https available although no service is listening on 443 ?
I just created a cloud database service. When SSH into its VM, I find that the ORDS service is running and I can access the default page via https from another system ( after bypassing the warning of invalid certificates ) . I notice that netstat does not show any service that is listening on the port 443 on this VM. I check again with telnet localhost 443 and I do get a connection refused message.
When I run tcpdump on the port 443 and access it again from another system, it does show tcp transactions from the remote host into the VM on this port.
How can this happen when no service is listening on 443 ?
Thanks for your help.
