Setting up ports for OS fingerprinting

BMC Atrium Discovery maintains a list of the port numbers that it interrogates. These ports are only scanned if the "Use IP Fingerprinting to Identify OS" option is enabled. See Configuring discovery for more information on this option.

If you want to set up any additional ports, for example if you use a non-standard port number, you need to enter this here.

To set up port settings

  1. You will find the Port Scanning page by navigating to the Discovery Configuration page, contained in the Discovery section of the Administration tab. Next to the Use IP Fingerprinting to Identify OS option you will find the Configure Port Scanning link.
  2. The Port Scaning page is displayed.
    Any currently configured ports are listed.
  3. To change any of the Port values, click Lock for Editing.
    This ensures no other users can access the settings while you are editing.
  4. Edit the port settings:
    • To create a new port value, click Add.
      An additional entry row is displayed at the end of the table.
    • To amend an existing value, click Edit for that entry.
    • To remove an entry, click Delete.
  5. Set up the values as follows:

    Field Name

    Details

    Number

    Port number to be used.

    Name

    Name of application.

    Description

    Free-text description of the application.

    TCP Enabled

    Select this checkbox if TCP uses this port assignment.

    UDP Enabled

    Select this checkbox if UDP uses this port assignment.

    Reason

    Complete this if a non-standard port has been used.

  6. Click OK to save the new or changed details.
  7. Click Apply to remove the lock and allow other users to edit the settings. If you click Cancel at this point, any changes you have made are discarded.
