paramiko.ssh_exception.SSHException：讀取 SSH 協議橫幅時出錯 [Errno 104] 對等 inpyhton 重置連接

Question

在列表中給出超過 19 條記錄並通過給定的 sftp 連接詳細信息在循環中傳遞它，但是在運行 19 條記錄后拋出錯誤。 下面是我的代碼。

import paramiko

您可以使用單個 SSH/SFTP 連接：

import time

import paramiko

items = [
    "CBCGG1900089HM",
    "CBCGG1900090HM",
    "CBCGG1900091HM",
    "CBCGG1900092HM",
    "CBCGG1900093HM",
    # ...
    "BCYG1800049",
]

with paramiko.SSHClient() as ssh:
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(
        hostname="amecoll01.logon.ds.ge.com",
        timeout=6000,
        username="WSO",
        password="#AMEuser",
    )
    ftp = ssh.open_sftp()
    for i, item in enumerate(items):
        src = f"/CT_Logs/Optima660_Beijing/{item}/image_analysis.csv"
        dest = f"/home/hvr/sftp_python/Optima660_Beijing {item}/image_analysis.csv"
        try:
            ftp.get(src, dest)
            print("OK", dest)
        except Exception as e:
            print("Failed", item, ":", e)
        if i % 15 == 0:
            print("Sleeping...")
            time.sleep(15)
