| 关键词： nbsp HOST 密钥 key 错误 CHANGED known hosts ssh POSSIBLE |
今天用scp命令复制时，提示如下错误： @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 25:ab:2e:55:30:11:a0:84:d8:45:2f:5b:e2:47:eb:1e. 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 192.168.1.240 has changed and you have requested strict checking. Host key verification failed. lost connection 开始我以为是命令错误，仔细一看，原来是密钥验证错误，可能是我的账号信息做过更改。 找到该用户家目录下的如下的ssh连接文件夹： 1. cd ~/.ssh/ 2. vi known_hosts 3. 找到和远程主机ip一致的密钥保存信息，直接dd删除，然后：x保存退出 4. 重新连接，输入密码，发现连接成功 问题解决 |
