SFTP

SFTP简述

sftp（Secure File Transfer Protocol）是一种安全的文件传送协议，是ssh内含协议，也就是说只要sshd服务器启动了，sftp就可使用，不需要额外安装，它的默认端口和SSH一样为22。

sftp通过使用加密/解密技术来保障传输文件的安全性，因此sftp的传输效率比普通的FTP要低，但sftp的安全性要比ftp高，因此sftp通常用于报表、对账单等对安全性要求较高的场景。

用法

连接远程服务器：

sftp username@ip

回车之后输入服务器密码即可连接成功。

默认走22 端口, 如果不是要修改

sftp -oPort=60001 [email protected]

使用-o选项来指定端口号.

-oPort=远程端口号
