Unable to Submit Files via Rsync on Ubuntu VPS: Code 12 Error in Windows Terminal
Rsync is a powerful tool used for copying and synchronizing files between a local and a remote system. It is widely used in Linux and Unix systems, and it is also available for Windows. However, when using Rsync on an Ubuntu VPS through the Windows Terminal, you may encounter a "Code 12" error, which can prevent you from submitting files.
Understanding the Problem
The "Code 12" error in Rsync is typically caused by an issue with the SSH protocol. When using Rsync over SSH, the error can occur if the SSH daemon on the remote server is not running or if there is a problem with the SSH configuration. In some cases, the error message may not provide a clear explanation of the problem, making it difficult to troubleshoot.
Solution: Checking the SSH Daemon
The first step in resolving the "Code 12" error is to check the status of the SSH daemon on the remote server. To do this, you can use the following command:
sudo systemctl status sshIf the SSH daemon is not running, you can start it using the following command:
sudo systemctl start sshOnce the SSH daemon is running, you can try using Rsync again to submit your files.
Solution: Checking the SSH Configuration
If the SSH daemon is running and you are still encountering the "Code 12" error, the problem may be with the SSH configuration. To check the SSH configuration, you can use the following command:
sudo nano /etc/ssh/sshd_configThis will open the SSH configuration file in the Nano text editor. Check the file for any errors or inconsistencies, such as incorrect permissions or a missing host key. Make any necessary changes and save the file.
Once you have made any necessary changes to the SSH configuration, restart the SSH daemon using the following command:
sudo systemctl restart sshYou can then try using Rsync again to submit your files.
The "Code 12" error in Rsync can be caused by a problem with the SSH protocol. To resolve the error, you should check the status of the SSH daemon and the SSH configuration on the remote server. By following the steps outlined in this article, you should be able to submit your files via Rsync on an Ubuntu VPS without encountering the "Code 12" error.
