Is Novell aware that nwftpd 5.10 does not work with Filezilla 3.x when using SSL/TLS mode? Nwftpd 5.10 from December 2009.

The following message is observed from Filezilla 3.3.1 and nwftpd:

Response: 221 Closing Session
Error: GnuTLS error -9: A TLS packet with unexpected length was received.
Status: Server did not properly shut down TLS connection
Error: Could not read from socket: ECONNABORTED - Connection aborted

Please see the following:
FileZilla Forums • View topic - ECONNABORTED: It's the server's fault!

Also it's been reported on these forums already:

I've advised my users to stick with Filezilla 3.0.x or earlier. Unfortunately, many follow the automatic update prompts in Filezilla, update Filezilla, and then are confused why their Netware FTP connection no longer works. (FYI - we only allow connections via TLS so falling back to insecure is not an option.)

Can anyone notify Novell about this? I don't have a support contract.
