How to solve the problem that SFTP cannot obtain the directory in Linux?

SFTP is a file transfer protocol based on the SSH protocol. It transmits data through secure encryption, achieving more secure and reliable file transfer. SFTP can be used as an alternative to FTP or can be managed from a terminal for more flexibility. So what should I do if I cannot obtain the directory using sftp in Linux? Please see below for details.

If you cannot obtain the directory using SFTP in Linux, there may be several reasons. Here are several common solutions:

Check user permissions: Make sure that the SFTP login user has permission to access the directory. Run the ls-l command to check the directory permissions and owner information to ensure that the user has read permissions.

Make sure the path is correct: Verify that the path provided is accurate and matches the directory structure of the SFTP server. You can confirm the current working directory through the pwd command, and then use the ls command to view the directory contents.

Ensure that the firewall enabled on the system is properly configured to allow SFTP traffic through the specific port. You can check the relevant documentation or contact the system administrator for inspection and configuration.

It is important to check the SFTP server configuration. As an SFTP server administrator, you should carefully check the server's configuration files, such as the OpenSSH configuration file, to ensure that the SFTP function is enabled and the correct root directory is set.

5. Check the disk space: If the disk space of the partition where the target directory is located is full, SFTP may not be able to obtain the directory. Use the df
-h command to check whether there is enough disk space and clean up unnecessary files to free up space.
