Wireshark: The Ultimate Network Protocol Analyzer for Linux Single Machine

Wireshark, one of the most powerful network protocol analyzers available today, has become an essential tool for network administrators and security professionals. This article will focus on installing and using Wireshark on a Linux single machine.

### Time Display Formats and Time References

Before we dive into the installation process, let's take a look at some basic concepts in Wireshark. The 'Time Display Formats' dialog box allows you to customize how time is displayed in your capture files. You can choose from various formats such as UTC (Coordinated Universal Time), local time, or even specify a custom format.

### The 'Go to Corresponding Packet' Command

The 'Go to Corresponding Packet' command is one of the most useful features in Wireshark. This command allows you to navigate through your capture file and jump to a specific packet based on various criteria such as timestamp, protocol, or even a specific byte pattern.

### Building Display Filter Expressions

Display filter expressions are used to filter packets in your capture file based on various criteria such as protocol, port number, or even specific bytes. Wireshark provides an extensive set of display filters that can be combined using logical operators to create complex filter expressions.

### Some Protocol Names Can Be Ambiguous

Wireshark supports a wide range of network protocols and each protocol has its own set of packet structures and fields. However, some protocol names can be ambiguous, which can make it difficult to identify the correct protocol. This is where Wireshark's 'Protocol Hierarchy' feature comes into play.

### Pop-up Menu Of The “Packet Diagram” Pane

The 'Packet Diagram' pane provides a graphical representation of your capture file and allows you to visualize the packet structure. You can use this pane to navigate through your capture file, inspect packets, or even create custom diagrams.

### Pop-up Menu Of The “Packet Bytes” Pane

The 'Packet Bytes' pane is used to display the raw bytes of a packet in hexadecimal format. This pane provides an extensive set of features such as byte filtering, searching, and even customizable formatting.

### Pop-up Menu Of The “Packet Details” Pane

The 'Packet Details' pane is used to display detailed information about each packet including protocol headers, payload, and even custom fields. You can use this pane to inspect packets, analyze network traffic, or even troubleshoot network issues.

### Installing Wireshark on Linux

Installing Wireshark on a Linux single machine is relatively straightforward. There are several ways to install Wireshark, including installing from source code, using packages, or even compiling from source under UNIX or Linux.

### Building from Source under UNIX or Linux

Building Wireshark from source under UNIX or Linux requires basic knowledge of compilation and configuration options. You can use the following command to build Wireshark:

```bash

./configure --prefix=/usr/local/wireshark

make

sudo make install

```

### Installing from Packages under FreeBSD

Installing Wireshark on a Linux single machine using packages is also relatively straightforward. You can use the following command to install Wireshark:

```bash

sudo pkg install wireshark

```

### Reporting Crashes and Getting Help

Reporting crashes and getting help with Wireshark is easy. You can report crashes by sending an email to the Wireshark mailing list or even create a bug report on the Wireshark website.
