How to Fix: TFTP: Server Error: (2) Access Violation

TFTP server error fix for xinetd service

Quick Answer: Check the file permissions and ownership on the /tftpboot/ directory, ensure it matches the user specified in the xinetd config (root).

The TFTP server error '(2) Access Violation' is encountered when attempting to send a file using the tftp command. This issue affects users who have not manually created the required file on the server before sending it, leading to frustration and requiring troubleshooting.

This error can be frustrating as it prevents users from transferring files to the TFTP server without manual intervention. However, by following the steps outlined in this guide, users should be able to resolve the issue and send files successfully.

⚠️ Common Causes

  • The primary reason for this error is that the tftp command does not create the file on the server before transferring it. This is a limitation of the tftp protocol, which relies on the server having an existing file with the same name as the one being transferred.
  • Another possible cause could be issues with the xinetd service configuration or the permissions set for the TFTP service, but this is less likely given that manual creation works.

🚀 How to Resolve This Issue

Create a symbolic link to the required file

  1. Step 1: Create a new directory on the server if it does not already exist. This will serve as the location for the symbolic link.
  2. Step 2: Use the 'ln -s' command to create a symbolic link from the desired filename to the newly created directory.
  3. Step 3: Verify that the file can be transferred successfully using the tftp command.

Configure xinetd service to handle file creation

  1. Step 1: Modify the /etc/xinetd.d/tftp configuration file to include a 'create_dir' option. This will instruct the service to create the directory if it does not already exist.
  2. Step 2: Add the following line to the configuration file: `create_dir = yes`
  3. Step 3: Restart the xinetd service to apply the changes.

✨ Wrapping Up

To resolve the TFTP server error '(2) Access Violation', users can either create a symbolic link to the required file or configure the xinetd service to handle file creation. By following these steps, users should be able to send files successfully without manual intervention.
