SCOM agent discovery for linux agent RRS feed

  • Question

  • Hi All

    Am trying to discover linux server version 7 for SCOM 1801. Discovery through console failed, so i have installed the agent manually.and update the cert with the server name.

    When am trying to sign the cert through SCOM , am getting below error.

    WS-Management cannot process the request. The operation failed because of an HTTP error. The HTTP error (12152) is: The server returned an invalid or unrecognized response .

    Any idea on this ?

    Error 12152 trying to do install

    A few things to check:

    • Make sure the DNS configurations are correct (Forward & Reverse).
    • Make sure the required firewall ports are open.

  • Hi,

    For this problem, we may consider the following:

    1, At Linux side, the hostname and domain name in the certificate should match the one in step above. Also, the hostname of Linux computer should match either.
       use the following command to check the certificate:
       openssl x509 -noout -in /etc/opt/microsoft/scx/ssl/scx.pem -subject -issuer -dates
       If it is incorrect, we can change it via the following command:
       /opt/microsoft/scx/bin/tools/scxsslconfig -f -h <hostname> -d <domain.name>

    2, make sure port 1270 and SSH port (22 by default or user-defined) of Linux computer is open


    Hope the above information helps.
