I'm getting emails several times a day with this in the subject line:

Cron <[email protected]> /usr/bin/kcarectl --auto-update --gradual-rollout=auto

The content of the email is this:

The IP XXX.XXX.XX.XXX was already used for trialing on 2018-05-15

I don't remember opting for a trail. How can I resolve this message?

Bill

Hi Lauren -

I will run the command later today and report back. Just to clarify... I started getting this message after installing the KernelCare symlink protection. I am not a customer of the KernelCare kernel patching service.

That sounds good!

I'm not either and I'm getting a similar error on one of my test servers and I'd like to see if the same issue is present on your server:

Code:
# kcarectl --license-info
Your trial license for the IP <MyIPAddress> expired on 2018-05-29
Code:
kcarectl --update
Downloading updates
The IP <MyIPAddress> was already used for trialing on 2018-05-14
Code:
# uname -r
3.10.0-862.6.3.el7.centos.plus.x86_64

HI @BillyS

I've ran our issue by the CloudLinux team and found that there is an issue with the kernelcare patch requesting a license. Right now the only way to stop it is by removing the IP from the CLN. I don't believe this is an optimal solution though as on my personal server when this is done I get the following:

Code:
# kcarectl --license-info
The IP <MyIPAddress> hasn't been licensed
Code:
# kcarectl --patch-info
No patches applied, but some are available, run 'kcarectl --update'.
Code:
# kcarectl --update
Downloading updates
Requesting trial license for <MyIPAddress>, please wait...
HTTP Error 403: Forbidden, Retrying in 3 seconds...
Requesting trial license for <MyIPAddress>, please wait...
HTTP Error 403: Forbidden, Retrying in 6 seconds...
HTTP Error 404: Not Found, Retrying in 12 seconds...
HTTP Error 404: Not Found
I can definitely get your IP removed from the CLN if you don't mind sending me a PM with your IP address (please don't include it in the thread response) Alternatively you can open a ticket using the link in my signature. Once open please reply with the Ticket ID here so that we can update this thread with the resolution once the ticket is resolved.

I have opened an internal case for our tracking purposes but I've also obtained their internal case number KCARE-1036 - as soon as I have information on when this will be resolved I'll update you here.


Thanks!

Hi @cPanelLauren
Code:
kcarectl --license-info
Your trial license for the IP XXX.XXX.XX.XXX expired on 2018-05-30
 uname -r
3.10.0-862.6.3.el7.x86_64
kcarectl --update
Downloading updates
The IP XXX.XXX.XX.XXX was already used for trialing on 2018-05-15
While I'm interested in a long term fix, I'm a patient person and would rather not be removed from the CLN. So I'll check back here for updates :)

As I said I can definitely have your IP removed from the CLN, just be aware it may try and re-request the trial license. If you want me to do this send me a private message with your IP address or open a ticket using the instructions I provided earlier.

I do see they've escalated the priority of the case overnight and I do believe they're going to get a fix out pretty quickly.

Thanks!

Hi @BillyS

Yes, in most cases when KernelCare begins to support the kernel you're running the issue will be resolved. There is just some time in between when the kernel is released to when KernelCare begins supporting it - this is true with both symlink protection and KernelCare's full product.

The issue with this being that when a new kernel is released if you update to it prior to KernelCare's support of it you'll receive the same messages/errors.

Thanks!

Hi @cPanelLauren - So in my System Update setting, I had Include kernel packages selected and I had to reboot the other day. I'm now getting "The IP XXX.XXX.XX.XXX was already used for trialing on 2018-05-15" messages again and Security Advisor shows the system exposed to symlink attacks. Does that mean we should turn off this System Update setting (uncheck include kernel packages)? It makes sense to me now, but I don't see any reference to this setting in cPanel's documentation.

That's really up to you and your preferences. If you uninclude kernel packages you'll need to keep track of updates and manually update when KernelCare begins supporting that kernel version. If this is something you are able to keep track of then it might work for you.

Thanks!
