python代码连接到sftp服务器

Question

我发现这个代码连接到远程sftp服务器的用户名，密码和主机的帮助下，但我也需要包括端口号，任何一个可以让他们知道如何包括端口在这段代码中的数字，也是这段代码 'parmiko.util.log_to_file（log_filename）'我应该怎样为log_filename进行硬编码？ Iam在unix环境中运行此代码。

import os 
import paramiko 
server, username, password = ('host', 'username', 'password') 
ssh = paramiko.SSHClient() 
parmiko.util.log_to_file(log_filename)  
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy()) 

' #In case the server's key is unknown,' 
#we will be adding it automatically to the list of known hosts 
ssh.load_host_keys(os.path.expanduser(os.path.join("~", ".ssh", "known_hosts"))) 

#Loads the user's local known host file 
ssh.connect(server, username=username, password=password) 
ssh_stdin, ssh_stdout, ssh_stderr = ssh.exec_command('ls /tmp') 

print "output", ssh_stdout.read() #Reading output of the executed co'mmand 
error = ssh_stderr.read() 

#Reading the error stream of the executed command 
print "err", error, len(error) 

#Transfering files to and from the remote machine' 
sftp = ssh.open_sftp() 
'sftp.get(remote_path, local_path)' 
sftp.put(local_path, remote_path) 
sftp.close() 
ssh.close()

有一个port=命名参数ssh.connect（）方法。见manual

例子：

ssh.connect(server, port=portnumber, username=username, password=password)
