Connect using SSH key

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, 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

To do this:

1. connect to the SSH server of your hosting

2. go to the root of your hosting:

   cd ~

3. create the directory ".ssh":

    mkdir .ssh

4. change the rights of the directory ".ssh" to chmod 700
5. create the authorized_keys file and paste your public SSH key on a single line (important)
6. change the rights of the authorized_keys file to chmod 600
