If this property value is True the channel used for data transfer (files, directory listings) will be encrypted, otherwise only command channel will be encrypted. Uncheck this and check the specified type of authentication you want to use. Some servers do not support our "auto authentication". When authenticating we normally try both Password and Keyboard authentication. This is the private key you have received from server administrator These options are only used when using Public key authentication. This property is only for some proxies that require ACCT value. If your connection does not require a username and password this box should be checked. When using SFTP together with public key authentication you have to specify a path to a private key file. For the FTP protocol only password authentication is available. Default port for Implicit FTPS is 990.Īuthentication type can either by password or public key. This is a descriptive name of the connection to distinguish from other connections. Note, brute force test option is only available for FTP protocol. When using FTP and you are unsure of connection properties you can use the Brute force test tool to test all connection combinations. SSL and TLS are protocols layered above connection protocols (such as TCP/IP) but beneath application protocols (such as FTP) that provide encrypted, authenticated communications between a client and a server. VisualCron supports both SSL 3.0 and TLS (SSL 3.1). Regular FTP offer no security and information is not encrypted. VisualCron is able to connect using regular FTP and FTPS (with implicit and explicit encryption). Servers that require an implicit SSL connection usually listen on port 990 rather than 21 When explicitly securing the connection, it is also possible to secure data connections using the overload of the Authenticate method which requires a DataChannelProtection ENUM as a parameter. Once the connection is established, it is necessary to authenticate before logging in, using the Authenticate method. In most cases, FTP servers that support SSL authentication will accept a normal connection on port 21. This is called an explicit SSL connection. In the second case, the connection is established in clear text and a special FTP command must be sent to the Secure FTP server to change the connection into a secure connection. This is called an implicit SSL connection. In the first case, the Secure FTP server may first require a SSL connection to be established, before the initial welcome message is sent. "Implicit SSL" versus "explicit SSL" (per RFC 2228)Ĭonnecting securely and authenticating are two distinct methods of establishing a secure connection with a FTP server. Dozens of FTP clients and automation utilities have since been developed for desktops, servers, mobile devices, and hardware, and FTP has been incorporated into hundreds of productivity applications, such as Web page editors. The first FTP client applications were command-line applications developed before operating systems had graphical user interfaces, and are still shipped with most Windows, Unix, and Linux operating systems. SSH File Transfer Protocol ("SFTP") is sometimes also used instead, but is technologically different. For secure transmission that hides (encrypts) the username and password, and encrypts the content, FTP is often secured with SSL/TLS ("FTPS"). FTP users may authenticate themselves using a clear-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host to another host over a TCP-based network, such as the Internet.įTP is built on a client-server architecture and uses separate control and data connections between the client and the server.
