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 Dependant libraries are updated.
24 @command{nncp-daemon} can be run as @command{inetd}-service.
31 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
32 if @file{.seen} exists and treat it like file was already downloaded.
33 Possibly it was transferred out-of-bound and remote side needs to be
36 If higher priority packet is spooled, then @command{nncp-daemon} will
37 queue its sending first, interrupting lower priority transmissions.
39 Simple packet rate limiter added to online-related tools
40 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
42 Ability to specify niceness with symbolic notation:
43 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
45 Changed default niceness levels:
46 for @command{nncp-exec} from 64 to 96,
47 for @command{nncp-freq} from 64 to 160,
48 for @command{nncp-file} from 196 to 224.
55 @strong{Incompatible} @emph{bundle} archive format changes and
56 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
57 valid tar archives, but Go 1.9 made them invalid because of long paths
58 inside. NNCP accidentally was dependant on that bug. Explicit adding of
59 @file{NNCP/} directory in archive restores workability with valid tar
67 Ability to disable relaying at all using @verb{|-via -|} command line option.
74 @strong{Incompatible} plain packet format changes. Older versions are
77 Ability to queue remote command execution, by configuring @option{exec}
78 option in configuration file and using @command{nncp-exec} command:
81 @command{nncp-mail} command is replaced with more flexible
82 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
83 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
85 @option{sendmail} configuration file option is replaced with
86 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
87 @verb{|exec: sendmail: [...]|}.
90 Ability to override @option{via} configuration option for destination
91 node via @option{-via} command line option for following commands:
92 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
94 Chunked files, having size less than specified chunk size, will be sent
95 as an ordinary single file.
97 Exec commands are invoked with additional @env{NNCP_NICE} and
98 @env{NNCP_SELF} environment variables.
100 Files, that are sent as a reply to freq, have niceness level taken from
101 the freq packet. You can set desired niceness during @command{nncp-freq}
102 invocation using @option{-replynice} option.
104 @command{nncp-toss} command can ignore specified packet types during
105 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
108 @command{nncp-file} command uses
109 @option{FreqMinSize}/@option{FreqChunked} configuration file options
110 for @option{-minsize}/@option{-chunked} by default. You can turn this
111 off by specifying zero value.
118 @strong{Incompatible} encrypted/eblob packet format changes. Older
119 versions are not supported.
121 Twofish encryption algorithm is replaced with ChaCha20. It is much more
122 faster. One cryptographic primitive less.
124 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
125 another cryptographic primitive less (assuming that BLAKE2X is nearly
126 identical to BLAKE2).
133 @strong{Incompatible} encrypted packet format changes. Older versions
136 @command{nncp-bundle} command can either create stream of encrypted
137 packets, or digest it. It is useful when dealing with stdin/stdout based
138 transmission methods (like writing to CD-ROM without intermediate
139 prepared ISO image and working with tape drives).
141 @command{nncp-toss} is able to create @file{.seen} files preventing
142 duplicate packets receiving.
144 Single background checksum verifier worker is allowed in
145 @command{nncp-call}. This is helpful when thousands of small inbound
146 packets could create many goroutines.
148 Ability to override path to spool directory and logfile through either
149 command line argument, or environment variable.
151 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
152 @file{.part}, @file{.lock} and temporary files.
156 @section Release 0.12
159 Sendmail command is called with @env{NNCP_SENDER} environment variable.
163 @section Release 0.11
166 @command{nncp-stat}'s command output is sorted by node name.
170 @section Release 0.10
173 @command{nncp-freq}'s @file{DST} argument is optional now. Last
174 @file{SRC} path's element will be used by default.
181 Fix @option{-rx}/@option{-tx} arguments processing in
182 @command{nncp-call} command. They were ignored.
189 Little bugfix in @command{nncp-file} command, where @option{-minsize}
190 option for unchunked transfer was not in KiBs, but in bytes.
197 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
198 temporary file for that.
201 Chunked files transmission appeared with corresponding
202 @command{nncp-reass} command and @option{freqchunked} configuration file
203 entry. Useful for transferring big files over small storage devices.
206 @option{freqminsize} configuration file option, analogue to
207 @option{-minsize} one.
210 @command{nncp-xfer}'s @option{-force} option is renamed to
211 @option{-mkdir} for clarity.
214 @option{-minsize} option is specified in KiBs, not bytes, for
218 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
219 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
220 common prefix and are grouped together for convenience.
223 @command{nncp-cfgenc} command appeared, allowing configuration file
224 encryption/decryption, for keeping it safe without any either OpenPGP or
228 Cryptographic libraries (dependencies) are updated.
234 @item Small @command{nncp-rm} command appeared.
235 @item Cryptographic libraries (dependencies) are updated.
241 @item Trivial small fix in default niceness level of @command{nncp-file}
242 and @command{nncp-freq} commands.
248 @item Small fix in @command{nncp-call}, @command{nncp-caller},
249 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
251 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
252 shorter and more convenient to use.
253 @item @command{nncp-mincfg} command appeared: helper allowing to create
254 minimalistic stripped down configuration file without private keys,
255 that is useful during @command{nncp-xfer} usage.
260 Fixed compatibility with Go 1.6.
265 @item @strong{Incompatible} packet's format change (magic number is
266 changed too): size field is encrypted and is not send in plaintext
268 @item @option{-minsize} option gives ability to automatically pad
269 outgoing packets to specified minimal size.
270 @item @command{nncp-daemon} and
271 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
272 packets appearance in the background while connected. Remote side is
273 immediately notified.
274 @item @option{-onlinedeadline} option gives ability to configure timeout
275 of inactivity of online connection, when it could be disconnected. It
276 could be used to keep connection alive for a long time.
277 @item @option{-maxonlinetime} option gives ability to set maximal
278 allowable online connection aliveness time.
279 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
280 @item @command{nncp-pkt} command can decompress the data.
