linux下用rtorrent挂pt,bt

在centos 6.2 64bit 下面安装rtorrent方法：

cd /etc/yum.repos.d
wget http://yum.aclub.net/pub/linux/centos/6/umask/umask.repo
rpm --import http://yum.aclub.net/pub/linux/centos/6/umask/RPM-GPG-KEY-umask
yum install rtorrent screen

在个人文件夹中，创建需要的目录

cd ~
mkdir watch # 用于存放.torrent文件
mkdir ptfiles # 用于存放下载的资料
mkdir session # 存放session

编写适用于本人的rtorrent配置文件

vim ~/.rtorrent.rc

写入

# This is an example resource file for rTorrent. Copy to
# ~/.rtorrent.rc and enable/modify the options as needed. Remember to
# uncomment the options you wish to enable.
# Maximum and minimum number of peers to connect to per torrent.
min_peers = 40
max_peers = 100
# Same as above but for seeding completed torrents (-1 = same as downloading)
min_peers_seed = 10
max_peers_seed = 50
# Maximum number of simultanious uploads per torrent.
max_uploads = 15
# Global upload and download rate in KiB. "0" for unlimited.
download_rate = 0
upload_rate = 0
# Default directory to save the downloaded torrents.
directory = ./ptfiles
# Default session directory. Make sure you don't run multiple instance
# of rtorrent using the same session directory. Perhaps using a
# relative path?
session = ./session
# Watch a directory for new torrents, and stop those that have been
# deleted.
schedule = watch_directory,5,5,load_start=./watch/*.torrent
schedule = untied_directory,5,5,stop_untied=
# Close torrents when diskspace is low.
schedule = low_diskspace,5,60,close_low_diskspace=100M
# The ip address reported to the tracker.
#ip = 127.0.0.1
#ip = rakshasa.no
# The ip address the listening socket and outgoing connections is
# bound to.
#bind = 127.0.0.1
#bind = rakshasa.no
# Port range to use for listening.
port_range = 6890-6999
# Start opening ports at a random position within the port range.
#port_random = no
# Check hash for finished torrents. Might be usefull until the bug is
# fixed that causes lack of diskspace not to be properly reported.
check_hash = yes
# Set whetever the client should try to connect to UDP trackers.
#use_udp_trackers = yes
# Alternative calls to bind and ip that should handle dynamic ip's.
#schedule = ip_tick,0,1800,ip=rakshasa
#schedule = bind_tick,0,1800,bind=rakshasa
# Encryption options, set to none (default) or any combination of the following:
# allow_incoming, try_outgoing, require, require_RC4, enable_retry, prefer_plaintext
#
# The example value allows incoming encrypted connections, starts unencrypted
# outgoing connections but retries with encryption if they fail, preferring
# plaintext to RC4 encryption after the encrypted handshake
#
# encryption = allow_incoming,enable_retry,prefer_plaintext
# Enable DHT support for trackerless torrents or when all trackers are down.
# May be set to "disable" (completely disable DHT), "off" (do not start DHT),
# "auto" (start and stop DHT as needed), or "on" (start DHT immediately).
# The default is "off". For DHT to work, a session directory must be defined.
#
dht = auto
# UDP port to use for DHT.
#
# dht_port = 6881
# Enable peer exchange (for torrents not marked private)
#
# peer_exchange = yes
#
# Do not modify the following parameters unless you know what you're doing.
#
# Hash read-ahead controls how many MB to request the kernel to read
# ahead. If the value is too low the disk may not be fully utilized,
# while if too high the kernel might not be able to keep the read
# pages in memory thus end up trashing.
#hash_read_ahead = 10
# Interval between attempts to check the hash, in milliseconds.
#hash_interval = 100
# Number of attempts to check the hash while using the mincore status,
# before forcing. Overworked systems might need lower values to get a
# decent hash checking rate.
#hash_max_tries = 10

到这里，rtorrent已经配置完成，为了端口正常使用，centos的iptables里需加:

iptables -A INPUT -p tcp --dport 6890:6900 -j ACCEPT
iptables -A INPUT -p udp --dport 6890 -j ACCEPT

rtorrent完全基于文本并在终端中运行，不可能每时每刻都开tty。所以，配合screen来，效果很好(screen -dmS name cmd )

 screen -dmS rtorrent-name rtorrent

在rtorrent的界面，常执行的操作是

Ctrl-s

Start download. Runs hash first unless already done. 定位到一个种子后，会先检查hash开始下载，一般是自动下载的

Ctrl-d

Stop an active download or remove a stopped download，按一次暂停，再按一次删除此任务及torrent文件(不会删除对应的下载文件)

a/s/d 增大下载速度限制分别为 1/5/50 KB.
z/x/c 减少下载速度限制分别为 1/5/50 KB.
A/S/D 增大上传速度限制分别为 1/5/50 KB.
Z/X/C 减少上传速度限制分别为 1/5/50 KB.

Ctrl-q

Quit application   退出rtorrent

官方文档

当正常下载之后，使用screen的如下组合键：

(ctrl + a ) +d

使当前screen会话detached，常用，简单的来说就是把rtorrent放入后台。
