Unable to install Symantec Management Agent on Red Hat 8 Enterprise Workstation

IT Management Suite


Unable to install the Symantec Management Agent x64 bit on a Red Hat 8 Enterprise Workstation.  The customer has tried the Symantec Management interface as well as manually installing it.

Keep getting the following error when trying to push:

// Failed to connect (SSH) - Exception from HRESULT: 0x8000EE06
// Computer might be switched off.
// You may also need to check the credentials supplied, the firewall rules on the computer and its SSH or telnet configuration.

The customer has confirmed that SSH works (testing with Putty) and that he can log into the Red Hat 8 Enterprise Workstation using SSH and the credentials he is using are valid.  He is using the root credentials.  

The usual ports are open (based on our KB 184952 "Ports and Protocols for Symantec IT Management Suite (ITMS) 8.5 and 8.6"):

TCP ports open: 22, 80, 53, 443,1024, 52028, 1433, 389, 137, 3476

UDP ports open: 22, 53, 137, 138, 389, 445, 1024, 1433, 138, 3476, 1434, 52028, 52029, 65536


This is the error the customer gets when trying to install the Symantec Management Agent (they are taking the text directly from the Linux machine they are attempting to install this to):

[root@sc1-lab-groton Downloads]# ./aex-bootstrap-linux

ITMS 8.5, 8.6


Known issue. If FIPS is enabled, the installation process has been blocked.


This issue has been reported to our Broadcom Development team. A fix has been added to our next major ITMS release (currently 8.7 version)

In order to validate if FIPS is enabled, please get output of following command:

  1. sysctl crypto.fips_enabled

If FIPS is turned on, the output should looks like this:

[root@sc1-lab-machine ~]# sysctl crypto.fips_enabled

crypto.fips_enabled = 1

As a workaround until the fix is available is to:

  1. Disable FIPS

    To turn off fips:
    As root:
    #fips-mode-setup --disable

    To verify fips is off:
    #fips-mode-setup --check

  2. Install the Symantec Management Agent
  3. Enable FIPS
