to @emph{bob}. Use @option{-mkdir}
18 option to create related directory on USB/SD storage if they are missing
19 (for example when running for the first time).
21 If you use single storage device to transfer data both to @emph{bob} and
22 @emph{alice}, then just omit @option{-node} option to copy all available
26 $ nncp-xfer /media/usbstick
29 Unmount it and transfer storage to Bob and Alice. When they will insert
30 it in their computers, they will use exactly the same command:
33 $ nncp-xfer /media/usbstick
36 to find all packets related to their node and copy them locally for
37 further processing. @command{@ref{nncp-xfer}} is the only command used with
40 You can also optionally wait for explicit packets receipt
41 acknowledgement as described in @command{@ref{nncp-ack}}.
