Implement Modified & Format Change

by ADMIN 35 views

Introduction

Cleek is a powerful tool for analyzing network traffic logs. However, sometimes users may encounter errors when implementing modified and format changes. In this article, we will explore the issue of "Modified & format change not implemented!" and provide a step-by-step guide on how to resolve it.

Understanding the Error

The error message "Modified & format change not implemented!" typically occurs when the user attempts to modify the format of the output using the -m option, but the format change is not implemented correctly. This can be frustrating, especially when working with large datasets.

The Problematic Command

The problematic command that triggers the error is:

~/code/cleek main*
¡ head ~/conn.log | cleek -m '(anonip! @o_h @r_h)' -f json

This command attempts to modify the format of the output using the -m option, but the format change is not implemented correctly.

The Desired Output

The desired output is:

{"ts":1.597767409403606e9,"uid":"CsxCam2xFf8TzMFsNh","id.orig_h":"101.134.20.105","id.orig_p":43272,"id.resp_h":"94.183.145.247","id.resp_p":80,"proto":"tcp","service":"http","duration":0.207774,"orig_bytes":77,"resp_bytes":2201,"conn_state":"SF","missed_bytes":0,"history":"ShADadFf","orig_pkts":7,"orig_ip_bytes":377,"resp_pkts":6,"resp_ip_bytes":2445}

This output is a JSON-formatted string that represents a single network connection.

The Solution

To resolve the issue, we need to modify the command to use the -m option correctly. The correct command is:

~/code/cleek main*
¡ head ~/conn.log | cleek -m '(anonip! @o_h @r_h)' | cleek -f json

This command uses the -m option to modify the format of the output, and then pipes the output to the cleek command with the -f option to format the output as JSON.

Breaking Down the Solution

Let's break down the solution into smaller steps:

Step 1: Modify the Format Using the -m Option

The -m option is used to modify the format of the output. In this case, we are using the anonip! @o_h @r_h format to anonymize the IP addresses.

Step 2: Pipe the Output to the cleek Command

The output of the first cleek command is piped to the second cleek command using the | character. This allows us to chain multiple cleek commands together to achieve the desired output.

Step 3: Format the Output as JSON

The second cleek command uses the -f option to format the output as JSON. This is the desired output format.

Conclusion

In conclusion, the issue of "Modified & format change not implemented!" can be resolved by modifying the to use the -m option correctly. By piping the output of the first cleek command to the second cleek command, we can achieve the desired output format of JSON.

Tips and Variations

Here are some tips and variations to keep in mind:

  • Make sure to use the correct format string with the -m option.
  • Use the | character to pipe the output of one cleek command to another.
  • Experiment with different format options to achieve the desired output.

Common Issues and Solutions

Here are some common issues and solutions to keep in mind:

  • Error: "Modified & format change not implemented!": Check that the format string is correct and that the -m option is used correctly.
  • Error: "Invalid format string!": Check that the format string is correct and that it matches the expected format.
  • Error: "Unable to pipe output!": Check that the | character is used correctly to pipe the output of one cleek command to another.
