以前使用 SSH 登录公司服务器,挺好使!但是,今天它罢工了。
像往常一样,在终端输入命令登录服务器:
sudo ssh -l root 192.168.0.88
sorry,它提示信息如下:
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 51:58:c2:b3:d3:7a:e6:bb:20:bd:5b:37:a1:87:cc:de. 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:1 RSA host key for 192.168.0.88 has changed and you have requested strict checking. Host key verification failed.
linux 就是好,有了错误它会提示您错误在哪,根据打印信息,我解决了这个问题。
使用超级用户,为了进入 root/ 目录:
su
然后输入超级用户密码,进入/root/目录:
cd /root
查看该目录下面的所有文件,然后发现.ssh目录,进入即可!
ls -al cd .ssh/
在该目录下面有个文件 known_hosts,使用 vim 打开该文件:
vim known_hosts
删除里面的内容即可,如果你还怕出错,在删除内容之前可以备份!
再次使用 SSH 登录,出现下面的信息:
The authenticity of host '192.168.0.88 (192.168.0.88)' can't be established. RSA key fingerprint is 51:58:c2:b3:d3:7a:e6:bb:20:bd:5b:37:a1:87:cc:de. Are you sure you want to continue connecting (yes/no)?
yes 即可!搞定!
