PRTG Manual: Port Scanner Tool
The port scanner tool provides the ability to scan specific ports on multiple devices in one simple interface.
Launching the Port Scanner tool
The port scanner tool can be launched from the 'Tools' tab on the main view of UVexplorer. It can also be launched from the device context menu available on the device grid and the topology map.
Using the Port Scanner tool
To scan ports with the port scanner tool you need to select the ports and devices to scan, choose the protocol and then select the scan button.
To select ports use the check list combo box available at the top of the control. The combo box contains a list of common ports with their port numbers and descriptions. To select the ports expand the list and select the checkbox next to the ports you would like to include in the scan.
Each service running on a port can choose to use either TCP or UDP as the communication protocol. In order to scan the ports you must choose which protocol to use while scanning.
The port scanner tool is populated with all of the devices in the discovery result. To scan the selected ports on a device the check box in the device list must be selected.
Once the ports, protocol, and devices are selected you press the scan button to begin the scan. The port scanner tool attempts to connect to each port using the selected protocol. If the connection is successful the port is considered open
When the scan is completed the result of the scan for each device and port is listed in the results view. When wanting to perform additional scans the results of the previous scan can be cleared using the clear button.
The 'Name' column contains the display name of the scanned device.
The 'IP Address' column contains the primary IP address of the scanned device.
The 'Port Name' column contains a description of the common known service run on the provided port.
The 'Port Number' column contains the number of the scanned port.
The 'Port Status' column contains the status of scan results. The port is either OPEN or CLOSED. If the scanner is able to connect to the device port with the selected protocol the port is considered open.
