Windows Server 2016 上的 SFTP，错误：从子进程获取 eof

问题描述 投票：0回答：2

尝试使用 FileZilla 连接到 Windows Server 2016 上的 SFTP 时，我收到“从子进程获取 eof”。调试跟踪如下。有谁知道为什么？还有补救办法吗？

备注：

    OpenSSH 正在服务器上运行
    2. 我可以使用 PuTTY 使用用户名和密码打开 SSH 会话
    3. 我可以使用 PuTTY 导航到文件夹（cd、dir 等）
    4. TLS1.x 由于其他安全原因被禁用，因此我无法使用“通过 TLS 的显式 FTP”
    5. 下面日志中的“xxx.xxx.xxx.xxx”是我出于安全原因编辑的IP
FileZilla 调试日志：

连接到 Linux 机器时我遇到了“同样”的问题。

错误消息

    跟踪：
  • 从子进程中获取 eof
    • 跟踪：
  • CControlSocket::ResetOperation(66)
    • 跟踪：
  • CSftpConnectOpData::Reset(66)，处于状态 3
具有零调试输出的 Filezilla 说：

Status: Connecting to server.net... Response: fzSftp started, protocol_version=11 ... Status: Connected to server.net Error: Fatal: unable to initialise SFTP on server: could not connect Error: Could not connect to server 
在菜单中打开调试模式
FileZilla > Edit > Settings > Debug > Debug information in message log: 3-verbose


Status: Connecting to server.net...
Response:   fzSftp started, protocol_version=11
...
Status: Connected to server.net
Error:  Fatal: unable to initialise SFTP on server: could not connect
Error:  Could not connect to serverError:   Fatal: unable to initialise SFTP on server: could not connect
Trace:  Got eof from child process
Trace:  CControlSocket::ResetOperation(66)
Trace:  CSftpConnectOpData::Reset(66) in state 3
Error:  Could not connect to server

根本原因
从服务器发送的
欢迎消息对于SFTP协议而言太长！
解决方案

就我而言，我最近创建了该消息，因此解决方案非常简单：使用 ssh
 登录到远程服务器，并清除我的 
~/.bashrc
 文件生成的不必要的输出，我最近在其中设置了自定义欢迎消息，以在打开新 shell 后显示。

修复：




导航至：C:\ProgramData\
    

  1. 在记事本中打开“sshd_config”
    2. 

  2. 找到“子系统”设置
    3. 

  3. 将完整路径设置为特定于：“C:\Program Files\OpenSSH-Win64\sftp-server.exe”
    4. 

  4. 保存文件
    5. 

  5. 运行服务.msc
    6. 

  6. 找到“OpenSSH SSH服务器”
    7. 

  7. 右键单击并重新启动
    8. 

  8. 

# 覆盖无子系统的默认值
子系统 sftp "C:\Program Files\OpenSSH-Win64\sftp-server.exe"
