Viewing Open Services on a Device
- Viktoryia Varapayeva (Deactivated)
The Open Services page (Device Viewer > Device/Network Explorer > Open Services) lists all TCP and UDP ports that are currently open on the device. This feature not only gives you a picture of what the selected device is doing – but it can also give you a quick view of possible security holes in the device’s basic configuration. Based on the device type, NetMRI will expect certain services to be configured on the device, and those values will appear in the Expected Service column as the protocol name. Devices will often show services such as telnet, BootP, or SNMP as a service. Services that are detected as being actively used on the device appear in the Verified Service column.
Should a Listen Address value appear as 0.0.0.0, it indicates that the service is configured to run on all ports on the device.
Many devices that operate as switches or routers will not run any additional services and will show no records on this page.
