Hi,

When i use ftp command in ftp prompt,i take the error follows;

ftp> dir
200 Port command successful.
421 Failed to create ActiveFTP Data Connection. (Blocked by firewall?) Please use PassiveFTP
ftp>

Because of this error, My shell script is not running
properly. How can i use passive ftp in my shell script and in ftp promt?

Thanks in advance,

What version of ftp are you using? Newer versions try to use passive ftp by default and only try to use an active mode connection when you specify the -A switch. You can specify the -p switch, which will tell ftp to use a passive mode connection. This switch is deprecated in newer versions, due to passive mode being the default, but it still works.

Strange client.
Also there is no "better method". One puts the security risk on the client, the other on the server.
