For Debian only <span style="color: #900;">ATTENTION!</span> In the engine (acestream-engine) is availablenearest future support for older versions will be stopped.

<span style=== Installing ACE "color: #009;">IMPORTANT!</span> All broadcasts created via new version of Ace Stream package on Ubuntu from deb-package ===You can install ACE Stream on Ubuntu without using repository(2. To do this you need to download the installation package 1 and higher) are not suppported by one client software of links below old versions (2.0.х and install it lower). If you attempt to watch a new broadcast using a package manager (for examplethe old engine, by double click on downloaded package)an error "Cannot load transport file" will appear.

Package for 32-bit versions ====Changes in launch parameters====Some parameters of the launch of Ubuntu: <tt>http://dl.torrentstreamsources and support nodes from the command line have been changed, therefore the launch with the old command line will not work.org/products/acestream-full/ubuntu/i368/latest</tt>

Package for 64-bit versions of UbuntuMain changes: * one executable file is used <tt>acestreamengine</tt>http; different launch modes (a source, support node) are set by options:** instead of <tt>acestreamengine-stream</tt> you should launch <tt>acestreamengine --stream-source</dl.torrentstream.orgtt>** instead of <tt>acestreamengine-node</productstt> you should launch <tt>acestreamengine --stream-node</acestreamtt>** instead of <tt>acestreamengine-client-fullconsole</ubuntutt> you should launch <tt>acestreamengine --client-console</amd64tt>** instead of <tt>acestreamengine-client-gtk</latesttt> you should launch <tt>acestreamengine --client-gtk</tt>* log system is changed. In old versions the engine output all debug information into STDERR and redirecting the output was required to write logs into a file. In a new version it is possible to define in options, where to write logs - into STDOUT, into STDERR, into a file or syslog. Rotation of logs by their size is supported for files. You can read description of all options in [[#acestreamengine command|acestreamengine command]]

Supported versions of Ubuntu: 11===acestreamengine command===Starting from version 2.101 Ace Stream Engine for Linux represents a single executable file <tt>acestreamengine</tt>, 12.04which works in different modes, 12depending on specified parameters.10

====Источник с встроенным трекеромSource with embedded tracker====Это наиболее простой способ запуск трансляции, не требующий запуска узлов поддержки и установки дополнительных трекеровThis is the easiest way to launch broadcast that does not require launching support nodes and installing additional trackers. Данный способ подходит для трансляций с небольшим количество пользователейThis method is suitable for broadcasts with a small number of users.

На сервере We launch the source on server 192.168.1.1 запускаем источник: <tt>acestreamengine--stream -source \

--title "Тестовая трансляцияTest broadcast" \

--add-authorized-peers \ > /tmp/test-source.log 2>&1</tt>

Последняя строка используется для записи логов в файл The last line is used to write logs into file /tmp/test-source.log. By default <tt>acestreamengine--stream-source</tt> выводит всю отладочную информацию на консоль в STDERRoutputs all debug information in the STDOUT.

Опция <tt>--add-authorized-peers</tt> добавляет в option adds the list of authorized nodes to acelive-файл список авторизованных узлов file (в данном случае это источникin this case, it's the source: 192.168.1.1).

После запуска трансляции в папке After broadcast's launch a file test.acelive will be created in directory /home/www/streams будет создан файл test.acelive, в папке in directory <tt>/tmp/streams</tt> будут созданы такие файлыsuch files will be created:*<tt>test</tt> - кэш трансляцииbroadcast cache. Размер этого файла примерно равен длительность_потока_в_секундах This file's size is approximately equal to stream_duration_in_seconds (опция <tt>--duration</tt>option, по умолчанию by default: 1 часhour) * битрейт байтbitrate byte*<tt>test.restart</tt> - здесь хранится информация для корректного перезапуска трансляцииinformation for correct restart of broadcast is kept here*<tt>test.sauth</tt> - ключ для цифровой подписи трансляцииkey for a broadcast's digital signature

Для просмотра трансляции клиенты могут скачать файл трансляции по ссылке To watch broadcasts clients can download broadcast file at <tt><nowiki>http://192.168.1.1/streams/test.acelive</nowiki></tt> и запустить его в плеере and start it in ACE Stream, либо использовать другие способы player or use other ways ([[Способы просмотра трансляцииWays to watch broadcasts]]).

====Источник с внешним трекеромSource with external tracker====Если трансляция предполагает большое количество пользователейIf broadcast involves a large number of users, то желательно использовать внешний трекер и отключить встроенный it's better to use external tracker and disable embedded one (для снижения нагрузки на источникto reduce burden on the source).

