@jlehtone (OT) Some software (such as OwnCloud) gets a bit stroppy if you use http rather than https. Other than that, yes you are correct.
By "signed by public CA" I did imply making your own CA and certs with it.

Re: Hardware Question - S.M.A.R.T. reports disk failure imminent

I don't think you can test this with 'dd' because the re-mapping will be at a lower level and 'dd' will just skip over it. Sector reallocation occurs only when writes fail. The dd writes. The SMART counters before and after that dd would have been interesting; how many reallocs did the dd invoke? T...

Re: how to change web "http" to "https" to secure information?

Then again, if you have private TLD, then you presumably all clients that can access that name are under your control and therefore you have no need for certificate signed by public CA.

The OP case (company and customers) surely has public TLD.

Re: CentOS 7, Kernel 5.12, Virtual Box 6.1 -can't start Virtual Machine

gcc: error: unrecognized command line option ‘-mrecord-mcount’ You are building with system's gcc. I don't think that you can compile kernel with that version any more. Install 'devtoolset-10-toolchain'. Then enable that SCL: scl enable devtoolset-10 bash Within that bash session you have access to...

Re: CentOS Stream 8 CVE 2021-33909 update?

I don't have Stream; did get the list of kernels by browsing that repo URL. Should have mentioned that "Classic" has 4.18.0-305.10.2. I just have no idea why a copy is in Stream directory too. When Red Hat "shifted focus of CentOS Project", there were explanations of how things will be. The usual fl...

Re: Install of python3-libs-3.6.8-13.e17.x86_64 conflicts with file from package phython36

When CentOS Linux 7 was originally released, it had python2 but no python3. (The python2 is a crucial system component.) Later, third-party repositories (and Red Hat Software Collections) did package python3 for CentOS 7. The "IUS" is a third-party repo. Eventually, python3 was packaged for base rep...

Re: Cann't access website link

Your program, ' node ', listens only 127.0.0.1 :5601. Not 192.168.186.10:5601 , nor *:5601 . You have to configure your program to listen where you want. You did follow some "guide". It told you to listen only 127.0.0.1:5601. Did it have a (security) reason for that? Alternative: If you can ssh to t...

Although already permitted 5601 port on ELK server.
Did you:
* Make the service listen to that port
* Make firewall grant access to that port for the client
* Make SELinux allow service to access that port
