Christopher Tenter resolved IGNITE-18781.
-----------------------------------------
Resolution: Works for Me
Thanks, I switched the setup to a different network and it runs fine so far. So
I close the ticket
> Strange ports used - Failed to process selector key
> ---------------------------------------------------
>
> Key: IGNITE-18781
> URL: https://issues.apache.org/jira/browse/IGNITE-18781
> Project: Ignite
> Issue Type: Bug
> Components: networking
> Affects Versions: 2.14
> Reporter: Christopher Tenter
> Priority: Major
> Attachments: ignitelog.txt
>
>
> A two-node cluster occasionally cannot communicate when ignite uses a strange
> local or remote port. We've opened all ports that are documented here
> [https://ignite.apache.org/docs/latest/clustering/network-configuration]
>
> However, ignite uses a seemingly random port for connecting to the other node
> sometimes. By default all ports are closed in the firewall, so the connection
> fails with message "Failed to process selector key"
>
> Here are some connections that ignite attempts:
> locAddr=/10.125.100.93:20395, rmtAddr=/10.125.100.179:47100
> locAddr=/10.125.100.93:10800, rmtAddr=/10.125.100.93:1851
> locAddr=/10.125.100.93:10800, rmtAddr=/10.125.100.93:1775
> locAddr=/10.125.100.93:1323, rmtAddr=/10.125.100.179:47100
>
> So ports 20395, 1851, 1775, 1323 are used, but they are closed in the
> firewall. The ports change all the time. If I add them to the firewall, it
> doesn't take long until another unknown one pops up. I could not find them
> anywhere in the ignite documentation. Where do they come from and how to fix
> it?
>
> The network settings in the server config looks like this:
> <property name="discoverySpi">
> <bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
> <property name="ipFinder">
