Linux hosts built by SCS Computing Facilities allow remote login via SSH to users on the system by default.
Either of these clients can be used to access AFS from a Windows computer by SSHing to a Linux computer that mounts AFS, like linux.gp.cs.cmu.edu. The WinSCP client is also installed by default for users seeking a graphical interface for transferring files over SSH using SCP. Windows: Windows machines provided by SCSCF will include the command line SSH client PuTTY by default. macOS: The OpenSSH client is installed by default on all systems running macOS.
If there is no SSH client present, see the package management documentation for the appropriate Linux distribution for notes on how to install an SSH client. Most other Linux systems should also have an SSH client installed by default. Linux: Linux machines provided by SCSCF have the OpenSSH client installed by default. SCS Computing Facilities includes SSH clients by default on all Linux, macOS and Windows systems that we build. In SCS, we use the OpenSSH implementation of the SSH protocol suite. Additionally, SSH supports a range of features including tunneling arbitrary TCP ports and X11 connections. SSH is typically used to log into a remote machine and execute commands or to perform secure file transfer using the associated SFTP or SCP protocols. There is no exposure of valid credentials, if a server has been compromised.Secure Shell (SSH) is a cryptographic network protocol which allows for data to be securely exchanged between two computers using an encrypted channel. It is more convenient and secure than login ids and passwords (which can be stolen in middle). SSH is key based authentication that is not prone to brute-force attack. SSH creates a route and all the encrypted data are transferred through it with no security issues.Server after receiving this data verifies the local computer.This data is unlocked by the private key of the system and is send to the server.
This encrypted code is send to the local computer.If so, the server then creates a new secret key and encrypts it with the public key which was send to it via local computer.Server then identifies if the public key is registered.Public keys from the local computers (system) are passed to the server which is to be accessed.It uses asymmetric cipher for performing encryption and decryption. Session key – Used when large amount of data is to be transmitted.Host Key – If public key and private key are on a remote system.User Key – If public key and private key remain with the user.Private key – Stays in computer, must be protected.Public key – Everyone can see it, no need to protect it.
It allows you to connect to a server, or multiple servers, without having you to remember or enter your password for each system that is to login remotely from one system into another. In other words, it is a cryptographic network protocol that is used for transferring encrypted data over network. SSH(Secure Shell) is access credential that is used in the SSH Protocol.
