You enter the same passphrase with which you created the SSH private-public key pair, and the output of the command run on the remote destination server is seen locally back on your source server.
您可以输入与在创建SSH公私密钥对时同样的口令，且在远程目标服务器上运行的命令的输出可在您本地的源服务器上看到。
If an SSH public key changes or the pair is regenerated, all of the remote hosts will need the new public key in their authorized_keys file.
如果一个SSH公钥改变或重新生成密钥对，所有远程主机将在其authorized_keys文件中需要新的公共密钥。
