10 @strong{Incompatible} encrypted and eblob packet format change: AEAD
11 encryption mode with 128 KiB blocks is used now, because previously
12 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
13 decrypted data to external command. Older versions are not supported.
15 Available free space checking before copying in @command{nncp-xfer},
16 @command{nncp-daemon}, @command{nncp-call(er)}.
18 @command{nncp-call} has ability only to list packets on remote node,
19 without their transmission.
21 @command{nncp-call} has ability to transfer only specified packets.
23 Workability of @option{xxrate} preference in @option{calls}
24 configuration file section.
26 Dependant libraries are updated.
30 Begin using of @code{go.mod} subsystem.
37 @command{nncp-daemon} can be run as @command{inetd}-service.
44 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
45 if @file{.seen} exists and treat it like file was already downloaded.
46 Possibly it was transferred out-of-bound and remote side needs to be
49 If higher priority packet is spooled, then @command{nncp-daemon} will
50 queue its sending first, interrupting lower priority transmissions.
52 Simple packet rate limiter added to online-related tools
53 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
55 Ability to specify niceness with symbolic notation:
56 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
58 Changed default niceness levels:
59 for @command{nncp-exec} from 64 to 96,
60 for @command{nncp-freq} from 64 to 160,
61 for @command{nncp-file} from 196 to 224.
68 @strong{Incompatible} @emph{bundle} archive format changes and
69 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
70 valid tar archives, but Go 1.9 made them invalid because of long paths
71 inside. NNCP accidentally was dependant on that bug. Explicit adding of
72 @file{NNCP/} directory in archive restores workability with valid tar
80 Ability to disable relaying at all using @verb{|-via -|} command line option.
87 @strong{Incompatible} plain packet format changes. Older versions are
90 Ability to queue remote command execution, by configuring @option{exec}
91 option in configuration file and using @command{nncp-exec} command:
94 @command{nncp-mail} command is replaced with more flexible
95 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
96 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
98 @option{sendmail} configuration file option is replaced with
99 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
100 @verb{|exec: sendmail: [...]|}.
103 Ability to override @option{via} configuration option for destination
104 node via @option{-via} command line option for following commands:
105 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
107 Chunked files, having size less than specified chunk size, will be sent
108 as an ordinary single file.
110 Exec commands are invoked with additional @env{NNCP_NICE} and
111 @env{NNCP_SELF} environment variables.
113 Files, that are sent as a reply to freq, have niceness level taken from
114 the freq packet. You can set desired niceness during @command{nncp-freq}
115 invocation using @option{-replynice} option.
117 @command{nncp-toss} command can ignore specified packet types during
118 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
121 @command{nncp-file} command uses
122 @option{FreqMinSize}/@option{FreqChunked} configuration file options
123 for @option{-minsize}/@option{-chunked} by default. You can turn this
124 off by specifying zero value.
131 @strong{Incompatible} encrypted/eblob packet format changes. Older
132 versions are not supported.
134 Twofish encryption algorithm is replaced with ChaCha20. It is much more
135 faster. One cryptographic primitive less.
137 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
138 another cryptographic primitive less (assuming that BLAKE2X is nearly
139 identical to BLAKE2).
146 @strong{Incompatible} encrypted packet format changes. Older versions
149 @command{nncp-bundle} command can either create stream of encrypted
150 packets, or digest it. It is useful when dealing with stdin/stdout based
151 transmission methods (like writing to CD-ROM without intermediate
152 prepared ISO image and working with tape drives).
154 @command{nncp-toss} is able to create @file{.seen} files preventing
155 duplicate packets receiving.
157 Single background checksum verifier worker is allowed in
158 @command{nncp-call}. This is helpful when thousands of small inbound
159 packets could create many goroutines.
161 Ability to override path to spool directory and logfile through either
162 command line argument, or environment variable.
164 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
165 @file{.part}, @file{.lock} and temporary files.
169 @section Release 0.12
172 Sendmail command is called with @env{NNCP_SENDER} environment variable.
176 @section Release 0.11
179 @command{nncp-stat}'s command output is sorted by node name.
183 @section Release 0.10
186 @command{nncp-freq}'s @file{DST} argument is optional now. Last
187 @file{SRC} path's element will be used by default.
194 Fix @option{-rx}/@option{-tx} arguments processing in
195 @command{nncp-call} command. They were ignored.
202 Little bugfix in @command{nncp-file} command, where @option{-minsize}
203 option for unchunked transfer was not in KiBs, but in bytes.
210 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
211 temporary file for that.
214 Chunked files transmission appeared with corresponding
215 @command{nncp-reass} command and @option{freqchunked} configuration file
216 entry. Useful for transferring big files over small storage devices.
219 @option{freqminsize} configuration file option, analogue to
220 @option{-minsize} one.
223 @command{nncp-xfer}'s @option{-force} option is renamed to
224 @option{-mkdir} for clarity.
227 @option{-minsize} option is specified in KiBs, not bytes, for
231 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
232 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
233 common prefix and are grouped together for convenience.
236 @command{nncp-cfgenc} command appeared, allowing configuration file
237 encryption/decryption, for keeping it safe without any either OpenPGP or
241 Cryptographic libraries (dependencies) are updated.
247 @item Small @command{nncp-rm} command appeared.
248 @item Cryptographic libraries (dependencies) are updated.
254 @item Trivial small fix in default niceness level of @command{nncp-file}
255 and @command{nncp-freq} commands.
261 @item Small fix in @command{nncp-call}, @command{nncp-caller},
262 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
264 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
265 shorter and more convenient to use.
266 @item @command{nncp-mincfg} command appeared: helper allowing to create
267 minimalistic stripped down configuration file without private keys,
268 that is useful during @command{nncp-xfer} usage.
273 Fixed compatibility with Go 1.6.
278 @item @strong{Incompatible} packet's format change (magic number is
279 changed too): size field is encrypted and is not send in plaintext
281 @item @option{-minsize} option gives ability to automatically pad
282 outgoing packets to specified minimal size.
283 @item @command{nncp-daemon} and
284 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
285 packets appearance in the background while connected. Remote side is
286 immediately notified.
287 @item @option{-onlinedeadline} option gives ability to configure timeout
288 of inactivity of online connection, when it could be disconnected. It
289 could be used to keep connection alive for a long time.
290 @item @option{-maxonlinetime} option gives ability to set maximal
291 allowable online connection aliveness time.
292 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
293 @item @command{nncp-pkt} command can decompress the data.
