Is there a way to have my UnRaid Server be a NTP server for all my local IoT devices and cameras? I've tried to make a customer docker with some Chrony Dockers on Github but when I start it all I get is a cmd prompt. 

 

Unraid has a built in NTP server by default. Just point your devices at Unraid's IP.

Hi @JonathanM can you please specify?

I have a security cam that has the possibility to setup a custm NTP server but it asks me Server adress and port. I tried to change adress to my unraid server local address and let default port (123) but it doesn't work.

 

Any hint?

TY

Can you verify that the server and camera are on the same subnet with no firewall rules that would restrict traffic? I just verified again and it "just works" for me.

yes Cam has a rule that should be restrict to lan only. But both camera and server are in the same subnet: 192.168.2.xxx

If you have a windows machine on the same subnet, open a command prompt and

net time \\<serverIP> /set /yes

If it returns with "Current time at \\<serverIP> is <DATE> <TIME>

The command completed successfully."

Then the ntp service on the server is responding.

Hey @JonathanM is this still the case? I just tested it with my Mac client in the same subnet, but got a timeout. Anything else to be aware of?

Hi @JonathanM my camera is in different VLAN from the unraid server. How can I use unraid IP to point as NTP on my camera settings?

Add a firewall rule to pass port 123 UDP?

Where should I set this? On unraid? If yes, how can I set it? Are there any commands please?

On your firewall where you have the VLAN routing set up? I'm probably not the best person to ask, I don't have much experience with VLANs.

What are you using to setup your networking? VLANs, subnets - a firewall, or a router with firewall perhaps

@JonathanM @apandey The VLANs are setup on TP link smart switch and I already check the settings on it but there were no firewall settings there. In unraid, I already setup VLAN. Actually I followed this guide by spaceinavder One on YT.

That seems like a layer 2 only switch, so while it will allow VLANs, it won't be able to route through them

What are you using as a router? That's where you need to allow routing between the networks

I'm just using my ISP modem-router. I have no 3rd party router.

Do you have access to that routers interface? You have to route between VLANs if the router or switch allows it, else the default behaviour is to keep them separate

 

Routing across VLANs need one of the following:

1. A layer 3 switch

2. Router with one physical interface per VLAN

3. Router with VLAN trunking enabled

 

You may be out of luck. Inter-VLAN routing is an advanced topics because VLAN traffic is tagged at layer 2 while routing happens at layer 3. Connecting these two is why you need a device which can see separate vlan interfaces in some way (physical or logical). Your switch does not deal with layer 3 at all, your router may not see VLAN interfaces at all

@JonathanMI'm trying to do the same as Jokerigno--set my network cameras (restricted to LAN only) to use Unraid's NTP server. I tested the command you provided in Windows, but got this result:

C:\Users\[username]>net time \\10.0.0.100 /set /yes
Current time at \\10.0.0.100 is 7/25/2023 21:33:49

System error 1314 has occurred.

A required privilege is not held by the client.

I don't see settings in either Unraid or the camera for authentication or privileges.

Edit: This is because I wasn't using an elevated command prompt... when I run this with an elevated command prompt, the time is set successfully.

 

Any ideas why my camera can't set itself from my server? They're both on the same subnet and I'm not aware of firewall rules that would block the connection. The camera already provides video to the server.

Right click the command prompt icon and run as administrator

Did you end up figuring this out? I have the same issue, although across VLAN's, but cannot make it work - tried both the servers domain name and IP Address.
