群晖使用阿里云DDNS(ipv4和ipv6)

复制,写成sh脚本,添加进群晖定时任务即可。

ipv4

注意前四个需要自己填入,还有获取ip那里要注意网络接口,我的是ppp0。

#!/bin/sh ApiId="***************" ApiKey="***************" Domain='************' SubDomain='********' #这四个自己写 Nonce=$(date -u "+%N") Timestamp=$(date -u "+%Y-%m-%dT%H%%3A%M%%3A%SZ") Nonce=$Timestamp urlencode() { local raw="$1"; local len="${#raw}" local encoded="" for i in `seq 1 $len`; do local j=$((i+1)) local c=$(echo $raw | cut -c$i-$i) case $c in [a-zA-Z0-9.~_-]) ;; *) c=$(printf '%%%02X' "'$c") ;; esac encoded="$encoded$c" done echo $encoded } # $1 = query string getSignature() { local encodedQuery=$(urlencode $1) local message="GET&%2F&$encodedQuery" local sig=$(echo -n "$message" | openssl dgst -sha1 -hmac "$ApiKey&" -binary | openssl base64) echo $(urlencode $sig) } sendRequest() { local sig=$(getSignature $1) local result=$(wget -qO- --no-check-certificate --content-on-error "https://alidns.aliyuncs.com?$1&Signature=$sig") echo $result } getRecordId() { echo "获取 $SubDomain.$Domain 的 IP..." >&2 local queryString="AccessKeyId=$ApiId&Action=DescribeSubDomainRecords&Format=JSON&SignatureMethod=HMAC-SHA1&SignatureNonce=$Nonce&SignatureVersion=1.0&SubDomain=$SubDomain.$Domain&Timestamp=$Timestamp&Type=A&Version=2015-01-09" local result=$(sendRequest "$queryString") local code=$(echo $result | sed 's/.*,"Code":"\([A-z]*\)",.*/\1/') local recordId=$(echo $result | sed 's/.*,"RecordId":"\([0-9]*\)",.*/\1/') if [ "$code" = "$result" ] && [ ! "$recordId" = "$result" ]; then local ip=$(echo $result | sed 's/.*,"Value":"\([0-9\.]*\)",.*/\1/') if [ "$ip" == "$NewIP" ]; then echo "IP 无变化, 退出脚本..." >&2 echo "quit" else echo $recordId fi else echo "null" fi } # $1 = record ID, $2 = new IP updateRecord() { local queryString="AccessKeyId=$ApiId&Action=UpdateDomainRecord&DomainName=$Domain&Format=JSON&RR=$SubDomain&RecordId=$1&SignatureMethod=HMAC-SHA1&SignatureNonce=$Nonce&SignatureVersion=1.0&Timestamp=$Timestamp&Type=A&Value=$2&Version=2015-01-09" local result=$(sendRequest $queryString) local code=$(echo $result | sed 's/.*,"Code":"\([A-z]*\)",.*/\1/') if [ "$code" = "$result" ]; then echo "$SubDomain.$Domain 已指向 $NewIP." >&2 else echo "更新失败." >&2 echo $result >&2 fi } # $1 = new IP addRecord() { local queryString="AccessKeyId=$ApiId&Action=AddDomainRecord&DomainName=$Domain&Format=JSON&RR=$SubDomain&SignatureMethod=HMAC-SHA1&SignatureNonce=$Nonce&SignatureVersion=1.0&Timestamp=$Timestamp&Type=A&Value=$1&Version=2015-01-09" local result=$(sendRequest $queryString) local code=$(echo $result | sed 's/.*,"Code":"\([A-z]*\)",.*/\1/') if [ "$code" = "$result" ]; then echo "$SubDomain.$Domain 已指向 $NewIP." >&2 else echo "添加失败." >&2 echo $result >&2 fi } # Get new IP address echo "获取当前 IP..." NewIP=`ip addr show ppp0 | grep "inet" | awk '{print $2}' | awk -F"/" '{print $1}' ` echo "当前 IP 为 $NewIP." # Get record ID of sub domain recordId=$(getRecordId) if [ ! "$recordId" = "quit" ]; then if [ "$recordId" = "null" ]; then echo "域名记录不存在, 添加 $SubDomain.$Domain 至 $NewIP..." addRecord $NewIP else echo "域名记录已存在, 更新 $SubDomain.$Domain 至 $NewIP..." updateRecord $recordId $NewIP fi fi 

ipv6

同样前四个自己填,和上边的类似。网络接口也同理,可以进群晖ssh,用ip addr自己查接口名称。
