如何指定在paramiko ssh / sftp连接上使用的其他密码? (类似于scp / ssh中的-c命令行)。
我尝试过以下代码:
self.sshclient = paramiko.SSHClient()
self.sshclient.load_system_host_keys()
self.sshclient.set_missing_host_key_policy(paramiko.AutoAddPolicy())
self.sshclient.connect(hostname, **ssh_kwargs)
self.transport = self.sshclient.get_transport()
self.transport.get_security_options().ciphers = ('arcfour128',)
self.transport.set_keepalive(keepalive)
self.channel = self.transport.open_session()
self.channel.settimeout(timeout)
但是在调试中我可以看到:
2016/02/26 15:27:47 DEBUG Ciphers agreed: local=aes128-ctr, remote=aes128-ctr
2016/02/26 15:27:47 DEBUG using kex diffie-hellman-group1-sha1; server key type ssh-rsa; cipher: local aes128-ctr, remote aes128-ctr; mac: local hmac-sha1, remote hmac-sha1; compression: local none, remote none
我已经读过某个地方,应该在get_security_options()
之后发生连接,反转导致我self.transport
属于NoneType
(似乎传输与连接有关)。
答案 0 :(得分:1)
SSHClient的问题是会话是在connect()
期间根据Transport docs启动的:
更改这些字段的内容和/或顺序会影响基础传输(但前提是在开始会话之前更改它们)。
您可以做的是覆盖Transport
的首选密码:
paramiko.Transport._preferred_ciphers = ('arcfour128', )
self.sshclient = paramiko.SSHClient()
self.sshclient.load_system_host_keys()
self.sshclient.set_missing_host_key_policy(paramiko.AutoAddPolicy())
self.sshclient.connect(hostname, **ssh_kwargs)
...
如果您想要的只是SFTP连接,您可以先创建Transport
并从该传输中创建SFTPClient
对象:
self.transport = paramiko.Transport((hostname, 22))
self.transport.get_security_options().ciphers = ('arcfour128', )
self.transport.connect(username=user, password=pass) # or pkeys, ...
self.transport.set_keepalive(keepalive)
self.sftp = paramiko.SFTPClient.from_transport(self.transport)
self.sftp.put('local_file', 'remote_path')
self.sftp.close()
