Wireshark Search for String in Info

When dealing with network issues, being able to quickly identify and analyze packets related to a specific transaction can be a game-changer. One powerful feature that allows you to do just that is the 'contains' operator in Wireshark's filter field.

By using this operator, you can search for a string within the content of various packet types, including IP, UDP, TCP, and more. For example, if you're trying to troubleshoot a slow network issue with a sales application, you might want to search for a specific string that identifies the customer transaction.

To do this, simply put the string in the Filter field and click on Apply. Wireshark will then filter out all packets that don't contain the specified string. This can be especially helpful when dealing with complex network transactions and numerous packets flying back and forth between different devices.

There are several ways to use the 'contains' operator in Wireshark, including:

* `udp contains “string”`: searches for the string in the content of any UDP packet

* `tcp contains “text”`: searches for the string in the content of any TCP packet

* `ip contains “string”`: searches for the string in the content of any IP packet, regardless of the transport protocol

* `frame contains “string”`: searches for a string in all frame content, independently of being IP, IPv6, UDP, TCP or any other protocol above layer 2

In addition to using the 'contains' operator, Wireshark also supports other features that can help you troubleshoot network issues. For example, the Date and Time-String Decoding feature allows you to decode date and time strings in packets.

Wireshark is a powerful tool that has become an essential part of my toolkit as a network administrator. Its ability to capture packets in real-time and display them in human-readable format makes it an invaluable resource for troubleshooting complex network issues. Whether I'm dealing with slow network speeds, dropped connections, or other problems, Wireshark is always on top of the list.

In summary, using the 'contains' operator in Wireshark's filter field can be a powerful way to quickly identify and analyze packets related to a specific transaction. By combining this feature with others, such as date and time decoding, you'll have even more tools at your disposal for troubleshooting network issues.
