tcpdump features and specs

• Powerful packet capturing
  tcpdump offers comprehensive capabilities for capturing network packets, providing detailed insights into network traffic, which makes it a powerful tool for network diagnostics and analysis.
• Wide compatibility
  Being a widely used tool, tcpdump is compatible with numerous operating systems, including Linux, Unix, and macOS, ensuring accessibility across different platforms.
• Filter flexibility
  tcpdump supports a wide range of filtering options that allow users to capture specific types of traffic, ensuring efficient and targeted packet capture.
• Command-line interface
  tcpdump is a command-line tool, which provides advanced users the ability to script and automate tasks, making it highly efficient for those familiar with command-line operations.
• Free and open-source
  tcpdump is open-source software, which means it is freely available for use and can be modified and distributed by anyone, fostering a community of users and contributors.

Possible disadvantages of tcpdump

• Steep learning curve
  For users unfamiliar with command-line interfaces and packet-level networking, tcpdump can be difficult to learn due to its complex commands and options.
• Minimal graphical interface
  tcpdump lacks a graphical user interface (GUI), which can make it less accessible for users who prefer visual tools over text-based interfaces.
• Limited analysis capability
  While tcpdump is excellent for capturing packets, it offers limited built-in analysis features, requiring additional tools for comprehensive analysis of captured data.
• High resource usage
  Running tcpdump with extensive capture options or on high-traffic networks can result in significant CPU and memory usage, potentially impacting system performance.
• Security risks
  tcpdump requires root or elevated privileges to capture packets, which could pose security risks if not managed correctly, especially on sensitive systems.
