Настройка домашнего сервера Linux (Часть 11)
Rtorrent
Для установки запустить:ipkg install rtorrentСоздать его рабочие директории:
mkdir -p /opt/torrents/dl mkdir -p /opt/torrents/downloaded mkdir -p /opt/torrents/sessionТак же нужно установить утилиту добавления пользователей:
ipkg install adduser
Далее создаем домашнюю директорию и пользователя под которым будет работать rtorrent:
mkdir -p /opt/home/p2p adduser --home /opt/home/p2p p2pПароль - ввести на усмотрение, он в дальнейшем не понадобится. Даем права вновь созданному пользователю:
chown p2p /opt/home/p2p chown p2p /opt/torrents/dl chown p2p /opt/torrents/downloaded chown p2p /opt/torrents/session chmod a+r /opt/etc/rtorrent.conf chmod a+x /opt/bin/rtorrentСоздаем файл запуска rtorrent:

При выполнении данного скрипта потребуются следующие пакеты: procps, grep, gawk и screen. Для их установки выполняем:ipkg install procps ipkg install grep ipkg install screen ipkg install gawkВ файл /opt/etc/profile добавить строчки для удобной работы в консоли rtorrent:
alias rt='su -c "screen -r" p2p' chmod a+rw `tty` stty start undef stty stop undefПосле изменения сохраняемся
flashfs save && flashfs commit && flashfs enableПроверяем результаты. Для начала убедиться, что пользователь завелся, и rtorrent под ним работает. Так:
su p2p /opt/bin/rtorrent -n -o import=/opt/etc/rtorrent.confТеперь нужно завершить ssh сессию. Это необходимо, чтобы написанное в файле profile вступило в действие.
9) Залогиниться снова. На всякий случай - mc не запускать!
Последовательно сказать
/opt/etc/init.d/S99rtorrent start rtЕсли консоль появилась - нажать:
ctrl + A ctrl + DГотово. Удалось отсоединится от консоли, но rtorrent продолжает работать. Убедиться, что в файле /usr/tmp/local/.files есть следующие строчки:
/etc/passwd /etc/groupПри необходимости отредактировать выполнить.
flashfs save && flashfs commit && flashfs enableЕсли этого не сделать (или, например, если в /usr/tmp/local/.files будут отсутствовать строчки /etc/passwd и /etc/group) то только что заведенный пользователь при перезагрузке исчезнет. Не забыть отредактировать файл конфигурации rtorrent под себя:
vi /opt/etc/rtorrent.confТак же нужно добавить следующую строчку в конфиг:
system.method.set_key = event.download.erased,rm_complete,"execute=rm,-rf,--,$d.get_base_path="Она позволяет удалять загруженные файлы если из интерфейса удален торент.

vi /usr/local/sbin/post-firewallИсходя из текущего конфига нужно открыть порты с 51777 по 51780 и 6881, добавляем в файл следующие стоки:
#!/bin/sh iptables -I INPUT -p tcp --dport 51777:51780 -j ACCEPT iptables -I INPUT -p tcp --dport 6881 -j ACCEPTТеперь можно перезагрузиться:
flashfs save && flashfs commit && flashfs enable && reboot
