[SOLVED] NTP server on LXC

[nywst]

Which Linux LXC can be configured to be NTP server?
I tried Fedora 39 LXC, seems it doesn't have NTP package.

Thanks.

[root@DNS-test ~]# cat /etc/redhat-release
Fedora release 39 (Thirty Nine)
[root@DNS-test ~]# dnf install ntp
Last metadata expiration check: 1:10:32 ago on Sat Jul  6 03:52:33 2024.
No match for argument: ntp
Error: Unable to find a match: ntp

Any Debian, Ubuntu or SuSE (and derivatives) should be able to function as an NTP server. Even "firewall" distros like ipfire, pfsense and opnsense offer this as a feature.

However, a simple web search came up with this:

You could just use the PVE host for that. I know you should really use an LXC or a VM for any services you wish to add - but this one requires NO installation as basically it already exists inside the Debian-based PVE host.

To do that (my tried setup - from notes) just do the following:

NTP Time Server:

nano /etc/chrony/chrony.conf


# Added by ME for NTP Server
local stratum 8
manual
allow 192.168.1.0/24   # The network you wish to allow to access the NTP time server - change accordingly

# Save & Exit

systemctl restart chronyd

Did not work

apt install chrony
nano /etc/chrony/chrony.conf
# put in as appropriate for my network

# systemctl enable --now chronyd

Even the following did not work in Bookworm:

This seemed better but still did not work:

apt install ntp -y
systemctl restart ntp
ntpq -p

 

[apmuthu]

Even this did not work

apt install systemd-timesyncd -y
systemctl start systemd-timesyncd
systemctl status systemd-timesyncd

I installed chrony to get it done quickly; thanks.

btw, Ubuntu LXC is better than Fedora.
