I am pleased to announce NNCP 6.1.0 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.
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:
* Optimization: most commands do not keep opened file descriptors
now. Previously you can exceed maximal number of opened files if
you have got many packets in the spool directory.
* Optimization: do not close file descriptor of the file we download
online. Previously each chunk lead to expensive open/close calls.
* Online downloaded files are saved with ".nock" (non-checksummed)
suffix, waiting either for "nncp-check", or online daemons to
perform integrity check.
* Optimization: files, that are not resumed, are checksummed
immediately during the online download, skipping
".nock"-intermediate step.
* Ability to store encrypted packet’s header in ".hdr" file, close to
the packet itself. That can greatly increase performance of
packets listing on filesystems with big block’s size.
