RHEL / Centos / Oracle Linux firewall configuration was created by emmanuel_chrisment
I'm trying to setup a runtime on a machine running on Oracle Linux 8.4. The runtime itself runs very well. But I'm unable to connect to it through another machine. I've opened those ports on the firewall of this Oracle Linux machine :

public (active)
ports: 42000/tcp 42100/tcp 42101/tcp

This doesn't seem to be enough, since I get this message when trying to connect to it :

Connection refused to host: sclf-stambia-rt3; nested exception is:
java.net.ConnectException: Connection refused: connect

Does anybody had success on configuring the firewall ? I would like to keep it active as much as possible.

Thanks in advance for your advices.

Please close this topic. Opening the ports listed in my post was enough. The problem was that because of security configuration on Java, the runtime wasn't able to connect the the MS SQL log database. Once this was fixed, connection to the runtime was possible.
