  • Counter: [Number of checks you want do].

To check any conexion to one specific port, we will configure the settings as follows:

This option shows a list of all open ports on a host.

• Timeout: [The allowed maximal time for a process to end normally].

To capture traffic that pass in CommsMundi on all network interfaces or only a specific one, it can be done using the tool locate in the page “Networking → Diagnostic page” in the tab “Packets capture”. Using this tool allows you to download a .pcap file containing the resulting capture, so you can later on open with a network protocol analyzer program, for example wireshark.

The steps to perform a capture are:

1. Timeout: 30 seconds
2. Size: 20
3. click: start to begin the diagnostic
4. after the diagnostic stop you can download the resulting file from the table files by clicking on the name of the files.
