  • 1.  Disable SSH Version 1 HP ProCurve

    Posted Aug 03, 2017 10:45 AM

    Hi,

    I need to disable SSH version 1 on my HP Pro Curve Switch. All the commands I have tried so far have not worked. Some of the commands I have tried are:

    undo SSH Server Compatible-ssh1x

    no SSH Server Compatible-ssh1x

    Does anyone have any suggestions

    The Switch details are as shown below:

    HP J4904A ProCurve Switch 2848
    Firmware revision I.07.31
    Switch# show ip ssh

      SSH Enabled            : Yes
      SSH Version            : 1-or-2
      IP Port Number         : 22
      Timeout (sec)          : 120
      Server Key Size (bits) : 512

      Ses Type     | Protocol  Source IP and Port
      --- -------- + --------- ---------------------
      1   console  |
      2   ssh      | SSH v2   
      3   inactive |
      4   inactive |


    #V1
    #ssh
    #Version1
    #disable

    Hi,

     

    No IP SSH will turn of SSH all together. Is your idea to have SSH v.2 enabled?

    Thanks for the reply,

    From what I can see, SSH V2 is already enabled. The problem is that SSH V1 is also enabled leaving the switch vulnerable to attacks as identified by our recent pen tests.

    Any ideas on how to disable V1 but leave V2 enabled?
