[Former Member]

Hello ,

I am facing an error in communication channel while trying to post the file to the FTP server,

The error is " Message processing failed. Cause: com.sap.engine.interfaces.messaging.api.exception.MessagingException: An error occurred while connecting to the FTP server '10.100.5.00:20'. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 501 Unknown error'. For details, contact your FTP server vendor"

Please could you advice what need to be done to resolve this.

Thanks ,

Hi,

Check if there is any firewall between PI and the target application system(FTP).

Try to telnet the target and check the response message.

HI siva,

go to cmd ; ftp <ipaddress>

Enter username and password.

See the list of commands using help

enter Dir command to find out the current directory.

Use this directory in FTP adapter configuration.

Hi ,

FTP 501 Error is: "Syntax error in parameters or arguments"

Also, i see that the ftp address and port mentioned in your case is:

10.100.5.00:20

Hence, i see three probable issues here.

1. FTP Port :

Just check if the FTP server's port number '20' mentioned in your case is open as this is the data connection port. Moreover, the default port mentioned while creating a file channel is 21. Just check about the port number '20' with the FTP server administrator if this port number is opened and functioning.

2. FTP server address:

Also, try giving your FTP Server's address as 10.100.5.0

3. Also, check if the FTP server is reachable from the PI Server by using a simple ping command.
