===МетатрекерыMetatrackers===

Метатрекер - это сервер, который сообщает узлам о доступных трекерах и стартовых узлахMetatracker is a server which informs nodes about available trackers and start nodes.

Metatracker's URL метатрекера задается на источнике при создании трансляции и записывается в транспортный файлis given at the source when creating a broadcast and is recorded to the transport file.

Метатрекеры позволяют динамически добавлять трекеры иMetatrackers allow to add trackers and/или стартовые узлы для трансляции без необходимости перезапуска трансляции и пересоздания транспортного файлаor start nodes for the broadcast automatically without the need to restart the broadcast and recreate the transport file.

Пример запуска источника с метатрекеромExample of launching a source with the metatracker:

Метатрекер принимает запросы по протоколу Metatracker accepts requests via HTTP и выдает ответ в формате protocol and gives responds in JSONformat, поэтому метатрекер может быть реализован на базе любого веб-сервераtherefore the metatracker can be implemented on the basis of any web server.

Каждый узел при запуске трансляции отправляет на метатрекер When broadcast starts, each node sends to the metatracker HTTP GET запрос с параметром request with parameter <tt>infohash</tt> (хеш трансляции в виде broadcast hash as a hex-строкиstring). Пример запроса на метатрекерExample of the request to the metatracker:

Формат ответаRespond format:

гдеwhere*tracker_url_1, tracker_url_2 - trackers' URL трекеров*node1_address, node2_address - адреса стартовых узлов в виде строк в формате start nodes' addresses as strings in ip:port format (напримерfor example, 192.168.1.2:8632)*UPDATE_INTERVAL_IN_SECONDS - интервал обновления в секундах update interval in seconds (как часто каждый клиент должен повторно обращаться на метатрекерhow often each client has to reapply to metatreker)

===ВебNode's web-интерфейс узлаinterface===Every node has web-interface to view current status, as well as options to change some of the parameters "on the fly" (without restarting the node). Web-interface works on the main port of the node (specified by parameter <tt>--port</tt>). By default web-interface is available only from the same machine, from which the node was launched.To allow remote access, you have to launch the node with option <tt>--service-remote-access</tt>.Also you can set a password for web-interface to prevent unauthorized access, using option <tt>--service-access-token</tt> Full list of options to customize web-interface:*<tt>--stats-report-interval</tt> - frequency of node's statistics update, in seconds (by default 60)*<tt>--stats-report-peers</tt> - if this option is set, a list of nodes that are currently connected to the node will be shown in monitoring (by default node list is not displayed).*<tt>--service-remote-access</tt> - allow remote access to web-interface*<tt>--service-access-token</tt> - set a password for web-interface Access to web-interface is performed via HTTP-GET request to the node's port:*monitoring - <nowiki>http://node.address:PORT/app/TOKEN/monitoring</nowiki>*control - <nowiki>http://node.address:PORT/app/TOKEN/update</nowiki> If node was launched without option <tt>--service-access-token</tt>, then TOKEN is not specified in the request.<br/>Responses are given in JSON format. Examples:*request to the node without the password for web-interface: <nowiki>http://192.168.1.3:8640/app/monitor</nowiki>*request to the node with the password "qwerty" for web-interface: <nowiki>http://192.168.1.3:8640/app/qwerty/monitor</nowiki> ====Monitoring====Interface of monitoring gives the following information:*<tt>version</tt> - node's version*<tt>max_connections</tt> - maximum number of TCP-connections*<tt>max_peers</tt> - maximum number of concurrently connected nodes*<tt>max_upload_slots</tt> - maximum number of opened upload slots*<tt>download_speed</tt> - current speed of data download (byte/s)*<tt>upload_speed</tt> - current speed of data upload (byte/s)*<tt>connected_peers_count</tt> - number of connected nodes*<tt>connected_peers</tt> - list of connected nodes (empty, if option --stats-report-peers is not set)*<tt>upload_slots</tt> - current number of upload slots ====Management====To change node's parameters "on the fly" you have to send a request of the following kind to web-interface: <nowiki>http://192.168.1.3:8640/app/update?param1=value1&param2=value2...</nowiki>param1 and param2 set names of parameters that have to be updated, value1 and value2 are new values for the parameters. Available for updating parameters:*<tt>max_peers</tt>*<tt>max_upload_slots</tt> Example: <nowiki>http://192.168.1.3:8640/app/update?max_peers=100&max_upload_slots=30</nowiki> (keep the connection with 100 nodes simultaneously and open 30 upload slots) ===Traffic filtration===Starting from version 3.0.2 an ability to filter traffic at special nodes (source, support node and start node) was added. You can filter by ip-addresses or by geotargeting. Rules for the filtration should be put in a separate configuration file, path to which is passed in a special node in parameter --ip-filter-config. Configuration file is a text file in JSON format with the following structure: <tt>{ "groups": { "<group_1>": { "addresses": ["<ip_address_1>", "<ip_address_2>", ...], "countries": ["<country_code_1>", "<country_code_2>", ...] }, "<group_2>": { "addresses": ["<ip_address_1>", "<ip_address_2>", ...], "countries": ["<country_code_1>", "<country_code_2>", ...] }, }, "blacklist": { "addresses": ["<ip_address_1>", "<ip_address_2>", ...], "countries": ["<country_code_1>", "<country_code_2>", ...], "groups": ["<group_1>", "<group_2>", ...] }, "whitelist": { "addresses": ["<ip_address_1>", "<ip_address_2>", ...], "countries": ["<country_code_1>", "<country_code_2>", ...], "groups": ["<group_1>", "<group_2>", ...] }, "limit_groups": { "<group_1>": "30%", "<group_2>": "10%" } }</tt> Section <tt>groups</tt> is used to create named groups, that can be referenced in other sections of the file.Each group may consist of an array ip-addresses (<tt>addresses</tt>) or country codes (<tt>countries</tt>). Array <tt>addresses</tt> may contain addresses of individual hosts, as well as addresses of subnetworks in the format xx.xx.xx.xx/yy. At this moment it is allowed to use only subnetworks /24, /16 and /8. Array <tt>countries</tt> has to contain country codes in uppercase (according to the base [https://www.maxmind.com MaxMind]) Section <tt>whitelist</tt> sets a white list. The node rejects connections from all addresses that are not included in a white list.
