    TRANSFERENCIA O DISTRIBUCIÓN DE ARCHIVOS ENTRE IGUALES (peer-to-peer) Características, Protocolos, Software, Luis Villalta Márquez Configuración Peer-to-peer Una red peer-to-peer, red de pares, red entre iguales, red entre pares o red punto a punto (P2P, por sus siglas en inglés) es una red de computadoras en la que todos o algunos aspectos funcionan sin clientes ni servidores fijos, sino una serie de nodos que se comportan como iguales entre sí. Es decir, actúan simultáneamente como clientes y servidores respecto a los demás nodos de la red. Las redes P2P permiten el intercambio directo de información, en cualquier formato, entre los ordenadores interconectados. Peer-to-peer Normalmente este tipo de redes se implementan como redes superpuestas construidas en la capa de aplicación de redes públicas como Internet. El hecho de que sirvan para compartir e intercambiar información de forma directa entre dos o más usuarios ha propiciado que parte de los usuarios lo utilicen para intercambiar archivos cuyo contenido está sujeto a las leyes de copyright, lo que ha generado una gran polémica entre defensores y detractores de estos sistemas. Las redes peer-to-peer aprovechan, administran y optimizan el uso del ancho de banda de los demás usuarios de la red por medio de la conectividad entre los mismos, y obtienen así más rendimiento en las conexiones y transferencias que con algunos métodos centralizados convencionales, donde una cantidad relativamente pequeña de servidores provee el total del ancho de banda y recursos compartidos para un servicio o aplicación. Peer-to-peer Dichas redes son útiles para diversos propósitos.

    Установка И Настройка Rtorrent+Rutorrent+Nginx+Php-Fpm В Arch Linux 1 / 9

    УСТАНОВКА И НАСТРОЙКА RTORRENT+RUTORRENT+NGINX+PHP-FPM В ARCH LINUX 1 / 9 Установка и настройка rtorrent+rutorrent+nginx+php-fpm в Arch Linux Предыстория Для работы с торрентами я достаточно долго использовал ktorrent. Сей клиент мои потребности в удобном управлении закачками удовлетворял полностью, пока я не заметил, что на популярных торрентах загрузка процессора доходила до 50% (а с uTP — ещё больше), а потребление памяти в и без того жирном KDE стало неприятно бросаться в глаза. Было решено сменить KDE на xfce (это отдельная история), а программу для торрентов подобрать с хорошим функционалом и удобным управлением. Перепробовав transmission, deluge и rtorrent, я остановлися на последнем. О том, как настроить rtorrent+rutorrent+nginx+php-fpm, и будет под катом. Почему так? Сразу хочу ответить, почему выбраны именно означенные инструменты. Arch Linux. Об этом дистрибутиве можно говорить достаточно долго, мне нравится его организация и философия в целом, и я могу его использовать для себя с максимальной эффективностью. Кому интересно более детально прочитать о нём, смотрите сюда и сюда. nginx. Я впечатлён тем, как эта маленькая штука выполняет свою работу, экономя память, гибко настраиваясь и предоставляя весь необходимый мне функционал. php-fpm. Можно настроить количество рабочих потоков, в связке с nginx даёт Linux для всех УСТАНОВКА И НАСТРОЙКА RTORRENT+RUTORRENT+NGINX+PHP-FPM В ARCH LINUX 2 / 9 замечательную производительность. rtorrent. Малое потребление ресурсов, хорошо настраивается. rutorrent. Активно развивается, имеет приятный интерфейс. Установка необходимого программного обеспечения Будем исходить из того, что Arch Linux на компьютере уже стоит, а пользователь знаком с его пакетной системой. Чтобы установить веб-часть связки, выполняем команду: sudo pacman -S nginx php-fpm rtorrent и librtorrent я рекомендую устанавливать с AUR'а, там есть замечательный PKGBUILD под названием rtorrent-color, делающий скучный консольный интерфейс более приятным (если будете им пользоваться), и libtorrent-extended, имеющий дополнительные патчи.
