# SSH (Secure Shell)

## Adding an SSH Zero Trust application

This article describes how to configure an [SSH connection](https://support.perimeter81.com/v1/docs/360008864000-managing-application-access) to a remote server. Make sure you are familiar with the server's authentication methods (username and password or SSH keys) and that you have a tunnel connecting your network and the environment that hosts the server before you begin.

- **Application Name****:** Enter a name of your choice.
- **Protocol****:** SSH
- **Icon****:** Use default or choose an icon of your own choice.
- **Host****:** Enter the internal IP address of the server to which you'd like to connect.
- **Port****:** 22
- **Network****:** Choose the network that contains the gateway from which you created a tunnel to the environment that hosts the server you'd like to connect to.
- **Display Application Icon at Login Screen****:** Choose according to your preference.
- **URL Alias (Optional)****:** See [Certificate Manager](/v1/docs/360025534473).

- **Authentication****:** If disabled, you'll need to enter your credentials as predefined on the server with every login.
- **Username and Password:** Enter one set of credentials as predefined on the server. You will not be required to enter any parameter with the login.
- **Private Key/Username/Passphrase:** Enter your RSA-SSH key under Private Key with a correlating username (according to user settings predefined in the server). Note that a certificate typically starts with a prefix and a suffix such as the following:

```shell
-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----
```

If a passphrase is a set along with SSH key, enter it as well, otherwise leave blank.

- **Access Groups****:** State the names of the user groups which have access to the SSH application.
- **Policy****:** Leave blank, or choose a policy that was previously created and matches your needs.

1. To connect to the application enter the application FQDN in the URL line of your browser or connect through the **Management Platform**.
