<title>记一次阿里云配置 PPTPd，及 IPTables Log 调试</title>
<url>/2016/08/11/aliyun-pptp-writeup-and-iptables-using-logs/</url>
<content><![CDATA[<p>虽然爬墙主用 SS， 但是对于全局或非 TCP 协议的时候，SS 还是显得有些不足。</p>
<p>配置 PPTP 应该是很多 FQer 第一个接触的方法，也是比较古老的方法，由于加密不足以及流量特征被 GFW 捕获，使用率降低。</p>
<p>今天<del datetime="2016-08-11T09:55:56+00:00">吃多了</del>由于需要全局，就在Aliyun上重现一下配置过程。途中遇到了不少坑，谨作为记录</p>
<span id="more"></span>
<h3 id="PPTPd"><a href="#PPTPd" class="headerlink" title="PPTPd"></a>PPTPd</h3><h4 id="yum-安装-pptpd-软件包"><a href="#yum-安装-pptpd-软件包" class="headerlink" title="yum 安装 pptpd 软件包"></a>yum 安装 pptpd 软件包</h4><figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">yum install pptpd</span><br></pre></td></tr></table></figure>

<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">vi /etc/pptpd.conf</span><br></pre></td></tr></table></figure>
<p>在这个文件里主要就是对 localip 以及 remoteip 的配置，去掉注释并修改为希望的地址段，简单了说就是一个地址池，拨入的用户会从 remoteip 段中<del datetime="2016-08-11T09:55:56+00:00">分配</del>获得一个地址，而 localip 即是本机在 ppp 连接后的地址<br><img data-src="/images/posts/2016/08/QQ20160811-5.png" alt="QQ20160811-5"></p>
</blockquote>
<h5 id="Options"><a href="#Options" class="headerlink" title="Options"></a>Options</h5><blockquote>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">vi /etc/ppp/options.pptpd</span><br></pre></td></tr></table></figure>
<p>这个文件中需要修改的就是 DNS 地址了，去掉注释并修改 ms-dns 的值，这里为什么修改成这个地址下面会讲，各位按照实际情况修改。<br>当然是用的协议标准也在这里，MPPE等，如若协议出错可修改。默认标准可不进行修改<br><img data-src="/images/posts/2016/08/QQ20160811-3.png" alt="QQ20160811-3"></p>
</blockquote>
<h5 id="Secrets"><a href="#Secrets" class="headerlink" title="Secrets"></a>Secrets</h5><blockquote>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">vi /etc/ppp/chap-secrets</span><br></pre></td></tr></table></figure>
<p>由于不需要复杂认证，就在这里填写连接用用户名密码，格式为：用户名 pptpd 密码 <em>，最后的那个</em>为分配的 IP，指定 IP 的话，可以配合 iptables SNAT 至不同地址，实现多用户不同 IP（理论，未验证）</p>
</blockquote>
<h5 id="Sysctl"><a href="#Sysctl" class="headerlink" title="Sysctl"></a>Sysctl</h5><blockquote>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">vi /etc/sysctl.conf</span><br></pre></td></tr></table></figure>
<p>此处修改系统规则，修改 net.ipv4.ip_forward 项值为 1，启用 ip 转发？<br>如若存在 net.ipv4.tcp_syncookies 项目，请注释。<br><img data-src="/images/posts/2016/08/QQ20160811-6.png" alt="QQ20160811-6"><br>使修改生效 ```bash<br>sysctl -p</p>
</blockquote>
<figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line"></span><br><span class="line">#### 启动 pptpd</span><br><span class="line">```bash</span><br><span class="line">systemctl restart pptpd</span><br></pre></td></tr></table></figure>

<p>添加如下两行至适当位置：</p>
<figure class="highlight plaintext"><table><tr><td class="code"><pre><span class="line">-A INPUT -p gre -j ACCEPT</span><br><span class="line">-A INPUT -p tcp -m state --state NEW -m tcp --dport 1723 -j ACCEPT</span><br></pre></td></tr></table></figure>
<p>其中第一行是放通 GRE 连接，第二行放通 1723端口 TCP 连接<br><img data-src="/images/posts/2016/08/QQ20160811-7.png" alt="QQ20160811-7"></p>

