Are you sure that new HPE OfficeConnect 1920S will let you to enable SSH/Telnet services (if included into the system operating system at all) and thus use them for system configuration?

AFAIK - officially - published supported management methods (Features) are actually: HTTP, HTTPS and SNMP (reference: here).

Hi, I have this issue too. I can't find a way to enable SSH. The Config Guide says "Session Type Shows the type of session, which can be Telnet, Serial, SSH, HTTP, or HTTPS." (page 33), Don't know why the guide mentions SSH if it couldn't be enabled. Maybe it should be enabled in OS first. Regards.

I am having the same problem here. I need to get access trough telnet or ssh, but it just don't exist!! The interface on the http page is horrible, it's missing a lot of functions. The OfficeConnect 1920s series are just horrible.

SSH and Telnet not working for me either.

 

Can't figure out how to save changes on these switches.  Very frustrating.  I will not be buying any more of these switches.

Re: How to Enable Telnet and SSH on HPE 1920s OfficeConnect

Hello @MathiasD and @JoMa1, the HPE OfficeConnect 1920S Switch series (Embedded Linux operating system based) CAN'T BE compared to the superseded HPE OfficeConnect 1920 Switch series (Comware 5 operating system based): the HPE OfficeConnect 1920S Switch series is Web Manageable only Switch AFAIK...so looking for alternative management modes (Telnet or SSH, supported by the older 1920) is a dead end road.

IMO related documentation must be corrected/redacted to reflect exactly the features that HPE OfficeConnect 1920S Switch series is now supporting...but this subject deserves another thread.

Anybody tried the latest PD.01.07 Firmware build (December, 21st 2017)? see here.

Just want to clarify my issue.  Don't use Chrome to manage the switch, you don't get the "Apply" button at the bottom which was my issue when trying to save configs.  Support mentioned that any browser but Chrome works fine.

I just updated mine to 01.07, telnet and SSH still don't work.  They added a new option under Maintenance to manage your config files which is nice.

I also updated to 01.07 and now the configuration files option is much better. I'm still afraid of keeping this switch on my netowrk., but it's getting better now, just learnead the basic configurations I need.

I know I am dredging this up, but I figured a small workaround, you can download the configuration file, edit it manually, and then re-upload it.

Just curious what lines you put into the downloaded config. I'm trying to figure out the same thing and any remote CLI access would be handy (seriously, how hard is it to bake that into the firmware?).

  1. download startup-config from GUI
  2. edit it, insert ip telnet server enable before configure
  3. upload it as startup-config in GUI
  4. reboot switch
  5. 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
  6.  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.

I was able to enable the Settings as instructed, but i couldn't get the startup config from the Switch:

 

C:\pscp.exe -scp -l backup -pw backupuser -2 192.168.1.101:startup-config C:\Switchconfigs\%date%\switch1.cfg

 

Connecting to 192.168.1.101 port 22

Using SSH protocol version 2
Doing ECDH key exchange with curve Curve25519 and hash SHA-256
Server also has ssh-dss host key, but we don't know it

Any suggestions?

The Script is working fine for old 1920 Switches. The file name at those ones are startup.cfg.

Where do I insert this command? I was able to download the startup config but I don't have anything that says configure. I'm working with a default config out of the box.

Re: How to Enable Telnet and SSH on HPE 1920s OfficeConnect

It seems that there is no way to turn SCP on in cli.....
So, I would try to sniff HTTP traffic::

  1. Download, Install and Run Wireshark to sniff HTTP traffic between PC and switch.
  2. Open webbrowser login to switch via HTTP and download config file.
  3. Analyze sniffed HTTP traffic and find the GET request that initiated download.
  4. Try wget/curl Linux utilities or write your own script (python/perl etc..) to download config the same way as your browserd do.

When (if) you succced, you can configure HTTPS on your switch and use HTTPS in your script instead of HTTP for security..
