迈拓Seagate MSS II NAS攻略大法之rtorrent篇
rtorrent介绍本来我打算就在mss上装mldonkey，这个软件既可以BT，又可以电驴，不过我装上这个软件后，发现很多BT的种子无法下载。现在下载电影什么基本还是bt，所以我就只能装rtorrent专门BT下载。
在mss上能跑的BT软件不少，不过应该这个是最好的，功能最全，支持不少新的功能。bt的下载速度可以达到windows的水平。
类似的软件，其实都有一个共同的特点，你可以通过web去控制，也可以通过windows的专门的客户端去控制。这两种方式你都可以实现远程控制，监控bt的下载。
关于乱码，我刚发现原来mss上自带的samba，就是3.02，你可以在命令行下查看，我这里就是在命令行下是乱码，在windows看到的都是正常，看来在mss上配置应该比在ddwrt等上配置简单不少。
# /usr/local/samba/sbin/smbd -V
Version 3.0.2
安装rtorrent 和相关软件
ipkg update
ipkg instal rtorrent
ipkg install screen
ipkg install lighttpd
ipkg install openldap-libs
mkdir /opt/share/torrent/session
# ln -s /opt/share/torrent/ /shares/mss-hdd/Public/downloads/
备注
1：缺省的下载路径是/opt/share/torrent/，我没有修改他的路径，只是做了一个链接，由于/opt/share/torrent/ 下缺少session文件夹，所以我创建一个。
2：如果不安装openldap-libs，你启动lighttpd会报错，可以参考底下的详细说明
配置rtorrent.conf 文件
当你装完rtorrent后，就会在/opt/etc/rtorrent.conf ，这是rtorrent的配置文件，我们需要修改这个文件，并把这个文件复制到/opt/root 目录下，并改名为.rtorrent.rc 。有一点需要注意的，在linux下修改配置文件，最好都是先做备份。
运行下面的命令
cd /
cp /opt/etc/rtorrent.conf /opt/etc/rtorrent.conf_backup
cp /opt/etc/rtorrent.conf /opt/root/.rtorrent.rc
vi /opt/root/.rtorrent.rc
编辑.rtorrent.rc ，下面是我的配置文件的全部内容
# 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.
# Minumum amount of peers to connect per torrent, if available.
min_peers = 40
# Minumum amount of peers to connect per torrent.
max_peers = 250
# Same as above but for seeding completed torrents (-1 = same as downloading)
#min_peers_seed = 10
#max_peers_seed = 20
# Maximum number of simultanious uploads per torrent.
max_uploads = 15
# Global download rate in KiB. "0" for unlimited.
download_rate = 200
# Global upload rate in KiB. "0" for unlimited.
upload_rate = 30
# Default directory to save downloaded files. Note it doesn't support
# space yet.
directory = /opt/share/torrent/work/
# Watch a directory for new torrents, and stop those that have been deleted.
schedule = watch_directory,5,5,load_start=/opt/share/torrent/dl/*.torrent
schedule = untied_directory,5,5,stop_untied=
# Close torrents when diskspace is low.
#schedule = low_diskspace,5,60,close_low_diskspace=100M
# Default session directory. Make sure you don't run multiple instance
# of rtorrent using the same session directory. Perhaps using a
# relative path?
session = /opt/share/torrent/session
# The ip address reported to the tracker.
#ip = rakshasa
# The ip address the listening socket and outgoing connections is
# bound to.
#bind = rakshasa
# 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 = no
# 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
#
# 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
# Max number of files to keep open simultaniously.
#max_open_files = 128
# Number of sockets to simultaneously keep open.
#max_open_sockets = <no default>
# Example of scheduling commands: Switch between two ip's every 5
# seconds.
#schedule = "ip_tick1,5,10,ip=torretta"
#schedule = "ip_tick2,10,10,ip=lampedusa"
# Remove a scheduled event.
#schedule_remove = "ip_tick1"
# Stop torrents when reaching upload ratio in percent,
# when also reaching total upload in bytes, or when
# reaching final upload ratio in percent.
# example: stop at ratio 2.0 with at least 200 MB uploaded, or else ratio 20.0
#schedule = ratio,60,60,"stop_on_ratio=200,200M,2000"
schedule = ratio,30,60,stop_on_ratio=200
# 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 = on
# UDP port to use for DHT.
#
dht_port = 6778
# Enable peer exchange (for torrents not marked private)
#
peer_exchange = yes
#
# Do not modify the following parameters unless you know what you're doing.

修改lighttpd.conf文件
vi /opt/etc/lighttpd/lighttpd.conf
首先在server.modules中加入一行
server.modules = (
# "mod_rewrite",
# "mod_redirect",
# "mod_alias",
"mod_access",
# "mod_cml",
# "mod_trigger_b4_dl",
# "mod_auth",
# "mod_status",
# "mod_setenv",
# "mod_fastcgi",
# "mod_proxy",
# "mod_simple_vhost",
# "mod_evhost",
# "mod_userdir",
# "mod_cgi",
# "mod_compress",
# "mod_ssi",
# "mod_usertrack",
# "mod_expire",
# "mod_secdownload",
# "mod_rrdtool",
"mod_accesslog",
"mod_scgi")
注意红色就是添加的。
在lighttpd.conf的最后加上
################
scgi.server = (
"/RPC2" =>
( "127.0.0.1" =>
(
"host" => "127.0.0.1",
"port" => 5000,
"check-local" => "disable"
)
)
)

