As per task below I have performed the below steps:
Task:
" The Nautilus system admins team recently deployed a web UI application for their backup utility running on the Nautilus backup server in Stratos Datacenter . The application is running on port 8083 . They have firewalld installed on that server. The requirements that have come up include the following:
Open all incoming connection on 8083/tcp port. Zone should be public ."
=======================================
STEP 1:
ssh clint@stbkp01
STEP:2
sudo firewall-cmd --permanent --zone=public --add-port=8083/tcp
==============================================
Though I got success response but still the task has been failed. Refer the screenshot.
