I am pleased to announce NNCP 5.5.0 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.
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:
* Bugfixes in "nncp-call(er)"/"nncp-daemon", "nncp-bundle" and
"nncp-stat".
* "nncp-rm" has "-dryrun" and "-older" options now.
* "nncp-exec" has "-use-tmp" and "-nocompress" options now.
Uncompressed packets are not compatible with previous NNCP
versions.
* "nncp-call", "nncp-caller" and "nncp-daemon" commands have
"-autotoss*" options for running tosser after call is ended.
* Updated dependencies.
* Administration notes section appeared in documentation:

Hi,
I have a build error with this version:
contrib/do install
do install
do bin/all
do bin/nncp-bundle
do gopath
# golang.org/x/term
golang.org/x/term/term_unix_linux.go:9:7: ioctlReadTermios
redeclared in this block
previous declaration at
golang.org/x/term/term_unix_aix.go:9:26
golang.org/x/term/term_unix_linux.go:10:7: ioctlWriteTermios
redeclared in this block
previous declaration at
golang.org/x/term/term_unix_aix.go:10:27
do: nncp-bundle: got exit code 2
I initially tried just removing lines 9 and 10 from
term_unix_linux.go, but then it complained about an unused import.
Removing that plus the
import "golang.org/x/sys/unix"
line lets the build proceed.

Hi Sergey,
Thanks again for the new version. I've been experimenting with
-autotoss.
At first it didn't seem to do anything in nncp-caller, but after
killing the remote nncp-daemon, it went on to do the toss.
I think that waiting for the remote end to hang up might delay
things; I have a very large onlinedeadline and timeout. I think
pseudo code like this might do the trick:
loop forever
needstoss = false
if remote.has_packets_for_us()
needstoss = true
process_packets
when ! remote.has_packets_for_us()
if needstoss
toss
needstoss = false
In other words, every time we transition in state from "remote
host has packets for us" to "remote host no longer has packets for
us", we toss. This could also be very nice even for 10-second
onlinedeadlines, because it might allow a toss and response to be
sent even within that window regularly.
What do you think?
- John

Greetings!

It looks like your Go thinks he is both AIX and Linux. I have copied
golang.org/x/term without any modifications from the upstream. I assume
that you probably have old Go version what does not know anything about
AIX and does not treat "_aix" as a build-tag. As I can see, firstly it
appeared https://github.com/golang/go/commit/bf8e6b70276ddfd3e070964542020fe782c1eec8
at 2018 year.
Currently (in develop branch) NNCP uses golang.org/x/term instead of
golang.org/x/crypto/ssh/terminal, that anyway depends on golang.org/x/term.
So that "term" dependency anyway is there and upstream has knowledge
about AIX. I suggest you to update your Go, that will also bring
performance benefits as a rule. Or just: find . -name \*_aix.go -delete
I have tried Go 1.10 -- the same problem as you have.
I have tried Go 1.11 -- same problem.
I have tried Go 1.12 -- build/test is ok.
So I will update documentation and raise Go's 1.10+ version to 1.12.
I have found some Ubuntu virtual machine image and tested building on
it with the golang-go taken from repository (go1.13.8) -- builds fine.

There is no such kind of states inside, that is why there is just
timeout mechanism based on onlinedeadlines. So there will be always
race: toss may be started, but actually remote side's packet was already
on the wire. Toss will burden the drives, possibly making data transfer
slower.
However the same applies to nncp-toss running in background. I think
that will be relatively easy to run tosser when connection is alive
either after some timeouts after the last packet were received, or just
every second (that has little overhead). I think it will be useful for
not keeping nncp-toss running if no connections are made at all.
So I will add it ((optional) tossing while the connection is online),
but probably not on current week.

Also I think there should be added autotoss option per call in
configuration file. Some kind of that.

Yes, thanks, that's a nice idea!

Yes, Debian stable and Raspbian both ship with 1.11.

That's a good enough workaround, yes.

Understandable, but a bummer; it raises barrier to entry,
especially on Raspberry Pi. On Debian, there is 1.14 in
buster-backports. Raspberry Pi OS / Raspbian doesn't have
backports, though in practice the Debian buster-backports work
there at times. It may be a bit dicey with something like this in
the toolchain, though, because part of why Rasbian exists is
optimizations for its particular architecture that the more
general Debian distro doesn't do.
Previously, one could just apt-get install golang && PREFIX=blah
./contrib/do install
Anyhow, thanks again!

Understand that, but anyway earlier or sooner I will upgrade
dependencies, that are also depend on that updated golang.org/x
libraries with AIX "knowledge" and who knows what other kind of
incompatibilities more.
Actually Go is pretty easy to build. Either you have Go 1.4, or you have
more modern installation and any future version can be built for example
by "cd go/src ; ./all.bash". Also, comparing to something like GCC/LLVM
(which take many hours on my laptop to build), it takes only several
minutes.
