77 @strong{spool} field contains an absolute path to @ref{Spool, spool}
78 directory. @strong{log} field contains an absolute path to @ref{Log,
82 @strong{notify} section contains notification settings for successfully
83 tossed file and freq packets. Corresponding @strong{from} and
84 @strong{to} fields will be substituted in notification email message.
85 @emph{neigh/self/exec/sendmail} will be used as a local mailer. You can
86 omit either of those two @emph{from}/@emph{to} sections to omit
87 corresponding notifications, or the whole section at once.
89 @strong{self} section contains our node's private keypairs.
90 @strong{exch*} and @strong{sign*} are used during @ref{Encrypted,
91 encrypted} packet creation. @strong{noise*} are used during @ref{Sync,
92 synchronization protocol} working in @ref{nncp-call}/@ref{nncp-daemon}.
94 @strong{neigh} section contains all known neighbours information. It
95 always has @strong{self} neighbour that is copy of our node's public
96 data (public keys). It is useful for copy-paste sharing with your
97 friends. Each section's key is a human-readable name of the neighbour.
99 Except for @emph{id}, @emph{exchpub} and @emph{signpub} each neighbour
100 node has the following fields:
105 If present, then node can be online called using @ref{Sync,
106 synchronization protocol}. Contains authentication public key.
110 Dictionary consisting of handles and corresponding command line
111 arguments. In example above there are @command{sendmail} handles,
112 @command{warcer}, @command{wgeter} and @command{flag} one. Remote node
113 can queue some handle execution with providing additional command line
114 arguments and the body fed to command's stdin.
116 @verb{|sendmail: ["/usr/sbin/sendmail", "-t"]|} handle, when called by
117 @verb{|echo hello world | nncp-exec OURNODE sendmail ARG0 ARG1 ARG2|}
118 command, will execute:
124 /usr/sbin/sendmail -t ARG0 ARG1 ARG2
127 feeding @verb{|hello world\n|} to that started @command{sendmail}
132 Full path to directory where all file uploads will be saved. May be
133 omitted to forbid file uploading on that node.
137 Full path to directory from where file requests will queue files for
138 transmission. May be omitted to forbid freqing from that node.
141 If set, then enable @ref{Chunked, chunked} file transmission during
142 freqing. This is the desired chunk size in KiBs.
145 If set, then apply @ref{OptMinSize, -minsize} option during file
150 An array of node identifiers that will be used as a relay to that node.
151 For example @verb{|[foo,bar]|} means that packet can reach current node
152 by transitioning through @emph{foo} and then @emph{bar} nodes. May be
153 omitted if direct connection exists and no relaying is required.
157 Dictionary containing known network addresses of the node. Each key is
158 human-readable name of the address. For direct TCP connections use
159 @verb{|host:port|} format, pointing to @ref{nncp-daemon}'s listening
160 instance. Also you can pipe connection through the external command
161 using @verb{#|some command#} format. @code{/bin/sh -c "some command"}
162 will start and its stdin/stdout used as a connection. May be omitted if
163 either no direct connection exists, or @ref{nncp-call} is used with
164 forced address specifying.
168 If greater than zero, then at most *rate packets per second will be
169 sent/received after the handshake. It could be used as crude bandwidth
170 traffic shaper: each packet has at most 64 KiB payload size. Could be
171 omitted at all -- no rate limits.
173 @anchor{CfgOnlineDeadline}
175 Online connection deadline of node inactivity in seconds. It is the time
176 connection considered dead after not receiving/sending any packets and
177 node must disconnect. By default it is set to 10 seconds -- that means
178 disconnecting after 10 seconds when no packets received and transmitted.
179 This can be set to rather high values to keep connection alive (to
180 reduce handshake overhead and delays), wait for appearing packets ready
181 to send and notifying remote side about their appearance.
183 @anchor{CfgMaxOnlineTime}
185 If greater than zero, then it is maximal amount of time connect could be
186 alive. Forcefully disconnect if it is exceeded.
190 List of @ref{Call, call configuration}s. Can be omitted if
191 @ref{nncp-caller} won't be used to call that node.
