我的PY源码如下：
import paramiko
client = paramiko.SSHClient()
hostname=‘192.168.1.1‘
port = '22'
username='admin'
password='123456'
if __name__=="__main__":
client.connect(client,hostname,port,username,password)
stdin,stdout,stderr=s.exec_command('show router ospf neighbor')
ss=stdout.read()
print ss
client.close()
出错信息：
Traceback (most recent call last):
File "D:\桌面\sshconn.py", line 8, in <module>
client.connect(client,hostname,port,username,password)
File "c:\python25\Lib\site-packages\paramiko\client.py", line 278, in connect
for (family, socktype, proto, canonname, sockaddr) in socket.getaddrinfo(hostname, port, socket.AF_UNSPEC, socket.SOCK_STREAM):
TypeError: getaddrinfo() argument 1 must be string or None
我试过了几次都是不成功登陆。
我所使用paramiko 的版本是1.7.6
说明手册如下：
connect(self, hostname, port=22, username=None, password=None, pkey=None, key_filename=None, timeout=None, allow_agent=True, look_for_keys=True) source code
Connect to an SSH server and authenticate to it. The server's host key is checked against the system host keys (see load_system_host_keys) and any local host keys (load_host_keys). If the server's hostname is not found in either set of host keys, the missing host key policy is used (see set_missing_host_key_policy). The default policy is to reject the key and raise an SSHException.
Authentication is attempted in the following order of priority:
•The pkey or key_filename passed in (if any)
•Any key we can find through an SSH agent
•Any "id_rsa" or "id_dsa" key discoverable in ~/.ssh/
• lain username/password auth, if a password was given
If a private key requires a password to unlock it, and a password is passed in, that password will be used to attempt to unlock the key.
Parameters:
•hostname (str) - the server to connect to
•port (int) - the server port to connect to
•username (str) - the username to authenticate as (defaults to the current local username)
•password (str) - a password to use for authentication or for unlocking a private key
•pkey (PKey) - an optional private key to use for authentication
•key_filename (str or list(str)) - the filename, or list of filenames, of optional private key(s) to try for authentication
•timeout (float) - an optional timeout (in seconds) for the TCP connect
•allow_agent (bool) - set to False to disable connecting to the SSH agent
•look_for_keys (bool) - set to False to disable searching for discoverable private key files in ~/.ssh/
Raises:
•BadHostKeyException - if the server's host key could not be verified
•AuthenticationException - if authentication failed
•SSHException - if there was any other error connecting or establishing an SSH session
•socket.error - if a socket error occurred while connecting |
