sun:~ sun$ scp /Users/sun/Documents/apache-tomcat-7.0.86.tar.gz root@ip哦:/mnt @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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 RSA key sent by the remote host is SHA256:u/m4HwxSpoS/EshBWK136Ek87rtCaOpk6iQKZ3TcxvM. Please contact your system administrator. Add correct host key in /Users/sun/.ssh/known_hosts to get rid of this message. Offending RSA key in /Users/sun/.ssh/known_hosts:5 RSA host key for ip哦 has changed and you have requested strict checking. Host key verification failed. lost connection sun:~ sun$ cd /Users/sun/.ssh/ sun:.ssh sun$ ll total 16 -rw-r--r-- 1 sun staff 399 4 23 2016 authorized_keys -rw-r--r-- 1 sun staff 1925 4 25 10:12 known_hosts sun:.ssh sun$ rm -rf known_hosts
大概是因为 ip哦 的主机密钥改了,而本机使用的还是原来的公钥与其匹配,因此会出现错误。有人问不是我们使用密码么,嗯,原因是这样,一旦使用本机ssh连接过目标机,则会在目录下生成目标机的公钥,以便下次可以直接使用。所以,我们可以把该文件下 ip哦 对应的公钥删除掉
