Hi, I'm writing a client and server program for cluster computation. I noticed that nmap sees a specific port as open on Fedora Server and as filtered on Fedora Workstation when the server is running and sees this port as closed on Fedora Server and as filtered on Fedora Workstation when the server is not running.
While looking into the firewalld configuration I found that Fedora Workstation and Fedora Server have one major difference their configuration files: <port protocol="udp" port="1025-65535"/> <port protocol="tcp" port="1025-65535"/> After removing these specific lines from /etc/firewalld/zones/FedoraWorkstation.xml, using firewall-cmd, the ports are still accessible by the client and server program. Can someone please tell me how to close these ports on Fedora Workstation? And why does nmap report the ports as filtered on Fedora Workstation and as open/close on Fedora Server? Best regards, Mischa. _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
