HP J9773A 2530-24G-PoEP Switch - ssh login fault

    Hi

    When I login with ssh to the swicth then I see the orange fault indicator and the switch seems to reboot.  This happens everytime just after I type the password and presses enter?

    I'm actually able to do an scp filestransfer using the same username and password - with no problem.

    I have regenerate ssh rsa keys and it didn't help.

    The switch came with software version YA.16.04.0008 and I upgraded to version YA_16_06_0006 but the problem persists. I then downgraded to version YA.15.17.0009 and this version has no problem.

    Is this a bug or do I need to do some extra configuration in version YA.16.xx to fix this?

    Config:

    ----

    hostname "SW01"
    console idle-timeout serial-usb 0
    logging 10.24.2.10
    timesync sntp

    I found the issue :-)

    I used another ssh client and it worked fine. The issue with the ssh client that caused the switch to spontaneous reboot seems to be in my ".ssh/config" where I use "RemoteForward 52698 localhost:52698" for my rmate editor.

    If I ignore "RemoteForward 52698 localhost:52698" then I have no problem with ssh login.

    What I know of is that this issue has affect on version YA_16_06_0006 and YA.16.04.0008 - so maybe from version YA.16.xx

    There is no issue in version YA_15_17_0009.

    I would suggest that the switch should just ignore ssh RemoteForward like most other equipment. I think it's rather critical that somebody malicious or by accident can bring the switch to spontaneous reboot?

    Can somebody comment on this?

    Cheers, Martin
