我正在尝试所有可能的方法来连接到 SFTP 服务器 --
对于此代码
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
mykey = paramiko.RSAKey.from_private_key_file("/Users/roth/.ssh/id_rsa", password="XXXX")
我明白
paramiko.ssh_exception.SSHException: Could not deserialize key data.
如果我执行以下操作
client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname="128.xx.xx.xx", username="roth", passphrase="roth", password="XXXX", key_filename="/Users/roth/.ssh/id_rsa")
我明白
paramiko.ssh_exception.NoValidConnectionsError: [Errno None] Unable to connect to port 22 on 128.xx.xx.xx
我不知道为什么，因为我可以通过使用 key + 密码或仅密码使用终端连接到 SFTP:
ssh -vvv

最佳答案
Executing proxy command: exec ssh -W 128.xx.xx.xx:22 jump.xxx.xxx.edu
您的 ssh 使用跳转代理服务器(又名 SSH 隧道)进行连接。
要在 JSch 中实现跳转服务器，请参阅 official JumpHosts.java example .
顺便说一句，在最新版本的 OpenSSH 中，有比使用“代理命令”更好的通过跳转服务器进行连接的方法。请参阅How can I download a file from a host I can only SSH to through another host?
关于python - "ssh"Paramiko 中的等效代理命令，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/59503547/
