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}).
21 Ability to specify niceness with symbolic notation:
22 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
24 Changed default niceness levels:
25 for @command{nncp-exec} from 64 to 96,
26 for @command{nncp-freq} from 64 to 160,
27 for @command{nncp-file} from 196 to 224.
34 @strong{Incompatible} @emph{bundle} archive format changes and
35 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
36 valid tar archives, but Go 1.9 made them invalid because of long paths
37 inside. NNCP accidentally was dependant on that bug. Explicit adding of
38 @file{NNCP/} directory in archive restores workability with valid tar
46 Ability to disable relaying at all using @verb{|-via -|} command line option.
53 @strong{Incompatible} plain packet format changes. Older versions are
56 Ability to queue remote command execution, by configuring @option{exec}
57 option in configuration file and using @command{nncp-exec} command:
60 @command{nncp-mail} command is replaced with more flexible
61 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
62 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
64 @option{sendmail} configuration file option is replaced with
65 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
66 @verb{|exec: sendmail: [...]|}.
69 Ability to override @option{via} configuration option for destination
70 node via @option{-via} command line option for following commands:
71 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
73 Chunked files, having size less than specified chunk size, will be sent
74 as an ordinary single file.
76 Exec commands are invoked with additional @env{NNCP_NICE} and
77 @env{NNCP_SELF} environment variables.
79 Files, that are sent as a reply to freq, have niceness level taken from
80 the freq packet. You can set desired niceness during @command{nncp-freq}
81 invocation using @option{-replynice} option.
83 @command{nncp-toss} command can ignore specified packet types during
84 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
87 @command{nncp-file} command uses
88 @option{FreqMinSize}/@option{FreqChunked} configuration file options
89 for @option{-minsize}/@option{-chunked} by default. You can turn this
90 off by specifying zero value.
97 @strong{Incompatible} encrypted/eblob packet format changes. Older
98 versions are not supported.
100 Twofish encryption algorithm is replaced with ChaCha20. It is much more
101 faster. One cryptographic primitive less.
103 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
104 another cryptographic primitive less (assuming that BLAKE2X is nearly
105 identical to BLAKE2).
112 @strong{Incompatible} encrypted packet format changes. Older versions
115 @command{nncp-bundle} command can either create stream of encrypted
116 packets, or digest it. It is useful when dealing with stdin/stdout based
117 transmission methods (like writing to CD-ROM without intermediate
118 prepared ISO image and working with tape drives).
120 @command{nncp-toss} is able to create @file{.seen} files preventing
121 duplicate packets receiving.
123 Single background checksum verifier worker is allowed in
124 @command{nncp-call}. This is helpful when thousands of small inbound
125 packets could create many goroutines.
127 Ability to override path to spool directory and logfile through either
128 command line argument, or environment variable.
130 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
131 @file{.part}, @file{.lock} and temporary files.
135 @section Release 0.12
138 Sendmail command is called with @env{NNCP_SENDER} environment variable.
142 @section Release 0.11
145 @command{nncp-stat}'s command output is sorted by node name.
149 @section Release 0.10
152 @command{nncp-freq}'s @file{DST} argument is optional now. Last
153 @file{SRC} path's element will be used by default.
160 Fix @option{-rx}/@option{-tx} arguments processing in
161 @command{nncp-call} command. They were ignored.
168 Little bugfix in @command{nncp-file} command, where @option{-minsize}
169 option for unchunked transfer was not in KiBs, but in bytes.
176 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
177 temporary file for that.
180 Chunked files transmission appeared with corresponding
181 @command{nncp-reass} command and @option{freqchunked} configuration file
182 entry. Useful for transferring big files over small storage devices.
185 @option{freqminsize} configuration file option, analogue to
186 @option{-minsize} one.
189 @command{nncp-xfer}'s @option{-force} option is renamed to
190 @option{-mkdir} for clarity.
193 @option{-minsize} option is specified in KiBs, not bytes, for
197 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
198 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
199 common prefix and are grouped together for convenience.
202 @command{nncp-cfgenc} command appeared, allowing configuration file
203 encryption/decryption, for keeping it safe without any either OpenPGP or
207 Cryptographic libraries (dependencies) are updated.
213 @item Small @command{nncp-rm} command appeared.
214 @item Cryptographic libraries (dependencies) are updated.
220 @item Trivial small fix in default niceness level of @command{nncp-file}
221 and @command{nncp-freq} commands.
227 @item Small fix in @command{nncp-call}, @command{nncp-caller},
228 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
230 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
231 shorter and more convenient to use.
232 @item @command{nncp-mincfg} command appeared: helper allowing to create
233 minimalistic stripped down configuration file without private keys,
234 that is useful during @command{nncp-xfer} usage.
239 Fixed compatibility with Go 1.6.
244 @item @strong{Incompatible} packet's format change (magic number is
245 changed too): size field is encrypted and is not send in plaintext
247 @item @option{-minsize} option gives ability to automatically pad
248 outgoing packets to specified minimal size.
249 @item @command{nncp-daemon} and
250 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
251 packets appearance in the background while connected. Remote side is
252 immediately notified.
253 @item @option{-onlinedeadline} option gives ability to configure timeout
254 of inactivity of online connection, when it could be disconnected. It
255 could be used to keep connection alive for a long time.
256 @item @option{-maxonlinetime} option gives ability to set maximal
257 allowable online connection aliveness time.
258 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
259 @item @command{nncp-pkt} command can decompress the data.