<title>使用 CentOS 实现小型网络路由 - 基础服务</title>
<url>/2016/11/24/centos-based-router-base-configuation/</url>
<content><![CDATA[<p>前些时间入手 Gen8 一台，这东西作为家用虚拟化平台是不错的选择。作为一开始的设想，是想将它唯一的 PCI-e 用来插显卡，配合 VT-d 技术直通入虚拟机，而在 ESXi 上跑别的服务。那么，首先需要一个可靠的路由来做外网 NAT，于是就有了这篇。</p>
<span id="more"></span>
<p>关于软路由系统的选择，参考了<span class="exturl" data-url="aHR0cHM6Ly9lbi53aWtpcGVkaWEub3JnL3dpa2kvTGlzdF9vZl9yb3V0ZXJfYW5kX2ZpcmV3YWxsX2Rpc3RyaWJ1dGlvbnM=">这篇 WIKI<i class="fa fa-external-link-alt"></i></span>。<br>首先并不是很喜欢使用普遍路由中使用的 DD-WRT or OpenWrt，DD 是因为功能不满足需求，而 OpenWrt 直到 15.05 才有官方的 x86-64，暂且不论兼容性，有许多包在 64 位需要自己编译，并且最新版的 OpenWrt 移除了 14.x 中的 oldpackages，导致 pdnsd 也没了。一直在使用的 RouterOS 配置简明，但是在 x86 上表现一般，且没有第三方的包（没有 VMXNET3 驱动），后来选择了 VyOS（前身Vyatta），看中的就是这玩意带一个类似硬路由的 shell，可惜使用时由于其官方 community 源 404，还是 pass 了。</p>
<p>想来 Linux 用起比较顺手，就干脆用它来用作路由。看了一圈最后还是选了 CentOS，虽然其官方文档惨不忍睹，但是有 RHEL 这个老爹在，光是网络部分的文档就有 12 章之多，<span class="exturl" data-url="aHR0cHM6Ly9hY2Nlc3MucmVkaGF0LmNvbS9kb2N1bWVudGF0aW9uL2VuLVVTL1JlZF9IYXRfRW50ZXJwcmlzZV9MaW51eC83L2h0bWwvTmV0d29ya2luZ19HdWlkZS9jaC1JbnRyb2R1Y3Rpb25fdG9fUkhFTF9OZXR3b3JraW5nLmh0bWw=">RHEL 文档地址<i class="fa fa-external-link-alt"></i></span>。</p>

<title>在Mac上安装Fish</title>
<url>/2015/07/31/fish-on-macos/</url>
<content><![CDATA[<p>一直在Mac上用着自带的zsh，配合oh-my-zsh使用体验还算不错，主题也能定制很强大，</p>
<p>但是近日一个大牛给我推荐fish，也厌倦了bash的繁琐，于是乎。。手痒了</p>
<span id="more"></span>
<p>首先得说，有了brew这个神器，Mac真的是Shell和GUI的完美结合。</p>

<p>这时已经可以直接输入/usr/local/bin/fish体验了</p>

<p>我们添加一行/usr/local/bin/fish</p>

<title>MotoBlur On Milestone v0.1a ! 115网盘地址更新~</title>
<url>/2010/08/19/motoblur-on-milestone/</url>
<content><![CDATA[<p><span style="line-height: normal; -webkit-border-horizontal-spacing: 2px; -webkit-border-vertical-spacing: 2px; font-size: small;"><strong>[v0.1a][21-08-2010] MotoBlur for Milestone</strong></span></p>
<p>I have now more success with the Froyo 2.2 MotoBlur port to milestone but it required a more technical approach than just lib replacements here..<br>Partly because Verizon put some policies on Motorola to put it into the firmware, and partly because it required different audio handling.</p>
<p>Most features seen in MotoFrenzy is also shared here. both good and bad ones. Battery wise this image offers utilities to manage wifi inactivity and battery training policies.</p>
<p>I feel that the features found in the MotoBlur, justify a more proper release, than initially, as Battery management and scalable widgets seems like nice features to me.</p>
<p><span style="font-size: small;">Download Mirror 1<span class="exturl" data-url="aHR0cDovL3JhcGlkc2hhcmUuY29tL2ZpbGVzLzQxNDEyNDI1MC9Nb3RvQmx1ci56aXAuaHRtbA==">MotoBlur v0.1 full image<i class="fa fa-external-link-alt"></i></span></span><br><span style="font-size: small;">Download Mirror 2<span class="exturl" data-url="aHR0cDovL2RleHQzci5rb21vZGluLm9yZy9Nb3RvQmx1ci56aXA=">MotoBlur v0.1 full image<i class="fa fa-external-link-alt"></i></span></span> (Thanks to klash for the mirror)</p>

<p>You can use G.O.T recovery for installation of the image (i read latest OpenRecovery is no longer compatible)</p>
<p>Copy the included MotoBlur folder onto your sdcard</p>

<h2 id="First-time-install-information"><a href="#First-time-install-information" class="headerlink" title="First time install information"></a><strong>First time install information</strong></h2><blockquote>
<ul>
<li><p>Recommended is to remove your SIM card the first time you start up, as the card activation process during setup with a non-Verizon card fails and takes datatraffic and is slow, if you got a card in your phone. Take it out, and you are quickly offered the option to setup later.</p>
</li>
<li><p>G.O.T recovery should offer your the option to partition your SDCARD if you wish to use a ext2 sdcard partition for apps2sd functionality.</p>
</li>
<li><p>Overclock included, means you can take the sample “overclock” file from the .zip and copy to your SDCARD, and it will be activated at bootup. you can modify content of the overclock file, but you need to find details on parameters on the authors webpage <span class="exturl" data-url="aHR0cDovL2NvZGUuZ29vZ2xlLmNvbS9wL21pbGVzdG9uZS1vdmVyY2xvY2s=">here<i class="fa fa-external-link-alt"></i></span>.</p>

