Trafcalc software uses packet capturing to determine the TCP-payload size of a system, helping to assess traffic and network performance.
I recently tried out interfaceTrafcalc and found it to be a useful tool for calculating the size of the TCP-payload on a system. Unlike other software that operates at the IP level, interfaceTrafcalc works at the user level via packet capturing and connection tracking.
The program uses a pcap callback function, which is called for every incoming (TCP) packet. To manage connections, the program has a database in the form of a global linked list of structs. It adds new connections to the list and removes old ones.
If the program doesn't find a connection in its database, it looks up the user ID for that connection and adds it to the list. It then gets the size of the packet and adds it to the value of the traffic for that user ID. This information is stored in a similar linked list of user IDs.
At a given interval, interfaceTrafcalc writes out all the information to a file in /var/log/traffic. I found this feature to be particularly useful for monitoring network traffic and analyzing usage patterns.
Overall, I would highly recommend interfaceTrafcalc to anyone in need of a reliable and efficient tool for calculating TCP-payload sizes on their system. Its user-level approach and advanced features make it a standout option in the software market.
