trial license expired

[ksko]

hello, guys.

I think there's a period left, but "Player" demo app failed to start

Until when can I use it?

That's the problem.
First, please restart WCS. If this does not help, check if pool.ntp.org is permanently available from server.

 

[ksko]

It's normal after a restart.
I'm using rdate instead of ntpd, should I set up ntpd?

WCS uses Java NTP client implementation trying to sync time in system independent way. So there are no requirements to system NTP client, but pool.ntp.org should be permanently available from server.

It is not being published with the message ""License period is expired Mon May 10 18:19:46 KST 2021 Wed Jun 02 00:00:00 KST 2021 Wed Jan 01 00:00:00 KST 3000"

The connection to the ntp server is good as shown below.

Restarting servers due to licensing issues is a big problem for our services.
What should I do?

I was testing normally and suddenly it's not working.

Make sure server date time fits NTP date time.

sudo apt-get install ntp
sudo service ntp start

Even though you said I don't need it, but I already installed it.

I am using CentOS7, and already installed ntpd.

Restarting servers due to licensing issues is a big problem for our services.
What should I do?

With trial license, you have to restart WCS in this case.
For production use, you should buy a mohthly subscription license, it requires permanent access (every 15 minutes) to license server. If this is not available for some reason, license will drop to expired state until license server becomes availabel again. In this case, no server restart is needed.

 

[ksko]

OK, There is no license error on AWS EC2 instances yet.

I want to check again,
is it right that we don't need to install ntp or ntpd?
If the license server fails, is it correct that we cannot provide the service until it is recovered?

 

[Max]

Yes.

If the license server fails, is it correct that we cannot provide the service until it is recovered?

The license server itself is fault-tolerant. If connection to license server fails while license checking, new streams cannot be published and played, but existing publications and subscribers remain. If next connection (after 15 minutes) to license server is successful, new streams can be published and played again without WCS restart.
