当我ssh到一台机器时,有时我会收到此错误警告,并提示说"是"或"否".从自动ssh到其他计算机的脚本运行时,这会导致一些问题.
警告信息:
The authenticity of host '<host>' can't be established.
ECDSA key fingerprint is SHA256:TER0dEslggzS/BROmiE/s70WqcYy6bk52fs+MLTIptM.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'pc' (ECDSA) to the list of known hosts.
有没有办法自动说"是"或忽略这个？
使用简单的防火墙ufw,我可以将端口/服务设置为拒绝和拒绝.
例如:
ufw deny www
ufw reject www
有人可以向我解释两种方法之间的区别吗？
