Configure Port Scan Settings
The IDF Server Plug-in can be instructed to scan a Computer for open ports by right-clicking the Computer
and selecting Actions > Scan Computer for Open ports, or by clicking the Scan for Open Ports
button on the Firewall screen of the Computer's Details window (where the results of the latest scan are
displayed).
(Port scans can also be initiated by right-clicking an existing Computer on the Computers screen and
choosing "Scan Computer for Open Ports". Another way to initiate port scans is to create a Scheduled
Task to regularly carry out port scans on a list of Computers.)
By default, the range of ports that are scanned is the range known as the "Common Ports", 1-1024, but
you can define a different set of ports to scan.
Port 4118 is always scanned regardless of port range settings. It is the port on the Computer to which
Server Plug-in initiated communications are sent. If communication direction is set to "Client Plug-in
Initiated" for a Computer (System > System Settings > Computers), port 4118 is closed.
To define a new port range to be scanned:
1. Go to Components > Port Lists and click New in the menu bar. The New Port List screen will
appear.
2. Type a name and description for the new port list and then define the ports in the Port(s) text
box using the accepted formats. (For example, to scan ports 100, 105, and 110 through 120, you
would type "100" on the first line "105" on the second, and "110-120" on the third.) Click OK.
3. Now go to System > System Settings > Scan and click the "Ports to Scan" drop-down menu.
Your newly defined Port List will be one of the choices.
