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

Prerequisites

1. Create a FTP + SSH account from the Infomaniak Manager.
2. Create an SSH key with a secure algorithm, e.g. 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

For this:

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

2. Go to the root of your hosting:

   cd ~

3. Create the « .ssh» directory:

    mkdir .ssh

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