This is useful for example if para_server and para_audiod are started during system startup. The delay time should be choosen large enough so that para_audiod is already up when para_server starts to stream. Of course, this option depends on the autoplay option.

" option "http_default_deny" - #~~~~~~~~~~~~~~~~~~~~~~~~~~~ "make the http ACL a whitelist" flag off details=" The default is to use blacklists instead, i.e. connections to the http sender are allowed unless the connecting host matches a pattern given by a http_access option. This allows to use access control the other way round: Connections are denied from hosts which are not explicitly allowed by one or more http_access options. " option "http_access" - #~~~~~~~~~~~~~~~~~~~~~ "add an entry to the http ACL" string typestr="a.b.c.d/n" optional multiple details=" Add given host/network to access control list (whitelist if http_default_deny was given, blacklist otherwise) before opening the tcp port.

The 'host' argument can be either an IPv4/v6 address or hostname (RFC 3986 syntax). The 'port' argument is an optional port number. If the 'port' part is absent, the 'udp_default_port' value is used. The following examples are possible targets: '10.10.1.2:8000' (host:port); '10.10.1.2' (with default port); '224.0.1.38:1500' (IPv4 multicast); 'localhost:8001' (hostname with port); '[::1]:8001' (IPv6 localhost); '[badc0de::1]' (IPv6 host with default port); '[FF00::beef]:1500' (IPv6 multicast).

This option is used to specify the duration of the interval between sending the header. Shorter values decrease the average time clients have to wait before being able to start playback, but this also increases the amount network traffic. Note that this affects only ogg vorbis streams as this is the only audio format that needs an audio file header. " option "udp_ttl" t #~~~~~~~~~~~~~~~~~ "set time to live value" int typestr="num" default="-1" optional details=" This option applies exclusively to multicast UDPv4/v6 streaming. For the sending UDPv4 socket it sets the multicast Time-To-Live value to \"num\". Traditional TTL scope values are: 0=host, 1=network, 32=same site, 64=same region, 128=same continent, 255=unrestricted. Please note however that this scoping is not a good solution: RFC 2365 e.g. presents a better alternative. When using UDPv6 multicasting, the option sets the number of multicast hops (as described in RFC 3493); a value of -1 allows the kernel to auto-select the hop value. "
