openwrt使用dnspod api自动更新ddns

发布时间:February 12, 2019 // 分类:OpenWrt // No Comments

通过dnspod api实现动态ddns更新ip,ipv4和ipv6支持,shell脚本如下:

#!/bin/bash
token="www.haiyun.me"
domain="haiyun.me"
if which jq > /dev/null; then
  json="jq"
elif which jsonfilter > /dev/null; then
  json="jsonfilter"
else
  echo 'please install jq or jsonfilter'
  exit
fi
if ! which curl > /dev/null || ! which curl > /dev/null; then
  echo 'please install curl and grep'
  exit
fi
if [[ $1 == "list" ]]; then
  curl -s -d "login_token=$token&format=json&domain=$domain" "https://dnsapi.cn/Record.List" | jq -r -M '.records[]|.name + "\t\t " + .type + "\t\t " + .value'
  exit
fi
if [[ $1 == "delete" ]]; then
  if [[ ! $3 || ! $2 ]]; then
    echo 'use ddns.sh delete name type'
    exit
  fi
  id=$(curl -s -d "login_token=$token&format=json&domain=$domain" "https://dnsapi.cn/Record.List" | jq -r -e ".records | .[] | select(.name == \"$2\" and .type == \"${3^^}\")|.id")
  if [[ $id ]]; then
    if curl -s -d "login_token=$token&format=json&domain=$domain&record_id=$id" https://dnsapi.cn/Record.Remove | grep -q '"code":"1"'; then
      echo "sus"
    fi
  else
    echo 'no record'
  fi
  exit
fi
if [[ ! $1 || ! $2 ]]; then
  echo 'use ddns.sh name ip'
  echo 'use ddns.sh list'
  echo 'use ddns.sh delete name type'
  exit
fi
name=$1
new_ip=$2
if [[ $new_ip =~ ^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$ ]]; then
  #sleep 10
  #curl http://192.168.168.6/announce.php --silent --output /dev/null
  record_type='A'
  echo 'ipv4'
elif [[ $new_ip =~ ^([0-9a-fA-F]{0,4}:){1,7}[0-9a-fA-F]{0,4}$ ]]; then
  echo 'ipv6'
  record_type='AAAA'
else
  echo "invalid IP address $new_ip"
  #logger -t ddns "invalid IP address $new_ip"
  exit
fi
curl -s -d "login_token=$token&format=json&domain=$domain" "https://dnsapi.cn/Record.List" -o /tmp/dns.txt
if ! grep -q '"code":"1"' /tmp/dns.txt; then
  echo 'get record list error'
  exit
fi

if [[ $record_type == "AAAA" ]]; then
  if [[ $json == "jq" ]]; then
    id=$(jq -r -e ".records | .[] | select(.name == \"$name\" and .type == \"AAAA\")|.id" /tmp/dns.txt)
    ip=$(jq -r -e ".records | .[] | select(.name == \"$name\" and .type == \"AAAA\")|.value" /tmp/dns.txt)
  else
    ip=$(jsonfilter -i /tmp/dns.txt -e "@.records[@.name='$name'&&@.type='AAAA'].value")
    id=$(jsonfilter -i /tmp/dns.txt -e "@.records[@.name='$name'&&@.type='AAAA'].id")
  fi
elif [[ $record_type == "A" ]]; then
  if [[ $json == "jq" ]]; then
    id=$(jq -r -e ".records | .[] | select(.name == \"$name\" and .type == \"A\")|.id" /tmp/dns.txt)
    ip=$(jq -r -e ".records | .[] | select(.name == \"$name\" and .type == \"A\")|.value" /tmp/dns.txt)
  else
    ip=$(jsonfilter -i /tmp/dns.txt -e "@.records[@.name='$name'&&@.type='A'].value")
    id=$(jsonfilter -i /tmp/dns.txt -e "@.records[@.name='$name'&&@.type='A'].id")
  fi
fi
#echo $name;
#echo $id;
#echo $ip;
#echo $new_ip;
if [[ $ip == $new_ip ]]; then
  echo 'no update needed'
  exit
fi
if [[ $id ]]; then
  echo "mod ip"
  if curl -s -d "login_token=$token&format=json&domain=$domain&record_id=$id&value=$new_ip&record_type=$record_type&record_line_id=0&sub_domain=$name" https://dnsapi.cn/Record.Modify | grep -q '"code":"1"'; then
    echo "sus"
  fi
else
  echo "add ip"
  if curl -s -d "login_token=$token&format=json&domain=$domain&sub_domain=$name&record_type=$record_type&record_line_id=0&value=$new_ip" https://dnsapi.cn/Record.Create | grep -q '"code":"1"'; then
    echo "sus"
  fi
fi

