Colasoft Capsa 11 Free Operation and Options
The operation of this program is very simple, later when we go to analyze all the information that we have available we will have it perfectly organized to find everything we need. In the main menu we will have to choose which physical network interface we can use, we will click on the white box selecting the physical interface. Once selected, we will have to choose which analysis profile we want to take, there are different types of profiles to only collect and display the information that interests us:
- Complete analisis
- DNS traffic analysis
- HTTP traffic
- Email Traffic
- DNS traffic
- FTP traffic analysis
Once we have selected the profile, we will click on the green button that indicates “Start”.
If we go through the different profiles, on the right side it will indicate which modules it has loaded to check all its traffic, logically, if we select “Full Analysis” we will be able to select all the information. Depending on our needs we can choose one profile or another, we have chosen the analysis of “FTP” only, but you can choose the profile you want.
In the main menu we can see the use of the link and the traffic in bytes that we are sending and receiving, in the upper part we can access different options available and even change the Ethernet network card, we can also see the analysis of FTP traffic in a way easy and fast.
In the “Log” section we can see all the DNS-level registration that we have made with our equipment, and also the FTP log if we have made this type of communication.
In the «Summary» section we can see packet exchange statistics, the current ones in real time, the average and other important information.
In the “Protocol” section we can see a classification by protocol of the bytes sent and received, as well as the total of the packets, right at the bottom we can see to which MAC address the different packets go and even their IP address, all this shown in an easy to understand way.
In the “MAC Endpoint” section we can see all the MAC addresses that it has detected on the network when communicating with the different computers, we can see all the communications made by us and those made to us.
The same happens with “IP Endpoint”, instead of showing us the MAC addresses, we can show the related IP addresses and with which we have made communications. Another important detail is that it will show us the country where we have made a specific communication, ideal to know with which countries we are communicating.
In the “IP Conversation” tab we can see the origin and destination of the different packets, showing us the country where that specific IP address is located, in addition, we can see the duration, the bytes sent and received and much more information, and everything it very easy to understand.
In the “TCP Conversation” section we will see all the TCP communications that we have made, with their corresponding origin and destination, duration, bytes sent and received and more information.
In the “UDP Conversation” section we will see all the UDP communications that we have made, mainly the traffic made by UDP is the DNS traffic.
We can also see the different ports of origin and destination.
Next, in the «Matrix» section we can see a graph of all the traffic carried out.
Finally, in the section on the left, we can filter by different protocols, IP and MAC, in order to search for the FTP connections made.
As you have seen, this software is very easy to use and understand, it will allow us to monitor all our equipment with outgoing and incoming connections easily and quickly. For example, the Wireshark program with its corresponding filters would provide us with the same information, but with this program we will have everything classified so that we do not have to use these advanced filters that Wireshark has.
