SSH

The device supports SSH-2 connections with either public key authentication or user
name and password. The "login" must be enabled for SSH. Users and passwords can be
stored locally or retrieved via a radius server. If you want to use SSH in a terminal, Activ-
ate echo should be enabled.

Public Keys

The following public keys are accepted:

Key type

Length

RSA

2048, 4096

ECDSA

256, 384

Generation with PuTTYgen

Generated keys can be copied directly from e.g. PuTTYgen,

and inserted into the Configuration - Console input field. Public keys are accepted in
SSH2 or OpenSSH format.

Generation with ssh-keygen

The tool ssh-keygen is mostly shipped with Linux and Windows to generate SSH keys.
