RE: Question regarding Oracle listener port change

I’m just curious.  

Doesn’t everyone with a public network wan change the 1521 port and put a honey pot on 1521 to absorb attack vectors?  

Do folks actually leave it as 1521 for systems that allow off-closed-campus access?

Hi All,  

Just to keep you all updated, the reason for port 1521 working was , we had teleran software installed which was internally swapping the port from 1521 to 1621. Below is the snippet from teleran logs.      

managettds.log:03/23/2019 20:05:19:589 TT03235 <INFO> (genericdb) Connecting to Knowledge Base: jdbc:oracle:thin:_at_//xxxxx-scan:1521/<SID>

managettds.log:03/23/2019 20:05:29:312 TT00712 <INFO> (ttsystem) Swapping Oracle port from 1521 to 1621

Did you change the ports on both the scan and the local listener? Update the database parameters and re-register?

I also tried connecting to the database using scan and default service using 1621 port as well. With that also I am able to connect. Should I ideally get my connection request with port 1521 rejected with some TNS errors?? Or is this is expected??
