====== SSH keys ======

{{indexmenu_n>2}}
The connection with equipment is carried out via the SSH protocol.

Add a sudo user on this hardware. See [[dpi:dpi_components:dpiui:user_guide:admin_section:equipment_management:sudo_user:start|Sudo user]].

=== Configuration sshd ===

Check the **/etc/ssh/sshd_config** file and the **PubkeyAuthentication** property on the connected server.

If the **PubkeyAuthentication** property is missing, commented out, or set to **PubkeyAuthentication no**, then replace the property value with **PubkeyAuthentication yes**

<note important>After any changes to the **/etc/ssh/sshd_config** file, restart the sshd service with the command: <code>sudo systemctl restart sshd</code></note>

=== Authorized keys ===

Add a public key to a specific user's file on the remote server:
<code>/home/username/.ssh/authorized_keys</code>

For root user:
<code>/root/.ssh/authorized_keys</code>
