10 @command{nncp-daemon} can be run as @command{inetd}-service.
17 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
18 if @file{.seen} exists and treat it like file was already downloaded.
19 Possibly it was transferred out-of-bound and remote side needs to be
22 If higher priority packet is spooled, then @command{nncp-daemon} will
23 queue its sending first, interrupting lower priority transmissions.
25 Simple packet rate limiter added to online-related tools
26 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
28 Ability to specify niceness with symbolic notation:
29 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
31 Changed default niceness levels:
32 for @command{nncp-exec} from 64 to 96,
33 for @command{nncp-freq} from 64 to 160,
34 for @command{nncp-file} from 196 to 224.
41 @strong{Incompatible} @emph{bundle} archive format changes and
42 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
43 valid tar archives, but Go 1.9 made them invalid because of long paths
44 inside. NNCP accidentally was dependant on that bug. Explicit adding of
45 @file{NNCP/} directory in archive restores workability with valid tar
53 Ability to disable relaying at all using @verb{|-via -|} command line option.
60 @strong{Incompatible} plain packet format changes. Older versions are
63 Ability to queue remote command execution, by configuring @option{exec}
64 option in configuration file and using @command{nncp-exec} command:
67 @command{nncp-mail} command is replaced with more flexible
68 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
69 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
71 @option{sendmail} configuration file option is replaced with
72 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
73 @verb{|exec: sendmail: [...]|}.
76 Ability to override @option{via} configuration option for destination
77 node via @option{-via} command line option for following commands:
78 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
80 Chunked files, having size less than specified chunk size, will be sent
81 as an ordinary single file.
83 Exec commands are invoked with additional @env{NNCP_NICE} and
84 @env{NNCP_SELF} environment variables.
86 Files, that are sent as a reply to freq, have niceness level taken from
87 the freq packet. You can set desired niceness during @command{nncp-freq}
88 invocation using @option{-replynice} option.
90 @command{nncp-toss} command can ignore specified packet types during
91 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
94 @command{nncp-file} command uses
95 @option{FreqMinSize}/@option{FreqChunked} configuration file options
96 for @option{-minsize}/@option{-chunked} by default. You can turn this
97 off by specifying zero value.
104 @strong{Incompatible} encrypted/eblob packet format changes. Older
105 versions are not supported.
107 Twofish encryption algorithm is replaced with ChaCha20. It is much more
108 faster. One cryptographic primitive less.
110 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
111 another cryptographic primitive less (assuming that BLAKE2X is nearly
112 identical to BLAKE2).
119 @strong{Incompatible} encrypted packet format changes. Older versions
122 @command{nncp-bundle} command can either create stream of encrypted
123 packets, or digest it. It is useful when dealing with stdin/stdout based
124 transmission methods (like writing to CD-ROM without intermediate
125 prepared ISO image and working with tape drives).
127 @command{nncp-toss} is able to create @file{.seen} files preventing
128 duplicate packets receiving.
130 Single background checksum verifier worker is allowed in
131 @command{nncp-call}. This is helpful when thousands of small inbound
132 packets could create many goroutines.
134 Ability to override path to spool directory and logfile through either
135 command line argument, or environment variable.
137 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
138 @file{.part}, @file{.lock} and temporary files.
142 @section Release 0.12
145 Sendmail command is called with @env{NNCP_SENDER} environment variable.
149 @section Release 0.11
152 @command{nncp-stat}'s command output is sorted by node name.
156 @section Release 0.10
159 @command{nncp-freq}'s @file{DST} argument is optional now. Last
160 @file{SRC} path's element will be used by default.
167 Fix @option{-rx}/@option{-tx} arguments processing in
168 @command{nncp-call} command. They were ignored.
175 Little bugfix in @command{nncp-file} command, where @option{-minsize}
176 option for unchunked transfer was not in KiBs, but in bytes.
183 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
184 temporary file for that.
187 Chunked files transmission appeared with corresponding
188 @command{nncp-reass} command and @option{freqchunked} configuration file
189 entry. Useful for transferring big files over small storage devices.
192 @option{freqminsize} configuration file option, analogue to
193 @option{-minsize} one.
196 @command{nncp-xfer}'s @option{-force} option is renamed to
197 @option{-mkdir} for clarity.
200 @option{-minsize} option is specified in KiBs, not bytes, for
204 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
205 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
206 common prefix and are grouped together for convenience.
209 @command{nncp-cfgenc} command appeared, allowing configuration file
210 encryption/decryption, for keeping it safe without any either OpenPGP or
214 Cryptographic libraries (dependencies) are updated.
220 @item Small @command{nncp-rm} command appeared.
221 @item Cryptographic libraries (dependencies) are updated.
227 @item Trivial small fix in default niceness level of @command{nncp-file}
228 and @command{nncp-freq} commands.
234 @item Small fix in @command{nncp-call}, @command{nncp-caller},
235 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
237 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
238 shorter and more convenient to use.
239 @item @command{nncp-mincfg} command appeared: helper allowing to create
240 minimalistic stripped down configuration file without private keys,
241 that is useful during @command{nncp-xfer} usage.
246 Fixed compatibility with Go 1.6.
251 @item @strong{Incompatible} packet's format change (magic number is
252 changed too): size field is encrypted and is not send in plaintext
254 @item @option{-minsize} option gives ability to automatically pad
255 outgoing packets to specified minimal size.
256 @item @command{nncp-daemon} and
257 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
258 packets appearance in the background while connected. Remote side is
259 immediately notified.
260 @item @option{-onlinedeadline} option gives ability to configure timeout
261 of inactivity of online connection, when it could be disconnected. It
262 could be used to keep connection alive for a long time.
263 @item @option{-maxonlinetime} option gives ability to set maximal
264 allowable online connection aliveness time.
265 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
266 @item @command{nncp-pkt} command can decompress the data.
