paramiko错误ai_socktype不支持Servname

我无法通过paramiko连接到其他服务器:

import paramiko
import sys
import os

hostname = 'server1'
port = 22
username = 'root'
password = 'password'`enter code here`
def deploy_key(key, hostname, username, password):
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.connect(hostname, username, password)
    client.exec_command('mkdir -p ~/.ssh/')
    client.exec_command('echo "%s" > ~/.ssh/authorized_keys' % key)
    client.exec_command('chmod 644 ~/.ssh/authorized_keys')
    client.exec_command('chmod 700 ~/.ssh/')

key = open(os.path.expanduser('~/.ssh/id_rsa.pub')).read()
deploy_key(key, hostname, username, password)

这是输出:

socket.AF_UNSPEC, socket.SOCK_STREAM):
socket.gaierror: [Errno -8] Servname not supported for ai_socktype

问题在于client.connect()调用,它期望port是第二个参数并且是一个整数,而你将username(string)作为第二个参数.尝试用下面的行替换它.client.connect(主机名,用户名=用户名,密码=密码),应该有效.
