Background
Secure Shell (SSH) is an encrypted network transport protocol, and can provide a Secure transport environment for network services in an insecure network. SSH enables a connection between an SSH client and a server by creating a secure tunnel in the network. While any web service can be securely transported through SSH, the most common use of SSH is to log on systems remotely, typically using SSH to transport command line interfaces and execute commands remotely. The most frequently used applications are Unix-like systems, but the Windows operating system can also use SSH to a limited extent.
An SSH character terminal access is usually deployed in a graphical operating system in a rich client form, and software supporting the SSH character terminal includes Putty, SecureCRT, Xshell, and the like on a common Windows operating system.
Common rich client terminal character terminal software creates an independent remote SSH operation process each time when accessing an SSH server, and the two SSH operation processes are completely independent and cannot share pictures and operation data. Therefore, the character terminal screen cannot be operated by multiple persons in cooperation.
The rich client character terminal software is limited by a deployment platform and does not have the capability of crossing multiple platforms. The common rich client terminal software also has no auditing and after-the-fact backtracking capabilities in the operation process, and a few rich clients also only have the function of locally storing part of operation data. As audit data, it is easily tampered with by a person.
