Ok, so this needs updated on my server. I have a screen shot but not sure if I should post if this creates a security breech for this server. I doubt it, but to be safe I will not post it yet. Keep in mind this shit makes me nervous as hell. Almost like playin with electricity. (I hate that) Anywho, it says I should run the update from a command line, which I understand. I need to download a program that is talked about here in this board and configure it to access my server and go from there.

Keep in mind I am on a vps. So I am not sure I should even do this. What I did was go into the security advisor in WHM and ran a scan to see what problems I had. This is one that comes up on pretty much every server I have ever had. So, do I update it or not. Remember my nerves please lol.

Your panel should have the option to allow you to update your OS.
It should also have an option to access the command line as the root user else you sudo root.

What are you using CentOS, Ubuntu, Windows?

You should be updating your OS on a regular basis.
ie. check at least every few weeks or less.

I just read in one of the other threads something about CentOS with yum installed.
If that's the case then you can usually update using the command line with:
yum update

or if you are not set as root by default then it is (prompted with root password):
sudo yum update


It is centos 6.9 I will post the screen shot for a bit than take it down.


The -y is so it does not prompt you with any yes/no questions but it's the same command.
Just run it, nothing to be worried about.


Would this do the same thing. I just updated WHM and cpanel from WHM. Now I find this button. Would that update the kernal the way it should.


I can't find a command line in WHM so I guess I need software to do this.

Your server host panel (not your control panel) may have command line access.
Perhaps check that first prior to the info below but eventually you will need to learn how to do what I am instructing.

I use pUTTY but there are other terminal command line platforms.
I think Skhilled uses something else that he mentioned in the past.

putty download:

If you set something like that up it has to be secured else hackers/bots will attempt to access it.
It needs SSL encryption.

Even though some tutorials suggest not to use a passphrase for the ssh tunnel I will suggest that you do.
This way there are 2 layers of p/w protection to access the terminal (key & passphrase).
When you learn a bit more you can change the port access but at your level I suggest sticking with port 22 for now.

install putty ref.

setup ssh tunnel & generate keys for putty:

After setting up the SSH tunnel make sure you first open a second putty window and test the new tunnel settings before closing the first opened putty page. This way you can make sure you have it set correctly prior to logging out of the initial terminal window.

SSH Port:
You can change your SSH port to make it's more secure. This step can be done at a later time when you are more comfortable with the command line.  Make sure to heed my warning and test in a second open window after making changes so that you know you can log in.


.. ensure you edit the file & do the firewall changes else it will not allow you to use your terminal.
Also do not forget to change your port setting in putty and save it after changes to your OS files & firewall.


Ok, that's alot to take in but I will check things out today or tomorrow.
