I am pleased to announce NNCP 7.1.0 release availability!
NNCP (Node to Node copy) is a collection of utilities simplifying
secure store-and-forward files and mail exchanging.
This utilities are intended to help build up small size (dozens of
nodes) ad-hoc friend-to-friend (F2F) statically routed darknet
delay-tolerant networks for fire-and-forget secure reliable files, file
requests, Internet mail and commands transmission. All packets are
integrity checked, end-to-end encrypted (E2EE), explicitly authenticated
by known participants public keys. Onion encryption is applied to
relayed packets. Each node acts both as a client and server, can use
push and poll behaviour model. Also there is multicasting areas support.
Out-of-box offline sneakernet/floppynet, dead drops, sequential and
append-only CD-ROM/tape storages, air-gapped computers support. But
online TCP daemon with full-duplex resumable data transmission exists.
------------------------ >8 ------------------------
The main improvements for that release are:
* Multicasting areas feature appeared. Implemented merely by an
additional plain packet type with "nncp-toss", "nncp-file" and
"nncp-exec" commands modification.
http://www.nncpgo.org/Release-7_005f1_005f0.html
* Fixed workability of "nncp-file" and "nncp-exec" commands, that use
temporary file (stdin and "-use-tmp").
* Fixed disappearing bad return code in "nncp-exec" command.
* Fixed invalid ".hdr" generation when transitional packets are used.
* "-all" option appeared in "nncp-rm" command, applying to all the
nodes at once.
* "-cycle" option appeared in "nncp-check" command, looping the check
in infinite cycle.
* "nncp-rm" command can take node alias name.
* "nncp-pkt" can parse ".hdr" files.

Hi Sergey,
Wow, there's a lot exciting in here!
The stdin looks better - thanks!
I've got a weird nncp-toss issue now, when dealing with received
files.
It looks like this:
Jul 5 15:48:19 datavac nncp-toss[4041]: 2021-07-05T20:48:19Z Got
file hi (3 B) from alexandria
Jul 5 15:48:19 datavac nncp-toss[4041]: 2021-07-05T20:48:19Z
ERROR Tossing file
alexandria/ZEQV4GZMI2NZJJ5RSJTV245C35UZ3BT4K2I4VXOTTGP62XKFSISA (3
B): ZEQV4GZMI2NZJJ5RSJTV245C35UZ3BT4K2I4VXOTTGP62XKFSISA:
dirsyncing: open
ZEQV4GZMI2NZJJ5RSJTV245C35UZ3BT4K2I4VXOTTGP62XKFSISA: no such file
or directory
Now, nncp-toss here is being run from systemd like so:
/usr/local/nncp/bin/nncp-toss -noprogress -cycle 30 -seen
If I leave off -seen, then it tosses properly. (This also goes
for running directly from the command line).
Something about -seen is causing it to break here.
It does actually deliver the file... but it does it again and
again, on every toss, due to that error.
Thanks,
- John

I spoke too soon on the stdin.
It appears to be truncating certain small files. I am wrapping
everything in gpg, and it is detecting truncation during
verification (or the decrypted data is truncated). This is with
nncp-file -
Thanks again,
John

Some more detail on this:
The files were about 700-950 bytes in length.
It happened in quick succession on one machine. If you have
trouble duplicating, I will try to set up a test installation and
see if I can whip up a demo case.
What's odd is that it corrupted about 5 out of 15 files that were
generated at the time -- and they were all small ones. The bigger
ones were fine.

Fixed in 7.1.1. Thanks for the report!
Sorry that that. Really need to make many functional tests.

Currently I can not reproduce that issue locally. I use "nncp-exec -"
analogue for all my email -- have never seen that kind of issues.
I creates a subset of relatively small various files with fio. 1000
files of 100-2000 bytes sizes:
% cat foo.fio
[mein]
readwrite=write
bssplit=100/:500/:1000/:1500/:2000/
nrfiles=1000
filesize=100-2000
Then I passed them through gpg and nncp-file -:
for i (mein.0.*) gpg -r offline -e < $i | nncp-file - self:$i.gpg
and tossed:
nncp-xfer -mkdir -node self /tmp/self-shared
nncp-xfer -node self /tmp/self-shared
nncp-toss
And then decrypted and checked if all the data is "undamaged":
cd ~/incoming
for i (*.gpg) gpg -d < $i > $i:r
l *~*.gpg | sort | xargs cat | sha1
cd fiodir
l mein.0.* | sort | xargs cat | sha1
And all hashes are matched, no gpg errors.
I looked at the NNCP's code again and currently see nothing like some
kind of unflushed bufio-buffers and that code has not been touched for a
long time. Unfortunately currently I have got no ideas how to reproduce
the problem.

Thank you for 7.1.1! This release is now working perfectly for
me! I am excited to try out the multicast stuff now.
I dug into this some more. I was able to reproduce it, but I now
know why you couldn't. It was, in fact, not actually introducing
corruption but somehow re-delivering files that had been sent a
day or two ago. Why, I have no idea. How, I also have no idea.
Where, I don't know either. But once those got flushed out of the
system, everything was fine. No more dupes so far.
grumble grumble about ZFS's error message "cannot receive: failed
to read from stream". I eventually was able to verify sha256sums
matched, and then turned on zfs receive -v for verbose mode... and
the error was basically attempting to receive a snapshot that was
already present. It was an old nncp-file packet that somehow got
re-delivered and re-processed, and the same went for all the
others also.
I am sorry to have sent you on the wrong chase for that!
- John
