I work in the NOC at an ISP in North Central Iowa. For the last 3 weeks or so, we’ve had a rash of reports of a few different models of Samsung “BD-J” bluray players that pop up with “system time updating.” I have wiresharked with a dynamic IP on a TP-Link router, and then gave the Bluray a static IP straight off our Fiber ONT (No router).
Both wiresharks show the bluray querying “pool.ntp.org.” I’m still kind of learning about all of this. Would that mean that Samsung has that default URL hardcoded into these machines? Thats my guess since it appears the same with/without the tplink, just a change on the source IP.
In any case, if they were using the default, could that cause this problem? I guess I’m not totally sure what kind of problems using “pool.ntp.org” would result in…
Any help is appreciated, as this is effecting many of our customers.
