This guide explains how to connect to your Web Hosting using an SSH key.

Prerequisites

1. Create an FTP + SSH account from the Infomaniak Manager.
2. Create an SSH key with a secure algorithm, for example ed25519:

   • ssh-keygen -t ed25519

     because with an rsa key (ssh-keygen or ssh-keygen -t rsa), the connection will be refused and the following error will be returned in verbose mode:

     debug1: send_pubkey_test: no mutual signature algorithm

Upload the SSH key

To do this:

1. Log in to the server via SSH (need help?).

2. Go to the root of your hosting:

   cd ~

3. Create the directory « .ssh»:

    mkdir .ssh

4. Change the permissions of the .ssh directory to CHMOD 700.
5. Create the authorized_keys file and paste your public SSH key on a single line (important).
6. Change the permissions of the authorized_keys file to CHMOD 600.
