How to use the command ipaggcreate (with examples)
The ipaggcreate command is used to produce aggregate statistics of TCP/IP dumps. It can analyze pcap files or network interfaces and provide various types of information such as packet counts, IP packet length, and byte counts between source and destination address pairs.
Use case 1: Count the number of packets sent from each source address appearing in a pcap file
Code:
ipaggcreate --src path/to/file.pcap
Motivation: This use case is useful when you want to analyze network traffic in a pcap file and determine the number of packets sent by each source address. By counting the packets sent from different source addresses, you can identify any potential anomalies or sources of high traffic.
Explanation:
--src: Specifies the pcap file to be analyzed.
Example output:
94.14.23.45: 1203 packets
192.168.0.1: 985 packets
10.0.0.2: 542 packets
Use case 2: Group and count packets read from a network interface by IP packet length
Code:
ipaggcreate --interface eth0 --length
Motivation: This use case is helpful when you want to study the distribution of packet lengths on a specific network interface. By grouping and counting packets based on their IP packet length, you can gain insights into the network traffic patterns and identify any unusual or abnormal packet sizes.
Explanation:
--interface eth0: Specifies the network interface to be analyzed.--length: Groups and counts packets by their IP packet length.
Example output:
128 bytes: 203 packets
256 bytes: 502 packets
512 bytes: 687 packets
Use case 3: Count the number of bytes sent between each address pair appearing in a pcap file
Code:
ipaggcreate --address-pairs --bytes path/to/file.pcap
Motivation: This use case is useful when you want to analyze the amount of data transferred between different address pairs in a pcap file. By counting the bytes sent between each address pair, you can identify the most active communication pairs and assess the overall data transfer activity.
Explanation:
--address-pairs: Counts the number of bytes sent between each address pair.--bytes: Specifies that the count should be in bytes.
Example output:
192.168.0.1 -> 10.0.0.2: 105634 bytes
10.0.0.2 -> 192.168.0.1: 91856 bytes
94.14.23.45 -> 10.0.0.2: 76235 bytes
Conclusion:
The ipaggcreate command provides a powerful way to analyze TCP/IP dumps. With its various options, it allows you to examine network traffic patterns, identify anomalies, and gain insights into data transfers. Whether you are analyzing pcap files or monitoring network interfaces, ipaggcreate can help you make sense of network traffic data.