运行rtorrent
这个时候，你就可以在telnet到mss上运行直接运行rtorrent，不过有一点需要注意的，如果你关闭telnet的窗口，那么rtorrent也就停止了。所有你需要screen这个软件。
screen是个窗口管理器，在screen中运行的程序可以进入后台运行（进入后台后就可以关闭telnet，但是程序仍然在运行），并且可以随时调回前台，所以玩路由器或NAS的这个工具是必须要掌握的，非常有用哦！！
使用screen
在telnet中输入screen回车，将看到一大堆英文，这个时候再按一次回车，将进入一个新的screen窗口我简称之为窗口1，此时运行你想要的程序例如rtorrent，然后按Ctrl+A，D(这个代表按住Ctrl不放按A，然后松开手按D)，就能使这个screen窗口1进入后台运行，这个时候即使关了telnet都是可以的，rtorrent仍然在后台运行，以后如果我想再回到窗口1，只要重新telnet连上路由，运行screen -r即可，你就又回到了窗口1了，用类似的方法你还可以开启窗口2，窗口3等等，这里就不介绍了，如果你有兴趣可以google搜索“linux screen 用法”
我们只要用screen将rtorrent放入后台运行，然后往监视目录中放种子文件就能完成下载，非常轻松哦，要查看状态，就telnet连上路由，然后screen -r即可，最高效的用法！！
重启服务
重启rtorrent和lighttpd
/opt/etc/init.d/S80lighttpd stop
/opt/etc/init.d/S80lighttpd start
killall rtorrent
启动rtorrent，就要用screen来启动
rtorrent
开机启动rtorrent
编辑/opt/etc/init.d/S99local
添加下面这一行就可以，
/opt/bin/screen -d -m /opt/bin/rtorrent -n -o import=/opt/root/.rtorrent.rc
在windows上安装rtorrent客户端管理程序
http://ntorrent.googlecode.com/f ... in-0.5-beta-win.zip
现在是这个版本了。下载回来后，运行ntorrent，
（可能是我机器已经安装java运行库，没有提示需要这个。
protocol : http/ssh
host : MSS的IP
port : 8081 (可以在/opt/etc/lighttpd/lighttpd.conf中修改成其他的，默认是这个)
mountpoint : /RPC2
最底下用户名和密码不填(如果你选择ssh，那么你就需要输入root的用户名和密码），点save然后点connect，如果能连上就可以使用ntorrent远程控制了
修改文件夹的权限
我通过链接的方式，把torrent的文件夹链接的到public的文件夹下，省去了修改配置文件里路径。不过产生了一个新的文件，就是这些文件夹，你在windows下，无法删除和写入文件，原因就和linux的权限有关。
解决的办法两个
1：修改配置文件，把路径指向public的文件夹，你在windows下，在public下建立相应的文件夹。
2：就是修改文件夹的权限，你可以通过winscp登陆mss，把torrent下的文件夹的权限有0755，全部都改为0777。这样就可以了，linux下用命令 chmod 777 目录。
备份配置文件
linux的配置，其实就是修改配置文件，把运行良好的配置文件备份下来，以后安装调试就好办多了。我的习惯是在/public/downloads/mss/config 把所有的配置文件都放在这个文件夹下。
# cp /opt/root/.rtorrent.rc /shares/mss-hdd/Public/downloads/mss/config/backup.rtorrent.rc
# cp /opt/etc/lighttpd/lighttpd.conf /shares/mss-hdd/Public/downloads/mss/config/backup.lighttpd.conf
# cp /opt/etc/vsftpd.user_list /shares/mss-hdd/Public/downloads/mss/config/backup.vsftpd.user_list
# cp /opt/etc/init.d/S99local //shares/mss-hdd/Public/downloads/mss/config/backup.S99local
要注意的问题
1：下载的路径，缺省都是指向/opt/share/torrent, 我没有修改他的路径，而且通过link的命令，做了一个链接，链接到public/downloads 目录下，我觉得这样会更加简单些。
2：这个配置文件是我目前用的配置文件，我是2m的adsl，大家可以参考，详细的解析，大家可以看恩山论坛，我是参考那里修改的，但是有个地方不太一样，scgi_port = localhost:5000，这个是和客户端远程管理相关，我使用恩山论坛的参数会出现这个错误：the response could not be parsed
3：lighttpd这个文件的修改，我也是和恩山论坛的那个贴有点不太一样的，就是后面增加的部分。
4：rotrrent还有一个功能，你可以把bt的文件直接放到rtorrent的目录下，他就会自动下载。
5：要提高下载速度，还必须在router里做端口映射，具体的端口，就是在配置文件里指定的，port_range = 6890-6999
6：rtorrent的远程管理其实可以不安装lighttpd，通过ssh进行远程连接，因为我们本身就安装了dropbear，所以你设置rtorrent通过ssh远程连接就可以了，我已经测试过，没有问题。
7：关于乱码的问题，目前我这里只是telnet上去运行rtorrent出现乱码，在windows下访问共享都是正常的，在客户端上也是正常的。这个估计和mss自带的samba就是3.02.
8：通过screen，可以在后台运行，如果mss重新启动，那么还是需要登陆mss上运行rtorrent，开机就启动rtorrent，开始下载的方案是：修改S99local，添加一行
/opt/bin/screen -d -m /opt/bin/rtorrent -n -o import=/opt/root/.rtorrent.rc
8：lighttpd这个是用来做rtorrent管理用的，装这个的时候会出现下面的错误
tarting web server: lighttpd
2008-04-08 09:58:55: (plugin.c.165) dlopen() failed for: /opt/lib/lighttpd/mod_auth.so File not found
2008-04-08 09:58:55: (server.c.622) loading plugins finally failed

这个错误的解决办法就是你需要再安装一个包就可以解决了

这个时候，你启动lighttpd，就没有问题了
9：我装完rtorrent，我所安装的软件，这些软件一部分是我安装的，一部分是optware里带的。下次记录一下optware里的软件，这样就可以知道系统装了多少软件了。经常出现不同的报错，很多情况下都是因为你的环境不太一样。
