當你連到一個沒連過的SSH server

或 某台你連過的SSH server HOST KEY變更

你連過去會出現

The authenticity of host '10.10.10.10 (10.10.10.10)' can't be established.
RSA key fingerprint is 1a:3b:91:73:81:5a:c3:4c:7a:39:7a:4f:0b:27:b1:e0.
Are you sure you want to continue connecting (yes/no)?

很煩對不對??

 解法滿多的

1. 從client端

當你client端要連過去時

#ssh  -p [Server's Port#] -o StrictHostKeyChecking=no 10.10.10.10

2.改client上的設定

edit /etc/ssh/ssh_config or ~/.ssh/config

在最上面新增

Host 10.10.10.*   <---  任意你想要的網段

   StrictHostKeyChecking no
   UserKnownHostsFile=/dev/null

改好後，只能用IP連喔......

ssh 10.10.10.10
password:
