我在云服务器中已经搭建好filezilla服务器端,这边的客户端也安装好了,也能正常连接上,可是当我要传输数据的时候却提示我以下错误
命令: CWD /
响应: 250 CWD successful. "/" is current directory.
命令: TYPE A
响应: 200 Type set to A
命令: PASV
响应: 227 Entering Passive Mode (140,143,138,173,194,134)
命令: STOR 腾讯云FTP用户名与密码.txt
响应: 550 Permissio
我是个新手求大侠们指点:
刚弄的云服务器 今天ssh登录时偶然发现root密码登录后提示:
Last failed login: Fri Dec 15 10:41:37 CST 2017 from 51.15.220.221 on ssh:notty
There were 49 failed login attempts since the last successful login.
请问这是安全隐患吗?是怎么形成的?需要怎么处理?
