Re: configuration for comment bitswarm.sessions.DefaultSessionManager logs

Can you please provide more details? Where is SFS2X installed, on your local machine? When do these connections appear? As soon as the server is started? The addresses shown in the logs are from the local network, so it seems that other machines in a local network are attempting to connect to your s...

Re: Setting up SFS2X with ec2 instance using Amazon Linux

Try telnetting the server on the http port.
Example:

Code: Select all

telnet <ip-address> 8080

Do you get a connection?
(Similarly you can do the same with port 9933, to check if it's open)

Thanks

Re: configuration for comment bitswarm.sessions.DefaultSessionManager logs

Hi,
these are some very short-lived connections that seem to be coming from a local network.
As to why, I can't say without more details.

Thanks

Re: Setting up SFS2X with ec2 instance using Amazon Linux

Hi,
when using AWS you need to configure the so called "Security Group" which is their fancy name for a firewall :)
Check the Security Group associated with your EC2 instance and add a few inbound rules to allow traffic for the ports you've listed above.

That should fix it.
Cheers

Re: Managing Reconnections and Handling: User Already Logged In

Unfortunately it's still not clear what you're trying to do. I get that you'd like to check whether or not a client is in the middle of a connection, but this should be obvious in your code without the need for extra API calls. A connection attempt starts when you invoke the connect() method and it ...

Re: JavaScript extension support in future versions

Hi,
GraalVM JS is an option we're looking into. It supports all the recent specs of the Javascript language and it seems to have a somewhat better support for multi-threaded environments than Nashorn.

Re: Slow connection to rooms

The discussion about threads is not very relevant to your issue but I brought it up just to clarify that each instance of the client API (used for the stress test) already creates the required threads for connection internally. This means that using an external thread pool is redundant. If you want ...

Re: Managing Reconnections and Handling: User Already Logged In

I recommend double checking that there is no User connected before testing. You can do that via the AdminTool > Zone Monitor and selecting the Zone you're using. There you can find the Users already logged in. Next you can test again with your client: if the same error is triggered, check again with...

Re: Slow connection to rooms

Side question : why do you need to create a 1000 threads on the client side? If you're using the SFS client API they already create the necessary threads internally. All you need to do is running a for loop that generates every client and starts the connection, followed by a brief Thread.sleep() in...

Re: Slow connection to rooms

If CPU is 100% loaded you're pushing the hardware to its limits, which explains the latency. However I would expect that a 1000 CCU doing a connection + login + join Room would pose very little problem for a 4-core machine, even in the cloud. In fact we have run dozens of tests on AWS tiny servers, ...

Re: Managing Reconnections and Handling: User Already Logged In

Ok, so it is Websocket, which does not support automatic reconnections. However the second part of my previous response still stands, it looks like the disconnection was not acknowledged by the server side. Only an internal timeout will complete the disconnection. This can be the server's own "...

Re: Slow connection to rooms

Hi, it depends on the conditions of the test. Are server and clients on the same machines or separate? What are the hardware specs of the server? Did you check what is the CPU usage during the test? Also when you're saying that 1000 clients are connecting "at the same time" I hope you did ...
