ipv6无法连接服务器

[tanyue0504]

版本1.12.2，java8，只安装了forge
连接ipv6服务器提示
io.netty.channel.AbstractChannel$AnnotatedSocketException: Protocol family unavailable:
请问是怎么回事，如何解决？
已经尝试了-Djava.net.preferIPv4Stack＝false和-Djava.net.preferIPv6Address＝true都无效

android 似乎无法使用 ipv6 联机。

你需要使用 termux 创建一个 流量转发

监听 25565 端口 加入游戏时候输入 127.0.0.1 25565

然后将 25565 端口流量 通过流量转发，抵达目标IPV6

也就是说你需要有IPV6和IPV4

import socket
import threading

def handle_client(client_socket, ipv6_host, ipv6_port):
ipv6_socket = None
try:
# 连接到IPv6地址
ipv6_socket = socket.create_connection((ipv6_host, ipv6_port))

    # 开启线程，将IPv4流量转发到IPv6
    threading.Thread(target=forward_traffic, args=(client_socket, ipv6_socket)).start()

    # 从IPv6接收数据并转发回IPv4
    data = ipv6_socket.recv(4096)
    while data:
        client_socket.sendall(data)
        data = ipv6_socket.recv(4096)

except Exception as e:
    print(f"[+] 错误信息: {e}")

finally:
    if ipv6_socket:
        ipv6_socket.close()
    client_socket.close()

def forward_traffic(src_socket, dest_socket):
try:
data = src_socket.recv(4096)
while data:
dest_socket.sendall(data)
data = src_socket.recv(4096)

except Exception as e:
    print(f"[+] 错误信息: {e}")

finally:
    src_socket.close()
    dest_socket.close()

# 设置IPv4监听地址和端口

# 设置IPv6目标地址和端口

ipv6_port = 25565   #这里修改成目标端口

# 启动IPv4到IPv6的代理服务器
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as ipv4_socket:

    ipv4_socket.listen(5)
    print(f"[+] 脚本成功启动，成功在 {ipv4_listen_address}:{ipv4_listen_port} 端口运行")

    while True:
        client, addr = ipv4_socket.accept()
