A Network Protocol Analyzer is a tool used to capture and analyze signals and data traffic over a communication channel. It is a tool for troubleshooting, securing, analyzing, and maintaining productive, efficient networking infrastructures. Network protocol analysis is the truth serum of network communications. If you want to find out why a network device is functioning in a certain way, use a protocol analyzer to sniff the traffic and expose the data and protocols that pass along the wire.

Packet slicing simply saves a specific number of bytes from your packets rather than the entire packet. By default, most network protocol analyzers will save the entire packet, but there are many scenarios where you might want to save a portion of the packet instead of the entire packet.

Packet Peeper is a free network protocol analyzer (or ‘packet sniffer’) for Mac OS X. Its features include: TCP stream reassembly; Privilege separation; Simultaneous capture sessions; Filters, which may be defined at any time. Packet Peeper uses the same syntax as tcpdump and Wireshark (or any other program that uses the pcap library).

You can use a network protocol analyzer LAN or WiFi traffic, this even includes password protected communication such as WEP, WPS and WPS2:

• Troubleshoot hard-to-solve problems
• Detect and identify malicious software (malware)
• Gather information, such as baseline traffic patterns and network-utilization metrics
• Generate traffic for penetration testing
• Work with an Intrusion Detection System (IDS) or a honeypot
• Spy and eavesdrop on traffic (e.g., locate unauthorized Instant Messaging—IM—traffic or wireless Access Points—APs)

↓ 01 – Wireshark Windows macOS

Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions.

↓ 02 – tcpdump macOS Linux

tcpdump is a common packet analyzer that runs under the command line. It allows the user to intercept and display TCP/IP and other packets being transmitted or received over a network to which the computer is attached. tcpdump prints the contents of network packets. It can read packets from a network interface card or from a previously created saved packet file. tcpdump can write packets to standard output or a file.

It is also possible to use tcpdump for the specific purpose of intercepting and displaying the communications of another user or computer. A user with the necessary privileges on a system acting as a router or gateway through which unencrypted traffic such as Telnet or HTTP passes can use tcpdump to view login IDs, passwords, the URLs and content of websites being viewed, or any other unencrypted information.

↓ 03 – WinDump (tcpdump) Windows

WinDump is the Windows version of tcpdump, the command line network analyzer for UNIX. WinDump is fully compatible with tcpdump and can be used to watch, diagnose and save to disk network traffic according to various complex rules. It can run under Windows 95, 98, ME, NT, 2000, XP, 2003 and Vista.

WinDump captures using the WinPcap library and drivers, which are freely downloadable from the WinPcap.org website. WinDump supports 802.11b/g wireless capture and troubleshooting through the Riverbed AirPcap adapter.

↓ 04 – Microsoft Message Analyzer Windows

Message Analyzer enables you to capture, display, and analyze protocol messaging traffic; and to trace and assess system events and other messages from Windows components. Message Analyzer enables you to display trace, log, and other message data in numerous data viewer formats, including a default tree grid view and other selectable graphical views that employ grids, charts, and timeline visualizer components which provide high-level data summaries and other statistics.

It also enables you to configure your own custom data viewers. In addition, Message Analyzer is not only an effective tool for troubleshooting network issues, but for testing and verifying protocol implementations as well.

↓ 05 – Ettercap Windows macOS Linux

Ettercap is a comprehensive suite for man in the middle attacks. It features sniffing of live connections, content filtering on the fly and many other interesting tricks. Anime hatsune miku episode 1. It supports active and passive dissection of many protocols and includes many features for network and host analysis.

↓ 06 – Nirsoft SmartSniff Windows

SmartSniff is a network monitoring utility that allows you to capture TCP/IP packets that pass through your network adapter, and view the captured data as sequence of conversations between clients and servers. You can view the TCP/IP conversations in Ascii mode (for text-based protocols, like HTTP, SMTP, POP3 and FTP.) or as hex dump. (for non-text base protocols, like DNS).

In addition to using secure protocols and encrypting information, most business concerns can prevent attacks by using packet sniffer tools software that can detect wireless network sniffers. When you are looking for one such useful software for your business, you can search for them in Google by typing packet sniffer tools Windows, list of packet sniffing tools, HTTP packet sniffer, open source packet sniffer, different packet sniffing tools, network sniffing tools, best-sniffing tools and packet sniffing programs.
