you need to use CLI, thos model is particular cause you can t activate telnet or SSH in GUI mode so you need to follow this :
Re: How to Enable Telnet and SSH on HPE 1920s OfficeConnect
- download startup-config from GUI
- edit it, insert ip telnet server enable before configure
- upload it as startup-config in GUI
- reboot switch
- telnet into it with configured admin account and then enter sequence of commands to generate crypto keys and run ssh daemon
enable
configure
crypto key generate rsa
crypto key generate dsa
exit
ip ssh server enable
ip ssh protocol 2
write memory confirm
quit - use ssh (look at step 5) and disable telnet if you need like
enable
no ip telnet server enable
write memory confirm
quit
I guess you can enable SSH for all recent OfficeConnect models 1820 or 1920S or 1950 the same way!
It would be more secure to use public key auth instead pwd auth, but theres no aaa authentication ssh login public-key in these switches.
