IPv6 port on Oracle DB server

in Database Administration (MOSC) 2 commentsAnswered

Our IT Security has scanned our Oracle DB servers which 2 nodes are running 19c. They have found that the tcp port 1830 is opened for listening. I have run the command to see if what is it used. The result as:

COMMAND  PID  USER  FD  TYPE   DEVICE SIZE/OFF NODE NAME

java  30640 orarom  77u IPv6 2072491746   0t0 TCP *:1830 (LISTEN)

java  30640 orarom 156u IPv6 2072562882   0t0 UDP *:1830

It's type is IPv6. I have seen the network interface setting that IPv6 isn't enabled. Then I run another command to lookup the system and seen IPv6 is enabled on the Linux OS.

]# /sbin/ip -6 addr

Howdy, Stranger!
