通过SFTP连接到PyCharm中的部署服务器不起作用

Question

我已在中配置了带有登录名和密码的SFTP连接 PyCharm 2019.3.3 (Build #PY-193.6494.30)在{}上。当我尝试“测试SFTP连接”时，我没有得到任何错误，但得到了一个“通过SFTP连接”的循环，该循环从未超时。每次我重新安装PyCharm时，它都会工作2-3次，但在那之后，连接就不再建立，我得到了如上所述的连接循环。当我重新安装PyCharm时，我确保从~/Library中删除所有相关文件。正在通过VPN隧道建立连接。我可以完美地ssh到相同的部署地址，只有PyCharm无法连接

我可以从日志中获得以下信息：

我通常通过我的私有ssh密钥登录，但使用用户+密码登录也可以：

$ ssh -o PreferredAuthentications=password -o PubkeyAuthentication=no 10.5.166.81
The authenticity of host '10.5.166.81 (10.5.166.81)' can't be established.
ECDSA key fingerprint is SHA256:ELdUhvqI6us+QR/CJRwb0u4a+zUcvWLUdZdWeYmhj2s.
Are you sure you want to continue connecting (yes/no)? yes
user@10.5.166.81's password:
Welcome to Ubuntu 18.04.2 LTS (GNU/Linux 4.15.0-46-generic x86_64)

我注意到，对于新部署服务器，PyCharm有时不要求我接受ECDSA密钥指纹。也许这会导致PyCharm无休止地尝试“通过SFTP连接”，同时等待用户接受从未出现的密钥指纹提示

我不使用KeX算法，因此建议的解决方案here无法使用

Answer 1

我能够解决这个问题。日志表明sftp有问题。通过调试sftp -v user@10.5.166.81的输出，我可以看到通过SSH进行的身份验证工作正常，但sftp将在这之后停止。事实证明，我在~/.bashrc中使用了zsh命令，该命令对ssh会话很有效，但对sftp会话无效。从bashrc中删除这一行并使用chsh <user> -s /bin/zsh解决了问题，现在成功地启用了Connecting by SFTP
