FTP Connection

A) Make your Internet connection is working. If you are behind a firewall, you have to connect to a server outside via firewall. Ask the administrator of your network and fill in the correct firewall information in the Options|Firewall tab. Some router-based firewalls require you to use PASV mode (for data transfer).

A) It is very likely the remote server is behind a router or a firewall. Switch TurboFTP to Passive Mode if you have not done so (enable [Options|Firewall|Use PASV mode]) or disable the Passive Mode if you are already using it, and connect again. If you still get the 425 error code, let us know the problem. 425 cannot open data connection problem

A) If your FTP server supports SSL/TLS, go to [Advanced Site Settings|Security|Secure Connection] specify the secure connection type your server supports, then launch the connection attempt as normal. After secure FTP connection is established, you will see a secure lock icon on the status bar. You can double-click on it to see the server's SSL certificate information.

A) In explicit SSL (or in TLS) the FTP client needs to send an explicit command ( i.e. "AUTH SSL" or "AUTH TLS") to FTP server to initiate a secure control connection; while in implicit encryption the client establishes secure control connection upon connection with the server. Default server port for implicit SSL is 990.

A) If you are using Wingate's FTP proxy, go to [Options|Firewall] and set the firewall type to be [USER with no logon]. In the "Host" field enter the name/address of the Wingate machine. In the "Port" field enter the service port number of Wingate. Also enable the "Use Firewall" option. The other options in this tab are not related to Wingate.
Above configuration applies to WinProxy's FTP proxy as well.

A) With ZoneAlarm you need to allow TurboFTP to connect to Local and Internet Zone (Program Settings|"Allow connect" column). Additionally you need to enable [Options|Firewall|Use PASV mode] in TurboFTP.

A) Currently TurboFTP supports FTP server running on the following platforms: Unix ( e.g. Solaris, FreeBSD, Linux, etc), Windows NT (support DOS style listing), VMS. Server type is automatically detected and this frees users from concerning about the type of server they are connecting to.

A) Go to Options|Advanced|Retry delay, set a new value (in seconds).

A) TurboFTP does not currently support HTTP. TurboFTP only supports FTP (ftp://) addresses.
