What is file transfer protocol

File Transfer Protocol is a very common file sharing service that allows you to transfer your files from a storage device to an ASUSTOR NAS. The file transfer protocols supported by ASUSTOR NAS can be divided into: CIFS, AFP, NFS, WebDAV, FTP and FTPS.

The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

FTP

File Transfer Protocol Introduction

File Transfer Protocol is an extremely common file sharing service that allows you to transfer your files from The storage device is transferred to ASUSTOR NAS. The file transfer protocols supported by ASUSTOR NAS can be divided into:

CIFS (Network File Sharing System)

usually refers to SMB, SAMBA or Windows file services. CIFS is mainly used on Microsoft Windows computers , and Mac OS X computers. This service is usually built-in at the factory.

AFP (Apple File Transfer Protocol)

AFP is a method used on Mac OS 9 and Mac OS X computers to transfer files.

NFS (Network File Service)

NFS is a file transfer service used on Linux and Unix computers. If a Linux or Unix user wants to log in to your NAS, please enable this service.

FTP (File Transfer Protocol) and FTPS (FTP with SSL encryption)

FTP is widely used for uploading and downloading public files. After enabling the FTP server settings, you can log in to your NAS through any FTP client. You can also use a secure and encrypted FTP client to log in to the NAS and transfer data.

WebDAV

WebDAV is the standard for Web file management and is the abbreviation of web-based distributed authoring and versioning. It is a method that allows you to perform drag-and-drop file transfer through HTTP web browsing. This transfer method is very similar to how you transfer files on a standard Windows or Mac OS X computer.

In addition to the communication protocols mentioned above, ASUSTOR NAS also supports SSH and Rsync. SSH is a secure network transmission service that uses data packet encryption technology to encrypt the packets waiting for transmission before transmitting them to the network; Rsync is used to synchronize the files and directories of two computers and make appropriate use of Amount of backup to reduce data transmission

Extension information:

SFTP

SFTP: Secure File Transfer Protocol. Provides a secure encryption method for transferring files. sftp has almost the same syntax and functionality as ftp. SFTP is part of SSH and is a secure way to transfer files to the server.

The SSH software package already contains a secure file transfer subsystem called SFTP (Secure File Transfer Protocol). SFTP itself does not have a separate daemon. It must use the sshd daemon (the port number is default It is 22) to complete the corresponding connection operation, so in a sense, SFTP is not like a server program, but more like a client program.

SFTP also uses encryption to transmit authentication information and transmitted data, so using SFTP is very safe. However, since this transmission method uses encryption/decryption technology, the transmission efficiency is much lower than ordinary FTP. If you have higher requirements for network security, you can use SFTP instead of FTP.

SCP

SCP: SCP (Secure Copy): scp is secure copy, which is used for remote file copying, and the entire copying process is encrypted. Data transmission uses ssh, and uses the same authentication method as ssh, providing the same security guarantee.
