我正在尝试paramiko和AWS,并且我无法使SSH工作。它在我手动SSH进入服务器并且没有收到任何错误消息时起作用。我可以帮忙弄清楚我做错了什么吗?从python paramiko获得标准输出的问题
我试过stdout.read()和stdout.readlines()。两人都空虚。
代码:
#Load the key into a file and attempt to SSH in
key = paramiko.RSAKey.from_private_key_file('TestInstanceKey.pem')
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
print("Connecting")
#Try to ssh in and run and display ifconfig
try:
ssh.connect(hostname=instance.public_ip_address, username="ec2-user",
pkey=key)
print("Connected")
print("Executing ifconfig")
stdin, stdout, stderr = ssh.exec_command("ifconfig")
lines = stdout.read()
print(lines)
for line in lines:
print(line)
ssh.close()
except Exception as e:
print(e)
input("Press enter to continue...")
输出:
Connecting
Connected
Executing ifconfig
b''
输出,当我SSH到服务器:
ssh -i TestInstanceKey.pem [email protected]

有什么来自stderr? – Kyle
b'bash:ifconfig:找不到命令\ n' 看起来它需要完整路径。再试一次。 – Smipims
