15 int typestr="portnumber"
19 para_server listens on this tcp port for incoming connections
20 from clients such as para_client. If the default port is
21 changed, the corresponding option of para_client must be used
22 to connect to para_server.
27 "run as background daemon"
31 Note that para_server refuses to start in daemon mode if no
32 logfile was specified.
37 "run as the given user"
41 para_server does not need any special privileges. If started
42 as root (EUID == 0) this option must be given at the command
43 line (not in the configuration file) so that para_server
44 can drop the root privileges right after parsing the command
45 line options, but before parsing the configuration file. In
46 this case, real/effective/saved UID are all set to the UID
47 of 'name'. As the configuration file is read afterwards,
48 those options that have a default value depending on the UID
49 (e.g. the directory for the configuration file) are computed
50 by using the uid of 'name'. This option has no effect if
51 para_server is started as a non-root user (i.e. EUID != 0)
58 string typestr="group"
61 This option sets the group id according to 'group'. This option
62 is silently ignored if EUID != 0. Otherwise, real/effective
63 GID and the saved set-group ID are all set to the GID given by
64 'group'. Must not be given in the config file.

84 "(default='~/.paraslash/server.conf'"
85 string typestr="filename"
88 para_server reads its config file right after parsing
89 the options that were given at the command line. If an
90 option is given both at the command line and in the

110 "start playing on startup"
113 option "autoplay_delay" -
114 #~~~~~~~~~~~~~~~~~~~~~~~~
115 "time to wait before streaming"
121 If para_server is started with the autoplay option, this option
122 may be used to set up a delay before para_server streams its
123 first audio file. This is useful for example if para_server
124 and para_audiod are started during system startup. The delay
125 time should be choosen large enough so that para_audiod is
126 already up when para_server starts to stream. Of course, this
127 option depends on the autoplay option.
129 option "announce_time" A
130 #~~~~~~~~~~~~~~~~~~~~~~~
131 "grace time for clients"
137 Clients such as para_audiod connect to para_server and execute
138 the stat command to find out whether an audio stream is
139 currently available. This sets the delay betweeen announcing
140 the stream via the output of the stat command and sending
141 the first chunk of data.

148 option "afs_database_dir" D
149 #~~~~~~~~~~~~~~~~~~~~~~~~~~
150 "location of the database"
151 string typestr="path"
154 Where para_server should look for the osl
155 database of the audio file selector. The default is
156 '~/.paraslash/afs_database'.
159 option "afs_socket" s
160 #~~~~~~~~~~~~~~~~~~~~
161 "Command socket for afs"
162 string typestr="path"
163 default="/var/paraslash/afs_command_socket"
166 For each server command that is handled by the audio file
167 selector, the child process of para_server connects to the
168 audio file selector via a local socket. This option specifies
169 the location of that socket in the file system.
171 option "afs_initial_mode" i
172 #~~~~~~~~~~~~~~~~~~~~~~~~~~
174 "Mood or playlist to load on startup."
175 string typestr="<specifier>/<name>"
179 The argument of this option must be prefixed with either 'p/'
180 or 'm/' to indicate whether a playlist or a mood should be
182 --afs_initial_mode p/foo
183 loads the playlist named 'foo'.

187 section "http sender"
188 #####################
193 "tcp port for http streaming"
194 int typestr="portnumber"
198 The http sender of para_server listens on this port for
199 incoming connections. Clients are expected to send the usual
200 http request message such as 'GET / HTTP/'.
203 option "http_default_deny" -
204 #~~~~~~~~~~~~~~~~~~~~~~~~~~~
205 "make the http ACL a whitelist"
208 The default is to use blacklists instead, i.e. connections
209 to the http sender are allowed unless the connecting host
210 matches a pattern given by a http_access option. This allows
211 to use access control the other way round: Connections are
212 denied from hosts which are not explicitly allowed by one or
213 more http_access options.
216 option "http_access" -
217 #~~~~~~~~~~~~~~~~~~~~~
218 "add an entry to the http ACL"
219 string typestr="a.b.c.d/n"
223 Add given host/network to access control list (whitelist if
224 http_default_deny was given, blacklist otherwise) before
225 opening the tcp port. This option can be given multiple
226 times. Example: '192.168.0.0/24' whitelists/blacklists the
227 256 hosts 192.168.0.x
230 option "http_no_autostart" -
231 #~~~~~~~~~~~~~~~~~~~~~~~~~~~
232 "do not open tcp port on startup"
235 If this option is given, the http sender does not listen on
236 its tcp port. It may be instructed to open this port at a
237 later time by using the sender command.
240 option "http_max_clients" -
241 #~~~~~~~~~~~~~~~~~~~~~~~~~~
242 "maximal number of connections"
247 The http sender will refuse connections if already that number
248 of clients are currently connected. A non-positive value
249 (the default) allows an unlimited number of simultaneous

300 option "ortp_target" -
301 #~~~~~~~~~~~~~~~~~~~~~
303 string typestr="a.b.c.d:p"
307 Add given host/port to the list of targets. This option
308 can be given multiple times. Example: '224.0.1.38:1500'
309 instructs the ortp sender to send to udp port 1500 on host
310 224.0.1.38 (unassigned ip in the Local Network Control Block
311 224.0.0/24). This is useful for LAN-streaming.
314 option "ortp_no_autostart" -
315 #~~~~~~~~~~~~~~~~~~~~~~~~~~~
316 "do not start sending"
319 If this option is given, ortp streaming may be activated at
320 a later time by using the sender command.
323 option "ortp_default_port" -
324 #~~~~~~~~~~~~~~~~~~~~~~~~~~~
325 "udp port to send to"
330 option "ortp_header_interval" H
331 #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
332 "duration for sending header"
337 As the ortp sender has no idea about connected clients it
338 sends the audio file header periodically if necessary. This
339 option is used to specify the duration of the interval between
340 sending the header. Shorter values decrease the average time
341 clients have to wait before being able to start playback,
342 but this also increases the amount network traffic. Note
343 that this affects only ogg vorbis streams as this is the only
344 audio format that needs an audio file header.
347 option "ortp_jitter_compensation" j
348 #~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
349 "configure jitter compensation"
354 ortp's adaptive jitter compensation gets activated whenever
355 this value is greater than zero. See the ortp documentation
356 about details on this feature.
