To configure SFTP user permissions, follow these steps:
1. Create a new SFTP user account and assign a unique login ID and password.
1. Set the home directory for the SFTP user where they will be able to upload and download files.
1. Configure the permissions of the home directory to allow the SFTP user read and write access.
1. Optionally, configure the permissions of subdirectories and files within the home directory to specify what actions the user can perform, such as creating files or deleting them.
1. Configure SSH keys for the SFTP user to provide secure authentication.
1. Optionally, enable chroot jail to restrict the SFTP user to their home directory, preventing them from accessing other files on the server.
1. Test the SFTP user account to ensure that it can upload/download files and that the permissions are working as expected.
Note: The specific steps involved in configuring SFTP user permissions may vary depending on the operating system and SFTP server software being used. Consult the documentation for your software and operating system for detailed instructions.
