I have disabled in dnsmasq the : lcprd*.samsungcloudsolution.net
and it is much much better,
this was really crazy, when I went to main menu, immediate request to lcprd2.samsungcloudsolution.net, same for the hub etc.. almost during each operation with the TV was a request to this address, and after disabling it everything is still working fine
now I need to get rid this Netflix crap. seems all the time is running in background and doing always some traffic to *.nettflix.com
If you need some inspiration, here are my current dnsmasq rules:
Code: Select all
address=/.msecnd.net/0.0.0.0 address=/.vo.msecnd.net/0.0.0.0 address=/.samsungotn.net/0.0.0.0 address=/.samsungelectronics.com/0.0.0.0 address=/.akamaitechnologies.com/0.0.0.0 address=/.deploy.akamaitechnologies.com/0.0.0.0 address=/.samsungcloudsolution.net/0.0.0.0 address=/.smartthings.com/0.0.0.0 address=/.samsungrm.net/0.0.0.0 address=/.samsungacr.com/0.0.0.0 address=/.samsungads.com/0.0.0.0 address=/.samsungadhub.com/0.0.0.0 address=/.samsungcloudcdn.com/0.0.0.0 address=/.trafficmanager.net/0.0.0.0 address=/.cloudapp.net/0.0.0.0 address=/.netflix.com/0.0.0.0 address=/.yahoo.com/0.0.0.0
Also intercepting UDP 53 in case these smarty-pants would like to bypass blocking by DNS
intercepting UDP 53 is a very good hint too, I could see rarely from my TV query to google DNS 188.8.131.52:53, strange
When my tv is booting, than it is connecting to this server too...
Yeah I know, it's a NEXT good reason to block ALL communication with *.samsung.com
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on http://ctrlv.it/ Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!
For reference: https://github.com/MultiScreenSDK
You should install Tizen SDK if not done yet, much to play with
more the question was why it is connecting there If you know more details what the TV is doing there....
I have the TV in developer mode, also has Tizen studio with own apps in the TV...
but don't understand why the TV is doing this connection.
but I will disable it and let's see if there is some effect or not, unfortunately cannot disable the whole *samsung.com due to the SDK and forum also.
From several apps in link I given:
replace multiscreen.samsung.com to dgpcnfdr6d6y5.cloudfront.net
dgpcnfdr6d6y5.cloudfront.net are contacted too,
on my TV during boot the : multiscreen.samsung.com is contacted also.
I am not 100% sure but seems the TV is trying to discover the multiscreen/smartview clouds apps on these servers.
multiscreen is called now smartview
I mean the widget tmg file from apps.samsungcloudcdn.com/
