Python paramiko中exec_命令和invoke_shell方法的EOF错误

我试图使用python paramiko在windows机器上的linux服务器上执行一个命令，我使用了这两种方法

1.exec_命令

2.2.1壳

它们都给出了EOF错误

import paramiko
import time
def ConnectSSH1(host, port, username, password):
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(host, int(port), username, password)
    chan = ssh.invoke_shell() # Throws EOF error here 
    #stdin, stdout, stderr = ssh.exec_command("ls")   #Throws EOF error here with exec_command
    chan.send("ls -a")
    time.sleep(5)
    output = chan.recv(9999)
    print (output)
    print (command)
    return (output)

exec_命令出错
