[SOLVED] Daylight Savings Clock Problems. Internet Time Settings not Working.

Hi xilolee,

I am not sure how the polices were set. I set them to disabled.

After a bit of digging I came to the realization that the problem with the internet time server connection may be with my internet provider (MTS). I stumbled on a thread that said:

"There is a known Security Issue with NTP Inbound that required MTS to block Port 123 Inbound, until it could be patched. The patch is currently rolling out (over the next several weeks), and once that is completed and tested we will be removing the block on the NTP port (123).

This block does not affect Outbound requests, but most devices expect the inbound to also be on port 123, so it will fail unless you can set your device to a different port.

However, MTS has a NTP Clock within the network that is not blocked. If you can set your device to point to ntp.mts.net your device can get the correct time."


If I use the internet time server "ntp.mts.net" my time synchronizes correctly, and all other servers timeout. I sure wish I would have been informed of this beforehand. It would have saved me quite a bit of time.

So my problem is resolved!


 
That port 123 bug was identified in January 2014!!! and should have been patched by your provider long ago! Another recent vulnerability was found in April. I hope your ISP does not take another year to patch that.

The most recent bug with NTP was discovered just in October but involved badguys being able to conduct a DDoS attack using time servers. It would not have affected you directly and the patch was put out almost immediately. It sounds like your ISP's security folks don't really know what they are doing. :( At least they appear to be working with an over-abundance of caution rather that sticking their heads in the sand and pretending these threats are not out there. But really, they need to be applying the patches sooner.

I am glad you discovered it is your ISP and not something going on with your computer before we fixed your computer to death! ;)

BTW, I recommend signing up for the Department of Homeland Security's US-CERT Cyber Security Bulletin Vulnerability Summaries. Through these is how I learned of the NTP problems. I am just sorry I did not put 2 and 2 together and realize it might be your ISP blocking NTP access.
