hi,

Cause

This situation is caused by the FTP server shutting down the connection when Passive mode is attempted and -PORT is not specified in the command line option override. This results in the inability to reconnect unless the map is restarted with a -PORT override.

Solution

Using Port Mode (-PT or -PORT) resolves this issue. The Port Mode adapter command (-PT or -PORT) specifies that only Port Mode is used for the FTP data connection. This is an older connection method and may be the only way to connect on older servers. By default, the adapter first tries to connect using Passive Mode; see the Passive Mode adapter command (-PV). If the adapter is unsuccessful, it uses Port Mode. During a Port Mode connection, the adapter listens for the connection and dictates where the server is to connect.

Thanks

Hi,

Check:

1) ping the ftp server ip address from the Command prompt.

2) check whether u have any firewall.

3) Check the port.

Hi,

There will be no problem in FTP channel. It is jsut giving error because the port 21 is not available on your server. You can check it with your adminstrator, try FTP server directly when you face this error, using command prompt.

I hope you are using data connection type as Passive.

You can also try to use permanent connection type.
