除了增加模式转换开头，其他和编译　TP-LINK WR2543N 翻墙固件一样。

下载适合 D-Link DIR505 无线路由器的 Image Builder

Image Builder 又叫 Image Generator，利用它我们可以方便地定制适合自己无线路由器的固件。

选择 OpenWrt 版本：

* 进入　http://downloads.openwrt.org/
* Development Snapshots 最新开发版，我们的选择
* Binary Releases, 最后发行的稳定版本　
* 进入 http://downloads.openwrt.org/snapshots/trunk/

选择 CPU 类型：

* 选择 ar71xx: http://downloads.openwrt.org/snapshots/trunk/ar71xx/

选择 Flash 类型：

* 选择 generic: http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/

下载 Image Builder for DID-505 (Version: 23-Dec-2015 16:38)

* 页面搜索 dir-505 如果找到，说明我们找对了目录
* 下载 Image Builder:

cd ~/Downloads
wget http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64.tar.bz2
tar -xjf  OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64.tar.bz2

确定 OpenWrt 无线路由器的 PROFILE 值

cd OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64
make info

找到自己固件的型号，D-Link DIR 505 A1 的 PROFILE 值是 DIR505A1。如下图：

找出默认应该包含进 OpenWrt 固件的包

对于 D-Link DIR-505 A1 无线路由器来说，可以这样获取：

echo $(wget -qO - http://downloads.openwrt.org/snapshots/trunk/ar71xx/generic/config | sed -ne 's/^CONFIG_PACKAGE_\([a-z0-9-]*\)=y/\1/ip')

2015-12-24 的基础包：

base-files busybox dnsmasq dropbear firewall fstools jsonfilter libc libgcc mtd netifd opkg procd swconfig ubox ubus ubusd uci usign kmod-ledtrig-usbdev kmod-lib-crc-ccitt kmod-nls-base kmod-ip6tables kmod-ipt-conntrack kmod-ipt-core kmod-ipt-nat kmod-nf-conntrack kmod-nf-conntrack6 kmod-nf-ipt kmod-nf-ipt6 kmod-nf-nat kmod-ipv6 kmod-ppp kmod-pppoe kmod-pppox kmod-slhc kmod-gpio-button-hotplug kmod-usb-core kmod-usb-ohci kmod-usb2 kmod-ath kmod-ath9k kmod-ath9k-common kmod-cfg80211 kmod-mac80211 libip4tc libip6tc libxtables libblobmsg-json libexpat libiwinfo libjson-c libnl-tiny libubox libubus libuci ip6tables iptables hostapd-common iw odhcp6c odhcpd ppp ppp-mod-pppoe wpad-mini iwinfo jshn libjson-script uboot-envtools

2014-09-01 查询得到的基础包是：

base-files busybox dnsmasq dropbear firewall fstools jsonfilter libc libgcc mtd netifd opkg procd swconfig ubox ubus ubusd uci kmod-crypto-aes kmod-crypto-arc4 kmod-crypto-core kmod-ledtrig-usbdev kmod-lib-crc-ccitt kmod-nls-base kmod-ip6tables kmod-ipt-conntrack kmod-ipt-core kmod-ipt-nat kmod-ipt-nathelper kmod-ipv6 kmod-ppp kmod-pppoe kmod-pppox kmod-slhc kmod-gpio-button-hotplug kmod-usb-core kmod-usb-ohci kmod-usb2 kmod-ath kmod-ath9k kmod-ath9k-common kmod-cfg80211 kmod-mac80211 libip4tc libip6tc libxtables libblobmsg-json libiwinfo libjson-c libnl-tiny libubox libubus libuci ip6tables iptables hostapd-common iw odhcp6c odhcpd ppp ppp-mod-pppoe wpad-mini iwinfo jshn libjson-script uboot-envtools

默认包要包含在 PACKAGES 命令行参数中，并再加上必要的包：

luci-ssl ipset wget shadowsocks-libev iptables-mod-nat-extra bind-dig

注意，在编译前要把 shadowsocks-libev 及其他要用到的 .ipk 文件放到目录下：

~/Downloads/OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64/packages/base/

如果你的 openWrt 版本是 ATTITUDE ADJUSTMENT，可能加上 iptables-mod-nat-extra 包，如果没安装的话 iptables 的端口转发会不支持。

按照教程 编译 shadowsocks-libev for OpenWrt ipk 安装包

下载和设定自定义翻墙配置文件

下面以 linux 系统 ~/Downloads 下操作为例。

cd ~/Downloads
git clone https://github.com/softwaredownload/openwrt-fanqiang

本地项目文件夹是： ~/Downloads/openwrt-fanqiang

建立一个配置文件夹，以路由器型号结束，如 ~/Downloads/openwrt-dir505。

cd ~/Downloads
mkdir openwrt-dir505

cd openwrt-fanqiang
cp -R openwrt/default/* ~/Downloads/openwrt-dir505/
cp -R openwrt/dir505/* ~/Downloads/openwrt-dir505/

上面的操作，先复制共用的配置文件 openwrt/default/ 到 openwrt-dir505 目录下
然后复制 dir505 专用的配置文件到 openwrt/dir505/ 到 openwrt-dir505 目录下，如果有同名文件就覆盖。

设置可执行权限

cd ~/Downloads/openwrt-dir505
chmod +x usr/bin
chmod +x usr/bin/*
chmod +x etc/uci-defaults
chmod +x etc/uci-defaults/defaults