<p><strong>Based on release version 2.2.90 of Droid2 firmware found.</strong></p>
<p>Battery manager offers 5,10,15,30 minutes timeout for data connection now. (original was 15,30,45,60)</p>
<p>GPS is a drawback for now, as Motorola started using new communication methods between their drivers on CDMA based firmwares.</p>
<p>Fully deodex’d rom (requires little more memory, but is sufficient in Motorola phone environment)</p>
<ul>
<li>It should noted, that Droid2 comes with 512MB RAM, which might for more hours become an issue on milestone, if froyo2.2 memory management handles this badly.</li>

<title>搭建私人 Ngrok 转发通道</title>
<url>/2016/07/02/ngrok-tunnel/</url>
<content><![CDATA[<p>不知什么时候，锅内电信把个人pppoe上网的80端口都给封了，更有甚者加入了大内网。于是，苦逼的猿们调微信时候就更崩溃了。。<br>好在网上有不少内网穿透工具，说白了就是从内网主动发送消息，穿透网关，那么必须就得有一台位于公网的Server来转发消息。具体原理可百度。</p>
<p>众多网站提供的转发服务中，有花生棒之类的限流量，也有不限制但是带宽不足的，毕竟这么多人挤在一起想不慢都难。于是乎，本子自己动手丰衣足食的想法，自己搭建一个吧。</p>
<span id="more"></span>
<p>ngrok是这类工具中比较出名的一个了，可惜的是官方已经放弃了开源的1.x版本，2.x版本是官方提供做商业用。关于2.x版本的使用，可以参照这篇文章：<span class="exturl" data-url="aHR0cDovL3d3dy5qaWFuc2h1LmNvbS9wL2EwYTM0Zjc3MDgzNyVFRiVCQyU4OFBTJUVGJUJDJTlBJUU3JUFFJTgwJUU0JUI5JUE2JUU0JUI4JThEJUU5JTk0JTk5JUVGJUJDJThDJUU0JUI4JThEJUU1JTgzJThGJUU1JUJFJTg4JUU1JUE0JTlBJUU3JUJEJTkxJUU3JUFCJTk5JUU1JTg4JUIwJUU1JUE0JTg0JUU3JUIyJTk4JUU4JUI0JUI0JUU2JUEwJUJDJUU1JUJDJThGJUU5JTgzJUJEJUU3JTlDJThCJUU0JUI4JThEJUU4JTg4JTkyJUU2JTlDJThEJUVGJUJDJTg5JUUzJTgwJTgy">http://www.jianshu.com/p/a0a34f770837（PS：简书不错，不像很多网站到处粘贴格式都看不舒服）。<i class="fa fa-external-link-alt"></i></span></p>

<title>Wordpress 在 WebServer 中的权限配置</title>
<url>/2016/08/08/permissions-in-wordpress-on-webserver/</url>
<content><![CDATA[<p>Wordpress默认安装时候的权限设置，会导致安装插件、主题，上传图片时候权限不足。</p>
<p>有些时候朋友询问我这个问题时候，只能笼统的答道把wordpress文件夹权限修改为和php解析器相同的组，实在无办法就也只能临时开777，终究不是长远之道。</p>
<p>于是就有了今天这篇。</p>
<span id="more"></span>
<h4 id="首先，要弄明白，是什么玩意儿的权限不足，导致无法写入"><a href="#首先，要弄明白，是什么玩意儿的权限不足，导致无法写入" class="headerlink" title="首先，要弄明白，是什么玩意儿的权限不足，导致无法写入"></a>首先，要弄明白，是什么玩意儿的权限不足，导致无法写入</h4><p>一般来说，这个得看Server的配置方式，基本上php的话两种常用方式：</p>
<ul>
<li>Apache + 动态链接扩展，windows和*nix一般用的都是这种方式。（注：win系的话，使用此种方式需要使用对应PHP的TS版本，即线程安全版才有插件）</li>
</ul>
<blockquote>
<p>访问使用的是apache运行的用户（组），那么就需要将wordpress文件夹及子目录设置为同httpd.conf中配置。（默认apache）:</p>
</blockquote>
<figure class="highlight bash"><table><tr><td class="code"><pre><span class="line">vi /etc/httpd/conf/httpd.conf</span><br></pre></td></tr></table></figure>
<ul>
<li>Apache or Nginx + PHP-FPM，此种方式效率较高，且配合nginx配置简便，基本原理就是PHP服务监听一个端口，网页服务器将php请求转发至其端口。</li>
</ul>
<blockquote>
<p>需要查看php-fpm的配置文件。（默认apache）:</p>
