Receiver FTPS (Explicit) channel giving error while writing files.

152 Views

Hi All,

We are facing an issue while using FTPS for writing a file to a partner location. Since this is the first time we are using FTPS, we went through some blogs and notes to configure the same, but still facing problems. Listed below are the steps undertaken for the configuration:

1. Got necessary ports opened on the firewall (the partner FTPS site uses explicit FTPS with control commands on port 21 and data on some custom ports).

2. Tested file transfer on FTPS using some FTPS client tools from the PI 7.11 server being used.

3. Uploaded the server SSL certificates in the NWA Keystore, Trusted CA view in both Base64 and normal formats (all certificates in the chain uploaded).

4. Configured the FTPS receiver channel for the CN name mentioned in the certificate, port 21, directory specified, NO X.509 client authentication (as that is not needed), AUTH TLS, USER,PASS,PBSZ,PROT as command order and using some authentication (user ID, Pwd for logging in).

But we are still getting the error:

'An error occurred while connecting to the FTP server 'xxxxxx.xxx.com:21'. The FTP server returned the following error message: 'com.sap.aii.adapter.file.ftp.FTPEx: 550 Access denied.'. For details, contact your FTP server vendor..'

On the partner side we could not find any logs and from PI too we are not getting any more details than mentioned above. CAn some let us know any known resolutions to the issue or how to get more details from the trace in PI (we have already increased the trace level of the file adapter to error but nothing more useful is available in Java default trace than mentioned above).

Appreciate any help extended towards this.

Thanks in advance,

Avishek.
