FTPS failing with Error: ...FTPEx: 'AUTH TLS': command not understood !!

[Former Member]

Hi,

I am trying to send a file over FTPS (FTP using SSL/TLS) .

But it fails with the following error in RWB - Communication Channel monitoring:

Error when getting an FTP connection from connection pool: com.sap.aii.af.lib.util.concurrent.ResourcePoolException:

Unable to create new pooled resource: FTPEx: 'AUTH TLS': command not understood

I running NW711_05 and my FTP Connection Parameters are as follows:

Server: OurServerName

Port: 21

Data Connection: Passive {even tried Active but got the same error}

Timeout: 20

Connection Security: FTPS (FTP Using SSL/TLS) for control connection

X Use X.509 Certificate for Client Authentication

Keystore: service_ssl

X.509 Certificate and Private Key: ssl-credentials

Do I need to do any specific configuration/settings on the receiving FTP-server side?

Kind regards,

Joe

Hi,

For FTPS Port should be 990 ...also server name should be same as the one specified in the certificate...

if above not solves your error then search in the SDN for more details

Hi Rajesh,

Thx for your speedy response! I started out by deselecting the certificate checkbox and changing the port no from 21 to 990, this of course generated a different error message:

Unable to create new pooled resource: ConnectException: Connection refused

which I believe is because connection is not configured for port 990.

Anyone else has any suggestions as to how to proceed?

Regards,

Joe

What ftp server are you connecting to (I mean, what software is it running?). SSL-encrypted ftp isn't that commonly found out in the wild...

Hi it turned out that the FTP-server only supports SSH and not SSL/TLS so I need to find an "inexpensive" way to send/get files from a SSH ftp-server.

I read Daniel Gravensen's blog "SFTP with PI the openSSH way" and it seems to be the easiest way to go about doing it but because of my poor UNIX-script skills, I wonder if there is anyone out there that can explain to me exactly how to go about implementing it.

Kind regards,

Joe
