[jira] [Commented] (FTPSERVER-433) Issues with data transfer for explicit SSL connections
[ https://issues.apache.org/jira/browse/FTPSERVER-433?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=13477730#comment-13477730 ] David Latorre commented on FTPSERVER-433: - I would suspect some bug in FileZilla. For instance, there is a bug in WinSCP (or the library it uses for SSL ) where , depending on the file size, the TLS_CLOSE_NOTIFY message is ill-formed. Java is a bit pick about this, and will throw an Exception in this case. What version of Filezilla are you using? Can you reproduce this problem with every version? Does this problem arise only for some file contents? (Write a text file of the same length as this one and with a character repeting itself as many times as necessary ... and check again ).

Re: [jira] [Commented] (FTPSERVER-433) Issues with data transfer for explicit SSL connections
Based on the file name you are uploading, I'm assuming it is 150 MB. If you have not done already, can you upload a small file and let us know the result? It appears that it might be something to do with the TLS_CLOSE_NOTIFY signal/message. Looks like the client (FileZilla) is negotiating for a TLS connection but closing the socket without sending the CLOSE_NOTIFY? Any SSL/TLS experts over there to validate/add more to this? Thanks.

Given you connect to localhost, I'm guessing that would exclude firewalls. You could run with SSL debugging enabled on the server, but I'm not sure that will tell you much more: -Djavax.net.debug=all http://docs.oracle.com/javase/1.5.0/docs/guide/security/jsse/ReadDebug.html Issues with data transfer for explicit SSL connections -- Key: FTPSERVER-433 URL: https://issues.apache.org/jira/browse/FTPSERVER-433 Project: FtpServer Issue Type: Bug Environment: Linux, java version 1.6.0_30, apache-ftpserver-1.0.5 Reporter: Søren Juul When using the sample configuration with SSL in explicit mode, some clients (e.g. FileZilla) have problems transferring.
