FSLS does bind the following ports :
Is there a file where it's defined ? Can I mod this ?
For your information, those ports are being used by Linux Security internally for different purposes as below.
Interface Port Description
lo 28005 Web User Interface internal communication port
lo 28078 PostgreSQL alert database
lo 28080 Local WEb User Interface access
any 28082 Remote SSL Web User Interface access
For more information, you could refer to the following admin guide (Page 11, 'Network Resources').
Basically, those ports are defined in the following files but we do not really recommend you to change them manually because it may cause an unexpected issue with the product functions or etc.
Thank you very much.
