Outbound message too long when uploading files to apache sshd sftp server

When trying to upload files to an Apache SSHD SFTP server, you may encounter an error message stating that the outbound message is too long. This issue can be frustrating, but it has a simple solution. In this article, we will explain why this error occurs and provide step-by-step instructions on how to resolve it.

Understanding the Outbound Message Too Long Error

The outbound message too long error typically occurs when you try to upload a file to an Apache SSHD SFTP server that exceeds the maximum allowed size. By default, the maximum size limit for file uploads is set to a certain value, and if your file exceeds this limit, you will receive the error message.

This error can be caused by various factors, such as:

• The file you are trying to upload is too large.
• The server configuration has a low maximum file size limit.
• There may be network issues causing the error.

Resolving the Outbound Message Too Long Error

To resolve the outbound message too long error, follow these steps:

1. Check the file size: Verify that the file you are trying to upload is within the allowed size limit. If the file is too large, consider compressing it or splitting it into smaller parts.
2. Update server configuration: If the file size is within the limit, you need to update the server configuration to allow larger file uploads. To do this, follow these steps:
   1. Access the server where Apache SSHD SFTP is installed.
   2. Locate the configuration file, usually named "sshd_config".
   3. Edit the file using a text editor.
   4. Look for the line that specifies the maximum file size limit. It may be something like "MaxFileSize 100M".
   5. Increase the value to a higher limit, such as "MaxFileSize 500M" to allow file uploads up to 500 megabytes.
   6. Save the changes to the configuration file.
   7. Restart the Apache SSHD SFTP server for the changes to take effect.
3. Check network connectivity: If the error persists even after updating the server configuration, it is possible that there are network issues causing the problem. Check your internet connection and ensure that it is stable. You may also try uploading the file from a different network or using a different device.

By following these steps, you should be able to resolve the outbound message too long error when uploading files to an Apache SSHD SFTP server. If you continue to experience issues, it is recommended to seek further assistance from your system administrator or IT support team.