在/lib/netifd/ppp-up文件内调用上面的脚本,当pppoe网络连接成功时会执行此文件,$4变量为pppoe连接的本地IP。

/usr/bin/update-ip.sh name $4 > /dev/null 2>&1 &

pppoe只能传递公网ipv4,使用ifstatus可获取pppoe接口ipv6地址和分配内网的ipv6前缀,根据mac生成的ipv6后缀可为内网其它机器做ddns。

ifstatus wan_6
ifstatus wan
ubus call network.interface dump
jsonfilter -i /tmp/wan6.txt -e '@["ipv6-prefix"][0].address'
jsonfilter -i /tmp/wan6.txt -e '@["ipv6-address"][0].address'

ROS动态DNS更新IP到dyndns.org

发布时间:November 2, 2012 // 分类:ROS // No Comments

本脚本用于ROS更新IP至DDNS,适用于dyndns.org。

#http://www.haiyun.me
#设置变量
:local ddnsuser "onovps"
:local ddnspass "onovps"
:local ddnshost "onovps.dyndns.org"
:local ddnsinterface "pppoe-out1"

#设置IP变量
:global newip
:global lastip
:if ([ :typeof $lastip ] = nil ) do={ $lastip "0" }

#获取当前外网IP
:set newip [ /ip address get [/ip address find interface=$ddnsinterface ] address ]
#去掉IP的网段
:set newip [:pick $newip 0 [:find $newip "/"]]

#判断新旧IP是否相同
:if ([ :typeof $newip ] = nil ) do={
   :log info ("DynDNS: " . $ddnsinterface . "没有获取到外网IP")
} else={
  :if ($newip != $lastip) do={
    :log info ("DynDNS:" . $ddnsinterface . "更新IP为" . $newip)
    :local str "/nic/update?hostname=$ddnshost&myip=$newip&wildcard=NOCHG&mx=NOCHG&backmx=NOCHG"
    /tool fetch address=members.dyndns.org src-path=$str mode=http user=$ddnsuser password=$ddnspass dst-path=("/DynDNS.".$ddnshost)
    :delay 1
    :local str [/file find name="DynDNS.$ddnshost"];
    /file remove $str
#设置新IP为上次IP,供下次调用
    :global lastip $newip
  }
}

使用BIND配置动态DDNS

发布时间:July 6, 2012 // 分类:DNS // No Comments

BIND下可通过nsupdate远程、本地动态更新域指向,无需重启BIND,即DDNS,相应域规则需配置allow-update权限。
直接允许指定IP更新:

#http://www.haiyun.me
allow-update { 8.8.8.8; };

或以密钥方式验证:

dnssec-keygen -a HMAC-MD5 -b 512 -n HOST ddns #生成密钥类型为HOST,主机名ddns
cat Kddns.+157+61025.key #查看生成的密钥,后续需添加到配置文件中
ddns. IN KEY 512 3 157 S/ZqoSgQB3OZ8M0Bm4rTFJp54zTEZoBqHLMjg/ljdCTH/8VTYMvxornk y0bCpuAC0VwHzX3Eq+2Fymw/L+iQdA==

添加到主配置:

key "ddns" {
        algorithm hmac-md5;
        secret "S/ZqoSgQB3OZ8M0Bm4rTFJp54zTEZoBqHLMjg/ljdCTH/8VTYMvxornk y0bCpuAC0VwHzX3Eq+2Fymw/L+iQdA==";
};
zone "www.haiyun.me" IN { #相应域授权
        type master;
        file "named.www.haiyun.me";
        allow-query { any; };
        update-policy {
        grant ddns name ddns.www.haiyun.me. A; #仅允许对ddns.www.haiyun.me A记录进行更改
        };

复制生成的公钥与私钥到执行更新的服务器,执行更新操作:

nsupdate -k Kddns.+157+61025.key
> server 184.164.141.188
> update delete ddns.www.haiyun.me
> update add ddns.www.haiyun.me 60 A 8.8.8.8
> send
> quit

新建脚本自动更新IP:

#!/bin/bash
while ture
do
interface=pppoe-wan
dnsserver=184.164.141.188
keyfile=/root/Kddns.+157+61025.key
keydir=/root/
domain=ddns.www.haiyun.me
ddnsip=ping -c 1 $domain|grep from|awk '{print $4}'|sed 's/:$//g'
ip=`ifconfig pppoe-wan|grep inet|awk -F"[ ]+|[:]" ' {print $4}'`
if [ $ddnsip == $ip ]
    echo "当前IP没有更改"
else
cd $keydir
echo "server $dnsserver"                       >  ddns
echo "update delete $domain A "               >>  ddns
echo "update add    $domain 600 A $ip"        >>  ddns
echo "send"                                   >>  ddns
nsupdate -k $keyfile -v ddns
fi
sleep 300
done
