nxtreaming / nginx-upstream-conn-cache.patch
Created July 19, 2017 19:54 — forked from aramg/nginx-upstream-conn-cache.patch
# Author: Aram Grigorian <aram@opendns.com>

#
# By default, nginx will close upstream connections after every request.
# The upstream-keepalive module tries to remedy this by keeping a certain minimum number of
# persistent connections open at all times to upstreams. These connections are re-used for
# all requests, regardless of downstream connection source. There are options available
# for load balacing clients to the same upstreams more consistently.
# This is all designed around the reverse proxy case, which is nginxs main purpose.

FFmpeg and libav's playbook: Advanced encoding options with hardware-based acceleration, NVIDIA's NVENC and Intel's VAAPI-based encoder.

Hello guys,

Continuing from this guide to building ffmpeg and libav with NVENC and VAAPI enabled, this snippet will cover advanced options that you can use with ffmpeg and libav on both NVENC and VAAPI hardware-based encoders.

For ffmpeg:

介绍

由于GFW的域名黑名单是不断变化的，如果所有DNS查询都走VPN会丧失CDN加速功能，经常出现本地电信线路，但是却访问网站的联通线路，而且当VPN线路不稳定的时候，会影响所有网站的访问。如果使用域名白名单或黑名单，对于经常访问外国网站的用户，体验很不好，需要用户自己维护域名列表。 该文章介绍如何通过判断并丢弃包含特征IP的DNS包来防止DNS污染，但是又不会失去本地DNS的CDN加速功能，而且还不需要VPN。

前期准备

  • 一台Openwrt路由器
  • 使用dnsmasq作为Openwrt的dns服务器
  • 安装 dig (opkg install bind-dig bind-libs)
  • 安装 iptables 的 string 模块及对应的内核模块 (opkg install iptables-mod-filter kmod-ipt-filter)
