发布时间:March 5, 2021 // 分类:PT // No Comments

torrent解析类使用https://github.com/Rhilip/Bencode,打补丁支持获取种子hash信息。

解析种子torrent所包含的文件名称信息,将名称和文件大小组合排序并计算sha,sha相同则2个种子内容一样可自动辅种。

<?php
require_once './Bencode.php';
require_once './ParseErrorException.php';
$bencode = new Bencode(); 
$str = file_get_contents($filename);
$s = $bencode->decode($str);

if (isset($s['info']["files"])) {
  foreach ($s['info']["files"] as $v) {
    $length = $v["length"];
    $file = end($v["path"]);
    $save[] = $length.$file;
  }
} else {
  $length = $s['info']["length"];
  $file = $s['info']["name"];
  $save[] = $length.$file;

  $coding = mb_detect_encoding(implode('', $save), ['UTF-8', 'GB18030', 'GBK', 'GB2312', 'ISO-8859-1']);
  echo 'detect encoding: '.$coding.PHP_EOL;
}
if (!$coding) {
  $coding = 'UTF-8';
}
if ($coding != "UTF-8") {
  foreach ($save as $k => $v) {

N1用transmission刷PT自动挂载移动硬盘配置问题

发布时间:March 2, 2019 // 分类:PT,N1 // No Comments

挂载移动硬盘fstab配置文件,nofail当移动硬盘没插入时不提示错误,要不然提示错误进不去系统,noatime提升硬盘文件系统性能

/dev/sda1       /mnt            ext4            defaults,nofail,noatime,errors=remount-ro       0 2

配置transmission当移动硬盘挂载后才开始启动,且启动前检查下载目录是否存在,否则启动失败。

查看system生成的移动硬盘挂载服务,然后配置transmission在其挂载之后启动。

systemctl list-unit-files |grep -i mount|grep mnt
mnt.mount                                  generated      

transmission service配置:

[Unit]
Description=Transmission BitTorrent Daemon
After=network.target mnt.mount 

[Service]
LimitNOFILE=65535
User=debian-transmission
#Type=notify
Type=simple

ubuntu18.04编译使用transmission2.92/2.94/3.0跳过校验

发布时间:November 16, 2018 // 分类:PT // No Comments

安装编译环境及transmission依赖:

apt-get install ca-certificates libcurl4-openssl-dev libssl-dev pkg-config build-essential checkinstall libevent-dev intltool libtool zlib1g-dev

下载编译transmission:

wget http://archive.ubuntu.com/ubuntu/pool/main/t/transmission/transmission_2.92.orig.tar.gz
tar zxvf transmission_2.92.orig.tar.gz 
cd transmission-2.92
wget http://archive.ubuntu.com/ubuntu/pool/main/t/transmission/transmission_2.92-3ubuntu2.debian.tar.xz
tar Jxvf transmission_2.92-3ubuntu2.debian.tar.xz

wget https://github.com/superlukia/transmission-2.92_skiphashcheck/commit/56e327d1dacb5b3453954b76a6d0edd30edb7a34.patch
patch -p 1 < 56e327d1dacb5b3453954b76a6d0edd30edb7a34.patch
./configure 
make 
#替换已安装的transmission-daemon
mv /usr/bin/transmission-daemon /usr/bin/transmission-daemon.bak
cp daemon/transmission-daemon /usr/bin/transmission-daemon

2.94:

apt-get source transmission-daemon
#tar zxf transmission_2.94.orig.tar.gz transmission-2.94/
cd transmission-2.94/
wget https://github.com/blackyau/Transmission_SkipHashChek/commit/0a18e4dffc7002eb80abe39ae8c8c8aec1205967.patch
git apply 0a18e4dffc7002eb80abe39ae8c8c8aec1205967.patch
./autogen.sh
make

3.0:

apt install git ca-certificates libcurl4-openssl-dev libssl-dev pkg-config build-essential checkinstall libevent-dev intltool libtool zlib1g-dev libglib2.0-dev libsystemd-dev
git clone https://github.com/transmission/transmission
cd transmission/
git checkout 3.00
git submodule update --init
git clone https://github.com/TonyRL/docker-transmission-skip-hash-check.git
patch -p0 < docker-transmission-skip-hash-check/patches/001-skip-hash-checking.patch 
patch -p0 < docker-transmission-skip-hash-check/patches/002-fdlimit.patch 
patch -p0 < docker-transmission-skip-hash-check/patches/003-random-announce.patch 
./autogen.sh --prefix=/usr/local/transmission --with-systemd 
make && make install

如果编译时没安装libsystemd依赖,需修改下systemd服务,不然通过systemctl启动transmission会卡住。

cat /etc/systemd/system/multi-user.target.wants/transmission-daemon.service
[Unit]
Description=Transmission BitTorrent Daemon

ExecStop=/bin/kill -s STOP $MAINPID
