I am pleased to announce NNCP 3.0 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:
* *Incompatible* plain packet format changes. Older versions are not
supported.
* Ability to queue remote command execution, by configuring exec
option in configuration file and using nncp-exec command:
* nncp-mail command is replaced with more flexible nncp-exec.
Instead of "nncp-mail NODE RECIPIENT" you must use
"nncp-exec NODE sendmail RECIPIENT".
* sendmail configuration file option is replaced with exec.
"sendmail: [...]" must be replaced with "exec: sendmail: [...]".
* Ability to override "via" configuration option for destination
node via -via command line option for following commands:
nncp-file, nncp-freq, nncp-exec.
* Chunked files, having size less than specified chunk size, will be
sent as an ordinary single file.
* Exec commands are invoked with additional NNCP_NICE and NNCP_SELF
environment variables.
* Files, that are sent as a reply to freq, have niceness level taken
from the freq packet. You can set desired niceness during nncp-freq
invocation using -replynice option.
* nncp-toss command can ignore specified packet types during processing:
-nofile, -nofreq, -noexec, -notrns.
* nncp-file command uses FreqMinSize/FreqChunked conifiguration file
options for -minsize/-chunked by default. You can turn this off by
specifying zero value.