В качестве внешнего трекера мы советуем использовать We recommed to use [http://xbtt.sourceforge.net/tracker/ XBT Tracker]as external tracker.

В данном примере предполагаем, что In this example we assume that XBT Tracker установлен и запущен на сервере is installed and launched on server 192.168.1.1.Запуск трансляции теперь будет выглядеть таким образомNow broadcast's launch will look like: <tt>acestreamengine--stream -source \

--title "Тестовая трансляцияTest broadcast" \

--tracker "udp://192.168.1.1:2710/announce" \</tt> <tt> --skip-internal-tracker</tmp/testtt> option disconnects embedded tracker, <tt>--source.log 2>&1tracker</tt>option connects external tracker.

Опция <tt>--skip-internal-tracker</tt> отключает встроенный трекер====Source with two support nodes====If there is not enough upstream bandwidth for normal work of broadcast on the source, опция <tt>--tracker</tt> подключает внешний трекерsupport nodes can be used. Support node is often a node that receives data from the source and gives to clients (though support node can also receive data from other support nodes and even clients, depending on its settings). It makes sense to install support node on a separate server with a good width of output channel.

Для максимально эффективной работы схемы с узлами поддержки источнику необходимо сообщить адреса этих узлов с помощью опции <tt>--support-node</tt>: <tt>acestreamengine--stream -source \

--title "Тестовая трансляцияTest broadcast" \

--support-node "192.168.1.3:8621" \ > /tmp/test-source.log 2>&1</tt>

Запускаем узлы поддержки на серверах Launch support nodes on servers 192.168.1.2 и and 192.168.1.3 (команды для запуска одинаковыеcommands are the same): <tt>acestreamengine--stream-node \

--allow-source-download \ > /tmp/test-node.log 2>&1</tt>

Опция Option <tt>--source-node</tt> задает адрес источникаsets source address.

Опция Option <tt>--allow-source-download</tt> разрешает узлу поддержки скачивать данные с источника allows support node to download data from the source (скачивание с других узлов поддержки и клиентов в данном случае запрещеноdownloading from other support nodes and clients in this case is forbidden).

Если необходимо разрешить узлам поддержки скачивать данные с других узлов поддержкиTo allow support nodes to download data from other suppport nodes, то следует задать список других узлов опцией you should set a list of other nodes using <tt>--support-node</tt> и разрешить скачивание опцией option and allow downloading using <tt>--allow-support-download</tt>option.

На сервере On server 192.168.1.2 это будет выглядеть такit will look like: <tt>acestreamengine--stream-node \

--allow-support-download \ > /tmp/test-node.log 2>&1</tt>

На сервере On server 192.168.1.3: <tt>acestreamengine--stream-node \

--allow-support-download \ > /tmp/test-node.log 2>&1</tt>

====Приватный источник с двумя узлами поддержкиPrivate source with two support nodes====Иногда может возникнуть необходимость запретить клиентам напрямую обращаться к источнику трансляцииSometimes it may be necessary to prevent clients from direct access to broadcast source. НапримерFor example, источник может быть физически расположен на сервере в защищенной зоне без доступа из внешнего мираthe source may be located on server in protected area without access from the outer world. В этом случае трансляцию можно организовать по следующей схемеIn this case broadcast can be organized by the following scheme:*источник делается приватным the source is made private (получать от него данные смогут только узлы поддержкиonly support nodes, указанные явным образомspecified explicitly, can receive data from it)*узлы поддержки получают данные от источника и отдают клиентамsupport nodes receive data from the source and give to clients*клиенты получают данные от узлов поддержкиclients receive data from support nodes

Для того, чтобы сделать источник приватнымTo make the source private, следует указать опцию option <tt>--private-source</tt>must be specified: <tt>acestreamengine--stream -source \

--title "Тестовая трансляцияTest broadcast" \

--private-source \ > /tmp/test-source.log 2>&1</tt> Следует обратить внимание на то, что в данной конфигурации адрес трекера изменен на <tt>udp://192.168.1.2:2710/announce</tt>. Это сделано для поддержки старых версий клиентов, которые не обрабатывают список авторизованных пиров (подробнее здесь [[#Авторизованные узлы|Авторизованные узлы]]).

Узлы поддержки на серверах Notice that in this configuration tracker's address is changed to <tt>udp://192.168.1.2:2710/announce</tt>. It was made to support old versions of clients, which do not process a list of authorized peers (more details here [[#Authorized peers|Authorized peers]]).Launch support nodes on servers 192.168.1.2 и and 192.168.1.3 запускаем как обычноas usual: <tt>acestreamengine--stream-node \
