Switches 'HPE OfficeConnect 1920S' - Enable SSH / TFTP Services

Please note that suggested solution (inserting "ip telnet server enable" into startup-config file and then enabling ssh) works only till firmware version PD.02.06.stk (including).

When upgrading to newer firmware it seems that telnet and ssh servers have been removed and the suggested solution does not work anymore.

Well, actually you CAN enable telnet and ssh. It's completely unsupported, but anyway:

1. Update firmware to latest version, I used PD.02.06.stk.
2. Go to Maintenance -> Backup and Update Manage, click download and select startup-config. Download that file.
3. Edit startup-config file (it's a text file, use any text editor), insert "ip telnet server enable" before config statement, like this:

!Current Configuration:

4. Upload startup-config file as startup config
5. Reboot switch and telnet to switch ip
6. Login and enable ssh:

Here is original thread: https://community.hpe.com/t5/Web-and-Unmanaged/How-to-Enable-Telnet-and-SSH-on-HPE-1920s-OfficeConnect/td-p/6988775 , today I enabled telnet on my 1920S using this trick.

See the following link: https://glazenbakje.wordpress.com/2012/08/21/hp-v1910-secret-commando-list-how-to-enable-it/

Both the V1910 and the (old) 1920 have a technician's CLI, which is completely unsupported, but works good enough. Keep in mind that this is not about the 1920S. I just ordered a demo model of the 1920S and will get it on monday. Will test if the CLI is accessible then.

18xx and 19xx are "smart-managed" or web-managed only, no telnet, no SSH. Some 1920s have a minimal serial/USB console though. The switch has TFTP and SFTP clients but no server.

I've looked into 1810 switches a while ago (how to automate config backups using curl). These SOHO switches apparently use firmware made by the chipset manufacturer that has been branded by HP. 1810v1 and 1810v2 differ significantly by site structure and backup file format, so that they're actually two different devices.

Depending on what you're trying to do, you might be able to accomplish some automated management using curl, but if you want a real console interface you'll need to replace the switch.
