Il Torrent pare oramai il protocollo più diffuso per la condivisione di contenuti, ma il castello di carte che si regge sulla condivisione va aiutato,  così da diverso tempo dedico il mio vecchio raspberry Pi B+ 1 (512Mb ram) alla condivisione, iso e poche altre cose compreso un paio di titoli introvabili.

Perché rtorrent ?

Perché è installato su un raspberry PI B e necessita di poche risorse, è tra i più potenti, ha un’interfaccia minimalista da console che convive ottimamente in una scheda di tmux perché rtorrent resta uno dei migliori .

Con il passaggio a buster sulla rasbian abbiamo trovato tra le novità una nuova versione di rtorrent, la 0.9.7, molto aggiornata ma con il bisogno di un nuovo file rtorrent.rc di configurazione.

A detta dello stesso sviluppatore occorre un nuovo template (e qui ne trovate uno valido), perché quello della precedente versione è “vecchia spazzatura“.

a modern rTorrent configuration that provides a good starting point. Its expressed purpose is to replace that years-old rotting piece of garbage that people still use to create their first configuration. Friends don’t let friends use that!

rtorrent

installare rtorrent è semplice perché è già disponibile nei repository ufficiali e ha poche dipendenze.

# apt install rtorrent

configurazione con .rtorrent.rc

successivamente va creato un file di configurazione nella nostra /home con il nome .rtorrent.rc , come spunto ho usato il template ufficiale a cui ho apportato alcune modifiche e ripulito del non necessario.

Per ottimizzare le prestazioni potete seguire questa guida, oppure consultare in generale la guida di configurazione per saziare ogni vostro dubbio.
