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;

使用Tampermonkey油猴脚本自动抢购斯巴达spartanhost vps

发布时间：March 1, 2021 // 分类： // 3 Comments

最近斯巴达vps比较火，一机难求，写了个js脚本用于抢购，效果还不错，推荐使用chrome浏览器，安装Tampermonkey扩展使用。

// ==UserScript==
// @name         自动抢购买vps

(function() {
    var forcedReload = false;
    var time = 500; 
    var url = document.URL;
    var hostname = "www.haiyun.me";
    var customfield = "website";
    if (document.title == '502 Bad Gateway') {
        setTimeout(function() {
            window.location.reload(forcedReload);
        }, time);
    } else if (document.title == '504 Gateway Time-out') {
        setTimeout(function() {
            window.location.reload(forcedReload);
        }, time);
    } else if (document.title == '503 Service Temporarily Unavailable') {
        setTimeout(function() {
            window.location.reload(forcedReload);
        }, time);
    } else if (document.title == '500 Internal Server Error') {

        setTimeout(function() {
            window.location.reload(forcedReload);
        }, time);
    }

    if (url.indexOf("https://billing.spartanhost.net/cart.php?a=add") != -1) {
        var str = document.getElementById("order-boxes").innerHTML;
        if (str.indexOf("Out of Stock") != -1) {

windows10添加多ip地址及指定出口ip

发布时间：February 24, 2021 // 分类： // No Comments

查看网卡名称及编号：

netsh int ipv4 show int

查看当前ip地址：

netsh int ipv4 show ipadd level=verbose

开启dhcp和静态ip共存：

netsh int ipv4 set int "Ethernet0" dhcpstaticipcoexistence=enabled

添加ip地址，skipassource设置是否使用此ip为出口源ip，默认新添加的ip为出口ip：

netsh int ipv4 add add "Ethernet0" 192.168.1.22/24 skipassource=true

已添加的ip修改skipassource参数：

Get-NetIPAddress 192.168.1.22 | Set-NetIPAddress -SkipAsSource $True
Set-NetIPAddress -IPAddress "192.168.1.22" -InterfaceAlias "Ethernet0" -SkipAsSource $false

多网卡可修改路由及网卡metric跃点数指定优先网络出口：

netsh int ipv4 show rou
netsh int ipv4 set int "Ethernet0" metric=2
netsh int ipv4 set rou 0.0.0.0/0 "Ethernet0" 192.168.1.1 metric=100
route change 0.0.0.0 mask 0.0.0.0 192.168.1.1 metric 100 if 4

n1盒子连接手机4G无线热点做k2p宽带pppoe备份线路并切换

发布时间：February 24, 2021 // 分类：N1,K2P // No Comments

k2p主路由地址：192.168.1.1
n1盒子地址：192.168.1.2
k2p添加低优先级默认路由走n1，此路由只有pppoe断开后才有效：

ip rou add default via 192.168.1.2 dev br-lan metric 1000

n1盒子用netplan配置无线网络默认路由和无线热点的路由优先级，默认情况下走k2p主路由，当路由器pppoe不能连接时打开手机无线热点则自动走手机4g网络连接。

n1盒子开启snat及网络转发：

iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
sysctl -w net.ipv4.ip_forward=1
