Transfer CFT puts the transfer on hold (K status). Transfer timeout and number of attempts will depend on the CFTTCP command RETRYW, RETRYNĪnd RETRYM parameters defining the network characteristics of the remote Transfer CFT responds to error codes from a proxy with: Must be declared in the CFTPARM command to be applied by Transfer CFT. The protocols (CFTPROT) and the networks (CFTNET) Transfer CFT only accepts outgoing calls.

If the connection if refused, the server immediately closes the connection. Once the connection is correctly established between the proxy and server, the client and the server are connected via the proxy and can perform transparent data inter exchanges (PeSIT, and so on). A response is sent to the client, indicating the request was successful or not. The proxy checks the connection request and either executes or rejects it.The client sends a connection request to the proxy, specifying the remote server IP address or host name and its port number.If authentication is refused, the server immediately closes the connection.

The sever response code indicates if the authentication was successful or not. The client authenticates itself using its username/password.The only method supported by Transfer CFT is username/password.

The client sends a list of methods it supports and the server responds to indicate which method it has chosen.

The client and server negotiate an authentication method for the client.

When using SOCKS5, the exchange between client and server consists of: Via the proxy and can perform transparent data inter exchanges (PeSIT, Once the connection is correctly establishedīetween the proxy and server, the client and the server are connected (the server is connected, the connection with the server has failed, the

The client logs into the proxy and sends.

When using SOCKS4, the exchange between client and server consists of: A briefĮxplanation of the SOCKS protocol is provided in this topic. Transfer CFT supports versions 4 and 5 of the SOCKS protocol.
