If not, you can install the client on a RHEL system using your package manager: $ sudo dnf install -y openssh-clients Most Linux and macOS systems have the openssh-clients package installed by default. You can then access the server with most terminal applications that support the SSH protocol (GNOME Terminal, Konsole, PuTTY, mobaxterm, and others). If it's not present, install OpenSSH on a RHEL server using your package manager, and then start and enable it using systemctl: $ sudo dnf install openssh-server OpenSSH is usually installed by default on Linux servers. This process encrypts traffic exchanged between the server and the client. Because passwords and usernames can be brute-forced, it's recommended to use SSH keys.įor an SSH client and server to establish a connection, the SSH server sends the client a copy of its public key before allowing the client to log in. You can connect using a password or a private and public key pair. To initiate an SSH connection to a remote system, you need the Internet Protocol (IP) address or hostname of the remote server and a valid username. SSH uses port 22 by default, but you can change this to a different port. The sshd daemon, which runs on the remote server, accepts connections from clients on a TCP port. The OpenSSH suite contains tools such as sshd, scp, sftp, and others that encrypt all traffic between your local host and a remote server.

There are two forms of remote access on RHEL and most Unix and other Linux systems: In the modern world, where working from home has become prevalent and most organizations use cloud systems, it's not practical to always be physically at a server to perform an administrative task.
