SSH登陆错误 WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
[root@localhost ~]# ssh 192.168.10.88
@ WARNING:
REMOTE HOST IDENTIFICATION HAS
CHANGED!
@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle
attack)!
It is also possible that the RSA host key has just been
changed.
The fingerprint for the RSA key sent by the remote host is
b6:0c:41:43:60:79:eb:05:9e:c9:72:1d:a0:41:9a:50.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this
message.
Offending key in /root/.ssh/known_hosts:5
RSA host key for 192.168.10.88 has changed and you have requested
strict checking.
Host key verification failed.
因为在本地机器上曾经用SSH登录过这台远程计算机,因而留下了known_hosts的记录,在远程计算机重新安装系统后不能够通过鉴权.gedit ~/.ssh/known_hosts 进入此目录,删除192.168.10.88的相关rsa的信息即可.
二、The authenticity of host '192.168.2.108 (192.168.2.108)' can't be
established.
wzhnsc@wzhnsc-Ubuntu:~$ ssh 192.168.2.108
