duckdns 不能更新 ipv6

ifreeswan

pve 上 haos ，用 addon duckdns 不能更新 ipv6，没有什么办法。最后，把 duckdns 安装到 pve 上，比 addon 方便，。
删除了 hoas 上的 duckdns ，保留 Nginx Proxy Manager 。

用 ai 写的脚本 在 pve 中 获取 haos 的 ipv6 ，更新 duckdns

#!/bin/bash

set -e

LOG_FILE="/var/log/ipv6_change.log"
INTERFACE="vmbr0"
DOMAIN="homeassistant.local"


get_if_ipv6_address() {
    local interface="$1"
    echo $(ip -6 addr show dev $interface scope global -deprecated | awk '

            address = $2;
            getline;
            match($0, /valid_lft ([0-9]+)sec/, arr);
            valid_lft = arr[1];
            print valid_lft " " address;
        }
    ' | sort -s -n -k 1,1 | tail -n 1 | awk '{print $2}'
    )
}


get_domain_ipv6_address() {
    local domain="$1"
#    dig "$domain" AAAA +short | awk '/^$IF_IPV6_PREFIX/ {print $1}'
    while IFS= read -r ipv6; do

        if [ "$IF_IPV6_PREFIX" = "$ipv6_prefix" ] ; then echo $ipv6 ; fi
    done < <(dig "$domain" AAAA +short | grep -v '^fe80::')

log_change() {
