Common Causes of the Error

The error message `sudo: error initializing audit plugin sudoers_audit` typically indicates an issue with the sudo configuration, particularly with the audit plugin that tracks sudo command usage. Understanding the common causes can help in troubleshooting the problem effectively.

  • Misconfigured sudoers File: The sudoers file might have syntax errors or incorrect settings that prevent the audit plugin from initializing.
  • Missing Dependencies: The audit plugin may rely on certain libraries or packages that are not installed on the system.
  • Permissions Issues: The permissions of the sudoers file or the directories containing the audit plugin might be incorrectly set, preventing proper access.
  • SELinux or AppArmor Restrictions: Security modules like SELinux or AppArmor could be enforcing policies that block the audit plugin from functioning correctly.

Troubleshooting Steps

To resolve the error, follow these systematic troubleshooting steps:

  1. Check the sudoers File:
  • Use `visudo` to edit the sudoers file safely. This tool checks for syntax errors before saving changes.
  • Look for lines related to the audit plugin and ensure they conform to the proper syntax.
  1. Verify Plugin Installation:
  • Check if the required audit plugin is installed:

“`bash
dpkg -l | grep sudo
“`

  1. Inspect Permissions:
  • Ensure that the sudoers file has the correct permissions:

“`bash
ls -l /etc/sudoers
“`

  • The permissions should typically be set to `440`.
  1. Examine Security Policies:
  • If SELinux or AppArmor is enabled, temporarily set them to permissive mode to see if the error persists. For SELinux:

“`bash
setenforce 0
“`

  • For AppArmor, use:

“`bash
sudo aa-status
“`

  1. Review Logs:
  • Check the system logs for any related error messages:

“`bash
less /var/log/auth.log
“`

Configuration Example

When editing the sudoers file, a correct configuration is essential. Below is a basic example that includes audit plugin settings:

Line Description
Defaults logfile=”/var/log/sudo.log” Specifies where to log sudo command usage.
Defaults !lecture Disables the initial lecture to users.
Defaults sudoers_audit Enables the audit plugin.

Ensure that these settings reflect your system’s requirements and security policies. Making these adjustments can often resolve the initialization error effectively.

Understanding the Error

The error message `sudo: error initializing audit plugin sudoers_audit` typically indicates that there is a problem with the configuration or the functionality of the sudoers audit plugin. This plugin is responsible for logging sudo command usage, which is crucial for security and compliance auditing.

Several factors can contribute to this error, including:

  • Misconfiguration in the sudoers file.
  • Corrupted or missing plugin files.
  • Incompatible versions of the sudo package or the audit plugin.
  • Insufficient permissions for the audit logging directory.

Troubleshooting Steps

To resolve this error, follow these troubleshooting steps systematically:

  1. Check the sudoers File:
  • Use `visudo` to edit the sudoers file safely.
  • Look for any syntax errors or misconfigurations.
  • Ensure that the audit plugin is referenced correctly.
  1. Verify Plugin Installation:
  • Check if the audit plugin is installed properly.
  • Use the command:

“`bash
sudo find / -name “sudoers_audit.so”
“`

  • If not found, reinstall the sudo package.
  1. Permissions Check:
  • Verify that the user running sudo has the necessary permissions to access audit logs.
  • Ensure that the directory for logs (usually `/var/log/sudo.log`) has appropriate permissions:

“`bash
ls -ld /var/log/sudo.log
“`

  1. Update Sudo:
  • Ensure that you are using an up-to-date version of sudo.
  • Update the package using your package manager:
  • For Debian/Ubuntu:

“`bash
sudo apt update && sudo apt upgrade sudo
“`

  • For RHEL/CentOS:

“`bash
sudo yum update sudo
“`

  1. Check System Logs:
  • Examine the system logs for any additional error messages or warnings that might provide more context:

“`bash
sudo tail -f /var/log/syslog
“`

Common Configuration Issues

Configuration issues can often lead to the initialization error. Here are common problems to watch for:

Issue Description
Invalid Syntax Any syntax error in the sudoers file can prevent proper initialization. Always use `visudo` for editing.
Missing or Incorrect Defaults Ensure default settings for the audit plugin are correctly defined. Missing defaults may lead to the plugin not functioning as expected.
Incorrect Plugin Path The path to the audit plugin must be accurate. If the plugin has been moved or renamed, it can lead to initialization failures.
