10 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
11 if @file{.seen} exists and treat it like file was already downloaded.
12 Possibly it was transferred out-of-bound and remote side needs to be
15 If higher priority packet is spooled, then @command{nncp-daemon} will
16 queue its sending first, interrupting lower priority transmissions.
18 Simple packet rate limiter added to online-related tools
19 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
26 @strong{Incompatible} @emph{bundle} archive format changes and
27 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
28 valid tar archives, but Go 1.9 made them invalid because of long paths
29 inside. NNCP accidentally was dependant on that bug. Explicit adding of
30 @file{NNCP/} directory in archive restores workability with valid tar
38 Ability to disable relaying at all using @verb{|-via -|} command line option.
45 @strong{Incompatible} plain packet format changes. Older versions are
48 Ability to queue remote command execution, by configuring @option{exec}
49 option in configuration file and using @command{nncp-exec} command:
52 @command{nncp-mail} command is replaced with more flexible
53 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
54 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
56 @option{sendmail} configuration file option is replaced with
57 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
58 @verb{|exec: sendmail: [...]|}.
61 Ability to override @option{via} configuration option for destination
62 node via @option{-via} command line option for following commands:
63 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
65 Chunked files, having size less than specified chunk size, will be sent
66 as an ordinary single file.
68 Exec commands are invoked with additional @env{NNCP_NICE} and
69 @env{NNCP_SELF} environment variables.
71 Files, that are sent as a reply to freq, have niceness level taken from
72 the freq packet. You can set desired niceness during @command{nncp-freq}
73 invocation using @option{-replynice} option.
75 @command{nncp-toss} command can ignore specified packet types during
76 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
79 @command{nncp-file} command uses
80 @option{FreqMinSize}/@option{FreqChunked} conifiguration file options
81 for @option{-minsize}/@option{-chunked} by default. You can turn this
82 off by specifying zero value.
89 @strong{Incompatible} encrypted/eblob packet format changes. Older
90 versions are not supported.
92 Twofish encryption algorithm is replaced with ChaCha20. It is much more
93 faster. One cryptographic primitive less.
95 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
96 another cryptographic primitive less (assuming that BLAKE2X is nearly
104 @strong{Incompatible} encrypted packet format changes. Older versions
107 @command{nncp-bundle} command can either create stream of encrypted
108 packets, or digest it. It is useful when dealing with stdin/stdout based
109 transmission methods (like writing to CD-ROM without intermediate
110 prepared ISO image and working with tape drives).
112 @command{nncp-toss} is able to create @file{.seen} files preventing
113 duplicate packets receiving.
115 Single background checksum verifier worker is allowed in
116 @command{nncp-call}. This is helpful when thousands of small inbound
117 packets could create many goroutines.
119 Ability to override path to spool directory and logfile through either
120 command line argument, or environment variable.
122 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
123 @file{.part}, @file{.lock} and temporary files.
127 @section Release 0.12
130 Sendmail command is called with @env{NNCP_SENDER} environment variable.
134 @section Release 0.11
137 @command{nncp-stat}'s command output is sorted by node name.
141 @section Release 0.10
144 @command{nncp-freq}'s @file{DST} argument is optional now. Last
145 @file{SRC} path's element will be used by default.
152 Fix @option{-rx}/@option{-tx} arguments processing in
153 @command{nncp-call} command. They were ignored.
160 Little bugfix in @command{nncp-file} command, where @option{-minsize}
161 option for unchunked transfer was not in KiBs, but in bytes.
168 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
169 temporary file for that.
172 Chunked files transmission appeared with corresponding
173 @command{nncp-reass} command and @option{freqchunked} configuration file
174 entry. Useful for transferring big files over small storage devices.
177 @option{freqminsize} configuration file option, analogue to
178 @option{-minsize} one.
181 @command{nncp-xfer}'s @option{-force} option is renamed to
182 @option{-mkdir} for clarity.
185 @option{-minsize} option is specified in KiBs, not bytes, for
189 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
190 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
191 common prefix and are grouped together for convenience.
194 @command{nncp-cfgenc} command appeared, allowing configuration file
195 encryption/decryption, for keeping it safe without any either OpenPGP or
199 Cryptographic libraries (dependencies) are updated.
205 @item Small @command{nncp-rm} command appeared.
206 @item Cryptographic libraries (dependencies) are updated.
212 @item Trivial small fix in default niceness level of @command{nncp-file}
213 and @command{nncp-freq} commands.
219 @item Small fix in @command{nncp-call}, @command{nncp-caller},
220 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
222 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
223 shorter and more convenient to use.
224 @item @command{nncp-mincfg} command appeared: helper allowing to create
225 minimalistic stripped down configuration file without private keys,
226 that is useful during @command{nncp-xfer} usage.
231 Fixed compatibility with Go 1.6.
236 @item @strong{Incompatible} packet's format change (magic number is
237 changed too): size field is encrypted and is not send in plaintext
239 @item @option{-minsize} option gives ability to automatically pad
240 outgoing packets to specified minimal size.
241 @item @command{nncp-daemon} and
242 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
243 packets appearance in the background while connected. Remote side is
244 immediately notified.
245 @item @option{-onlinedeadline} option gives ability to configure timeout
246 of inactivity of online connection, when it could be disconnected. It
247 could be used to keep connection alive for a long time.
248 @item @option{-maxonlinetime} option gives ability to set maximal
249 allowable online connection aliveness time.
250 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
251 @item @command{nncp-pkt} command can decompress the data.
