但是对应账号,我通过SecureCRT中SSH2去登录,是可以正常用密码登录的。

猜测是和最近添加了

【已解决】生成SSH公钥私钥和用私钥登陆远程服务器

的问题,看来果然是啊

ssh – Host key verification failed [rsync: connection unexpectedly closed] – Server Fault

但是不对啊。应该自动判断host的IP不同,不实用本地的私钥的啊

去看看:

很明显,本地没有此处的主机42.123.xxx.xx啊

试试:

ssh -v root@42.123.xxx.xxx

然后输入yes,输入密码,可以登录。

然后再去执行rsync调用ssh去上传文件,就可以了。

【总结】

此处rsync第一次调用ssh去上传同步文件到远程服务器,会报错:

Host key verification failed

原因:

好像是没有去ssh验证过,rsync无法识别?

总之,解决办法是:

命令行中去:

ssh -v root@42.123.xxx.xxx

然后对于:

Are you sure you want to continue connecting (yes/no)?

输入yes,会提示:

Warning: Permanently added ‘42.123.123.254’ (ECDSA) to the list of known hosts.

-》估计内部就是保存了密钥等信息,通过了服务器的ssh验证,本地保存了验证信息。

->接着输入密码,即可登录远程服务器。

->之后再去rsync调用ssh,就可以了。
