ipv6，ddns，阿里云，下级设备配置

tkeweng

我这里的网络自带ipv6-pd，组了台nas想外网直接域名访问。自己折腾了好久，看了一堆帖子，最后把两个代码结合了下，总算搞定了。脚本代码如下。

1. #!/bin/sh
   
2. #前置函数
   
3. urlencode1() {
   
4. local length="${#1}"
   
5. i=0
   
6. out=""
   
7. for i in $(awk "BEGIN { for ( i=0; i<$length; i++ ) { print i; } }")
   
8. do
   
9. local c="${1:$i:1}"
   
10. case $c in
    
11. [a-zA-Z0-9.~'&'=_-]) out="$out$c" ;;
    
12. *) out="$out`printf '%%%02X' "'$c"`" ;;
    
13. esac
    
14. i=$(($i + 1))
    
15. done
    
16. echo -n $out
    
17. }
    
18. urlencode2() {
    
19. local length="${#1}"
    
20. i=0
    
21. out=""
    
22. for i in $(awk "BEGIN { for ( i=0; i<$length; i++ ) { print i; } }")
    
23. do
    
24. local c="${1:$i:1}"
    
25. case $c in
    
26. [a-zA-Z0-9.~_-]) out="$out$c" ;;
    
27. *) out="$out`printf '%%%02X' "'$c"`" ;;
    
28. esac
    
29. i=$(($i + 1))
    
30. done
    
31. echo -n $out
    
32. }
    
33. send_request() {
    
34. args="AccessKeyId=$ak&Action=$1&Format=json&$2&Version=2015-01-09"
    
35. StringToSign1="$(urlencode1 $args)"
    
36. StringToSign2="GET&%2F&$(urlencode2 $StringToSign1)"

39. echo $RESULT
    
40. }
    
41. query_recordid() {
    
42. if [ "$host" = "@" ]; then
    
43. echo `send_request "DescribeSubDomainRecords" "SignatureMethod=HMAC-SHA1&SignatureNonce=$timestamp&SignatureVersion=1.0&SubDomain=$domain&Timestamp=$timestamp"`
    
44. else

46. fi
    
47. }
    
48. update_record() {
    
49. echo `send_request "UpdateDomainRecord" "RR=$host&RecordId=$1&SignatureMethod=HMAC-SHA1&SignatureNonce=$timestamp&SignatureVersion=1.0&Timestamp=$timestamp&Type=AAAA&Value=$ip"`

配置信息里几个改一下就行，之后怎么定时运行就是另一件事了。可以直接计划任务，也可以放到pppoe拨号时运行的那个文件夹里，拨号时运行。
也可以配合固件整合的ddns，直接修改IP来源为脚本，脚本里就写一句

1. cat /tmp/hosts/odhcpd |grep $DUID|cut -f9 -d' '|cut -f1 -d'/'

复制代码

$DUID修改下。完事。

我也在搞这个。。刚刚解决ipv6访问外网。nas在内网用frp太慢了。你这个应该可以解决我的这个问题。
