没有真实性验证的python ssh

Question

我正在这样的AWS机器上远程运行命令：

key = 'myPemFile.pem'
target = <machine_ip>
cmd = 'ssh -i ' + key + ' ubuntu@'+target+' "nohup myprog + ' >& /dev/null < /dev/null &" &'
proc = subprocess.Popen(cmd, shell=True,  stdout=subprocess.PIPE)

这可以正常工作，但是如果是第一次登录计算机，则会出现以下问题：

The authenticity of host '144.224.18.97 (144.224.18.97)' can't be established.
ECDSA key fingerprint is e2:4e:...:e3:73:07.
Are you sure you want to continue connecting (yes/no)

如何从python中“输入”“是”，或者使用标志告诉ssh不要问这个问题？

Answer 1

尝试将-o StrictHostKeyChecking = no传递给ssh命令。
