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)

这工作正常，但如果这是第一次登录机器，我会遇到问题:

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)

我如何从 python 中“输入”"is"，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。
