Lab: Packet filtering, static routes and time synchronization [HELP]


Please check questions 13 and 14 in the link attached as they may contain errors. I have also attached the relevant screenshots for your convenience. Thank you.

Q13: chronyd cannot start, although it’s enabled. systemctl status chronyd.service and journal -xe both have outputs like: "permission denied’’, even though sudo is used upon starting the process. Also, NTP cannot be set to ‘true’ even with sudo.

Q14: I guess RTC cannot be set due to the above issue?

Hi @meletiop

I’ve just been right through the lab and it is all working fine. Did you install chrony correctly?

sudo yum install chrony -y

Last question may not work if you did not successfully complete 13.

Note that some questions may rely on successful completion of earlier questions


I am still facing the exact same issues. The service is properly installed (chronyd), but cannot start. The same is true for NTP.

As mentioned on the other thread, I’m getting it confirmed that Udemy course and KK course use the same version of the lab.
