To connect via SSH, you will first need to download a SSH client. The most well known free SSH client is called PuTTY. You can download the PuTTY.exe program here or simply do a web engine search for "putty" to find another website that offers PuTTY for download.
You will need your SSH username and password available in the 1&1 Control Panel to connect. This user name and password is the same as the initial FTP user name and password that came with your package and can not be deleted. For more help, please reference What information is required to make a SSH connection?
Enter your domain name into the Host Name (or IP address) text box.
Select SSH as the Connection type under the text box.
Enter the domain name and select SSH
On the left-hand side of the window, click Data.
Enter your SSH user name into the Auto-login username text box. Your user name should start with the letter 'u' followed by numbers.
Enter your SSH username
From the left-hand side, click Session.
In the text box below Saved Sessions, enter a name for this configuration. It is recommended to use the domain name.
Click the Save button to save your configuration as this name.
Enter a name for the configuration and click Save
The configuration will be saved using the name chosen and you should now see this name in the list of Saved Sessions. In the future when you open PuTTY, you can simply click this name and click the Load button to load this configuration and then click the Open button to connect.
Click the Open button to connect via SSH.
The first time you connect to your webspace via SSH, the server will supply the SSH key fingerprint used for encryption. A warning appears that this key is not yet saved. Click the Yes button to save the key.
Once the key is saved, you will not receive this prompt when connecting to your webspace in the future.
The window will prompt you for a password to connect. The password will not be displayed on the screen nor will the cursor move when typing the password. This is normal. As a security precaution, no letters, asterisks or spaces are shown as you type the password to prevent bystanders from knowing the length of your password.
Type the password and then press ENTER.
Type the password and press Enter
