![]() ![]() To enable a list of users, you need to adapt the following functions that are included in this module: To add the module to your project, simply right-click on the Source group, select Add Net Item to Group, then click on User Code Template and scroll in the template files list until you find the FTP Server Multi-user template. All other accounts are created in a separate FTP_Server_Multiuser.c module. The default account defined in the Net_Config_FTP_Server.h file is a system administrator account, which has no restrictions. If you want to use multi-user authentication, you check the Enable User Authentication in the Net_Config_FTP_Server.h configuration file. The users which are allowed to access the FTP server are stored in an user database. The profiles define the access rights to different files on the FTP server. The multi-user login allows you to create different profiles for different users or groups of users. You need to adapt the function to the application's needs. It is part of the file FTP_Server_Access.c. ftp_server_ffind - find a file in a folder for printing a directory listing.įor access filtering the function ftp_accept_client is used.ftp_server_frename - rename a file from old to a new name.ftp_server_fdelete - delete a specified file.ftp_server_fwrite - write a block of data from the FTP data buffer to a file.ftp_server_fread - read a block of data from a file to the FTP data buffer.ftp_server_fclose - close a file that was previously opened.ftp_server_fopen - open a file for reading or writing.The following functions are implemented in this module: If you want to use another type of file system or to use a different storage media such as a hard disk, you need to add a similar file to your project. The file is preconfigured for the File System Component, so no modifications are required. All interface functions are located in FTP_Server_FS.c, which will be automatically added to your project's Network folder. The Embedded FTP Server can store files in a generic File System. User Application Notification sends notification about events in FTP server to the user application.Multi-user Authentication allows you to add additional user accounts and different access rights for each user.Access Filtering allows you to filter out the hosts, which are not allowed to connect to the FTP Server.The Embedded FTP server has integrated several advanced features: In this case, the File System Component must be used, and the Embedded Web Server must be properly configured. This mode is used, when the client is located behind a firewall and unable to accept incoming TCP connection.Īn embedded FTP Server can also be used to upload HTTP Web pages or to download log files to a remote PC. In passive mode the server sends the client an IP address and port number and the client opens the connection to the server.In active mode the client sends the server the IP address port number that the client will use for the data connection, and the server opens the connection.The mode of operation is defined by the command, received from the client. Various graphical user interfaces have been developed for all types of operating systems in use today.įTP can be run in active or in passive mode, which control how the data connection is opened. FTP is used with user-based password authentication or with anonymous user access.įTP file manipulation means that you can: create and delete files on FTP server, rename files, create folders and subfolders, print the folder listings, etc.įTP applications were originally interactive command-line tools with a standardized command syntax. FTP is built on a client-server architecture and utilizes separate control and data connections between the client and server applications.
