Sshd comes with sftp-server-Linux Enterprise Application-Linux server application information. The following is a detailed description. When using sshd to remotely log on to Linux, it is always troublesome. My files on Windows are not easily uploaded to the Linux server. In the past, I used to build a general FTP server software such as vsftp. Although vsftp is easy to use and has good performance, my Fedor

First, what is SSHSSH is the abbreviation for secure Shell, developed by the IETF Network Working Group, and SSH is a security protocol based on the application layer and transport layer. SSH is currently a more reliable protocol that provides security for Telnet sessions and other network services. The use of SSH protocol can effectively prevent the information leakage in the remote management process. SSH was originally a program on a UNIX system, and later expanded quickly to other operating
