This approach is used when the destination server is not accessible to the local host - for example, due to firewall filtering - but it is accessible to the SSH server.

Local port forwarding enables connecting from your local host - running the SSH client - to a destination server via the SSH server.

The three types of SSH tunnels are as follows: SSH tunneling enables more interesting types of use cases.

SSH tunnels, on the other hand, provide the means to patch together streams of data between processes running on the localhost and the remote host. In most cases for this type of use case, the port being used is the default SSH port 22. In this example, a typical use case for SSH, user example-user is logging into a terminal session with the host at. The first time an SSH connection is made to a remote host, the option to authenticate the remote host's public key is available. When making an SSH connection, the server and client exchange public key information and negotiate a secure session key for encrypting SSH data exchanges. SSH can be used with either domain names or IP addresses, so if the host named has the IP address 192.0.2.127, the following command has the same effect as the command above: ssh -p 2222 This only works if the remote server is configured to listen for requests on that port. The -p option flag is used to specify port number 2222 on the remote server, which causes SSH to send traffic to port 2222 instead of the default port 22. SSH servers can respond to session requests on other ports as well - for example: ssh -p 2222 This command opens a terminal session on the remote server using port 22, the default port for SSH. Credentials for a user login with permission to access the remote server.įor example, a terminal session on a remote host called with the user ID example-user is initiated with this SSH command: ssh.

Although GUI versions of SSH like PuTTY for Windows can also be used, learning to use the command-line version is a skill that can be applied to almost any modern OS. SSH is usually started by entering the ssh command.

Access to an SSH client on the local machine.

This remote host must have an instance of the SSH server program, sshd, running.

The domain name or IP address of the remote machine to access.

Starting an SSH session requires the following: PuTTY is an open source GUI version of SSH available for Windows. OpenSSH was incorporated into Windows versions 10 and newer for use in the command line. OpenSSH is an open source command-line implementation of SSH that was originally developed for the OpenBSD OS but is now available on almost all Unix-based OSes, including Linux and macOS.

SSH client software is almost always available on modern computers. SSH depends on the exchange of public keys between client and server to enable authentication of the user and encryption of the data being transmitted over the SSH connection.

In this case, a user has the SSH client software to securely connect to another host running an SSH server. The simplest use case for SSH is to log in to a remote host for a terminal emulation session. If hackers gain access to a host running SSH on an organization's internal network, they can use SSH on that host as a secure pipeline for exploiting private network services, so it is vital to understand how SSH access can be used for good - and for evil. SSH port forwarding enables two communicating systems to exchange data securely across the internet and through firewalls. SSH tunneling, also known as SSH port forwarding, is how SSH tunnels network traffic through application ports from the localhost - the computer physically present - to a remote system or vice versa.
