Question

我有四个带有raspbian的树莓味。现在我需要在每个主机上执行相同的shell命令。我无法使用cron自动执行作业，因为每次我需要它时它们都是不同的。所以我想我可以写一个python脚本为我做这个：

hosts = ["host1", "host2", "host3", "host4"]
usrs = ["usr1", "usr2", "usr3", "usr4"]
passwords = ["pass1", "pass2", "pass3", "pass4"]

def do_ssh_stuff(host, usr, pwd):
  ssh = paramiko.SSHClient()
  ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
  try:
    ssh.connect(hostname=host, username=usr, password=pwd)
    # Do the stuff on the remote machine

  except paramiko.ssh_exception.AuthenticationException:
    print("Failed on machine: " + host)

i = 0

for host in hosts:
   do_ssh_stuff(host, usr[i], passwords[i])
   i += 1
i = 0

事情有时似乎有效，有时我得到这个错误信息：

我尝试将transport.py中的横幅超时设置为15到30秒，但没有成功。

有人能指出我正确的方向吗？
