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. Depending on your use case, these other types of SSH tunnels may suit your needs.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. In addition to SSH tunnel proxy servers, there are also SSH tunnels and reverse SSH tunnels. Ssh -L 8888:159.223.188.83:80 Other SSH Tunnel TypesĪ few different flavors of SSH tunnels exist. Functionality will be the same whether or not you include it

The default SSH port is 22, so you don’t need to specify that either.

You don’t need to include localhost of the local machine because that is the default.

159.223.180.93 is the public IP address of the proxy serverĪfter executing the SSH tunnel command, the remote service at 159.223.188.83:80 will be accessible on the local machine at localhost:8888 via the proxy server at 159.223.180.93.

root is the SSH user of the remote server.

159.223.188.83 is the public IP address of the remote service.

8888 is the port that the local machine will listen on.

localhost is the host on the local machine that will bind to the remote service.

This can be a different port, but needs to be open

-p 22 is the SSH port of the remote server.

-L forwards local connections to the remote side.

ssh -N -L -p 22 localhost:8888:159.223.188.83:80 -N is a flag to just forward ports and not execute remote commands The command for establishing an SSH proxy tunnel looks like this. Since you have SSH access to the proxy server, you can send the remote service over the SSH port via a tunnel. Pin A visual example of an SSH proxy tunnel and the associated command You want to access this service from your local computer, but the only way to access it right now is from another server (i.e. Let’s say there is a service on a remote server that is running on port 80 (the private server).
