what is ssh2
The Secure Shell protocol version 2, or SSH2, specifies how a client can connect securely to an SSH server, and then use the resulting secure link to access the server's resources.Among other things, the client can run programs; transfer files; and forward other TCP/IP connections over the secure link.he SSH2 protocol is a descendant of the SSH v1.x series of protocols. SSH version 2 is standardized at IETF, and the vast majority SSH implementations now support SSH version 2.
The program SSH (Secure Shell) provides an encrypted channel for logging into another computer over a network, executing commands on a remote computer, and moving files from one computer to another.SSH provides strong host-to-host and user authentication as well as secure encrypted communications over the Internet.SSH2 is a more secure, efficient, and portable version of SSH that includes SFTP, which is functionally similar to FTP, but is SSH2 encrypted.SH provides strong host-to-host and user authentication as well as secure encrypted communications over the Internet.
