ssh 192.168.1.10# scp /home/iso/********.iso root@192.168.1.***:/home/ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 a host key has just been changed. The fingerprint for the ECDSA key sent by the remote host is df:33:37:b6:7b:c9:e5:19:65:f7:38:ad:94:b2:9e:36. Please contact your system administrator. Add correct host key in /root/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /root/.ssh/known_hosts:1 ECDSA host key for 192.168.1.*** has changed and you have requested strict checking. Host key verification failed. lost connection
原因:
从报错信息看是因为目标主机key【比如重做系统或者还原】与已保存的key不同导致认证失败！ key算法为ECDSA，百度可知为椭圆曲线数字签名算法。详情请自查。解决方法：删除留存的秘钥
rm -f /root/.ssh/
