Connecting to Your Webspace via Secure Shell (SSH) using PuTTY

For Linux Webhosting and Managed Dedicated Server packages with Shell (SSH) Access

In this article, we will show you how to connect to your webspace using the program PuTTY.

PuTTY is a free program for Windows operating systems that allows SSH encrypted connections to the command line (shell) of a remote server. This makes it possible to execute commands directly on the remote server.

  • You have set up a password for your SSH user or the FTP main user (the FTP main user is also your SSH user).

  • Download PuTTY to your computer and run putty.exe.
  • For Host Name (or IP address), type the host name displayed in 1&1 IONOS . This is automatically created when your package is set up and has the form or
  • Make sure that Connection Type: is set to SSH and leave the port at 22.
  • Save the settings by assigning a name such as WebsiteSSH under Saved Sessions and then clicking Save so you don't have to re-enter this data each time.
  • Then select the currently saved connection and click Open to start the session.
  • The first time you connect, the fingerprint of the hosting server is displayed. For security reasons, compare it with the fingerprints listed here and confirm it. These are the current server SSH fingerprints - they can be displayed differently depending on the settings of your SSH program. Here you can see the most common representations:

Please Note:

If necessary, we will change these host keys for your security on our servers. In this case, your SSH program will issue an error message and notify you of this fact. If this happens, please compare the updated fingerprint here on this page and confirm.

Also, the SSH login is only possible with the SSH user or the FTP main user (since identical). Additionally created FTP users do not include SSH access.

  • The command line is now opened in a new window. You can now log in. For login as, enter your SSH user name and press Enter. A second line appears. Enter your password and press Enter.

Hint: For security reasons, the password is not displayed during input, but you can correct any mistypes with the backspace key.

You are now connected to your webspace via SSH.

You can now use the command line to edit configuration files, for example, with the Vi Editor. This article describes how to create and edit files with vi-Editor via SSH.