说明：etc/uci-defaults 目录下的文件会在路由器第一次启动时执行一次。在这里我们设置一些常用值。

必须修改的 DIR505 翻墙配置文件：

• ~/Downloads/openwrt-dir505/etc/shadowsocks.json
  • server 改成你的服务器实际 IP
• ~/Downloads/openwrt-dir505/usr/bin/router
  • wan-username 和 wan-password 改成实际值
• ~/Downloads/openwrt-dir505/usr/bin/shadowsocks-firewall
  • 1.0.9.8 必须改成你的服务器实际 IP

自动复制和修改 DIR-505 翻墙设置文件

config-dir505.sh:

#!/bin/bash

# Author: https://github.com/softwaredownload/openwrt-fanqiang
# Date:   2015-12-24

REPOSITORY=~/Downloads/openwrt-fanqiang
CONFIG=~/Downloads/openwrt-dir505

createdir() {
    rm -rf $CONFIG
    mkdir $CONFIG
}

copy() {
    cp -R $REPOSITORY/openwrt/default/* $CONFIG/
    cp -R $REPOSITORY/openwrt/dir505/* $CONFIG/
}

setmod() {
    chmod +x $CONFIG/usr/bin/shadowsocks-firewall
    chmod +x $CONFIG/etc/uci-defaults
    chmod +x $CONFIG/etc/uci-defaults/*
}

modify() {
    # server ip address
    sed -i 's/1.0.9.8/server_ip/' $CONFIG/etc/shadowsocks.json

    # server_port
    sed -i 's/1098/server_port/' $CONFIG/etc/shadowsocks.json

    # local_port
    sed -i 's/7654/7654/' $CONFIG/etc/shadowsocks.json

    # password
    sed -i 's/killgfw/killgfw/' $CONFIG/etc/shadowsocks.json

    # method
    sed -i 's/aes-256-cfb/aes-256-cfb/' $CONFIG/etc/shadowsocks.json


    # server ip addresss
    sed -i 's/1.0.9.8/server_ip/' $CONFIG/usr/bin/shadowsocks-firewall

    # local_port
    sed -i 's/7654/7654/' $CONFIG/usr/bin/shadowsocks-firewall


    # ppoe username
    sed -i 's/wan-username/wan-username/' $CONFIG/usr/bin/router

    # ppoe password
    sed -i 's/wan-password/wan-password/' $CONFIG/usr/bin/router

    # wifi password
    sed -i 's/icanfly9876/icanfly9876/g' $CONFIG/usr/bin/ap
    sed -i 's/icanfly9876/icanfly9876/g' $CONFIG/usr/bin/router

    # root password
    sed -i 's/\\nfanqiang/\\nfanqiang/' $CONFIG/etc/uci-defaults/defaults
}


if [ "$1" = "createdir" ]; then
    createdir
elif [ "$1" = "copy" ]; then
    copy
elif [ "$1" = "setmod" ]; then
    setmod
elif [ "$1" = "modify" ]; then
    modify
else
    echo "usage: createdir copy setmod modify"
fi

用法：在 config-dir505.sh 所在目录运行：

./config-dir505.sh createdir
./config-dir505.sh copy
./config-dir505.sh setmod
./config-dir505.sh modify    

开始编译 OpenWrt 自动翻墙固件

cd ~/Downloads/OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64
make image PROFILE=DIR505A1 PACKAGES="base-files busybox dnsmasq dropbear firewall fstools jsonfilter libc libgcc mtd netifd opkg procd swconfig ubox ubus ubusd uci usign kmod-ledtrig-usbdev kmod-lib-crc-ccitt kmod-nls-base kmod-ip6tables kmod-ipt-conntrack kmod-ipt-core kmod-ipt-nat kmod-nf-conntrack kmod-nf-conntrack6 kmod-nf-ipt kmod-nf-ipt6 kmod-nf-nat kmod-ipv6 kmod-ppp kmod-pppoe kmod-pppox kmod-slhc kmod-gpio-button-hotplug kmod-usb-core kmod-usb-ohci kmod-usb2 kmod-ath kmod-ath9k kmod-ath9k-common kmod-cfg80211 kmod-mac80211 libip4tc libip6tc libxtables libblobmsg-json libexpat libiwinfo libjson-c libnl-tiny libubox libubus libuci ip6tables iptables hostapd-common iw odhcp6c odhcpd ppp ppp-mod-pppoe wpad-mini iwinfo jshn libjson-script uboot-envtools luci-ssl ipset wget shadowsocks-libev iptables-mod-nat-extra bind-dig" FILES=~/Downloads/openwrt-dir505

报告错误：

opkg_install_cmd: Cannot install package kmod-ipv6

移除 kmod-ipv6 再次编译，成功。

查看编译好的固件:

cd ~/Downloads/OpenWrt-ImageBuilder-ar71xx-generic.Linux-x86_64/bin/ar71xx/
ls -lh *505*.bin
... 7.6M Dec 24 15:20 openwrt-ar71xx-generic-dir-505-a1-squashfs-factory.bin
... 5.4M Dec 24 15:20 openwrt-ar71xx-generic-dir-505-a1-squashfs-sysupgrade.bin

升级固件要用到的是　openwrt-ar71xx-generic-dir-505-a1-squashfs-sysupgrade.bin，如果在原厂固件上刷要用 openwrt-ar71xx-generic-dir-505-a1-squashfs-factory.bin

先本地修改好配置文件再编译，然后把翻墙固件刷进 D-Link DIR-505 A1 后，就能零设置智能、自动翻墙。

只要配置文件设置不出差错，编译固件一般都能成功，保存好这个固件，以后随便折腾路由器，出现问题大不了重刷一次，几分钟时间就一切都恢复正常。
