Many connections

Clean install on a Vero 4K+
I have issues with streaming iptv, lots of buffering. I have fiber to the home, my provider is Ilox, in Mexico, my DL is 38+, up is 23+, latency 54.
In order to troubleshoot I installed YAmon on a dd-wrt router, this gives the ability to see, in real time, connections to the internet.
In looking over the reports, I noticed some connections from the Vero, to questionable locations, all on port 123, ntp. Thinking there maybe some form of exploit on the Vero, I elected to flash a new image, the latest, 20200607.img.gz.
Monitoring the yamon report page, I see many connections, made by the vero to, some websites:

Private Network 53 124

Vero Front Bedroom 123 Interoute Communications Limited 123 76

Again, this is a clean, fresh install, as of today, June 25, 2020
Pointers appreciated

I would guess that you have open ports on your router. Check the routers configuration.

a shutdown of the vero results in the above connections, goes away. No connections to the listed addresses.
A direct question, maybe Sam will chime in.
Why are these connections to some foreign server, unrequested, unwanted, no addons installed,on a fresh install of OSMC occuring? The md5sum checks as correct, what else is to be suspect, other than some nefarious action. Do you recognize the IP’s? Is this something that you condone, and allow? Rather than speculate as to what MAYBE the issue, answer the above questions, or not. Of course the router has an open port, how else would you expect to receive the correct time.

What makes you think that they are not valid NTP servers?

I mean open ports to your network. Like port 22 (SSH) being open.

so, is this really necesary? on a fresh install?

You haven’t asnswered the question. Why do you think that they are not valid NTP servers?

According to pool.ntp.org: NTP Servers in North America, north-america.pool.ntp.org, there are 648 active servers for the North America region

well, how many time servers are needed, to correct the time? Do I REALLY need 648 time servers?
Instead of DUCKING my original, valid question, answer it.
Are THESE legitimate servers, authorized by OSMC, and REQUIRED to function.

so, this is a TIME sever, interesting

I don’t think anyone is ducking questions.

What makes these connections questionable?

If they’re on Port 123 - they will be NTP outbound connections. I’m assuming you haven’t port forwarded SSH and your system isn’t compromised.

You can disable NTP and rely on HTTP time instead, which is set once per boot, but this will drift and as NTP will no longer be running, this will could drift out significantly unless you reboot periodically.

You could also reconfigure NTP to use a trusted server of your choice.

A number of time servers are used to prevent single servers from becoming overloaded and facilitate redundancy. Even with our user base, if we pushed 1.5 million users over to a single NTP server, we could cause problems for someone else’s infrastructure.

do a search on ntp exploits
As stated in my original post, there is buffering, for NO apparent reason, other than ISP created issues, data caps, or throttling.
Would you not question, seeing unrequested, unwanted connections, on a fresh install, to some foreign address?
Come on.

NTP exploits typically occur on the client side due to a bug in the daemon, but we deliver security updates and our distributed version of ntpd does not have any known, active exploits. The NTP pools we use are trusted and used by millions of users. They are used by Debian and Ubuntu users.

Any OS is going to have outbound traffic, even on a fresh installation.

The amount of bandwidth that NTP will use is extremely minimal. It would not be responsible for buffering.

You may wish to disable NTP or change the servers used to ones that are less ‘foreign’ or ones that you trust particularly. You could also just block outbound traffic on port 123 on your router, but this could have consequences for other devices that do not have a fallback mechanism for resolving time, such as some CCTV cameras.

so, Sam, your saying ALL of the IP addresses, that I have submitted, are related to NTP time config?
Do I have that correct?

Unless you have port forwarded your device or made any changes to the system, all Port 123 traffic will be to NTP servers.

As you haven’t uploaded any logs, it’s not possible for us to check if you have made any changes or look for obvious signs of intrusion.

well, at this point in time, I choose to NOT allow ANY VERO product to connect to MY net work, you have failed to adequately address the issues I have raised, that are, in my mind valid and reasonable.
Why, for example, must there be a connection to a General Motors website, do they provide a time service? What service is provided, that OSMC relies on? What other data is harvested?
You have not explained any connection to ANY of the IP addresses.

The IP addresses you have posted are NTP time servers. They are not websites.

You can disable the NTP time service completely if you wish to do so and I can provide instructions.

Alternatively, I can provide instructions for how to use an NTP server of your choosing. I don’t know if your ISP provide one specifically. You could use mx.pool.ntp.org - but this involves a pool of servers so there would be multiple IP addresses.

No personal data is collected, because no such data is sent. Your system is simply asking for the time and getting a response.

Hopefully this clarifies the use of those IP addresses and why you see traffic to them as well as your options. You can learn more about NTP with the summary here: Network Time Protocol - Wikipedia

Of the large list you posted above, only two do not respond. (NTP servers can be anywhere and are often provided by individual volunteers. There is no guarantee that an NTP server will be online, which is why there are so many.)

So your list of addresses actually demonstrates that all but two are valid NTP servers. The other two could be offline for many reasons.
