解決geth連接不到節點，無法同步的問題

問題的起源

直接啓動geth，完全無法同步，找了很久都沒有連接到可用的節點，於是開始網上查找資料，看到了一堆堆的static-nodes.json文件，我拿來試了下，還是找不到，傳說中的火星節點，也沒再維護了，總不能讓我一個一個的試這些文件吧。。。。

解決方式

我想了個辦法就是把所有網絡上搜集來的節點綜合起來，然後用代碼一個一個的嘗試，把能連接的全找到，然後提取出新的static-node.js。

上代碼

首先是收集來的所有節點組成一個列表

list.py（由於博客文字限制，沒把發把列表都貼上來，需要看的到文章最後找github地址查看哈）

node_list = ["enode://979e4154866787fe2aceba07ae24118380ae1b7d89d66b232a20cc674d230753a94c461e3418952b02abd443087c6879444acb4340d339ece193d420aff16469@47.96.56.167:61776",
。。。。。。。。。。。。。。。。。
]

接着一步一步的嘗試
main.py

import list
from socket import *
socket_list = []
find_list = []
for list_item in list.node_list:
    item = list_item.split("@")[1].split(":")
    ip = item[0]
    port = item[1]
    s=socket(AF_INET,SOCK_STREAM)
    s.settimeout(1)
    try:
        x = s.connect((ip,int(port)))
    except:
        pass
    else:
        find_list.append(list_item)
print("[")
for i in range(len(find_list)):
    print('"'+find_list[i]+'"'+(',' if  i<len(find_list)-1 else ''))
print("]")

然後運行

python3 main.py

得出最終結果
