Host : Traffic grouped to one file per host. unidirectional traffic for a 5-tuple, is grouped Possible values for are:īssid : Traffic grouped based on WLAN BSSIDįlow : Each flow, i.e. s : Split traffic and group packets to pcap files based on. Larger buffers will speed up the process due to fewer disk write operations, but will occupy more memory. b : Set the number of bytes to buffer for each session/output file (default = 10000). More sessions might be needed to split pcap files from busy links such as an Internet backbone link, this will however require more memory p : Set the number of parallel sessions to keep in memory (default = 10000). In each class, except Class D, there is a range of private IP addresses. IPv4 addresses have four classes, Class A, Class B, Class C and Class D. Public IP addresses are used when communicating on the Internet, while private IP addresses are used by devices to communicate within a private network (Chandra, Kathing and Kumar, 2013).

IP address 140.247.62.34 is not helpful as it is a public IP while Nitroba’s intranet had private IP addresses (Ring, Dallmann, Landes and Hotho, 2017). Further, to analyse the IP address packets to see if more evidence gets more essential clues. Figure 25 Filter rule I used to narrow down to traffic belonging to IP 140.247.62.34 If the filter were wrong, it would be highlighted with the colour red and not green, as the case might be. We apply a filter that captures all traffic incoming and outgoing from the IP address captured from the email headers sent by Tuckrige 140.247.62.34 / 192.168.15.4. The hashes calculated by Wireshark and those provided along with the nitroba.pcap file is similar, representing that the file we have has not been altered. This was particularly useful and technically needed to advance knowledge because so many packets need to be analysed, although they are time-consuming.

To group information according to similarity, filters need to be used.

One can only view one packet and its metadata at a time.
