FTP Error DataStage 8.0

[Cosmos7127]

Hi,

I am trying to ftp a file from one server to another server. We have installed new DataStage 8.0 in our sandbox and testing our jobs. While testing the Ftp jobs getting the below error.

APT_CombinedOperatorController,0: Fatal Error: Fatal: Connection to the remote host's FTP server failed, DSTAGE-FTP-0023`:`host name not found

I tried hardcoding the server name, userid and password. Doesnt work.

Tried ftp thru Unix command prompt. It works.

Any help would be appreciated.
