Question

我想用python模块paramsiko连接到我的远程机器。首先，我尝试使用密码，没关系，就像这样：

import paramiko
import socket
import os

paramiko.util.log_to_file('demo_sftp.log')
username = 'xxxxx'
hostname = 'dev81'
Port = 22
password = "xxxxx"
t = paramiko.Transport((hostname, Port))
t.connect(None, username, password)
sftp = paramiko.SFTPClient.from_transport(t)
# dirlist on remote host
dirlist = sftp.listdir('.')
print("Dirlist: %s" % dirlist)

然后我想删除密码，使用密钥，根据demo_sftp中的演示，如下所示：

import paramiko
import socket
import os

paramiko.util.log_to_file('demo_sftp.log')
username = 'xxxxx'
hostname = 'dev81'
Port = 22
password = None
host_keys = paramiko.util.load_host_keys(os.path.expanduser('~/.ssh/known_hosts'))
hostkeytype = host_keys[hostname].keys()[0]
hostkey = host_keys[hostname][hostkeytype]
print('Using host key of type %s' % hostkeytype)
t = paramiko.Transport((hostname, Port))
t.connect(hostkey, username, password, gss_host=socket.getfqdn(hostname),
            gss_auth=True, gss_kex=True)
sftp = paramiko.SFTPClient.from_transport(t)
# dirlist on remote host
dirlist = sftp.listdir('.')
print("Dirlist: %s" % dirlist)

此失败例外 paramiko.ssh_exception.BadAuthenticationType: ('Bad authentication type', [u'publickey', u'password']) (allowed_types=[u'publickey', u'password'])

我可以使用命令ssh xxxxx@dev81无需密码登录

如果您具有密码短语作为密钥对

它抛出此错误

paramiko.ssh_exception.BadAuthenticationType: ('Bad authentication type', [u'publickey', u'password']) (allowed_types=[u'publickey', u'password'])

要解决此问题

ssh.connect('<your ip>', port=22, username='<username>',password='<passphrase for the RSA key>', key_filename='<full path of the private key>')

python ssh（paramiko）无法连接到没有密码的远程计算机？
