Missing SSH config page

Is it just me; I’m missing the Luci SSH configuration page (system-administration-SSH access/SSH-keys).
Trying to reach it directly gives:“Unable to dispatch: /cgi-bin/luci/admin/system/admin/dropbear”.
Is this by design ? (TOS4.0.3)

Yes, this is by design - dropbear is by default replaced by openssh-server on turris devices.

Ah, I see. Thanks for this information.
Is it known why CZ.nic choose for openssh and not the standard dropbear?

Basically Dropbear is an implementation of the ssh protocol with reduced functions for embedded devices. Turris chose OpenSSH which is the most complete implementation.
