OPMN port conflict


To address this issue, perform the following steps before installing or upgrading:

  • Check if the port 6000 is being used (“netstat -a | grep 6000”)
  • If so, you should disable the graphics console login process on the Linux server. This can be accomplished by logging in as root and issuing the following commands:
    • Find the process that uses port 6000 by the command “lsof -i TCP:6000”.
    • Use “kill -9” to abort the process found in the previous step
    • Confirm that nothing is listening at port 6000 (“netstat -a | grep 6000”)
    • Modify /etc/inittab by changing “id:5:initdefault:” to “id:3:initdefault:”
    • Run “/sbin/init 3” to restart dtlogin
